Leading up to the 1968 Tet Offensive, the Pentagon tried to convince the American public that it was winning the war.
General Bruce Palmer, Jr., one of Westmoreland's three Field Force commanders, claimed that "the Viet Cong has been defeated" and that "He can't get food and he can't recruit. He has been forced to change his strategy from trying to control the people on the coast to trying to survive in the mountains."
