BATTLE OF BIEN HOA
TET OFFENSIVE 1968
Thanks to LTC Robert M Deets, Battalion Commander 1 December 1967 to
1 July 1968, for this fine detailed report on the Battle of Bien Hoa.
On the morning of 31 January 1968, the Bien Hoa Air Base, III Corps
Headquarters, the Prisoner of War Compound, and other key installations
around the Bien Hoa - Long Binh area received enemy mortar and rocket
fire. The Communists were starting to carry out a plan that they had
studied for a considerable period of time. The attacking forces, elements
of the 274th and 275th Viet Cong Regiments, along with the 68th Regiment,
9th VC Division, had been recruiting and training their leaders for a
substantial length of time. It was instilled in the minds of their
soldiers that this ultimate plan could not fail, and that victory would
surely be theirs. A prisoner later captured stated that he was told by
commanders that Bien Hoa would "drop into their hands like a ripe apple".
"Charlie" felt that such an offensive, one that involved ground attacks on
major military complexes, would be completely unexpected. He was right but
he completely underestimated the retaliatory firepower of the allied
forces, and most of all, the devastating assaults of the armed helicopter.
Approximately 1600 hours, 30 January, Lt. Col. Robert M. Deets'
secretary reported to the 145th Battalion Operations Office that her home
was taken over by the Viet Cong and was to be used for the operational
headquarters within the city of Bien Hoa.
While a silent Bien Hoa Air Base slept, Colonel Nick Psaki and LTC
Deets set up their Operational Plan Charlie - Charlie, knowing the enemy
forces would unleash a devastating attack. Beginning at 3 O'clock in the
morning of 31 January 1968, they launched their surprisingly
well-coordinated assaults at major installations throughout the
countryside. The assaults came within mimutes of each other. Throughout
Vietnam, Americans awakened to a new phase in the war. The Bien Hoa Air
Base received approximately 150 rounds of enemy rocket and mortar fire.
Almost simultaneously the Viet Cong ground forces made their move to
overrun the base. Formed into four companies of 52 men each, his soldiers
penetrated the perimeter between bunkers in the 101st Airborne Division
cantonement area and the III Corps Headquarters, gradually making their
way to the approach end of runway 27. It was there they were met by the
gunships led by Captain Kenneth Rubin, 334th Gunship Company, assigned by
the Command and Control of Checkmate Charlie-Charlie.
Captain Rubin and his "Firefly" team had just returned from a mission
near Duc Hoa when they were told to engage the enemy on the east side of
the airbase. They spotted the Viet Cong off the eastern end of the runway
and awaited clearance to fire. An emergency standby fire team from the
118th Assualt Helicopter Company was soon airborne and on station. Captain
Rubin was then given permission to engage the enemy. After approximately
30 minutes his team needed to refuel and the mission was given to the
118th Gunship Team. Captain Rubin and his Australian Co-pilot were both
wounded and their helicopter shot-up so bad it was rendered non-flyable.
Captain Rubin was given another helicopter and then formed another
"Firefly Team" and later returned for futher action. Lt. Col. Anderson and
Major Jarrett requested and were given permission to insert their Cobra
"NETT" Team into the action. Their flying was outstanding and was a major
factor in winning the Battle of Bien Hoa. Contact with the Viet Cong
lasted until late in the morning. By that time almost every helicopter
fire team in the battalion had participated in the effort to destroy the
firmly emplaced enemy in this action.
All night long personnel had received sporatic small arms fire from
the water tower near the entrance to the air base. The 12th Combat
Aviation Group Commander, Colonel Nick Psaki and elements of the 68th
Combat Aviation Company, personnally eleminated the enemy while men on the
ground observed the battle only 100 meters away. By noon the tower was
under control and the enemy guerillas were dead, but they were hard to
beat in their well-fortified positions.
III Corps Headquarters, adjacent to the air base came under mortar
attack at 0545 hours. By 0700 hours the VC had begun to move from his
vulnerable position off the end of the runway to the buildings across the
street from the headquarters. The occupants of the compound received
automatic weapons and RPG rocket fire from the new enemy emplacements.
Gunships and armored vehicles from the 11th Armored Cavalry Regiment
engaged the enemy forces in house to house fighting and drove them from
The Viet Cong casualties were extremely heavy during this encounter.
Elements of the 145th Combat Aviation Battalion supported other
hard-hit installations during the widespread Tet Truce Offensive. At the
same time Bien Hoa Air Base received its first incoming rounds, the nearby
Long Binh Complex, Headquarters II Field Force, received rocket mortar
fire. Elements of the 274th and 275th Viet Cong Regiments launched a heavy
ground attack around that area. Twenty-four hours earlier the most
elaborate military headquarters in Vietnam had enjoyed an uneventful duty
day, but suddenly it was fighting for its life. Attacking from across
highway 1A from Khu Gia Vien Village, commonly known as "windows village,"
the heavily armed enemy assaulted the devensive perimeter. The "Mustang"
fire teams from the 68th Assault Helicopter Company, and "Striker" AH-1G
"Cobra" helicopters from the NETT Team proceeded immediately to the area
to give fire support to the embattled friendly forces. Continuous air
assaults were provided by these ships to repel the enemy attacks. It was
later learned that beneath "Widows Village", "Charlie" had built an
elaborate tunnel complex, complete with ammunition and supplies, making
himself well prepared for an assault on the 12th CAG and the Long Binh
The Viet Cong also launched a major effort in the Saigon-Cholon area.
The "Bandits", gunships of the 118th Assault Helicopter Company launched
combat assaults against Viet Cong firmly emplaced in the Phu Tho Race
Track. Elements of the 68th Assault Helicopter Company were in heavy
contact with enemy forces occupying the Cholon district of Saigon. Cobra
aircraft from the 334th Armed Helicopter Company and Cobra NETT Team were
also dispatched to Saigon to add their devastating firepower on the enemy.
Helicopters of the 190th Assault Helicopter Company were called upon to
evacuate the besieged defenders of the American Embassy, who were hard hit
by the daring enemy.
Since the American New Year, there had been strong indications the
enemy was planning such a major offensive. Since January 20th United
States military along with our own Vietnamese intelligence sources had
suspected the enemy's intentions. The 274th and 275th Viet Cong Regiments
were located as far north as Bu Dop in early January. Their north to south
cross-country movement placed them in the vicinity of the Dong Nai River
by the end of the month. The 68th Regiment of the 9th Viet Cong Division
moved from a position near Tay Ninh in early January to Bien Hoa in time
for the attack on January 31. As early as the 2nd of December, a warning
order had been given to the residents of Bien Hoa City that they had
better stop cooperating with the U.S. Forces or face annihilation. At
seven o'clock in the evening of 30 January 1968, seven Viet Cong rode by
the main gate of the 145th Combat Aviation Battalion and shouted,
"Yankee--tonight you die". These VC were armed with pistols, automatic
weapons, and one grenade launcher.
Minutes before the first rocket round impacted on the air base the
enemy forces had penetrated the perimeter and were poised for the attack.
The attacks of the Viet Cong caught almost everyone by surprise except
Colonel Psaki and Lt. Col. Deets. Those who were accustomed to the
unimpeded everyday routine of "rear area" living suddenly found themselves
thrust into action against a determined enemy force. In place of an
uneventful night's rest, the American and Allied Force on the air base
were shaken from their beds by the blinding flash and deafening explosion
of impacting Chinese Communist 122mm rockets. Suddenly the Bien Hoa Air
Base wasn't secure as it was thought to be. Immediately following the
initial rocket attack the sky was lined with tracers and one was faced
with the stark realization that this was no ordinary mortar attack. The
action seemed painfully close, and immediate reaction to the harrowing
enemy threat was paramount. Crew Chiefs quickly readied their aircraft for
action. Maintenance personnel prepared themselves to keep all aircraft
flyable. Aircraft commanders gave last minute briefings to their crews
and were soon airborne in an all-out effort to repulse the Communist
intruders. In order to continue to give the ground commander the maximum
effort he had learned to expect from the 145th, all personnel worked
longer hours under more strenuous conditions; "Charlies" presence was
keenly felt. Maintenance personnel worked virtually around the clock in
order to put damaged aircraft back in flying conditions. Ground crews
refueled and reloaded their helicopters in record time. Company clerks and
cooks learned how to be door gunners, and basic infantry training was put
to use. For the first time in many months there was no mail, it was
backlogged in Ton Son
Nhut Air Base or stacked up in San Francisco. Everybody became accustomed
to "C" rations, and meals in the mess halls were few.
The effort put forth by the members of the 145th Combat Aviation
Battalion resulted in the successful defense Bien Hoa, while Air Force
fighter aircraft were initially forced to remain on the ground, Army
helicopters were quickly aloft and defending the perimeter of the air
base. The men of the 145th Combat Aviation Battalion kept the enemy in
place until the job was done.

Battle of Bien Hoa, Audio Cassette Tape
We have audio cassette tapes of the Battle of Bien Hoa as reported by
Air Force Master Sergeant Jack Thompson at dawn on the morning of 31
January 1968 from the top of a building next to the Air Force runway. It
is a audio record of the 145th CAB helicopters battling the Viet Cong on
the Air Force runways and on the perimeter. On the tape you can hear all
the sounds of the battle, the gunships rolling in, the mini-guns firing,
2.75 rockets impacting, incoming 122mm rockets exploding, fuel and ammo
dumps blowing up, as M.Sgt Jack Thompson describes the action. Its really
a great asset to supplement our battalion history report of the Battle of
Bien Hoa. They sell for $15 each and as an extra value the other side of
the tape contains a recording made from a gunship from the 190th AHC, we
call this side of the tape "Gunship Action". Fundraisers like this one
help fund our Association and make it possible to keep locating more
people. So please, if you can, order one of the tapes, order form on back
339th TRANSPORTATION COMPANY
I just found out about the 339th Transportation Company. The 339th
arrived in Vietnam on the 7th of February, 1962 to provide maintenance
support to the Aviation units. When the 45th Transportation Battalion
arrived in Vietnam the 339th became part of it and stayed with the 45th /
145th for many years. It will now be listed as one of our unit in all
future ads to locate new people. Hopefully soon we will have many people
located from the 339th Transportation Company.
I want to say Welcome to the 45th / 145th Association to all the
former members of the 339th. And thank you to Bryce Whitson for the
information about the 339th, he served with the 339th in Vietnam from
February 1962 til February 1963. He has many interesting stories to tell
from that time period. I hope to see him and everyone else at our next
