SYNOPSIS: On April 21, 1967, SP4 Thomas A. Mangino, squad leader; PFC Paul
Hasenback, PFC David M. Winters and PFC Daniel R. Nidds, riflemen; were
returning from a combat patrol in the second of two sampans 100 meters apart
near Chu Lai, Quang Ngai Province, South Vietnam.

Just before arriving at their destination, a Vietnamese civilian was seen
moving in his sampan toward the sampan carrying SP4 Mangino's squad. Another
sampan with 3 Vietnamese women was moving toward the first sampan, in which the
platoon leader rode. The first sampan started to leak, so proceeded faster
around and headed toward the beach. The Vietnamese women were still following
the first sampan. The distance between the two sampans carrying the Americans
was 200-250 meters.

The last time the platoon leader saw Mangino's sampan, the Vientamese civilian
was talking with SP4 Mangino's squad. The platoon leader's sampan arrived at
the beach 45 minutes later, and waited 20 minutes, then reported to the command
post that Mangino's sampan had not yet arrived.

Two hours after the platoon leader's sampan beached, SP4 Mangino's sampan had
still not arrived, so search efforts were begun. Two platoons searched the
area, and a helicopter searched from the air using a loud speaker. All efforts
were unsuccessful in locating Mangino and his squad.

Navy divers searched the river area without success. All aboard Mangino's
sampan knew how to swim. The Army strongly suspects that the enemy knows what
happened to Mangino and his squad.

Although returned POWs did not report having seen the men lost on the sampan,
Nidd's photo was identified by a refugee as having been a prisoner of war. The
circumstances surrounding their loss indicates the strong possibility, at
least, that the enemy forces knew their fates.

Mangino and his squad are among nearly 2500 in Southeast Asia who did not
return from the war. Unlike "MIAs" from other wars, most of these men can be
accounted for. Further, and even more significant, mounting evidence indicates
that there are hundreds of them still alive in captivity.

Refugees fleeing Southeast Asia have come with reports of Americans still held
in captivity. There are many such reports that withstand the closest scrutiny
the U.S. Government can give, yet official policy admits only to the
"possibility" that Americans remain as captives in Southeast Asia.

Until serious negotiations begin on Americans held in Southeast Asia, the
families of nearly 2500 Americans will wonder, "Where are they?" And the
families of many, many more future fighting men will wonder, "Will our sons be
abandoned, too?"

REFNO: 0646 19 Apr 76


1. On 21 April 1967, SP4 Thomas Mangino squad leader, and PFC's Paul A.
Hasenbeck, David M. Winters and Daniel R. Nidds, riflemen,- were returning
from a combat patrol in Quang Ngai Province in South Vietnam in the second
of two sampans. Just before arriving at their destination, in the vicinity
of grid coordinates BS 622 987, a Vietnamese civilian was seen moving in
his sampan toward the sampan with SP4 Mangino's squad. Another sampan with
three Vietnamese women was moving toward the first sampan in which the
platoon leader rode. The first sampan started to leak, so proceeded faster
around a jetty toward the beach. The Vietnamese women were still following
the first sampan, as they had loaned it to the platoon. The distance
between the two sampans carrying the platoon was now 200 to 250 meters. The
last time the platoon leader saw the second sampan the Vietnamese civilian
was talking with SP/4 Mangino's squad. The first sampan arrived on the
beach 45-minutes later. The platoon leader waited 20 minutes more and then
reported to the command post that the second sampan had not arrived.

2. Two hours after the first sampan beached, SP4 squad still had not
arrived, so a search effort was begun. Two platoons searched the area, and
helicopters, one with a loudspeaker, searched from the air. All efforts
were unsuccessful. Naval divers searched in the area of the last sighting
(vicinity BS 622 987) without success. All personnel on board the second
sampan could swim. (Ref 1)

3. An informant reported that on 5 May (1967) he had seen four US prisoners
of war who had been captured at (GC) 630 005 by a Viet Cong unit on the
date of this incident. (This information correlates well by time and
location, although there is no other information available for
verification. (Ref 2)

4. During the existence of JCRC,, the limited information available
precluded any efforts toward the resolution of this case. These
individuals' names and identifying data were turned over to Four-Party
Joint Military Team with a request for any information available. No
response was forthcoming.

5. SP4 Mangino, and PFC Winters are currently carried in the status of
Missing in Action. PFC Hasenbeck and PFC Nidds are carried in the
presumptive status of Dead, Body Not Recovered.

JEFFERSON CITY, Mo. -- (Missourinet) Missouri has 15 Vietnam War soldiers who are considered
unaccounted for.

A state House committee has unanimously passed a resolution that would urge a federal agency in
charge of recovering missing U.S. soldiers to make it a priority to resolve the open Missouri cases.

The Defense POW/MIA Accounting Agency's mission is to fulfill the task of bringing home America's
Prisoners of War and Missing in Action from all past wars and conflicts around the world....

Subject: Re: DPAA Hasenbeck Information
To: "Burgess, Dan (Blunt)"

Once again, thank you for your prompt attention to the case of Paul Hasenbeck,
which has been a persistent burden to the Hasenbeck family and their wide circle
of friends for nearly fifty years. I have visited with members of the Hasenbeck family
and we have jointly developed a response to the summary document attached to
your email of March 29, 2017, and the response is attached hereto.
I will look forward to continuing communication with you as the situation advances
toward a conclusion.

Best Regards,

The summary, transmitted by email from Dan Burgess dated March 29, 2017, recites
a narrative of expeditions to dig up grave sites suggested by witnesses whose testimony
should be considered minimally reliable. The DPAA and/or other agencies of the U. S.
government have on record evidence of witness accounts that would contradict accounts
leading to the excavated sites mentioned in the summary. The Hasenbeck family had not
been informed prior to the delivery of this summary of the three excavations that occurred
in 2015. Available U. S. Government intelligence reports indicate capture of the personnel
that have become known as the Mangino Four, not burials.

We would suggest that an investigation today begin with the artifacts from Paul Hasenbeck’s
wallet that have been seen on display at the War Museum in Hanoi around 1992. Detailed
photographs of this material have been in the possession of the DPAA and were distributed
widely. It should be possible, based on coded information on reverse side of the artifacts,
to trace them back to a point of origin and the disposition of the men they belonged to when

The Government documents contradicting the Vietnamese witness accounts should be found
in the19 inch classified file on Paul Hasenbeck in possession of the Department of Defense
at the Pentagon. In case there is difficulty in locating these reports, Jeanie Hasenbeck, sister
of Paul Hasenbeck, is willing to provide copies.

Jeanie Hasenbeck retains in her possession records of numerous contacts with U. S. Government
agency personnel related to this case. She is willing to make this information available under
proper circumstances to qualified persons who are involved in the effort to resolve the case
of the loss of her brother.

Return to Service Member Profiles

On April 21, 1967, two groups of four Americans each were aboard two sampans (small wooden boats) on the Tra Bong River near Quang Ngai Province making a return trip from a forward combat patrol. During the journey, the first sampan developed a leak, and the boat accelerated around a peninsula in order to reach shore as fast as possible; however, this broke visual contact between the two boats. The first sampan reached shore and waited for the second sampan, but it never appeared. The second sampan was last seen being escorted by a group of Vietnamese fishermen. Immediate searches of the area were unsuccessful in locating the missing boat or the four men who were aboard it. Extensive dives in the river and aerial searches were conducted in the days following the disappearance but were similarly unsuccessful. 

Staff Sergeant Paul Alfred Hasenbeck entered the U.S. Army from Missouri and served in Company D, 4th Battalion, 31st Infantry Regiment, 196th Light Infantry Brigade. He was aboard the second sampan when it went missing, and attempts to locate him or his remains following the incident were unsuccessful. Today, Staff Sergeant Hasenbeck 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.
