January 30
Tet Offensive Begins in South Vietnam
Summary
During the Vietnam War, North Vietnamese leaders coordinated a massive surprise assault timed with the Tet lunar new year holiday to weaken allied forces and incite popular uprisings. Initial attacks struck targets in northern provinces on the early morning of January 30, 1968, with the broader offensive following the next day across more than 100 cities, towns, and military bases. U.S. and South Vietnamese troops repelled most assaults after intense fighting, notably in Saigon and Hue, but suffered significant losses. The coordinated communist campaign involved around 85,000 troops despite holiday leave for many South Vietnamese soldiers.
Why It Matters
Although a military setback for the attackers, the offensive dramatically shifted U.S. public opinion and media coverage against the war, accelerating de-escalation policies. It remains a landmark example of how battlefield events can reshape political will in prolonged conflicts.
