During the Vietnam War pilots were issued one-of-a-kind escape and evade authenticator codes. These codes were issued in order to prevent the enemy from tricking rescue teams into an ambush.
The image that NSA analysts were studying took shape on June 5, 1992. It was such an authenticator code and it corresponded to that of Henry Serex. Moreover, so that there would be no doubt of the identity of the person cutting this code into the hillside, "-SEREX".
The Department of Defense PoW/MIA Office determined that the code, although identified as that belonging to, or assigned to, Henry Serex, was, in fact, a natural phenomenon and they dismissed this matter without demanding any answers whatsoever from Hanoi. We were, after all, about to lift the embargo and American business could not let a simple matter of a human being stand in their way.
What follows is the biography of Henry Muir Serex:

REMARKS:
SYNOPSIS: On the afternoon of April 2, 1972, two Thailand-based EB66 aircraft
(Bat 21 and Bat 22), from the 30th Air Division, were flying pathfinder escort
for a cell of B52s bombing near the DMZ. Bat 21 took a direct SAM hit and the
plane went down. The aircraft was observed by other flight members to break
apart and crash. A single beeper signal was heard, that of navigator Col. Iceal
Hambleton. At this time it was assumed the rest of the crew died in the crash.
The crew included Maj. Wayne L. Bolte, pilot; 1Lt. Robin F. Gatwood, LtCol.
Anthony R. Giannangeli, LtCol. Charles A. Levis, and Maj. Henry M. Serex, all
crew members. It should be noted that the lowest ranking man aboard this plane
was Gatwood, a First Lieutenant. This was not an ordinary crew, and its members,
particularly Hambleton, would be a prize capture for the enemy because of
military knowledge they possessed.
It became critical, therefore, that the U.S. locate Hambleton, and any other
surviving crew members before the Vietnamese did - and the Vietnamese were
trying hard to find them first.
An Army search and rescue team was nearby and dispatched two UH1H "slicks" and
two UH1B "Cobras". When they approached Hambleton's position just before dark,
at about 50 feet off the ground, with one of the AH1G Cobra gunships flying at
300 feet for cover, two of the helicopters were shot down. One, the Cobra (Blue
Ghost 28) reached safety and the crew was picked up, without having seen the
other downed helicopter. The other, a UH1H from F Troop, 8th Cavalry, 196th
Brigade, had just flown over some huts into a clearing when they encountered
ground fire, and the helicopter exploded. Jose Astorga, the gunner, was injured
in the chest and knee by the gunfire. Astorga became unconscious, and when he
recovered, the helicopter was on the ground. He found the pilot, 1Lt. Byron K.
Kulland, lying outside the helicopter. WO John W. Frink, the co-pilot, was
strapped in his seat and conscious. The crew chief, SP5 Ronald P. Paschall, was
pinned by his leg in the helicopter, but alive. WO Franks urged Astorga to leave
them, and Astorga was captured. He soon observed the aircraft to be hit by
automatic weapons fire, and to explode with the rest of the crew inside. He
never saw the rest of the crew again. Astorga was released by the North
Vietnamese in 1973.
The following day, Nail 38, an OV10A equipped with electronic rescue gear
enabling its crew to get a rapid "fix" on its rescue target entered Hambleton's
area and was shot down. The crew, William J. Henderson and Mark Clark, both
parachuted out safely. Henderson was captured and released in 1973. Clark evaded
for 12 days and was subsequently rescued.
On April 3, the day Nail 38 was shot down, a UH1H "slick" went down in the same
area carrying a crew of four enlisted Army personnel. They had no direct
connection to the rescue of Bat 21, but were very probably shot down by the same
SAM installations that downed Bat 21. The helicopter, from H/HQ, 37th Signal
Battalion, 1st Signal Brigade, had left Marble Mountain Airfield, Da Nang, on a
standard resupply mission to signal units in and around Quang Tri City. The
crew, consisting of WO Douglas L. O'Neil, pilot; CW2 Larry A. Zich, co-pilot;
SP5 Allen D. Christensen, crew chief; and SP4 Edward W. Williams, gunner; remain
missing in action.
On April 6, an attempt was made to pick up Clark and Hambleton which resulted in
an HH53C helicopter being shot down. The chopper was badly hit. The helicopter
landed on its side and continued to burn, consuming the entire craft, and
presumably, all 6 men aboard. The crew of this aircraft consisted of James H.
Alley; Allen J. Avery, John H. Call III, Peter H. Chapman, William R. Pearson,
and Roy D. Prater. Search and rescue noted no signs of survivors, but it is felt
that the Vietnamese probably know the fate of this crew because of the close
proximity of the downed aircraft to enemy locations.
On April 7 another Air Force OV10A went down in the area with Larry Potts and
Bruce Walker aboard. Walker, the Air Force pilot of the aircraft, evaded capture
11 days, while it is reported that Potts was captured and died in Quang Binh
prison. Potts, the observer, was a Marine Corps officer. Walker's last radio
transmission to search and rescue was for SAR not to make an attempt to rescue,
the enemy was closing in. Both men remain unaccounted for.
Hambleton and Clark were rescued after 12 incredible days. Hambleton continually
changed positions and reported on enemy activity as he went, even to the extent
of calling in close air strikes near his position. He was tracked by a code he
devised relating to the length and lie direction of various golf holes he knew
well. Another 20 or so Americans were not so fortunate.
In July 1986, the daughter of Henry Serex learned that, one week after all
search and rescue had been "called off" for Bat 21, another mission was mounted
to recover "another downed crewmember" from Bat 21. She doesn't know whether the
"other downed crewmember" is her father or another man on the EB66 aircraft. No
additional information has been released. When the movie "Bat 21" was released,
she was horrified to learn that virtually no mention of the rest of the crew was
made in the film.
In Vietnam, to most fighting men, the man that fought beside them, whether in
the air or on the ground, was worth dying for. Each understood that the other
would die for him if necessary. Thus, also considering the critical knowledge
possessed by Col. Hambleton and some of the others, the seemingly uncanny means
taken to recover Clark and Hambleton are not so unusual at all.
What defies logic and explanation, however, is that the government that sent
these men to battle can distort or withhold information from their families, and
knowingly abandon hundreds of men known or strongly suspected to be in enemy
hands.
Thousands of reports have been received by the U.S. Government indicating that
Americans are still alive, in captivity in Southeast Asia. It has been 17 years
for those who may have survived the 1972 Easter crashes and rescue attempts. How
much longer must they wait for their country to bring "peace with honor" to them
and bring them home?
Henry M. Serex was promoted to the rank of Lieutenant Colonel during the period
he was maintained missing.

I am sure that some of your remember the movie Bat 21 starring Gene Hackman and Danny Glover. Isn't it amazing that Hollywood can make movies showing Happy Endings (Hambleton being rescued) while men such as Serex, stemming from the same incident, are given "bit" parts and relegated as expendable by our own government. That his authenticator code, his name and distress designation were explained away as that of a natural phenomenon. But movies are made to show that the United States Government would expend all on the safe return of one man when in fact the Men We Left Behind are abandoned.
As if that wasn't enough, while the Serex authenticator code was taking shape, a few hundred feet away another code was picked up by our spy sattelites. This code, GX2527, proved to be that of Peter Matthes. To add insult to injury, the DoD explained this one away as another natural phenomenon. Hey, it worked once...
What follows is Peter Matthes biography:
MATTHES, PETER RICHARD
Name: Peter Richard Matthes
REMARKS:
SYNOPSIS: On November 24, 1969, a C130A departed Ubon Airfield, Thailand on an
operational mission over Laos. The crew aboard the aircraft included Maj.
Michael D. Balamonti (the navigator); Capt. Earl C. Brown; Capt. Richard O.
Ganley; 1Lt. Peter R. Matthes (the copilot); and Sgts. Donald L. Wright; Larry
I. Grewell; Charles R. Fellenz; and Rexford J. DeWispelaere.
While on the mission, near Ban Bac, Savannakhet Province, Laos, the C130 was
observed to be struck by several rounds of 37mm anti-aircraft fire, burst into
flames, crash to the ground, and explode on impact. All the crew was declared
Missing in Action, but due to enemy presence in the area, it was strongly felt
that the enemy could account for them. It was not determined whether the crew
died or survived the crash of the aircraft.
The crew of the C130 are among nearly 600 Americans who were lost in Laos. When
Dr. Henry Kissinger negotiated President Nixon's Peace Agreements in Paris in
1973, ending American involvement in the Vietnam War, the Americans lost in
Laos were forgotten. Kissinger did not negotiate for them, even though several
were known to be Prisoners of War, and some 125 of them were known to have
survived their loss incidents. Furthermore, the Pathet Lao stated on several
occasions that they held "tens of tens" of American prisoners.
The nearly 600 Americans lost in Laos have never been negotiated for, and not
one American held in Laos was released at the end of the war.
Since the end of the war, nearly 10,000 reports have been received by the U.S.
relating to Americans missing in Southeast Asia. Many authorities believe that
hundreds remain alive today, held captive. Whether the crew of the C130 could
be among them is not known, but it seems certain that there are compelling
questions that need answers. Among them - why did we abandon the men who served
our country? What are we doing to bring them home?

What we have here are two cases of captured pilots doing everything they can to get home, to resist the enemy as best as they can and having bureaucrats in Washington Dee Ceit decide that they aren't worth the effort to get them home. That is our national shame. Do not forget Henry Serex and Peter Matthes and do not let our elected representatives forget Henry Serex and Peter Matthes. Call your congressman and Senator today and demand that they vote against the McCain Ammendment to the Missing Service Personnel Act of 1996 and also advise your elected representatives that the U.S. Government's handling of the PoW/MIA issue is totally unacceptable to you. Do it now.
