Urban Operations: An Historical Casebook

The Siege of Sarajevo, 1992-1995

by Major Curtis S. King

 

            Like all of the studies of this volume, the struggle for Sarajevo from 1992 to 1995 offers a unique perspective on Urban Operations (UO).  Within the wide range of UO, the siege of Sarajevo seems to fall at a mid-intensity level roughly halfway between full-scale house-to-house fighting and non-combat disaster relief.  Yet, perhaps more than most other entries in this collection, the three-year clash at Sarajevo can claim to represent the largest variety of UO in a single campaign.  At various times, the siege included moments of high-intensity street fighting, lengthy siege operations dominated by bombardments and sniper fire, and political posturing.  In fact, all of the factions in the Bosnian war found that operations in Sarajevo could serve more as a tool for propaganda than as a means for military advantage.  All the while, United Nations (UN) forces were involved in the struggle, initially in a limited and almost impossible effort to bring humanitarian aid to the city, and later in a more active peacekeeping and mediation role.

            The complexity of the conditions and conduct of the siege are a cautionary tale in and of itself--a lesson in the pitfalls of attempts to simplify the bitter war in Bosnia-Herzegovina and the role of Sarajevo in that fight.  Still, there are some themes that emerge from the conflict for Sarajevo that provide insight into urban operations.  First, the reluctance of all factions to commit to an intensive house-to-house struggle for the city reinforces the impression that urban fighting demands greater resources, especially manpower and ammunition, than battles on most other terrain.  Second, as the factions realized that they were unable or unwilling to pay the price for the complete capture of the city, they also discovered that they could still use the battle for the city for political gain.  This realization spawned a wide variety of tactical techniques that made little contribution to the capture or relief of the capital, but were designed to elicit political dividends.  Finally, in connection with the potential political advantages to be gained in Sarajevo, many of the combatants came to view the civilian population of the city as a chip in the game of Bosnian power politics.

            The siege of Sarajevo was part of a vicious war in Bosnia-Herzegovina (for brevity, hereafter referred to as Bosnia) from 1992 to 1995.  While historians have debated the supposed “ancient ethnic” origins of this war,1  the more immediate causes lay in the collapse of Yugoslavia after the death of Josip Broz Tito.  Since the Second World War, this former partisan leader had held together the diverse republics of Yugoslavia with a combination of propaganda, incentive, and brute force.  Without Tito, nationalistic movements reemerged and drove several of the republics towards independence.  This nationalism ultimately led to conflict among the newly independent states of the old Yugoslavia, and it was a key element of the political and military factors that dominated the fighting in Bosnia and the siege at Sarajevo (see Map 1).

            The first republic to leave Yugoslavia was Slovenia, which initially declared itself a sovereign state on 27 September 1989.  For the next year, there was high tension, but relatively light military conflict, between Slovenia and the Federal Government of Yugoslavia, which was becoming increasingly dominated by Serbia and its leader, Slobodan Milošević.  According to several accounts, Milošević agreed in January 1991 to allow Slovenia its independence primarily because there were so few ethnic Serbs in Slovenia.2  This decision revealed that Milošević had shifted from his earlier goal of maintaining a united Yugoslavia to a more nationalistic aim of building a “greater Serbia.”

            Croatia's assertion of independence in June 1991 was far less simple and much bloodier than that of Slovenia.  Most Croatians were Catholic, but helping to generate friction with Serbia, the new Croatian Republic also included a significant population of Eastern Orthodox Serbs located primarily in a region known as the Krajina.  In addition, parts of Croatia bordered Serbian and Bosnian Serb lands.  In the spring of 1991, Milošević and the Croatian President, Franjo Tudjman, maneuvered militarily and politically as conflict loomed between the two republics.  Milošević had the stronger military forces, while Tudjman hoped to portray the Serbs as aggressors to the international community.  At the same time, extreme groups on both sides sent forces to the Krajina to stir up passions among the local population.3  Open warfare broke out in the summer of 1991, and the brutality of the struggle came to be symbolized by the fight for Vukovar from September to November 1991.  After the fall of the city of Vukovar to pro-Serbian forces, Croatia and the Krajina Serbs (backed by the Serb Republic) came to an uneasy truce, and by early 1992, UN soldiers were in Croatia administering a ceasefire between the warring factions.

            The Croatian war exhibited several factors that influenced the war that later engulfed Bosnia.  First, at the highest political levels, both Milošević and Tudjman were flexible in tactics and goals.  They were capable of extreme nationalistic pronouncements and yet willing to sacrifice nationalistic allies for the sake of support from the international community.  Second, the fighting in Croatia transformed the Yugoslav Peoples' Army (known by the Serbo-Croatian acronym of JNA) from a multi-ethnic force fighting for a federal Yugoslavia to a pro-Serb force that supported Milošević's agenda for a greater Serbia.4  Additionally, one of the JNA's major commanders in Krajina who became familiar with the conditions of urban fighting was Ratko Mladić.  He later emerged as the overall Bosnian Serb commander at Sarajevo.  Third, the problems UN forces encountered after the ceasefire in Croatia prefigured the difficulties faced by UN forces in Bosnia.5  Their underlying neutral stance and their general lack of substantial military strength meant that they had to perform their mission with great awareness of political conditions and the limits of their own military power.

            Finally, pro-Serb forces used tactics in the battle for Vukovar that were similar to those later employed at Sarajevo.  The JNA showed its sympathies to the Serbs and used its heavy weapons outside Vukovar to bombard and devastate the city.  Serb paramilitaries (soldiers raised by Bosnian Serb leaders outside of official military structure) were more willing to do the urban fighting, but found that the cost of fighting from house-to-house was costly.  Though the Serbs had taken the city, the price for Vukovar was high, not only in the manpower and time expended but also in the international support lost in the effort.6  After Vukovar, the JNA and Serb paramilitary forces tended to rely on heavy weapons to bombard urban areas while remaining reluctant to commit to costly street fighting.

            Unlike Slovenia, which did not have a significant ethnic minority, and Croatia, which had a single and relatively concentrated Serb minority, Bosnia consisted of three ethnic groups, none of which commanded an absolute majority of the population.  According to the April 1991 census, Bosnia's ethnic mix was 43.6 percent Muslim, 31.3 percent Serb, 17.3 percent Croat, and 5.2 percent Yugoslav (this last category mainly representing people of mixed ethnic backgrounds).7  This demographic factor meant that no single ethnic group could rule Bosnia with an absolute majority making it difficult to create a workable unified political structure.  It was just as difficult to partition Bosnia along reasonable and simple ethic lines.  These ethnic groups were not divided into clearly defined geographic areas.  In the cities, especially Sarajevo, the ethnic groups were often intermingled, and in the countryside, the more ethnically homogenous villages dotted the landscape in a mixed fashion that defied a regional pattern.

            These problems had been apparent in Bosnia's first free elections in November 1990.  Each of the republic's three ethnic groups formed strongly nationalistic parties that dominated the elections, with the vote dividing almost strictly along ethnic lines (the one party that fostered multi-ethnic unity gathered few votes).  Thus, the Muslims captured the most votes, but not a majority, and after some complicated political maneuvering, one of the Muslim leaders, Alija Izetbegović, became Bosnia's President.8  The three national parties agreed to govern as a coalition, but relations were strained.

            The new coalition government in Bosnia watched events in Slovenia and Croatia with a careful eye.  Izetbegović initially had hoped that Bosnia could remain in Yugoslavia, along with Slovenia and Croatia, in an autonomous status.  However, once both Slovenia and Croatia had declared their independence from Yugoslavia, Bosnia was forced to choose between remaining in a Serb dominated rump Yugoslavia or declaring its own sovereignty.  By the spring of 1991, Izetbegović had become a proponent of an independent Bosnian state, while the Bosnian Serbs, under the leadership of Radovan Karadžić, preferred to remain a part of Yugoslavia.  The Bosnian Serb members of Parliament often boycotted legislative sessions, and finally on 14 October 1991, they left Parliament indefinitely.9 

            As nationalist elements gained ascendancy on all sides, the possibility for compromise diminished.  The Bosnian Serbs threatened to create their own Bosnian state if Izetbegović pushed towards independence, and they called on the JNA to protect the four self-declared Bosnian Serb autonomous regions within Bosnia.  Ironically, Izetbegović also tried to woo the JNA to his side, hoping that the Federal Army could prevent the intervention of the Serb paramilitaries.10  These efforts collapsed.   Subsequently, Izetbegović, perhaps hoping for international recognition and protection, called for a referendum on Bosnian independence, which took place on 29 February and 1 March 1992.  Karadžić and the Bosnian Serb leadership called for a boycott of the referendum.  Most Bosnian Serbs did not vote, and the overall turnout was 64 per cent.  However, the Muslims and Bosnian Croats voted almost unanimously for independence.11  The day after the vote, at a Bosnian Serb wedding ceremony in Sarajevo, Muslim gunmen killed a member of the wedding party, and tension in the city reached a new high.  The factions managed to avoid open fighting in Sarajevo for another month, but by late spring, war seemed inevitable.

            In the events leading up to the outbreak of the war, each of the major factions and their leaders staked out their positions, which was to have a considerable influence on the siege of Sarajevo.  Alija Izetbegović, the Bosnian Muslim leader, wanted a united and independent Bosnia--multi-ethnic, but with Muslims as the largest segment of the population.  Radovan Karadžić, leader of the Bosnia Serbs, initially pushed for all of Bosnia to remain in a Serb dominated Yugoslavia, but by 1992, his aim was to partition Bosnia and bring the Serb regions, as a contiguous unit, into Yugoslavia.  This goal required the physical relocation of significant parts of the ethnic populations and the use of “ethnic cleansing.”  This term came to describe a wide variety of actions—including threats, house burnings, beatings, rape, and executions—designed to force opposition ethnic groups out of a region, thus leaving that area ethnically pure.  These actions were not a full-scale policy of genocide, but were usually designed to create larger, contiguous regions populated by single ethnic groups.  In the Bosnian war, the Bosnian Serbs were the first to employ this tactic, but all factions eventually engaged in ethnic cleansing.  For his part, Milošević initially supported Karadžić because they shared the common goal of a greater Serbia; however, the occasional conflicts between these two leaders grew worse as the war continued.  Karadžić tried to keep some measure of independence from Belgrade for the Bosnian Serbs while Milošević distanced himself from the Bosnian Serbs when their ethnic cleansing brought increasing international pressure and economic sanctions.

            The final Bosnian faction, the Bosnian Croats, wavered between supporting the Muslim and Serb sides.  In the independence referendum and at the opening of the war, the Bosnian Croat leadership supported the concept of a multi-ethnic Bosnia, but the idea of a partition--with segments of Bosnia being incorporated into newly independent Croatia--was always a possibility.  The Bosnian Croat leader, Mate Boban, supported partition, but the Croatian president, Tudjman, had firmer control over his Bosnian counterpart than Milošević had over Karadžić.  For his part, Tudjman appeared to be the ultimate opportunist, willing to support any policy in Bosnia that benefited Croatia.  He wavered between a partition that could add parts of Bosnia to Croatia and keeping a unified Bosnia as a buffer between Croatia and Serbia.  The one constant for Tudjman was to support any action that could aid in the recovery of the Krajina.

            The role of actors outside of Bosnia also had a major influence on the conflict.  The most obvious external players were Serbia and Croatia, whose political goals clearly influenced (but did not control) the policies of their Bosnian clients.  Just as importantly, the Bosnian Serbs and Bosnian Croats could count on military support from contiguous benefactor states.  This support included heavy weapons and money.  Additionally, the JNA was clearly a pro-Serb force, and it would be the crucial force that enabled the Bosnian Serbs to lay siege to Sarajevo.  The Muslims, for their part, had no adjacent ally, and Izetbegović hoped that the international community, primarily the UN and North Atlantic Treaty Organization (NATO), would aid the Muslim side.  However, a UN arms embargo on Bosnia actually hurt the Muslims the most because they started the war with no heavy weapons and could not smuggle them in from adjacent allies.  Later in the war, Izetbegović’s forces would get some support from Muslim nations that managed to get weapons through the embargo.

            All of the factions in Bosnia with all of their varied aims fought for more than three years.  During this time, the fighting spread to almost every region of the country, but throughout the conflict, Sarajevo remained a focal point of the struggle and the most visible symbol of the war.

            During the siege, as it does today, the city of Sarajevo stretches out along both sides of the Miljacka River in a narrow, oblong shape approximately 13 kilometers long from east to west, but generally only 3 to 4 kilometers wide as it follows the river (see Map 2).  The urban area contained virtually all of the types of terrain and structures that are found in most modern cities.  However, the truly dominant characteristic of the city was the ring of mountains surrounding it, placing the city in a bowl visible and vulnerable to anyone who occupied the rim of high ground on the outside edges.  Keeping in mind that there was only limited fighting in the streets of Sarajevo itself, it is worth examining key pieces of terrain that influenced the siege both militarily and politically.12

            Transportation routes into and out of the city, rivers and roads, provided only limited capacity.  The Miljacka River, like almost all watercourses in Bosnia, was non-navigable, and thus Sarajevo had no port facilities.  The Bosnian capital was roughly divided in half by the river.  The Miljacka is a tributary of the Bosna River, which along with the Željeznica River bounded the city on its western border.  There were numerous bridges across the Miljacka throughout the city, including the famous “Latin Bridge” where Archduke Franz Ferdinand was assassinated.  The Miljacka was only a limited barrier to movement between the northern and southern portions of the city and played only a minor role in the siege.

            The major roads of the city were a much larger factor in the struggle.  As might be expected, Sarajevo was (and is) a nexus of major highways for Bosnia (see Map 3).  Two roads led out of the city north towards Tuzla, a major Bosnian Serb stronghold, and Zenica, one of locations designated as a safe haven by the UN.  Towards the east, one highway connected the city with Višegrad, and more importantly Pale, which was the capital of the Bosnian Serb faction within Bosnia (later to be called the Republika Srpska, or RS in its Serbo-Croatian acronym).  One major route from the city passed near the airport and continued south to Trnovo, Foča, Dubrovnik, and Split.  This was the main path connecting the city with Bosnian Croat strongholds, and to a lesser extent, the Muslim ones in the south.  Finally, the main road to the west connected Sarajevo with Mostar, the scene of some of the bitterest fighting of the war when Bosnian Croats and Muslims turned against each other in 1993 and 1994.  All factions, as well as the UN, used the roads to attempt to transport supplies and humanitarian aid and to evacuate refugees, children, the sick, and the elderly.

            One other road, the infamous "sniper's alley," is also noteworthy.  Starting in the west, the road name changed several times until becoming Marshal Tito Boulevard as it entered the old city.  This was the main east-west path through the city.  It was not a highway, but for much of its route, it was a wide, four-lane street with a median in the middle for the city's tram.  From its origins on the west side of the city up to the point where it split near the “old city,” the street was an open area that was visible from many high buildings and most of the surrounding mountains and thus vulnerable to sniper fire.  The single, ground level tram down the center of the boulevard was Sarajevo's only internal mass transit system, but as a transportation line, often did not run during much of the siege and had little effect on the fight for the city.  However, the tram cars were sometimes turned on their sides and used as obstacles and barricades.

            Looking at the various sectors of the city, one can start with the western area of Sarajevo, which was best known during the siege for the suburb of Ilidža and the Sarajevo airport.  Ilidža is split by the Željeznica River and at the time of the siege, consisted of modern residential homes and small apartment buildings.  Its most famous site is a spa consisting of several hotels that served as a Bosnian Serb headquarters during much of the siege and later was the headquarters for the multinational Implementation Force (IFOR) that replaced the United Nations Protection Force (UNPROFOR) in 1996.  The airport lies slightly east of Ilidža, and like the highways emanating from the capital, its significance at the time was more political than military.  Neither side used the airport for combat aircraft nor military supply, but it became a symbol of contact with the international community and a major connection for humanitarian aid.

            Just north and east of the airport was the sector of the city known as Dobrinja.  It consisted largely of three- and four-story apartment complexes.  The open area of the airport on the southwest side of Dobrinja gave clear fields of fire from the surrounding mountains, and much of Dobrinja was devastated in the course of the siege.  This part of the city also became known for being the eastern end of a tunnel that ran under the airport.  The Bosnian (Muslim and Croat) forces built the tunnel to aid in the resupply of the city while avoiding the Bosnian Serb guns that dominated the region around the airport.  It is also interesting to note that the tunnel was the one rare example of underground operations in the siege; Sarajevo did not have a subway and had only a small sewer system.  Unlike some other urban conflicts, Sarajevo saw virtually no subterranean fighting.

            Just north of Dobrinja, but still south of the Miljacka River, was the area of town known as Novi Grad.  Most of this sector was made up of housing for the industrial laborers of the city, and it included several massive apartment buildings built in the old communist style of repetitive, high-rise structures.  These tall buildings provided perches for snipers from all of the factions.  Also in this region was the Oslobodjenje building, the home of Sarajevo's pro-Bosnian (Muslim) press, which was devastated in the siege.  Farther east was the Postal, Telephone, and Telegraph (PTT) building, which was the headquarters for UNPROFOR during part of the siege.

            Moving farther east in the city past residential apartments and moderately sized buildings on both sides of the Miljacka, the center of the city contained several areas and structures that figured prominently in the struggle.  On the north side of the main east-west boulevard (sniper’s alley), lay Tito Barracks—a  complex of large concrete buildings that housed the old Yugoslav Army (JNA) garrison for the city.  Close by was the Holiday Inn, which gained fame as the favorite location for the international press during the conflict.  Slightly farther east were two high-rise buildings called the Unis, also known locally as “Mono” and “Uzier,” two famous characters from jokes told by Sarajevo's residents.  Although tall, the Unis buildings were not a popular site for snipers because they were subjected to heavy mortar and artillery fire throughout the struggle.  Across the boulevard from the Holiday Inn—but still north of the Miljacka—were the Parliament Building and National Museum.  These buildings received only moderate damage during the fighting; the Muslim defenders held trench lines closer to the river rather than occupying the structures themselves.  Just across the Miljacka from the Parliament and Museum was the district of Grbavica, a residential area of mostly two- and three-story apartments.  This district marked the farthest advance of the Bosnian Serbs into the city itself.

            Continuing eastward towards the old sector of the city, a road called Alipašina branched north from the Marshal Tito Boulevard.  This road climbed rapidly upward towards mountains on the north side of the city.  About two kilometers from the center of the city, the Alipašina passed two stadiums built for the 1984 Olympics: the Koševo outdoor stadium, and the Zetra indoor ice rink.  Across the Alipašina from the stadiums was a large open hillside that contained a small cemetery before the siege.  During the war, many of the dead bodies were stored in Zetra stadium before being buried on the hillside across from the rink.  Often, snipers killed mourners during these funeral processions.  By 1995, the cemetery was four times its original size.

            Returning to the area near the intersection of the Alipašina and Tito Boulevard, there were two significant buildings: the Residency and the Presidency.  Neither structure is particularly large nor militarily important, but both had political significance.  The Residency was Tito's old vacation home in the city, and it later functioned as UNPROFOR headquarters.  The Presidency was the office of Bosnian President Izetbegović during the war.

            Finally, one comes to the eastern sector of the city, a mixture of closely packed residential buildings, stores, and famous historical structures centered on the Muslim old city known as Baščaršija.  The old city was interlaced with numerous narrow streets and cobblestone pedestrian paths.  On the eastern tip of this sector, a large stone building constructed in the Austro-Hungarian era (1894) as the City Hall later became the city's library.  Though not a major factor in the siege, the building suffered heavy artillery fire, which tragically destroyed a substantial number of priceless books.  Just west of the library, the most prominent Muslim mosque, Catholic cathedral, and Orthodox church lay within 500 meters of each other—miraculously little damaged during the war—perhaps symbols of the potential for peaceful coexistence.  Near these places of worship lay a more tragic symbol, the central market place (the Markale market), a small open area (a square about 200 meters on all sides) filled with wooden stands for produce and other vendors.  It had no military importance, but bombings of the market and the resultant civilian deaths had a great impact on the politics of the siege.

            The high ground surrounding Sarajevo was the dominant terrain of the struggle.  During the siege, almost every road to Sarajevo had to go through a pass dominated by mountains controlled by the Bosnian Serbs.  The most publicized of these high points was Mount Igman on the southwest outskirts of the city.  Two other sectors of elevated terrain stand out.  First, on the south side of the city, the Bosnian Serbs held a series of hills starting at Lukavica and continuing east past the location of the bobsled run of the 1984 Olympics.  Control of these southern heights gave the Bosnian Serbs their best artillery and sniper shots into the city.  Second, although the Bosnian Serbs also controlled much of the high ground on the northern half of the city, the Bosnian Muslims held one hilltop less than a kilometer from the Zetra Stadium, which was also the location of the Bosnian television broadcasting station.  This station continued to broadcast throughout the siege.

            As mentioned earlier, the population of Sarajevo was cosmopolitan and relatively tolerant of religious differences.  Its ethnic groups extensively intermingled throughout the city.  According to the 1991 census, the total population was 428,617.  Sarajevo had a relatively small land area for a major urban area, and therefore, was more densely populated than many comparable cities.  As in the nation at large, the Muslims made up the largest percentage of the city population at 49.3 percent.  The Bosnian Serbs were 27.4 percent of the total.  Interestingly, the Yugoslav percentage of the city population (12.1) was greater than the Croat portion (7.3).  This factor shows that a sizeable segment of Sarajevo’s population was the product of mixed ethnic backgrounds.  Finally, 3.9 percent of the city was listed as “others,” which included a small but growing Jewish population.

            Prior to the siege, the distribution of the ethnic groups throughout Sarajevo was so mixed that almost no sector, with the one exception of the old city (Baščaršija), could claim a majority of one faction.  The large apartment buildings had people from each group, and the residential areas usually had Muslim, Orthodox, and Catholic homes side by side.  However, not long after the siege began, segments of the population shifted.  In particular, significant numbers of Bosnian Serbs left their homes to seek safety behind Bosnian Serb lines around the city.  Thus, in addition to the old city, a few other sectors of Sarajevo became predominantly Muslim and subject to bombardment.

            The opposing forces at Sarajevo were a mix of military, paramilitary, pseudo-military, armed civilian, and even some criminal elements that represented the myriad of factions vying for control of the city.  For simplicity, it is useful first to discuss the concept of Total National Defense and then each of the factions' forces in turn: the JNA, Bosnian Serb irregulars, Croat and Bosnian Croat units, and the Muslim-dominated forces initially designated as the Bosnian Defense Force (BDF) and eventually renamed the Army of the Federation of Bosnia and Herzegovina (known by its Serbo-Croatian acronym of AFBiH).  After examining the factions, one will then examine the other major player in Sarajevo: UNPROFOR.  Scrutiny of the leadership, organization, weaponry, doctrine, training, and experience of all of the fighting elements reveals a general lack of UO preparation and a shortage of the resources (and in some cases the will) needed to carry out a sustained city fight.

            Before its breakup, Yugoslavia's armed forces were based on a concept called Total National Defense.  Not surprisingly, this concept grew out of Yugoslavia's experience in the Second World War, as well as the nature of the country's terrain and Yugoslavia's position as a non-aligned player between the Soviet Union and U.S. in the Cold War.13  Under Total National Defense, the active army (JNA) was not expected to defeat a major power in a conventional war.  Instead, the JNA acted more as a training vehicle for conscripts who became members of the Territorial Defense Force (TDF) after completing their two year term in the JNA.  The TDF, fighting as partisans, was expected to carry the bulk of the fight against any invader (much like in the Second World War).

            The forces needed for Total National Defense doctrine had several unique characteristics.  Both the JNA and TDF trained in small unit tactics with an emphasis on partisan warfare.  The TDF was locally based and reflected the ethnic composition of its region.  The JNA was multi-ethnic (at least before 1990) and answered to the Yugoslav federal government.  The TDF had access to small arms caches that were distributed throughout the country, with a particular concentration of weapons in the rugged terrain of Bosnia, while the JNA had all of the heavy weapons (tanks, armored personnel carriers, artillery, and mortars).  As the Yugoslav wars evolved after 1990, the TDF fragmented into supporting its local regions, while the JNA generally became more of a pro-Serbian force.

            When fighting broke out in Sarajevo in April 1992, the Yugoslav Federation controlled the JNA units in Bosnia.  By this time, Slovenia and Croatia had departed Yugoslavia, leaving the Federation dominated by Serbia, and thus Milošević had a preeminent influence on the JNA's role.  This being said, it is important to emphasize that the JNA, especially at the outset of the war, was not simply an unquestioning tool of Serbian nationalism.  It still contained some non-Serbian officers and several moderate Serb officers who hoped to restore Yugoslav unity or at least to mitigate the suffering in Bosnia.  Additionally, at the beginning of the Bosnian war, the Bosnian Serb leader, Karadžić, had only limited influence on JNA operations.  Finally, not long after the fighting erupted in April 1992, the federal government ordered the JNA to withdraw from Bosnia.  However, only limited parts of the JNA withdrew while many of the JNA soldiers and the bulk of their heavy equipment remained behind and eventually became the basis of the Bosnian Serb Army (later known by its Serbo-Croatian acronym as the VRS).14 

            Just as fighting erupted in Sarajevo, General Ratko Mladić, a veteran commander of JNA forces fighting in Croatia, became the JNA commander in Bosnia.  Mladić was a clear Serb nationalist who had no hesitations in taking whatever measures he felt were necessary to eradicate Croat and Muslim opposition in Bosnia.  Initially, as a JNA officer, he reported to the Yugoslav government, but he did all that he could to support the Bosnian Serbs.  Later in 1992, when parts of the JNA departed Bosnia and the rest became the Army of Republika Srpska (VRS), Mladić received command of this new force.  At that point, he no longer kept up the façade of Yugoslav unity, and he worked directly for Karadžić.  Mladić remained the VRS commander for the rest of the war.

            The JNA leader in the Sarajevo region was Colonel-General Milutin Kukanjac.  While he disliked Izetbegović and the new Muslim dominated Bosnian government, Kukanjac focused on protecting and preserving his JNA forces and was uninterested in taking the city by storm.  He seemed to have a genuine interest in acting as a moderating force, but he nonetheless permitted Bosnian Serbs to occupy dominant positions in the hills around Sarajevo, gave them heavy weapons, and occasionally assisted in bombarding the city.  Kukanjac’s actions reflected the mixed role of the JNA at the beginning of the war.

            The fighting in Slovenia and Croatia had prompted a significant reorganization of the JNA in December 1991 that had a major influence on the composition of Kukanjac's forces around Sarajevo.  The Yugoslav Federation shuffled its old Military Districts (MD) and created a new Military District, the 4th MD, to operate in Bosnia with its headquarters at Sarajevo.15  The 4th MD was actually redesignated once more before April 1992 when it became the 2nd MD.  It consisted of four corps and approximately 60,000 men throughout Bosnia.  The 4th Corps was positioned at Sarajevo and consisted of 15,000 to 20,000 men.  These soldiers reflected a transition in the composition of the JNA in 1991 and early 1992; the JNA lost its multi-ethnic mix as Muslim and Croat soldiers, and particularly officers, left the Federal Army or were purged by the dominant Serbian leadership.  By the time fighting broke out in Sarajevo, the 4th MD consisted largely of Bosnian Serb, Serb, and Montenegrin soldiers.  (Montenegro was the only Yugoslav republic to remain with Serbia in the rump Yugoslavia that remained after 1992).

            The JNA forces were the best equipped of any of the factions fighting for Sarajevo, to include possessing heavier weapons systems than those of UNPROFOR.  While there are rough estimates of the total number and types of JNA equipment throughout former Yugoslavia (about 800-900 tanks, 740 Armored Personnel Carriers [APCs], 6,400 mortars, and about 1,300 field guns), it is difficult to estimate the numbers available for the Sarajevo fight.  Simple mathematics would indicate that the 2nd MD in Bosnia might have had about one quarter of the JNA totals, while the JNA troops at Sarajevo had only a portion of the 2nd MD's total (for example, perhaps 50 tanks, 400 mortars, and 80 field guns).  In any case, the JNA at Sarajevo deployed a wide mix of heavy weapons systems that included T-34, T-54/55, and M-84A tanks; wheeled and tracked APCs from both western and former Soviet stocks; some multiple rocket launchers; an extensive variety of artillery and mortars (from 60mm up to 155mm); and Gazelle and Mi-8 helicopters.  The number and types of JNA equipment may not seem impressive, but this was virtually the only heavy equipment available in the siege for any of the factions.

            By April 1992, the JNA was in the process of transforming its role and doctrine based on experiences in Slovenia and Croatia.  The federal army was no longer a training ground for multi-ethnic conscripts to join the TDF.  Instead, the JNA became a force of long-term Serb and Montenegrin soldiers whose mission was to support the Serb-dominated federal government in Yugoslavia's internal wars.  Despite this change in roles, the JNA transformation was incomplete.  It still carried traditions of partisan doctrine and training (small unit actions, decentralized control), and in any case, it lacked the numbers to conduct a large-scale conventional war in Bosnia's rugged terrain.  Increasingly, the JNA relied on its heavy weapons to destroy, or intimidate, its opponents while Bosnian Serb irregulars did the close fighting.  The JNA, like all of the factions in Sarajevo, had no special OU training or doctrine.  Some of the JNA officers had seen the high cost of the fighting in Vukovar, and they were reluctant to commit their forces in house-to-house fighting in Sarajevo.

            The Bosnian Serb irregular forces were initially more aggressive than the JNA and more willing to engage Izetbegović's Bosnian forces in urban combat.  However, they lacked the strength necessary to take the city, and after parts of the JNA converted to a Bosnian Serb force, the irregulars adopted the JNA tactics that relied on heavy weapons in order to avoid casualties that might result from a city fight.

            To imply that all of the irregulars in support of the Bosnian Serbs at Sarajevo were Bosnian Serbs under Karadžić's control is an oversimplification.  While most of the irregulars were probably Bosnian Serb, some were Serbians, Montenegrins, and even Croatian Serbs who were fighting for the overall cause of Serb nationalism.16  Karadžić certainly had more control over most of these units than he had over the JNA, but due to the disparate nature of the irregulars, the Bosnian Serb political leader never had complete command of them.

            Similarly, the Bosnian Serb irregulars did not have a unified military commander in April 1992.  The most infamous of the irregular leaders went by the nom de guerre of "Arkan" (his real name was Želiko Ražnjatović).  He commanded a unit known as the “Tigers,” similar to other irregular units called the “White Eagles” and “Panthers.”  Although Arkan did not participate significantly in the siege at Sarajevo, the collection of virtually independent battalion level commanders like him at Sarajevo only loosely reported to Karadžić while intermittently working with the JNA.

            The irregulars were mostly light infantry, and they began the war in Bosnia with sufficient quantities of small arms and ammunition but limited numbers of heavy weapons.  However, they could often count on the support of JNA weaponry, and in fact, they inherited most of the 4th MD's equipment when the JNA ostensibly withdrew from Bosnia.  Estimates of Bosnian Serb irregular strength vary between 20,000 and 35,000 throughout all of Bosnia, thus leaving a very rough estimate of 4,000 to 8,000 men immediately available for the fight in Sarajevo.  These forces usually operated in battalion-size units or smaller, and it was difficult for the Bosnian Serb leadership to coordinate the irregulars' efforts.

            Reflecting their light infantry structure (and aspects of their former partisan training), the Bosnian Serb irregulars relied on a small unit doctrine that emphasized sudden attacks on enemy weak points while avoiding decisive confrontations with enemy strengths.  The irregulars did not have a specific UO doctrine, but some of the units deployed near Sarajevo had fought in built-up areas in Croatia and probably knew more about city fighting basics (for example, methods for clearing a building) than the JNA.

            Overall, the Bosnian Serb irregulars presented an unusual combination of characteristics.  They were more ideologically motivated than most of the JNA soldiers, and they had some city fighting experience; thus they seemed more likely to engage, and succeed, in a house-to-house struggle for Sarajevo.  However, their numbers were limited, their units and leadership were divided, and heavy casualties in the urban battles of Croatia had tempered their enthusiasm for city fighting.

            Croat and Bosnian Croat forces had less influence on the conflict in Sarajevo than in other parts of Bosnia because the Bosnian Croats tended to focus on terrain that was adjacent to Croatia, particularly Herzegovina.  At the start of the Bosnian war, there were two Bosnian Croat armies fighting in Bosnia: the Croatian Defense Forces (HOS) and the armed forces of the Croatian Defense Council (HVO).  The HOS started as local paramilitary units, while the HVO clearly had closer ties with the more regular units of the Croatian Army (HV).  In August 1992, the HOS merged with the HVO.  Their combined forces often wavered between supporting the Muslims and the Bosnian Serbs, depending on the political situation.17  A group of moderate Bosnian Croats, under Stjepan Kljuić, supported Izetbegović, but a large percentage of Bosnian Croats, particularly those in Herzegovina, sided with the more nationalistic Mate Boban.  As the Bosnian Croats shifted their support, they had a significant, but not decisive, effect on the siege.

            Overall, the HVO was under the political control of Boban, and just as Boban clearly relied on the support of Croatian President Tudjman, the HVO often called on the assistance of the HV in its campaigns.  In addition, the HVO command to a large extent seemed to answer to orders from the HV main staff in Zagreb.  The HVO was organized on a territorial basis, with locally recruited soldiers serving close to home.  They had some heavy weapons and were generally better armed than the Bosnian (Muslim) forces and less well armed than the Bosnian Serbs.  HVO doctrine carried some of the old partisan traditions, and—except in Mostar—the troops proved reluctant to engage in city fighting.  The HVO’s overall strength in Bosnia was about 35,000 troops, but few of these troops took part in the siege. 

            The only HVO force in the Sarajevo region was a regiment of 2,000 men in the suburb of Stup.  During the siege, these troops did not directly engage in city fighting or even in the shelling of Sarajevo.  Their main effect was in holding one of the resupply routes into the city.  Throughout 1992, the HVO forces in Stup usually allowed Bosnian (Muslim) convoys to proceed to the city.  For parts of 1993, the HVO closed this route as part of the bitter Muslim-Croat fighting of that year.  However, after the Washington Accord between Muslims and Croats in February 1994, the route was reopened to Bosnian supplies.  Some Bosnian-Croat soldiers who served in Izetbegović’s forces had a more direct role in the fight for Sarajevo, as will be discussed later in this chapter.

            The forces that supported Izetbegović's Bosnian government were usually more numerous than their opponents, especially in the Sarajevo region, but they started with little organization and experience and were woefully lacking in equipment and heavy weapons.  Before the outbreak of fighting in Bosnia, paramilitary Bosnian Muslim units such as the “Green Berets” and the “Patriotic League of the People” had formed in Sarajevo and other Muslim dominated regions in Bosnia.  However, the bulk of the BDF came from former TDF soldiers and local police forces.  In any case, the BDF had to start virtually from scratch, taking elements from a variety of sources.18

            The ad hoc nature of the early BDF makes it difficult to determine its exact structure, strength, equipment, and ethnic composition.  On this last issue of ethnic composition, writers and observers of the Bosnian war have offered widely varying views of Izetbegović's forces.  Some accounts portray the BDF as a true multi-ethnic force that reflected the Bosnian government's desire to tolerate an inclusive Bosnian unity.  Other works argue that only a small number of Bosnian Serbs and Bosnian Croats joined Izetbegović's forces, usually because they were coerced, and that the Bosnian government made a cynical show of multi-ethnic participation without sharing any real power.  There are elements of truth in all of these accounts, but in the end, the Bosnian government—even if only out of necessity—was the only faction that made any effort to incorporate all of Bosnia's ethnic groups.  Only a few Bosnian Serbs continued to serve in the BDF, but the Bosnian Croats made up a significant percentage of the BDF units.  During the siege, Bosnian Croat units serving in the BDF do not appear to have openly turned on the Muslim forces and engaged them in combat, but in several cases Bosnian Croat units refused to cooperate with BDF attacks and gave tacit assistance to the Bosnian Serbs.

            Whatever the post facto arguments of BDF composition, most accounts agree that Izetbegović's Bosnian government was the least prepared faction at the outbreak of war in April 1992.  The Green Berets were available, but were small in number.  At first, Izetbegović negotiated with the JNA, perhaps naively, in an attempt to woo it to the Bosnian side, and thus neglected efforts at building his own force.  It was his belated recognition of the need for more substantial Bosnian forces that led to his call for mobilization of the Bosnian TDF and police forces on 4 April 1992, which was the immediate cause (or excuse) for the outbreak of the war.  Even after these events and the significant fighting that continued for two months, it was not until 26 June that the Bosnian government declared a formal state of war.

            Initially, the Bosnian government relied on three types of forces to hold Sarajevo: Muslim paramilitary units, TDF and police forces (containing some multi-ethnic troops), and Muslim ‘criminal’ elements.  This last group, as might be expected, have been the subject of much controversy, with some accounts portraying the Izetbegović government as nothing more than a collection of Muslim thugs.  While some members of the Bosnian government (and Izetbegović's family) probably had connections to organized crime, the use of Muslim gangs seems to have come more out of military necessity than profit.  In any case, the initial defense of Sarajevo fell to disparate units that were ill-equipped, lacking in centralized control, and untrained in UO doctrine.  However, perhaps borne out of desperation, the Bosnian troops showed a willingness to engage in costly street fighting in order to hold the city.  Many of these soldiers also had the advantage of knowing the terrain—as residents of Sarajevo—and thus felt more comfortable in a city fight for their own neighborhoods.

            It was only after the outbreak of fighting that the Bosnian government began the process of structuring its forces and formally created the Bosnian army (later to be known as the BDF).  The commander in chief of the Bosnian forces was President Izetbegović, and his defense minister was Jerko Doko, a Bosnian Croat.  While the political leaders provided overall guidance, the details of the fighting were left to the Bosnian main staff in Sarajevo.  The chief of staff was Colonel Safir Halilović, a Muslim, and his two deputies were Colonel Stjepan Šiber, a Bosnian Croat, and Jovan Divjak, a Bosnian Serb.  Almost all members of the main staff had been former members of the JNA or TDF.  Although the main staff divided control of the BDF into seven district staffs with one located in Sarajevo, the main staff and the Bosnian government stayed in Sarajevo throughout the war, and they exercised what amounted to direct control of the defense of the city.

            Arms and equipment were a constant problem for the BDF.  At the beginning of the conflict, small arms and ammunition were barely adequate at best while heavy equipment (artillery, mortars, tanks, and APCs) was almost nonexistent.  This is part of the reason for the Bosnian government's willingness to turn to organized crime in Sarajevo where the local "mafia" provided small arms to the pro-government forces.  The UN embargo on arms hurt the Bosnian government more than its enemies because Bosnia began the war with the fewest weapons on the ground, and it did not have an adjacent benefactor nation to supply it arms.  Beginning in late 1992, Izetbegović turned to other Muslim nations (especially Arab) to help finance the purchase of arms and ammunition, some of which were smuggled through Croatian ports.  Although the BDF was never as well equipped as its adversaries, the Bosnian forces eventually acquired some T-54 (and later, T-62) tanks; APCs; 60mm, 82mm, and 120mm mortars; a hodgepodge of old Yugoslav and former Eastern bloc artillery pieces; and the Soviet-designed RPG-7 as well as German and Yugoslav antitank missiles.

            The pro-Bosnian forces did not have UO doctrine or experience at the beginning of the war, although the units fighting within the city had the advantage of fighting on familiar terrain.  As the BDF became more structured, it does not seem to have adopted any formal UO doctrine; but the units within the city became more experienced in urban fighting, thus making any Bosnian Serb attempt to take the city more difficult as the war progressed.

            UNPROFOR soldiers rarely engaged the factions in direct combat during the siege; however, they engaged in various activities such as convoy escort and guarding the airport, and their mere presence at key points in the conflict had a significant influence on the struggle for the city.  UNPROFOR units were in Sarajevo at the onset of hostilities almost by accident, as UN leaders chose the Bosnian capital as the headquarters of the peacekeeping forces deployed in Croatia (for the Krajina conflict) over the objections of UNPROFOR's military leaders who felt that Sarajevo was too far from Croatia.  Thus, UNPROFOR troops in Sarajevo were initially only a small headquarters guard force not intended for intervention in Bosnia's conflict.19

            The UNPROFOR commander in 1992 was Lieutenant General Satish Nambiar, an experienced Indian officer.  His deputy was a flamboyant French officer, Major General Philippe Morillon.  Both Nambiar and Morillon were focused on the deployment of UNPROFOR in Croatia.  They spent most of their time outside of Sarajevo, and they were not heavily involved with UN operations in the city in the early months of the Bosnian war.  By default, the UNPROFOR officer most involved in the early fight for Sarajevo was third in the UNPROFOR hierarchy, Brigadier General Lewis MacKenzie, a Canadian officer with considerable experience in peacekeeping operations.

            In accordance with their initial mission in Sarajevo as an administrative headquarters, UNPROFOR forces located in the Bosnian capital were small.  The staff included officers and support personnel from multiple nations.  The only real fighting force in April 1992 was a company-size unit of Swedish guards whose mission was to protect the headquarters.  These guards performed their mission admirably, but clearly UNPROFOR lacked the physical strength to influence events in the city, and MacKenzie had to rely mostly on negotiation, persuasion, and bluff to have some restraining effect on the conflict.  The initial small UNPROFOR force was located in the PTT building in downtown Sarajevo.

            Although UNPROFOR gained some strength as the war progressed, it never had the mission of direct military intervention.  This increased strength included troops from several nations who occupied the airport, and a French battalion at Mount Igman that endeavored to keep this dominating height neutral.  All of the UN contingents that rotated through service in Sarajevo came with their own national equipment.  This included sufficient small arms, some APCs, and wheeled vehicles, but no heavy weapons (tanks and artillery).  Towards the end of the siege, the main source of military striking power for UNPROFOR became NATO airpower.

            Describing the full course of the siege of Sarajevo presents unique challenges.  The conflict lasted over 30 months--along with Leningrad, arguably the longest siege of the 20th Century.  Events of some importance occurred almost each day including bombardments and sniper fire, yet neither side made an effort to achieve a decisive victory within the city's urban environment.  Perhaps the best way to capture the importance as well as the feel of the struggle for Sarajevo is to trace the siege chronologically with a focus on three areas: major attempts to take the city or lift the siege, efforts taken to cut or open supply lines into Sarajevo, and actions that had significant political effects on the conflict.

            Although tensions had been mounting for some time in Bosnia and armed conflict had erupted in Bijelina, Bosanski Brod, and other locations in early April, all of the factions seemed unprepared for the outbreak of fighting in Sarajevo.20  On 4 April, Izetbegović made preliminary steps towards mobilizing the Bosnian TDF—on paper, still accountable to the Yugoslav government—in support of his Bosnian government.  The next day, students and other residents from all of Sarajevo’s ethnic groups conducted a peace march along Tito Boulevard that protested the nationalistic policies of each of the factions’ political leaders.  Snipers from the Holiday Inn fired on the crowd, killing a young medical student from Dubrovnik, Suada Dilberović, the “first casualty” of the siege.  Muslim police entered the Holiday Inn and arrested several armed Bosnian Serbs.  Also that day, Bosnian Serb “paramilitaries” attacked the Sarajevo Police Academy.

            All sides now scrambled to mobilize forces.  On 6 April, the same day that the European Community (EC) formally recognized Bosnia, Izetbegović completed the mobilization of the Bosnian TDF and called on the Sarajevo Police to support the Bosnian government.  The Sarajevo chief of police, Dragan Vikić (a Muslim), took nominal command of the combined TDF and police forces and issued a decree that attempted to reassure the city’s population: “the defenders of Sarajevo will not open fire on members of the Yugoslav People’s Army and will not pose a threat to any citizen.”  However, another account claims that Vikić was far less sanguine and felt that the situation in Sarajevo was “out of control.”  Bosnian Serb paramilitaries began setting up checkpoints and roadblocks on the roads surrounding the city, and they seized control of the airport.  The JNA took little action largely because its forces were divided and positioned in several locations.  At the outbreak of the fighting, a large part of Kukanjac's troops were located at Tito Barracks near the center of the city.  Bosnian forces quickly surrounded these soldiers, and Kukanjac devoted much of his effort to getting them out of the city.  Another large element of the federal army was located in the barracks at Lukavica, and these soldiers also hesitated to join in the city struggle.  The rest of the JNA was split into smaller units and positioned in the mountains surrounding the city.  The divided positions of the JNA hindered its ability to make a concerted effort in the fighting. 21

            After Izetbegović declared a state of emergency throughout Bosnia on 7 April, the JNA stepped up its air strikes on Sarajevo's suburbs.  Still, the JNA ground troops within Sarajevo remained quiet while pro-Muslim forces (TDF, police, and irregulars) set up roadblocks throughout the city.  By 8 April, Bosnian roadblocks controlled the routes within the interior of Sarajevo, and Bosnian Serb roadblocks on the perimeter of the city controlled access from the outside.  At the same time, Izetbegović called for the formal organization of the Bosnian Defense Force (BDF), and he declared that any irregular forces in Bosnia not submitting to the control of the Bosnian Ministry of Interior were considered "enemies."  In effect, the Bosnian President was condemning the use of Bosnian Serb paramilitaries, while trying to avoid the complete alienation of the JNA “regular” forces.22

            As the opposing sides settled into their positions for the siege, there were some last minute attempts at compromise.  Kukanjac, perhaps concerned for the safety of his troops at Tito and Lukavica Barracks, declared that paramilitaries were the main cause of the conflict (he did not specify which faction's paramilitaries), that the JNA's main aim was "protecting the town and citizens from clashes and so forth," and that the JNA would not bombard Sarajevo.  Although this last claim proved hollow, Kukanjac seems to have genuinely hoped to minimize the conflict.  As the JNA preached moderation to an extent, Izetbegović met one of Karadžić's key subordinates, Momćilo Krajišnik, in Sarajevo to attempt an eleventh hour agreement.  The discussions came to naught, and Krajišnik left the city.  He would not return for almost three years.23

            For the next several weeks, there was sporadic fighting in and around the city.  Mostly this took the form of air and artillery bombardments, and sniper fire.  None of the factions endeavored to take the city by storm.  The Bosnian forces were far too weak and fully engaged in the effort of building the strength of their army, the JNA forces in the center of the city remained in their barracks, and the Bosnian Serb irregulars devoted their efforts to strengthening the ring around the city.  The JNA retained control of the airport and kept it closed for part of the month.  All sides put up more and more checkpoints and road blocks, but no clearly discernable front line separated the opposing forces.24

            The situation changed in early May with two major events: a substantial assault on the city by the Bosnian Serbs and the kidnapping of Bosnian President Izetbegović.  The Bosnian Serb attack on 2 May 1992 seems to have been intended to split the city in two, and it coincided with offensives throughout much of the rest of Bosnia.  For the assault on Sarajevo, the Bosnian Serbs advanced in two columns of armored vehicles.  One column came from the south out of Vraca and the Trebovic mountains.  It advanced into the district of Grbavica and attempted to cross the Miljacka river at Skenderija.  The other column advanced from the west, near the airport, and appeared to be aiming for the Oslobodjenje building.  Both columns were supported with mortar and artillery fire.25  This fire support probably included JNA units surrounding the city, but Kukanjac’s troops in the barracks within the city did not join in the attack.  Clearly, the Bosnian Serbs and the JNA were reluctant to engage in a dismounted house-to-house fight; they relied on troops mounted in armored vehicles, supported with heavy indirect fire.

            The results of the attack were some limited gains against ill-equipped, but desperate Bosnian resistance.  The western column advanced far enough to take the suburbs of Nedarići and Mojmilo, and isolate the suburb of Dobrinja near the airport.  However, this column stalled quickly once it ran into more serious Bosnian defenders in and around Dobrinja.  The eastern column pressed its attack with more determination.  It reached the river, took all of Grbavica, and even fired some tank rounds into the Presidency building.  Nonetheless, Bosnian TDF, police, and Muslim irregulars—armed with a few crucial anti-tank weapons—fought from the surrounding buildings and halted the advance.  One key shot took out a lead Bosnian Serb vehicle on one of the narrow streets leading to the bridge at Skenderija, thus blocking a large part of the attacking force.  Other portions of the Bosnian Serb attackers were reluctant to advance into kill zones, and they would not dismount to clear the defenders from the surrounding buildings.  Although the ground attacks had stopped, the heavy shelling continued throughout 2 May and into the next day.  One report claimed that the shelling was the worst yet in the war, "setting buildings ablaze and covering streets with debris and shrapnel."26

            The Bosnian Serb attack revealed several aspects of the fight for Sarajevo.  First, whether from doctrine and experience on the costs of taking a city, or from a simple lack of ground soldiers, the Bosnian Serbs showed that they were going to rely heavily on armored vehicles and firepower.  In fact, they grew more reluctant to commit any forces (armored or otherwise) into the urban area, and for the rest of the siege, they put most of their effort into fighting on the perimeter of Sarajevo in order to close routes into the city.  Second, the Bosnian Serb difficulties confirmed the vulnerability of armored columns without dismounted support in an urban fight.  Armored vehicles gave the Bosnian Serbs mobility (but only on the roads), protection against small-arms fire, and additional firepower from mounted machineguns and tank main guns.  But they were too vulnerable to hand-held antitank weapons and bombs that could be thrown from adjacent buildings.  The armored columns needed to be teamed with dismounted infantry to clear the buildings and with engineers to clear obstacles and mines.  Finally, although the Bosnian Serbs ultimately failed in their goal to split the city, they made significant gains in many of their other offensives throughout Bosnia.  They came to realize that Sarajevo had a large symbolic value to the Izetbegović government, as well as the Western media, and that they could use the city as a diversion for their more general goal of partitioning the rest of Bosnia.

            The other crucial event of early May, Izetbegović’s kidnapping, also helped shape the future fighting in Sarajevo.  The Bosnian President was returning from negotiations in Spain on 2 May when, after several delays, his flight landed at the Sarajevo airport.  Usually, an UNPROFOR escort would pick up Izetbegović to take him to the Presidency building, but after waiting several hours (and perhaps thinking that the heavy fighting had canceled the flight), the escort had departed.  The President had now fallen into the lap of the JNA, who controlled the airport.  From Tito Barracks, Kukanjac ordered the JNA commander at the airport to detain Izetbegović and move him to Lukavica Barracks.  At first, Izetbegović refused to go to Lukavica.  In a bizarre sequence of events, while Izetbegović argued with his captors, a phone call from a woman in downtown Sarajevo rang at the airport desk.  She was calling to see about canceled flights, but Izetbegović quickly picked up the phone and held the following remarkable conversation:

            “Good evening Madam, this is Alija Izetbegović, the President of Bosnia on

            the phone.”

               There was a brief pause.  She was confused.  He said, “Yes, yes.  That's

            right, Alija Izetbegović, the President of Bosnia.  Could you please be so

            kind, I am here at the airport, sitting in the director's office, and the Army

            won't let us go.  We are kept here.  Could you please call the Presidency

            and tell them that you talked to me, that I am here, at the airport, and if you

            can't reach the Presidency, please call radio and TV and inform them.”27

 

Amazingly, the astonished woman informed both the Presidency (Izetbegović's deputy, Ejup Ganić eventually got the word of the kidnapping) and local television and radio stations, which broadcast the “detention” to Bosnia and the West.  Izetbegović, concerned for the safety of his daughter who was detained with him, later agreed to go to Lukavica, but the unusual phone conversation at the airport, and the subsequent publicity, certainly gave him some leverage in negotiating his release.

            While the Bosnian President wrestled with his situation, Kukanjac telephoned Belgrade for guidance.  The JNA leader was not interested in removing Izetbegović from power, but he asked for and received permission to use his captive as a bargaining chip in getting the JNA troops out of their city barracks.  Kukanjac told the press that he wanted a ceasefire and exchange of Izetbegović that would allow the JNA to "pack and peacefully leave the centre of Sarajevo."28 

            The UNPROFOR commander in Sarajevo, MacKenzie, acted as a mediator and helped to arrange the exchange between Kukanjac and Izetbegović.  UNPROFOR elements in Sarajevo were still basically headquarters units with minimal security (the main peacekeeping mission remained in Croatia), and MacKenzie wanted to keep the UN intervention to a minimum.  After much arguing, the plan was for a column consisting of a few UNPROFOR APCs along with 20 empty JNA vehicles to escort Izetbegović and his daughter from Lukavica to Tito Barracks.  The convoy would then pick up Kukanjac and a large segment of the JNA garrison and return to Lukavica (where they could later be moved outside of the city altogether).  Along the way, a part of the convoy with the UNPROFOR escort would break off and bring Izetbegović to the Presidency building.

            Not unexpectedly, the convoy did not go exactly as planned on 3 May—in his diary, MacKenzie called 3 May "the worst day of my life."  The initial leg of the journey to Tito Barracks proceeded relatively well.  Once at Kukanjac's headquarters, there were delays and additional demands from Kukanjac (he wanted to evacuate a larger number of men), and confusion between Izetbegović and Ganić over whether the Bosnian Government could guarantee the convoy's safety.  The convoy finally left Tito, and within about one kilometer, it came under fire.  The Bosnian forces wanted to disarm the JNA troops in the convoy, but Kukanjac refused.  Neither the small UNPROFOR escort nor the road-bound JNA had the capability to battle the Bosnian forces that controlled the buildings surrounding the convoy.  Even with the tension and some casualties, cooler heads prevailed.  Izetbegović switched to another vehicle and MacKenzie dismounted to help diffuse a confrontation farther back in the column.  After moving about another kilometer, some of the UNPROFOR vehicles, along with Izetbegović and his daughter left the column and arrived safely at the Presidency building.  The main column was hit once more before reaching Lukavica.  Kukanjac managed to keep the convoy moving, and it finally arrived late that night.  After its arrival, JNA and Bosnian Serb mortars and artillery unleashed a heavy barrage on the city.  Overall, twenty-five were killed and wounded during the exchange and over ninety JNA soldiers taken prisoner (most of whom were exchanged by 5 May).29

            The kidnapping and convoy ambush had a major impact on the combatants.  Izetbegović finally abandoned all hope of using the JNA as a moderating force in the conflict and was convinced that he needed to build the Bosnian units (the BDF) into a force capable of defending his government on its own.  For their part, the old-guard members of the JNA, including Kukanjac, were only too happy to get out of Sarajevo and the rest of the Bosnian conflict.  Following a major reorganization of the JNA on 8 May, the Serb-dominated government of Yugoslavia removed most of the old Titoist officers.  This date also marked the beginning of the official withdrawal of the JNA from Bosnia; however, as noted earlier, most Bosnian Serb soldiers of the JNA remained behind, along with much of their heavy equipment.  They joined the Bosnian Serb irregulars to form the VRS and came under Mladić's command (and Karadžić's control).  Those JNA forces that did not remain behind conducted the initial part of their withdrawal from Sarajevo between 19 and 25 May with some harassment at Bosnian checkpoints along the way.30  After May, the lines separating Bosnian Serb forces surrounding the city and Bosnian forces within Sarajevo were set—with only minor changes—for the rest of the siege.

            In addition, the kidnapping and convoy incident illustrated the primacy of political factors in the war.  It hardened the positions of all of the factions and soured the attitude of the UNPROFOR leadership.  Even at the tactical level, political considerations came to the fore.  The UNPROFOR-JNA convoy of vehicles was completely at the mercy of the Bosnian forces—particularly so in the urban environment where the Bosnians held the buildings that dominated the road.  This had nothing to do with an unsure UN mission or supposedly restrictive rules of engagement (ROE); UNPROFOR would have needed large numbers of ground troops ready to fight house-to-house to guarantee the safety of the convoy.  However, the Bosnian militia did not annihilate the convoy, partly because of political repercussions.  In fact, although pundits have criticized Izetbegović, Kukanjac, and MacKenzie over their role in the convoy ambush, all three leaders effectively used persuasion rather than military force to keep a bad situation from getting out of control.

            For the next several weeks, sniper fire and bombardments punctuated several on and off ceasefires.  On 27 May, shell fire hit a group of Sarajevo citizens lined up outside of a store.  The incident gained notoriety in the West as the "bread queue bombing” and placed the Bosnian Serbs in a negative light.31  At about the same time, another series of artillery strikes received less publicity, but a recorded radio conversation revealed that the purpose of Mladić's VRS bombardments was clearly psychological and political:

            Mladić [to Colonel Vukasinovic, artillery chief]: Are you up there?

            Vukasinovic: Yes, everything is ready.

            Mladić: Which weapons have you got ready?

            Vukasinovic: I have those up there, in Kresa.

            Mladić: What can you hit?

            Vukasinovic: I can fire all the way to the garrison.

            Mladić: Do not fire at the garrison.  Can you pound Velesici?

            Vukasinovic; I can.

            Mladić: Are your guns pointed toward the target?

            Vukasinovic: They are.

           

            Mladić: And tell me, can you pound Baščaršija [the old Muslim, historic area]

            Vukasinovic; I can.

            Mladić: What?

            Vukasinovic: Yes, no problem.

            Mladić: Keep the Presidency and the Assembly building under steady, direct

               fire and pound slowly in intervals until I give the order to stop.32

 

Mladić was clearly more concerned with destroying historic, cultural, and political targets than he was with striking at the enemy's military forces (the garrison).

            At the end of May and early June, negotiations for the withdrawal of the last JNA elements from Tito Barracks continued while bombardments and sniper fire grew more intense.  MacKenzie recorded in his diary that "Things are heating up.  Very heavy fighting in Sarajevo" and "All hell has broken loose in Sarajevo.  Heaviest shelling yet."  A London Times account confirmed "the worst night of shelling in almost two months of seige."33  That same Times article also reported a Bosnian Serb attack on the coastal town of Dubrovnik.  As was to happen on several occasions, a major Bosnian Serb offensive in some region of Bosnia coincided with actions in Sarajevo, thus dividing the attention of the Western media and the international community.  On 5 June, the last remnants of JNA troops at Tito Barracks, perhaps 300 soldiers, departed the city during a brief ceasefire. Shortly thereafter, the Bosnian Serbs unleashed a particularly heavy bombardment aimed at Tito and nearby locations that appeared to be targeted at destroying JNA equipment left behind by the evacuation.34

            As the JNA departed the center of the city, it also negotiated with UNPROFOR and the Bosnian Presidency for a turnover of the Sarajevo airport.  These negotiations proved tortuous.  An initial trilateral agreement on 5 June fostered optimism within UNPROFOR's leadership and among the citizens of Sarajevo.35  However, both the Bosnian Serbs and the Izetbegović government obstructed the implementation of the agreement, and fighting around the airport continued.36  Tactically, the JNA troops at the airport were subject to harassing fire from the three- to five-story apartment buildings in the adjacent pro-Bosnian community of Dobrinja.  Yet, the JNA could retaliate with heavier weapons such as tanks positioned at the airport as well as artillery and mortars in the hills to the south and west.  Neither side needed the airport for military purposes—the factions lacked combat aircraft, and the airport was too vulnerable to ground fire to be a good base for such tactical aircraft.  Given this situation, the withdrawing JNA had no desire to hold the airport, but they and the Bosnian Serb forces hoped to extract as much political benefit as possible from the “concession” of turning over the airport to UN control.  At the same time, Izetbegović's Bosnian government seemed just as interested in provoking the JNA and Bosnian Serbs into retaliations and bad publicity as in letting UNPROFOR control the airport.

            A dramatic visit to Sarajevo by French President François Mitterand helped to give UNPROFOR control of the airport.  Mitterand's appearance illustrates how much the political machinations of the warring factions dominated their military actions.  The JNA, Bosnian Serb irregulars, and pro-Izetbegović forces could have easily stopped the French President's visit; they all had the ability to sweep the airport runways with direct and indirect fire.  Instead of choosing military options, the fighting factions seemed to focus on the benefits of gaining favor with Mitterand and Western opinion.37  While the French President's visit was delayed while UNPROFOR frantically tried to negotiate his safe arrival, Mitterand finally arrived in Sarajevo on 28 June.  He had originally planned to meet only with Izetbegović, but UN representatives scrambled to ensure that he also saw Karadžić.  Both leaders gave Mitterand their standard speeches.  After listening to their combination of pleas and harangues, the French President departed the next day.

            While some accounts portray Mitterand's visit as self-serving, the French President deserves credit for considerable personal courage as well as helping to push the factions into fulfilling the terms of the airport agreement.  Soon after his visit, the fighting around the airport was considerably reduced, and UNPROFOR was able to occupy it at the end of the month.  Though under UNPROFOR control throughout the rest of the siege, the airport still came under bombardment and had to close on several occasions.  However, it is significant that the Bosnian Serbs did not attempt to cut completely this line of communication from the West to the city.  Again, they may have feared the political repercussions, and perhaps they thought that they could better use the city as a diversion with Western journalists and relief efforts focused on Sarajevo.

            At the end of June, the Bosnian forces (now officially the BDF) made their first serious effort to break the ring around the city.  The main attack was in the suburb of Vraca, but it failed after only modest gains.  The BDF lacked heavy weapons (although they made moderate use of mortars for the first time), and the VRS forces, using inherited JNA weapons, had too much firepower to be dislodged.38  Two other factors may have influenced the battle.  First, Vraca is a suburb of small residential buildings that lies on the outskirts of the city.  Thus, the terrain—while still containing buildings—was more open than the more constricted area near the city center, thus favoring the larger firepower of the VRS.  Second, the BDF command complained that the Croatian units of the BDF were not supporting their attacks—a complaint voiced even earlier by deputy commander, Jovan Divjak.

            After this attack, Sarajevo settled back into its siege routine for a few months.  During this time, the UN approved an expansion of the UNPROFOR mission that finally added Bosnia to the original mandate for peacekeeping in Croatia.  The new, combined UN forces were designated UNPROFOR-2 (although for simplicity this paper will continue to refer to it as UNPROFOR).  Many of the Canadians, including MacKenzie, rotated out of Sarajevo, and a mixed force of troops from Egypt (Muslim), France (Catholic), and Ukraine (Eastern Orthodox) took over peacekeeping duties in Bosnia and Sarajevo.  Lt.Gen. Nambier retained overall control of UNPROFOR, and his former deputy, French Maj. Gen. Morillon took command of the forces in Bosnia from MacKenzie after a short interlude.  Morillon soon moved the headquarters of UNPROFOR from Sarajevo to the smaller town of Kiseljak.  In fact, the new commander of UNPROFOR's Bosnian contingent—though active in many confrontations in Bosnia, particularly Srebrenica—seemed little concerned with events in Sarajevo and had little influence on the siege.  The new UN forces in Bosnia totaled 1,500 troops with perhaps fewer than 300 in the capital--larger than the original headquarters in Sarajevo, but still far too small to attempt to enforce the UN mission through force of arms.39

            At the end of August, the Bosnian Serbs unleashed some of their heaviest bombardments coinciding with the opening of the London Peace Conference (a new round of peace talks hosted in the British capital).  One series of strikes killed 11 and wounded 55.  Another barrage left 14 dead and 126 wounded in downtown Sarajevo.  During this heavy fire, the BDF made an attempt to open a reliable lifeline to the city.  They employed an armored train on the rail line through Ilidža, but the Bosnian Serbs repulsed their attack.  Also during this time, the Bosnian Serbs targeted the Bosnian National Library with indirect fire and destroyed priceless books and manuscripts representing Bosnian culture.40

            After the heavy shelling of August, which culminated a flurry of activity that had started in April, the city settled into a tragic routine of bombardments and sniper fire.  Often, it was difficult to pinpoint the origins of this fire, and all of the factions used this uncertainty to accuse their opponents of unprovoked aggression.  On the Bosnian (pro-Izetbegović) side, the lack of heavy weapons and the disadvantage of positions in the low ground of the city did not allow for the use of indirect fire.  It appears that the pro-Izetbegović forces often shifted their mortar positions within the city, perhaps aided by observation from the radio television building which was located on the one piece of high ground in Bosnian hands--the hill just northwest of Zetra stadium.  Bosnian snipers were also located throughout the city.  Not surprisingly, they were almost always in the taller buildings, which provided the best fields of fire.
