Description: The Mobile Riverine Force, 9th Inf Div supported by the 5/60th Mech Inf and D/3/5 CAV plus elements from the 7th ARVN Div, 44th ARVN Rangers conducted this search and destroy operation to help provide security for the Dong Tam Base Camp. The opertion claimed 73 enemy KIAs and 68 POWs while the US suffered 9 KIAs and 64 WIAs. Called Dinh Tuong Operation (but not CORONADO II) in Riverine Operations, the MRF joined the largest force with which it would co-operate in a single operation during its tour. Reacting to intelligence that several VC battalions would soon threaten My Tho and Dong Tam, this operation was a simultaneous attack on three of the four VC base areas in Dinh Thuong Province. The U.S. 9th Inf Div established a forward CP at Dong Tam to facilitate command and control for this operation. On 27 July, the elements of the 7th ARVN Div with the 44th ARVN Rangers initiated operations north of Highway 4 around the Ap Bac base area and eastern portion of base area 470. On 28 July, the MRF moved against the Cam Song base area south of Cai Lay. The 5/60 Mech moved from Cai Lay and the two MRF bns from the My Tho river. The 1st (source also says 2d) Brigade, 25th Inf relocated to Dong Tam on the 28th and would be inserted on the 31st into the Ban Long base area. On 29 July, elements of the Vietnamese Marine Corps moved into the Ban Long base area. The 3d Bn, VMC would do the majority of the fighting in this operation and performed very well against the VC. U.S. Navy TF 116 (GAME WARDEN) patrolled the My Tho river from My Tho to Sa Dec with 30 river patrol boats.
