On this day, weekly casualty figures are released that contain no U.S. fatalities for the first time since March 1965. There were several reasons for this. President Nixon’s troop withdrawal program, first initiated in the fall of 1969, had continued unabated even through the height of the fighting during the 1972 North Vietnamese “Easter Offensive.” By this time in the war, there were less than 40,000 U.S. troops left in South Vietnam. Of this total, only a small number, mostly advisors, were involved in ground combat. In addition, it appeared that the North Vietnamese offensive, which had been blunted by the South Vietnamese with the aid of massive U.S. airpower, was finally winding down; there had been a general lull in ground fighting for the sixth straight day. South Vietnamese losses continued to be high since they had assumed the responsibility for fighting the ground battle in the absence of U.S. combat troops.
