Final answer:
The fierce fighting in Hue during 1968 was part of the Tet Offensive, the turning point of the Vietnam War which led to a shift in U.S. public opinion and contributed to increased anti-war sentiment.
Step-by-step explanation:
In 1968, fighting was fierce in Hue during the Tet Offensive, which is considered the turning point of the Vietnam War. The Tet Offensive was a significant event where North Vietnamese and Viet Cong forces launched widespread surprise attacks across South Vietnam, including Hue and the capital, Saigon. Despite the high casualties suffered by the attackers, the scale and intensity of the offensive shattered American public confidence in the war effort and led to increased calls for troop withdrawal. The Tet Offensive exposed the Johnson administration's overly optimistic portrayal of the war situation and significantly affected U.S. public opinion and policy regarding the war effort.
