SYNOPSIS: When U.S. troops were pulled out of Southeast Asia in early 1975,
Vietnamese communist troops began capturing one city after another, with
Hue, Da Nang and Ban Me Thuot in March, Xuan Loc in April, and finally on
April 30, Saigon. In Cambodia, communist Khmer Rouge had captured the
capital city of Phnom Penh on April 17. The last Americans were evacuated
from Saigon during "Option IV", with U.S. Ambassador Martin departing on
April 29. The war, according to President Ford, "was finished."

2Lt. Richard Van de Geer, assigned to the 21st Special Ops Squadron at NKP,
had participated in the evacuation of Saigon, where helicopter pilots were
required to fly from the decks of the 7th Fleet carriers stationed some 500
miles offshore, fly over armed enemy-held territory, collect American and
allied personnel and return to the carriers via the same hazardous route,
heavily loaded with passengers. Van de Geer wrote to a friend, "We pulled
out close to 2,000 people. We couldn't pull out any more because it was
beyond human endurance to go any more..."

At 11:21 a.m. on May 12, the U.S. merchant ship MAYAGUEZ was seized by the
Khmer Rouge in the Gulf of Siam about 60 miles from the Cambodian coastline
and eight miles from Poulo Wai island. The ship, owned by Sea-Land
Corporation, was en route to Sattahip, Thailand from Hong Kong, carrying a
non-arms cargo for military bases in Thailand.

Capt. Charles T. Miller, a veteran of more than 40 years at sea, was on the
bridge. He had steered the ship within the boundaries of international
waters, but the Cambodians had recently claimed territorial waters 90 miles
from the coast of Cambodia. The thirty-nine seamen aboard were taken

President Ford ordered the aircraft carrier USS CORAL SEA, the guided
missile destroyer USS HENRY B. WILSON and the USS HOLT to the area of
seizure. By night, a U.S. reconnaissance aircraft located the MAYAGUEZ at
anchor off Poulo WaI island. Plans were made to rescue the crew.  A
battalion landing team of 1,100 Marines was ordered flown from bases in
Okinawa and the Philippines to assemblE at Utapao, Thailand in preparation
for the assault.

The first casualties of the effort to free the MAYAGUEZ are recorded on May
13 when a helicopter carrying Air Force security team personnel crashed en
route to Utapao, killing all 23 aboard.

Early in the morning of May 13, the Mayaguez was ordered to head for Koh
Tang island. Its crew was loaded aboard a Thai fishing boat and taken first
to Koh Tang, then to the mainland city of Kompong Song, then to Rong San Lem
island. U.S. intelligence had observed a cove with considerable activity on
the island of Koh Tang, a small five-mile long island about 35 miles off the
coast of Cambodia southwest of the city of Sihanoukville (Kampong Saom), and
believed that some of the crew might be held there. They also knew of the
Thai fishing boat, and had observed what appeared to be caucasians aboard
it, but it could not be determined if some or all of the crew was aboard.

The USS HOLT was ordered to seize and secure the MAYAGUEZ, still anchored
off Koh Tang. Marines were to land on the island and rescue any of the crew.
Navy jets from the USS CORAL SEA were to make four strikes on military
installments on the Cambodian mainland.

On May 15, the first wave of 179 Marines headed for the island aboard eight
Air Force "Jolly Green Giant" helicopters. Three Air Force helicopters
unloaded Marines from the 1st Battalion, 4th Marines onto the landing pad of
the USS HOLT and then headed back to Utapao to pick up the second wave of
Marines. Planes dropped tear gas on the MAYAGUEZ, and the USS HOLT pulled up
along side the vessel and the Marines stormed aboard. The MAYAGUEZ was

Simultaneously, the Marines of the 2/9 were making their landings on two
other areas of the island. The eastern landing zone was on the cove side
where the Cambodian compound was located. The western landing zone was a
narrow spit of beach about 500 feet behind the compound on the other side of
the island. The Marines hoped to surround the compound.

As the first troops began to unload on both beaches, the Cambodians opened
fire. On the western beach, one helicopter was hit and flew off crippled, to
ditch in the ocean about 1 mile away. The pilot had just disembarked his
passengers, and he was rescued at sea.

Meanwhile, the eastern landing zone had become a disaster. The first two
helicopters landing were met by enemy fire. Ground commander, (now) Col.
Randall W. Austin had been told to expect between 20 and 40 Khmer Rouge
soldiers on the island. Instead, between 150 and 200 were encountered.
First, Lt. John Shramm's helicopter tore apart and crashed into the surf
after the rotor system was hit. All aboard made a dash for the tree line on
the beach.

One CH53A helicopter was flown by U.S. Air Force Major Howard Corson and
2Lt. Richard Van de Geer and carrying 23 U.S. Marines and 2 U.S. Navy
corpsmen, all from the 2nd Battalion, 9th Marines. As the helicopter
approached the island, it was caught in a cross fire and hit by a rocket.
The severely damaged helicopter crashed into the sea just off the coast of
the island and exploded. To avoid enemy fire, survivors were forced to swim
out to sea for rescue. Twelve aboard, including Maj. Corson, were rescued.
Those missing from the helicopter were 2Lt. Richard Van de Geer, PFC Daniel
A. Benedett, PFC Lynn Blessing, PFC Walter Boyd, Lcpl. Gregory S.
Copenhaver, Lcpl. Andres Garcia, PFC James J. Jacques, PFC James R. Maxwell,
PFC Richard W. Rivenburgh, PFC Antonio R. Sandoval, PFC Kelton R. Turner,
all U.S. Marines. Also missing were HM1 Bernard Gause, Jr. and HM Ronald J.
Manning, the two corpsmen.

Other helicopters were more successful in landing their passengers. One
CH53A, however was not. SSgt. Elwood E. Rumbaugh's aircraft was near the
coastline when it was shot down. Rumbaugh is the only missing man from the
aircraft. The passengers were safely extracted. (It is not known whether the
passengers went down with the aircraft or whether they were rescued from the

By midmorning, when the Cambodians on the mainland began receiving reports
of the assault, they ordered the crew of the MAYAGUEZ on a Thai boat, and
then left. The MAYAGUEZ crew was recovered by the USS WILSON before the
second wave of Marines was deployed, but the second wave was ordered to
attack anyway.

Late in the afternoon, the assault force had consolidated its position on
the western landing zone and the eastern landing zone was evacuated at 6:00
p.m. By the end of the 14-hour operation, most of the Marines were extracted
from the island safely, with 50 wounded. Lcpl. Ashton Loney had been killed
by enemy fire, but his body could not be recovered.

Protecting the perimeter during the final evacuation was the machine gun
squad of PFC Gary L. Hall, Lcpl. Joseph N. Hargrove and Pvt. Danny G.
Marshall. They had run out of ammunition and were ordered to evacuate on the
last helicopter. It was their last contact. Maj. McNemar and Maj. James H.
Davis made a final sweep of the beach before boarding the helicopter and
were unable to locate them. They were declared Missing in Action.

The eighteen men missing from the MAYAGUEZ incident are listed among the
missing from the Vietnam war. Although authorities believe that there are
perhaps hundreds of American prisoners still alive in Southeast Asia from
the war, most are pessimistic about the fates of those captured by the Khmer

In 1988, the communist government of Kampuchea (Cambodia) announced that it
wished to return the remains of several dozen Americans to the United
States. (In fact, the number was higher than the official number of
Americans missing in Cambodia.) Because the U.S. does not officially
recognize the Cambodian government, it has refused to respond directly to
the Cambodians regarding the remains. Cambodia, wishing a direct
acknowledgment from the U.S. Government, still holds the remains.

Inadvertently Left Behind -   Within the next several months, the Defense
Department will announce the remains identification of servicemen lost  on
May 15th 1975, at the Kho Tang Island, Cambodia.  Eighteen airman, sailors
and marines were lost during an attempt to free the U.S. merchant vessel
Mayaguez.  A detailed article by Lisa Hoffman of Scirpps Howard News Service
, published in the Washington Times, on February 23rd 2000 details incident
and the evidence that three men were inadvertently left behind... alive.

"...absent is a final accounting of the fate of three Marines who
inadvertently were left behind on the island when the rest evacuated.  They
are believed to have been captured and executed days later."

"The tragic story of the Kho Tang battle began with the seizure of the
Mayaguez off the southern coast of Cambodia, 12 days after the  fall of
South Vietnam's capital, Saigon. President Ford ordered U.S. forces to
rescue the 39 crew members."

"By the time the Marines launched their assault, the Cambodians had released
the Mayaguez sailors on the Cambodian mainland. An  intelligence failure
left the Marines unaware that their services no longer were needed."

"More than 230 Marines stormed ashore on Kho Tang, expecting an easy job of
overcoming a small enemy encampment numbering no more  than 20. Instead,
they were met by a well-armed force of 150. A furious battle lasted three
hours. Among the losses was the CH-53A  helicopter, on which 13 GIs died. In
all, 18 U.S. troops were killed.

"The Marines drew back and waited 15 hours to be evacuated from the island,
in what became one of the most dramatic rescues of the war. A  three-man
machine gun team, which included Covington, Ky., native Gary Hall, was
dispatched to protect the troops' flank during the  withdrawal. But in the
fog of battle, the team was mistakenly overlooked. It wasn't until the next
day that their absence was  realized. By then, it was too late to go back."

"Although their fate is not entirely certain, it is believed the trio
survived for several days before being captured and killed. One  reportedly
was shot to death after being caught stealing food from the Khmer Rouge camp
. The other two apparently were bludgeoned to  death."

"It wasn't until 1992 that military investigators with the Pentagon's Joint
Task Force-Full Accounting operation, which is in  charge of accounting for
U.S. MIAs, were able to explore either the island or the helicopter wreckage
just offshore."

"By 1995, the team - which faced obstacles ranging from unexploded ordnance,
poisonous snakes, fierce storms and tropical diseases - had come up with an
elaborate method of essentially salvaging the CH-53A chopper so it could be
searched for remains. They built a dam around the helicopter and pumped out
the water and sand.

"Despite a quarter century of squalls, tides and scavengers, the
investigators managed to recover 161 human bone fragments and a few
personal effects - all that was left of the GIs, according to Tom Holland,
scientific director for the Army's identification lab.

"Later, scientists determined that the bones came from 13 different men. It
took another three years to "harvest" enough DNA from the bones and then
match it with DNA samples taken from maternal relatives to definitively
identify nine of them."

"That left four men unidentified. The remains of three of them were too
small to obtain a DNA sample."


Three Marines were left behind on Koh Tang.  They are Joseph Hargrove, Gary
Hall and Danny Marshall.  In the almost 25 years, since that battle, we
wonder if anyone has ever explained to the Hargrove, Hall and Marshall
families how these men were "inadvertently left behind."  Or, why it was "to
late" to go back for them.    Imagine what these men thought as they waited
for rescue and their thoughts when they finally realized no one was coming
for them.


One Families Thoughts - The following was sent to us, by Sandy Hargrove.
She is the sister-in-law of Joseph Hargrove, "inadvertently left behind" on
Kho Tang Island.

"Joseph Hargrove was lost on May 15th 1975 his 24th birthday. I know the
whole Hargrove family just knows that Joseph was sacrificed. We were never
told the truth."

"Joseph's older brother Lane was killed on April 21,1968. When Lane was
going over he was asked if he wanted to go to Canada by one of his older
brothers who had already done his time in the Army. Lane said no he wanted
to  go to Nam."

"In those days we honestly believed that the government cared about  us as
people. They wouldn't send someone to a foreign country and have him  risk
his life for no reason... or would they. What we know now and what we  knew
then.  With all that we have gone through I think we would have all gone  to
Canada with him."

"So Lane was blown up stepping on a land mine and his  little brother Joseph
just got left behind. So will someone tell me how this  country is a better
place because it is missing Joseph and Lane Hargrove.  Joseph is a human
being not a number. How dare anyone to think they can just  forget about
them. If it wasn't for Ralph writing that article in Popular  Science over a
 year ago I would still get the standard reply I usually get  when I mention
the Mayaguez. "The What?"

"Well Joseph never came home because  of that What. How easily people forget
. But now there is a movement out there  to hold the government accountable.
I love my country don't get me wrong but  the people who run it haven't done
a very good job as far as Viet Nam. If  anything I hope the guys deaths will
prevent this from happening again."

"There  are other little Hargroves growing up now Thank you God. Maybe they
all will  have a chance to grow up and have families not just some of them.
The  families that Lane or Joseph never had,  leave a big empty spot at the
family  reunions."      Sandy Hargrove

MIA Marines Identified From Mayaguez Incident - From the Office of the
Assistant Secretary of Defense - News Release  May 18, 2000 - "Six
Marines missing in action from the Vietnam War have been accounted for
and their remains are being returned to their families for burial in the
United States ."

"They are identified as Lance Cpl. Gregory S. Copenhaver, Port Deposit,
Md.; Lance Cpl. Andres Garcia, Carlsbad, N.M.; Pfc. Walter Boyd,
Norfolk, Va.; and Pfc. Kelton R. Turner, Los Angeles, Calif.  The names
of two Marines are being withheld at the request of their families."

"...Between 1991-99, U.S. and Cambodian investigators conducted seven
joint investigations, led by the Joint Task Force-Full Accounting.
Additionally, on three occasions Cambodian authorities unilaterally
turned over remains believed to be those of American servicemen.  In
October and November 1995, U.S. and Cambodian specialists conducted an
underwater recovery of the helicopter crash site where they located
numerous remains, personal effects and aircraft debris associated with
the loss.  The USS Brunswick, a Navy salvage  vessel, enabled the
specialists to conduct their excavation off shore. In addition to the
support provided by the Cambodian government, the Socialist Republic of
Vietnam also interviewed two Vietnamese informants in Ho Chi Minh City
who turned over remains that were later positively identified...."

"...Analysis of the remains and other evidence was made by the U.S. Army
Central Identification Laboratory Hawaii, which also conducted all the
remains recovery operations.  The CILHI made extensive use of
mitochondrial DNA as one of the forensic identification tools to
establish the identity of these men...."


Mayaguez Documentary - We hope you all saw the excellent documentary on
the Mayaguez incident aired by the Discovery Channel.  Titled "Seized at
Sea" this documentary provided detailed information on the actual battle
as well as the behind the scenes political decision making that led to
the ill-fated rescue.

An interview with one of the Cambodian soldiers provided information on
three Marines left behind alive.  According to the Cambodia the three
emerged from the jungle three days after the battle, seeking food and

The fate of the three, Joseph Hargrove, Danny Marshall and Gary Hall
remain unknown.


Another Question - viewers of "Seized at Sea" were left with is -- Just what
does the "I" in "CIA" stand for.  Based on the information provided by the
CIA for this operation the "I" sure didn't stand for "Intelligence."


Mayaguez Correction - In the last edition of "Bits" we referred to the
Mayaguez as USS Mayaguez.  The correct designation is S.S. Mayaguez. The
difference, USS denotes a United States Naval Ship.  The S.S. denotes a
commercial freighter.  The Mayaguez was a civilian ship. Thanks to Dewey
Martin, U.S. Merchant Marines (Ret) for bringing this to our attention.


POW/MIA agency dig site could hold Marine missing from Vietnam War

By Matthew M. Burke

Published: February 12, 2015

The newly established Defense POW/MIA Accounting Agency has dispatched a remains recovery team to the
Cambodian island of Koh Tang, 
where three Marines were left behind following the final battle of the Vietnam War.

The excavation site is believed to hold the remains of Lance Cpl. Joseph Hargrove, Pfc. Gary Hall or Pvt. Danny
according to official documents from DPMAA’s predecessor, the Joint Prisoners of War, Missing in
Action Accounting Command.

The three-man gun team was left behind in the confusion of a troop withdrawal following a brutal May 15, 1975,
battle between about 200 U.S. Marines and entrenched Cambodian Khmer Rouge soldiers in what became known
as the “Mayaguez Incident.”

The dig began Jan. 14 and is expected to run through the end of March....

Shortly after midnight on May 15, 1975, three Marines made up an M-60 machine gun team that was part of a Marine force making a helicopter-borne assault on enemy holdings on Koh Tang Island, Cambodia. They participated in combat operations throughout the day and were not known to be injured or wounded at any point. On the evening of May 15 orders were given to pull back to the beach of the island for extraction and to set up a new defensive position. The three Marines left their initial defensive position and started back to the beach; however, only one was sighted on the beach, and when the extraction was finished that night, all three Marines were missing. Enemy activity in the area prevented a return to the beach in order to search for them, and they remain unaccounted-for. 

Private First Class Danny Glen Marshall entered the U.S. Marine Corps from West Virginia and served in Company E, 2nd Battalion, 9th Marine Regiment. He was a member of this M-60 machine gun team, and went missing during this operation. Attempts to locate him or his remains following his team's disappearance were unsuccessful. Today, Private First Class Marshall is memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific. 

Based on all information available, DPAA assessed the individual's case to be in the analytical category of Active Pursuit.

If you are a family member of this serviceman, DPAA can provide you with additional information and analysis of your case. Please contact your casualty office representative.
