The name of the offensive that even though it was an American victory changed public opinion on the war in Vietnam is "The Tet Offensive".

The Tet offensive was a military operation planned by the government of North Vietnam and executed by the North Vietnamese Army and the Vietcong in 1968, against the US-led allied forces during the Vietnam War.

The planning of the offensive was meticulous and the execution well done; but the military results were disastrous; not so the political consequences, especially in the United States. The large number of US soldiers killed during the offensive, about 14,000, was not tolerated by the American people. The rejection of the war in the United States increased and this meant a turn of the war towards the defeat of the coalition. Some authors consider that it was a tactical defeat, since in addition to the huge number of deaths among North Vietnamese fighters, they lost the totality of the conquered territories. However, it is considered to be a strategic victory due to the subsequent change that it caused in the US military strategy.
