The Tet holiday in Vietnam is a joyous celebration to ring in the lunar new year and springtime with big family reunions and feasting.

However, it is also remembered for a very significant military engagement of the American-Vietnam War.

The Tet Offensive in 1968 was one of the nation’s largest military campaigns. Fought in hundreds of towns and villages, it left thousands in the South Vietnam capital of Saigon dead and hundreds of homes destroyed.

This series of surprise attacks by the Communist North Vietnamese forces happened during the Tet festivities and still shakes some residents of Saigon, or what is now known as Ho Chi Minh City.
