The inauguration of Richard Nixon in January led to a reevaluation of the U.S. role in the war. U.S. forces peaked at 543,000 in April. U.S. military strategy remained relatively unchanged from the offensive strategy of 1968 until the Battle of Hamburger Hill in May which led to a change a more reactive approach. The U.S. and South Vietnam agreed on a policy of Vietnamization with South Vietnamese forces being expanded and equipped to take over more of the ground combat from the departing Americans which began to withdraw in late June without any reciprocal commitment by the North Vietnamese. The morale of U.S. ground forces began to fray with increasing racial tensions and the first instances of fragging and combat refusal.
