Tet Offensive ends - Feb 22, 1968 - HISTORY.com

The American war effort in Vietnam was hit hard by the North Vietnamese Tet Offensive, which ended on this day in 1968. Claims by President Lyndon Johnson that the offensive was a complete failure were misleading. Though the North Vietnamese death toll was 20 times that of its enemies, strongholds previously thought impenetrable had been shaken. The prospect of increasing American forces added substantial strength to the anti-war movement and led to Johnson’s announcement that he would not seek re-election.
