Firebase Fuller

Firebase Fuller (also known as Dong Ha Mountain or Hill 549) is a former U.S. Marine Corps, Army and Army of the Republic of Vietnam (ARVN) firebase in central Vietnam.

History
The base was established on Dong Ha Mountain northeast of the The Rockpile north of Highway 9.

The 3rd Battalion 9th Marines secured Fuller as part of Operation Virginia Ridge on 2 May 1969. By July the 1st Battalion 9th Marines had assumed responsibility of the area around Fuller. Elements of the 3rd Battalion, 12th Marines provided artillery support at Fuller.

In late September 1969 as part of Operation Keystone Cardinal the 3rd Marine Regiment began its withdrawal from Vietnam handing over control of Fuller to the 2nd Battalion, 4th Marines. The 4th Marines in turn handed over Fuller to elements of the 1st Brigade, 5th Infantry Division on 5 November 1969.

1971
On 22 June 1971 following an artillery barrage the PAVN launched a major attack on the ARVN base on Fuller, despite reinforcements and B-52 strikes the ARVN were pushed out of Fuller, but recaptured the base on 28 June having killed over 500 PAVN. A further PAVN attack on 1 July was repulsed.

1972
By January 1972 the ARVN 3rd Division had assumed responsibility for the area north of Highway 9. Fuller was occupied by the 1st Battalion, 2nd ARVN Regiment. From January the ARVN on Fuller together with the Vietnamese Marines on Firebase Sarge reported a buildup on PAVN forces in the surrounding area.

The PAVN launched their Easter Offensive on 30 March 1972 and PAVN artillery fire hit Fuller along with all other ARVN and Marine positions along the DMZ. Units of the PAVN 308th Division assaulted Fuller and by midday on 31 March the PAVN had overrun Fuller.
