Ngô Quang Trưởng was an officer in the Army of the Republic of Vietnam (ARVN). Trưởng gained his commission in the Vietnamese National Army in 1954 and moved up the ranks over the next decade, mostly in the Airborne Brigade. In 1966, Trưởng commanded a division for the first time after he was given command of the 1st Division after helping to quell the Buddhist Uprising. He rebuilt the unit after this divisive period and used it to reclaim the city of Huế after weeks of bitter street fighting during the Tết Offensive.

The Tet Offensive was a major escalation and one of the largest military campaigns of the Vietnam War. The Viet Cong (VC) and North Vietnamese People's Army of Vietnam (PAVN) launched a surprise attack on January 30, 1968 against the forces of the South Vietnamese Army of the Republic of Vietnam (ARVN), the United States Armed Forces and their allies. It was a campaign of surprise attacks against military and civilian command and control centers throughout South Vietnam. The name is the truncated version of the Lunar New Year festival name in Vietnamese, Tết Nguyên Đán, with the offense chosen during a holiday period as most ARVN personnel were on leave. The purpose of the wide-scale offensive by the Hanoi Politburo was to trigger political instability in a belief that mass armed assault on urban centers would trigger defections and rebellions.
