History

In the First Indochina War, two battalions of the French forces were wiped out on Hill 55.[3]

In early 1966, Hill 55 was the dominant terrain feature in the area of responsibility of the 9th Marine Regiment. It had to be occupied to allow the Marines to continue operations against the Viet Cong. The hill was secured in late January, 1966. The hill had been extensively mined by the VC, necessitating a mine clearing operation by tracked vehicles of the 1st Amphibian Tractor Battalion. Engineers from the 3rd Combat Engineer Battalion constructed a command post. Most of this clearing work was completed by the end of February, 1966.[1] On March 29, engineers began construction of a regimental command post for the 9th Marines.[1]: 80 

The base was named Camp Muir after Marine Lieutenant Colonel Joseph Muir, commanding officer of the 3rd Battalion, 3rd Marines who was killed on the hill by a booby-trap on 11 September 1965.[2]

In September 1966 the Marines created an Assault Fire Unit consisting of 15 HAWK antiaircraft missiles from the 1st Light Antiaircraft Missile Battalion which deployed to Hill 55. The HAWK air defense was a mobile, surface-to-air guided missile system designed to defend the Da Nang Air Base against attack by North Vietnamese aircraft.[1]: 270 

Marine Captain Edward James Land started a Scout/Sniper school on the hill in 1966.[4] Notable Marine sniper Carlos Hathcock was stationed with the 1st Marine Division Scout Sniper Platoon on Hill 55.[5]

By the beginning of 1968, control of Hill 55 had passed to the 7th Marine Regiment.[6]: 97  On January 31, 1968, during the Tet Offensive, Communist troops bombarded Hill 55 with mortars. Marine casualties were light.[6]: 155  During the night of 5–6 February, enemy gunners fired 122mm rockets at the base, resulting in little damage.[6]: 159 

In August 1969, the 26th Marine Regiment established their command post at Camp Muir, replacing the 7th Marines.[7]: 188  In July 1969, the antiaircraft missile unit with its HAWK missiles ceased operations in preparation for redeployment to Camp Pendleton, California.[7]: 241  Marine artillery at Hill 55 in 1969 included batteries from 4th Battalion, 11th Marines. The 1st Battalion, 11th Marines had its command post on the hill.[7]: 243 

1970 began a period of redeployment for U. S. Marines from South Vietnam. In early 1970, the 1st Marine Regiment was in control of the area around Hill 55. In March 1970, the 1st Marines transferred responsibility for the security of Hill 55 to the Army of the Republic of Vietnam (ARVN) 51st Regiment.[8]: 37, 180  Combat operations by Marine, U.S. Army, ARVN, and South Korean soldiers against Communist forces in the area continued into 1971.[8]: 118–35
