RIVERINE ASSAULT FORCE SUMMARY
December 1968
Riverine warfare in December was again characterized by interdiction, escort and patrol,
base area search and pacification operations. Small unit actions over wide areas in Kien
Hoa, Kien Giang, Choung Thien, and An Xuyen provinces accounted for 454 Viet Cong killed.
Mobile Riverine Group ALPHA operations were confined for the most part to activity in Kien
Hoa Province, and the support of the 2nd Brigade, U.S. Ninth Infantry Division. Mobile
Riverine Group BRAVO operations consisted largely of a variety of special operations in
the southern delta region in coordination with units of the 2nd, 3rd and 4th Battalions of
Vietnamese Marine Corps.
The Following table shows river assault craft employment on a typical day in December and
is indicative of the present scope of operations:

TASK GROUP 117.1 OPERATIONS
During December, Mobile Riverine Group ALPHA engaged in a series of operations (designated
Kidney Flush) designed to keep constant pressure on the Viet Cong. With frequent
insertions in Ham Long, Mo Cay and Truc Giang districts of Kien Hoa Province, Army ground
elements continued to seek out and destroy the enemy. These operations employ riverine,
air and ground assets and have produced significant attrition against the enemy. The daily
toll to the Viet Cong has been approximately 10 dead coupled with loss of supplies and
equipment. Of the many detainees taken during these actions, about 20 percent are
subsequently classified as Viet Cong, while the remainder are determined to be innocent
civilians.
Night ambush patrols have now been incorporated into the operations of the 3/60th
Infantry. This is a definite change in MRF procedures, as night landings were previously
avoided as too dangerous. The procedure being followed is to rest the troops during the
day, land them after dark, and extract them the following morning. This is the same method
successfully employed by units of the Ninth Infantry Division in Long An Province and last
month in Giong Trom District of Kien Hoa Province.
During the month RAD 92, with infantry embarked, escorted two Army supply convoys composed
of LCU's and LCM-8's from Dong Tam to the Special Forces camp at Moc Hoa. Directed from a
command and control helicopter, these convoys were heavily supported by artillery, assault
helicopter companies and embarked troops and proceeded via the Cho Gao Canal, Vam Co and
Vam Co Tay rivers. The convoys are providing support for the airfield improvement in the
Moc Hoa area.
RAD 132 with six ASPB's from RAS 9 and 11 sailed to MRG "A" on 30 November and
chopped to CTG 117.1 on 1 December. The units then joined elements of TF 116 in Operation
GIANT SLINGSHOT in the Vam Co Tay and Vam Co Dong rivers. CTG 194.0, FIRST SEA LORD,
directs the conduct of this operation.
The following hostile fire incidents are selected to briefly outline the circumstances
under which two Navymen were killed in action and seven sailors were wounded:
1. While inserting an Army intelligence gathering Long Range Reconnaissance Patrol (LRRP)
at a position 3 miles southwest of My Tho, units of RAD 91 received B-40 rocket and A/W
fire. ATC 91-8 received three B-40 rocket hits, one forward and two below the waterline.
One U.S. Army soldier was killed, eight were wounded and seven Navy crewmen were wounded.
2. On an Operation GIANT SLINGSHOT mission on 24 December, two ASPB's enroute to a
preplanned ambush site with 1st Air Cavalry elements on board, came under fire at a
position 7 miles south of Kiep Hoa on the Vam Co Dong River. During the attack, the boat
captain of A-91-5, BM2 Wallace GOING, USN, was killed. Another crewman was wounded. There
was only light damage to the ASPB's.
3. On 27 December at 2105H, a patrol in support of Operations SEA LORDS and consisting of
one ASPB, three PBR's and one ATC was proceeding south on the Rach Gia - Long Xuyen Canal
when the patrol was attacked at a position 3 miles northeast of Rach Gia. One sailor was
killed and three others were wounded as the ATC received three B-40 rocket hits. Fire was
returned as the patrol withdrew to the south. Two "Seawolf" LHFT were scrambled
and placed strikes on the suspected enemy positions.
TASK GROUP 117.2 OPERATIONS
The first five days of the month were utilized for the completion of boat maintenance in
preparation for subsequent operations.
On 5 December, RAS 15 got underway from the MRB at Can Tho with 30 assault craft for
operations in base area 480. Three companies of the 4th Battalion VNMC came aboard on 6
December and the task unit proceeded to the area to begin operations which lasted until
the 11th. Throughout the period VNMC troops conducted ground sweeps in selected locations
and the RAC patrolled in the general area within a 10 mile radius to the south and
southwest of Kien Hung and Cai Lon River. Enemy reaction to the MRF presence came in the
form of 12 B-40 rocket ambushes during the period. The fire was returned and suppressed in
all but the one instance in which there were friendly troops in the area. Two assault
craft were damaged as a result of these actions and four USN wounded. On two separate
occasions, B-40 rounds became lodged in the styrofoam of an ATC and a Zippo, and failed to
detonate. This operation proved to be one of the most successful to date and resulted in
55 Viet Cong killed. Only one friendly VNMC was killed. In addition to the large body
count, a Viet Cong prison camp was discovered by VNMC units, resulting in the release of
10 Vietnamese prisoners. Several tons of weapons, ammunition and military supplies were
captured or destroyed. The units returned to the MRB on 11 December.
The Mobile Riverine Force concept was projected into the open sea for the first time
attendant to the conduct of Operation SILVER MACE (TG 194.2) in the western end of the Cua
Lon River. Operating as units of Operation SEA LORDS, monitors, ASPB's and ATC's, with one
mobile strike force company from Binh Thuy embarked, began late on the night of 16
December and transited Phong Dinh, Chuong Thien and Kien Giang provinces and the western
coast of South Vietnam in 36 hours. Meanwhile, the USS MERCER (APB-39) with another MSF
company and a 30 man UDT/EOD element embarked, USS SATYR (ARL-23) and USS IREDELL COUNTY
(LST 839) (support/resupply LST) proceeded to the rendezvous point in the Gulf of Thailand
in three separate transits via the South China Sea and around the southern tip of Vietnam.
Rough seas delayed the commencement of the operation designed to destroy a series of 12
fish trap type barricades erected across the western end of the Cua Lon River. After
encountering difficulty on mud flats at the Cua Lon entrance, the task unit succeeded in
transiting the shallows with the aid of a VNN junk pilot. Strike forces were were
positioned on the bank and UDT/EOD units commenced destruction of the barricades. Meeting
light enemy resistance,
the SILVER MACE forces had completed barricade destruction on the morning of 22 December,
and the task unit began withdrawal from the area.
On 31 December, during reconnaissance in force operations along the Can Cao Canal in the
area 19-20 miles southwest of Rach Gia, enemy ambushes against the assault craft produced
significant friendly casualties on two occasions. While underway to land units of the 2nd
and 3rd battalions VNMC, RAC 15 craft encountered B-40 rocket and automatic weapons (A/W)
fire from both banks at 310845H. Although enemy fire was returned and suppressed, one ATC
and one monitor were damaged by rocket hits and seven USN were wounded. Later that night
between 1950H and 2045H, in the same area, the RAC, again with VNMC troops aboard, came
under attack three times and received 40 to 50 B-40 rockets and heavy A/W fire. ATC-151-12
received four B-40 hits, ATC-152-13 received one B-40 hit and ATC-151-6 sustained three
B-40 hits producing heavy casualty figures of 10 USN, 28 VNMC and 3 VNN wounded. Enemy
fire was returned by the RAC in all cases and at 2145 two "Seawolf" gunships and
USAF "Spooky" expended 21,000 rounds on the suspected enemy positions.
