Context: In 1966 Haig took command of a battalion of the 1st Infantry Division in Vietnam. On May 22, 1967, Lieutenant Colonel Haig was awarded the Distinguished Service Cross, the U.S. Army's second highest medal for valor, by General William Westmoreland as a result of his actions during the Battle of Ap Gu in March 1967. During the battle, Haig's troops (of the 1st Battalion, 26th Infantry, 1st Infantry Division) became pinned down by a Viet Cong force that outnumbered U.S. forces by three to one. In an attempt to survey the battlefield, Haig boarded a helicopter and flew to the point of contact. His helicopter was subsequently shot down. Two days of bloody hand-to-hand combat ensued. An excerpt from Haig's official Army citation follows:  When two of his companies were engaged by a large hostile force, Colonel Haig landed amid a hail of fire, personally took charge of the units, called for artillery and air fire support and succeeded in soundly defeating the insurgent force ... the next day a barrage of 400 rounds was fired by the Viet Cong, but it was ineffective because of the warning and preparations by Colonel Haig. As the barrage subsided, a force three times larger than his began a series of human wave assaults on the camp. Heedless of the danger himself, Colonel Haig repeatedly braved intense hostile fire to survey the battlefield. His personal courage and determination, and his skillful employment of every defense and support tactic possible, inspired his men to fight with previously unimagined power. Although his force was outnumbered three to one, Colonel Haig succeeded in inflicting 592 casualties on the Viet Cong ... HQ US Army, Vietnam, General Orders No. 2318 (May 22, 1967)  Haig was also awarded the Distinguished Flying Cross and the Purple Heart during his tour in Vietnam and was eventually promoted to colonel, becoming a brigade commander in the 1st Infantry Division in Vietnam.
