On January 30, 1968, communist-affiliated troops from North Vietnam and the Viet Cong (a distinct political organization) launched the so-called Tet Offensive against South Vietnam and their United States allies. The Tet Offensive was the largest military operation of the Vietnam War to that point, and would emerge as a key turning point in the conflict.
 
The Tet Offensive was a surprise series of attacks launched during Tet, the Vietnamese New Year festival. Many South Vietnamese troops were given a traditional weeklong holiday during Tet, and the military was completely unprepared for the assault. The 10-month engagement targeted more than 100 cities and towns, including the strategic southern capital of Saigon.
 
The Tet Offensive was a catastrophic military failure for the communists. As many as 50,000 troops died in the effort to gain control of the southern part of the country. The South Vietnamese and American losses totaled about 10,000.
 
Although a military loss, the Tet Offensive was a stunning propaganda victory for the communists. In fact, it is often credited with turning the war in their favor. The South Vietnamese lost morale as Viet Cong guerrillas infiltrated rural areas formerly held by the government. South Vietnamese leaders also began to suspect their U.S. allies withheld knowledge of the Tet Offensive.
 
The consequences of the Tet Offensive extended to the United States. Many Americans began to question military and political leaders who assured them the Vietnam War would be won soon. In the wake of the Tet Offensive, popular journalist Walter Cronkite remarked that “we are mired in a stalemate” where “the only rational way out, then, will be to negotiate, not as victors, but as an honorable people who lived up to their pledge to defend democracy and did the best they could.”
