Đồng Tâm Base Camp was established on the banks of the Mekong 7 km west of Mỹ Tho upon the U.S. Commander in South Vietnam General William Westmoreland's decision to gain full control over the Upper Mekong Delta Region and he personally took part in site selection.[1] The name Đồng Tâm meaning "united hearts and minds" or "singleness of mind, in thoughts, and actions" in Vietnamese was also chosen by Westmoreland.[2] The total construction price for the Army and Navy ran close to $8,000,000.[1]

Due to lack of available dry land, the base was created by dredging from the river.[3] Dredging work to create the base commenced in August 1966 and involved the reclamation of 600 acres of swampland.[2] The Vietcong attempted to sabotage the base construction sinking the dredgeship Jamaica Bay on 9 January 1967 with the loss of 3 crewmembers.[2]:189 In January 1967 the 3rd Battalion, 60th Infantry was deployed to Đồng Tâm to provide base and construction security followed in March by Headquarters, 2nd Brigade, 9th Infantry Division which moved from Bearcat Base. In April the US Navy River Assault Squadron 9 was deployed to Đồng Tâm to support operations.[2]:189

On 1 June 1967, the Mobile Riverine Force (MRF) comprising the 2nd Brigade, 9th Infantry Division and the US Navy River Assault Squadrons 9 and 11 was established at Đồng Tâm. By this time the base occupied 12 square kilometres and included a 500m runway and a loading basin for boats.[2]:190[4]

From June–December 1967 base facilities grew providing improved support and rest and recreation for the MRF. The Vietcong regularly harassed the base with mortar fire.[2]:190

Other units stationed at Đồng Tâm included:


On 1 September 1969 Đồng Tâm was turned over to the ARVN 7th Division which moved its headquarters there from Mỹ Tho.[5]

When President Dương Văn Minh announced the unconditional surrender of South Vietnam on 30 April 1975, ARVN Brigadier General Trần Văn Hai committed suicide at the base

Current useEdit

The base was abandoned and turned over to farmland and housing while the harbour area is used for fishing and transport vessels. Harbor area as of Tet of 2018 is government controlled and leases facilities for civilian marine construction purposes. Access to this area requires government approval.
