Operation Coronado II was the second of eleven in the Operation Coronado series conducted by the U.S. Mobile Riverine Force (MRF) in conjunction with various units of the Army of the Republic of Vietnam (ARVN) in late July 1967 in an attempt to shut down Viet Cong (VC) strongholds in the Mekong Delta.^[1]: 120 Three battalions of American troops, along with two ARVN battalions, backed by helicopters and watercraft swept the area and waterways surrounding Mỹ Tho in search of VC forces. Two VC battalions were encountered and many captured, although both sides suffered numerous casualties. The Allied forces also cordoned off the area to search water traffic for VC supplies or suspects. The Americans credited the South Vietnamese 3rd Marine Battalion for the success of the operation.
