The Vietnam remembrance "We Were Soldiers Once ...and Young" was coauthored by Lieutenant General Harold G. Moore, USA ( Ret.), and Joseph L. Galloway. It recounts four days of incredibly intense and desperate combat between the U.S. Army's 1st Cavalry Division (Airmobile) and three regiments of North Vietnamese infantry in the Ia Drang Valley of Pleiku Province in November 1965. Then-Lieutenant Colonel Hal Moore commanded the 1st Battalion of the 7th Cavalry, whose saga is recalled in the first part of the book, and the movie. Elements of several other cavalry regiments were also involved. All told, during a four-day period, 234 young Americans lost their lives in the action. But together, the two battalions killed perhaps ten times as many of the enemy.
