Đông Hà Combat Base (also known as Camp Spillman, Camp Red Devil or simply Đông Hà) is a former U.S. Marine Corps and U.S. Army base northwest of Quảng Trị in central Vietnam. The base was first used by the 4th Marines in late April 1966. In mid-July Đông Hà was used by the Marines as a helicopter base and logistics area. Numerous US marine and army units rotated through the base, and several artillery units were based there.
