Operation Starlite  Operation Starlite (also known in Vietnam as Battle of Van Tuong) was the first major offensive action conducted by a purely U.S. military unit during the Vietnam War from 18 to 24 August 1965. The operation was launched based on intelligence provided by Major general Nguyen Chanh Thi, the Army of the Republic of Vietnam (ARVN) I Corps commander. III Marine Amphibious Force (III MAF) commander Lieutenant General Lewis W. Walt devised a plan to launch a pre-emptive strike against the Viet Cong (VC) 1st Regiment to nullify their threat to the vital Chu Lai Air Base and Base Area and ensure its powerful communication tower remained intact. The operation was conducted as a combined arms assault involving ground, air and naval units. U.S. Marines were deployed by helicopter insertion while an amphibious landing was used to deploy other Marines. The VC used a variety of tactics to counter the Marine assault, fighting from prepared positions and then withdrawing as the Marines gained local superiority and ambushing a lost supply column. The VC were unable to withstand the weight of the Marine assault and U.S. firepower losing 614 killed and nine captured for U.S. losses of 42 killed. The United States had been providing material support to South Vietnam since its foundation in 1954. The Vietnam War effectively began with the start of the North Vietnamese backed VC insurgency in 1959/60 and the U.S. increased its military aid and advisory support to South Vietnam in response. With the worsening military and political situation in South Vietnam, the U.S. increasingly became directly involved in the conflict. U.S. Marines were the first ground troops deployed to South Vietnam, landing at Da Nang on 8 March 1965. In May the Marines and ARVN forces secured the Chu Lai area to establish a jet-capable airfield and base area. On 30 July, COMUSMACV General William Westmoreland told III MAF commander General Walt that he expected him to undertake larger offensive operations with the South Vietnamese against the VC at greater distances from his base areas. Walt reminded Westmoreland that the Marines were still bound by the 6 May Letter of Instruction that restricted III MAF to reserve/reaction missions in support of South Vietnamese units heavily engaged with a VC force. Westmoreland replied "these restraints were no longer realistic, and invited Walt to rewrite the instructions, working into them the authority he thought he needed, and promised his approval." On 6 August, General Walt received official permission to take the offensive against the VC.
