With the beginning of the North Vietnamese Tet Offensive on January 30, 1968, the Vietnamese lunar New Year, large conventional American forces had been committed to combat upon Vietnamese soil for almost three years. Passing through the city of Huế, Highway 1 was an important supply line for ARVN, US, and Allied Forces from the coastal city of Đà Nẵng to the Vietnamese Demilitarized Zone. It also provided access to the Perfume River at the point where the river ran through Huế, dividing the city into northern and southern parts. Huế was also a base for United States Navy supply boats. Considering its logistical value and its proximity to the DMZ, Huế should have been well-defended, fortified, and prepared for any communist attack. However, the city had few fortifications and was poorly defended. While the ARVN 1st Division had cancelled all Tet leave and was attempting to recall its troops, the South Vietnamese and U.S. forces in the city were unprepared when the Viet Cong and the PAVN launched the Tet Offensive, attacking hundreds of military targets and population centers across the country, including Huế. The PAVN/Vietcong forces rapidly occupied most of the city. Over the next month, they were gradually driven out during intense house-to-house fighting led by the Marines and ARVN. In the end, although the Allies declared a military victory, the city of Huế was virtually destroyed, and more than 5,000 civilians were killed (2,800 of them executed by the PAVN and Viet Cong, according to the South Vietnamese government). The communist forces lost an estimated 2,400 to 8,000 killed, while Allied forces lost 668 dead and 3,707 wounded. The losses negatively affected the American public's perception of the war, and political support for the war began to wane.
