History edit
The base was located immediately north of the Marble Mountains and south of Marble Mountain Air Facility.[2]
On the night of 22–23 August 1968, as part of their Phase III Offensive, a company from the Viet Cong (VC) R20 Battalion and a sapper platoon infiltrated the base, killing 17 Special Forces soldiers (their largest one-day loss of the war) and wounding another 125 allied soldiers. Thirty-two VC were killed.[3]
Current use edit
The base is abandoned and the area now consists of sand dunes with some commercial and residential development.
