President Lyndon B. Johnson announces that Gen. William Westmoreland will replace Gen. Paul Harkins as head of U.S. Military Assistance Command Vietnam (MACV) as of June 20. The assignment would put Westmoreland in charge of all American military forces in Vietnam. One of the war’s most controversial figures, General Westmoreland was given many honors when the fighting was going well, but when the war turned sour, many Americans saw him as a cause of U.S. problems in Vietnam. Negative feeling about Westmoreland grew particularly strong following the Tet Offensive of 1968, when he had requested a large number of additional troops for deployment to Vietnam. On March 22, 1968, President Johnson announced that Westmoreland would depart South Vietnam to take on the post of Army Chief of Staff; Gen. Creighton Abrams replaced him as the senior U.S. commander in South Vietnam.
