Sixty years ago today, June 29, 1965 (June 1, 1965 in the lunar calendar), the US military fought in Vietnam for the first time. Americans pass through a beachhead position before entering the deserted jungle On the night of June 29, 1965, American troops followed forces from the Saigon government to conduct their first combat mission in Vietnam. This battle is a sweep. The target was Area D, a Communist stronghold 20 miles northeast of Saigon. Vietcong mortar fire killed at least one U.S. soldier. Since the end of the War against France, the Communist Party has penetrated deep into Area D, deep in the jungle. South Vietnamese troops have not entered this area in 20 years. In another clash with Communist guerrillas south of Da Nang, four U.S. Marines were killed and several others were injured. In early June, the U.S. State Department revealed that President Johnson authorized U.S. troops to participate in a larger war in South Vietnam. General Westmoreland, commander of the U.S. military in South Vietnam, has been given the authority to send troops to war if the Saigon government requests assistance. Before the beginning of this month, Americans were only allowed to provide "circular defense" to various facilities. Everyone knew that they risked pursuing Communist troops far beyond the perimeter of the defense. Classic comment: Since then, the United States has been unable to allocate it in the Vietnam War.
