"Fighting 69th"

The history of the 1st Battalion, 69th Infantry Regiment, stretches back to the Revolutionary War, and includes service during the War of 1812 and the American Civil War, where it formed the nucleus around which the Irish Brigade was formed and fought in action as part of the Army of the Potomac from the First Bull Run through the surrender at Appomattox.

The 69th also took part in the Spanish-American War, the Mexican Border campaign, World War I, to include the Meuse-Argonne campaign and World War II, where it served in the Pacific theatre at Makin, Saipan and Okinawa.

Two companies totalling 200 soldiers, Companies A and B, of the 1st Battalion, 69th Infantry Regiment were federalized in November 2001 and assigned to West Point for a six-month period to help the academy with its security in the aftermath of the attacks of September 11, 2001. They arrived at West Point on November 14, following a two-week period of training at Fort Dix, NJ, and were tasked with helping augment the U.S. Military Academy's Military Police in providing force protection, security and training.
