Operation Coronado IV

Operation Coronado IV was the fourth of the Operation Coronado series of riverine military operations conducted by the U.S. Mobile Riverine Force (MRF), designed to shut down Viet Cong (VC) strongholds in the Mekong Delta.[1]:50 It ran from 19 August to 9 September 1967. It took place in Long An, Gò Công and Kiến Hòa Provinces (now Long An and Bến Tre Provinces).[1]:125

Operation

On 20 August the MRF assault craft left the Soài Rạp and Vàm Cỏ river anchorage of the MRF's main base just after midnight and landed their troops at 09:04 in the target area north of Bến Lức on the Vàm Cỏ Dong (Vam Co East) River, after travelling more than 50km. Because the waterways off the Vàm Cỏ Dong in the target area were not navigable by the vessels, the two infantry battalions were landed to move west and search the area on foot. Company C, 3rd Battalion, 47th Infantry Regiment remained at a pickup zone near the fire support base at Bến Lức as an airmobile reserve. To intercept VC forces, the 334th Aviation Company's supporting gunships maintained surveillance of the areas forward of the infantry battalions.[1]:126-7

At 14:00 the movement of the 3/47th Infantry forced a VC platoon to retreat from a lightly fortified area. The gunships were then ordered by the battalion commander to open fire on VC attempting to evade contact with the ground troops, and the 3/47th Infantry, was brought in by helicopter to attack the VC, encountering mostly sniper fire and collateral damage from US helicopter fire. The Americans found 34 VC dead and documents that identified them as part of the 506th Local Force Battalion.[1]:127

The Americans believed they had succeeded because of the surprise achieved by the ground troops in disembarking from the boats landing from the river, forcing the VC into open terrain where helicopters could attack them. During the phase of the operation at Ben Luc, which ended on 22 August, the MRF suffered six wounded and the VC 59 dead.[1]:127

For the remainder of August and the first week of September, the MRF operated in Cần Giuộc District, encountering minor communist resistance. On 7 and 8 September the force operated in conjunction with the 1st Brigade, 9th Infantry Division, in the southeastern part of Nhơn Trạch District of Biên Hòa Province and the northeastern part of the Rung Sat Special Zone. They did not encounter many VC but a cache containing medical supplies, eight crew-served weapons, and 97 small arms was discovered. As the second week of September began, the force prepared to return to Định Tường Province in IV Corps further south.[1]:127

Operation Coronado

Operation Coronado was a series of 11 operations conducted by the American Mobile Riverine Force in conjunction with various units of the Army of the Republic of Vietnam (South Vietnam) in the waterways of the Mekong Delta in the south of the country in an attempt to dismantle guerrilla forces and infrastructure of the Vietcong in the waterways of the Mekong, which had been a communist stronghold. The operations ran sequentially from June 1967 to July 1968.The series was named after Coronado Naval Base in California. There the American military had staged planning conference before adopting their riverine military strategy.

Operation Coronado II

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. 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.

Operation Coronado IX

Operation Coronado IX was a riverine military operation conducted by the Mobile Riverine Force (MRF) of the United States and elements of the Army of the Republic of Vietnam (ARVN) from November 1967 to January 1968 in an attempt to dismantle communist strongholds in the Mekong Delta. In the middle of November, clashes resulted in the capture of Viet Cong (VC) supplies and hideouts. During this period, the communists lost 178 men but killed only 26. For the next few weeks there was little contact, although some abandoned VC bunkers were destroyed and supplies captured. On 4 December, a large engagement occurred when a VC battalion encountered the South Vietnamese 5th Marine Battalion. There were 266 VC killed, mostly by the Marines. The Marines lost 40 killed, while the Americans suffered 9 dead. Over the next month and the Christmas period, there was only sproadic skirmishes, but at the start of the new year, there were some medium size battles in which the Americans killed a few dozen VC. After this there was little contact.

Operation Coronado V

Operation Coronado V was a riverine military operation conducted by the U.S. Mobile Riverine Force (MRF) and elements of the Army of the Republic of Vietnam from 12 September to 5 October 1967 in an attempt to shut down Viet Cong strongholds in the Mekong Delta. The first part of the operation took place in Định Tường Province (now Tiền Giang Province). After receiving intelligence that the Viet Cong (VC) 263rd Main Force battalion had been seen in the region, three Allied battalions were brought in on 12 September by helicopters and boats. Immediately there was heavy contact, and although the Allies reported killing 134, the majority of the VC escaped. Sweeps of the area resulted in another major confrontation with the VC on 15 September. During the four-day period, U.S. and ARVN reported 213 VC killed. The Allied forces then moved into adjoining Kiến Hòa Province (now Bến Tre Province). From 5–7 October another encounter with the VC 263rd Battalion resulted and the Allies reported 163 VC killed while losing seven.
