b. recovery of chemical agents in kuwait
August 1991--Sabahiyah High School for Girls
The Committee staff has obtained British and U.S. Army
reports which document in detail the discovery of more than
250 gallons of dangerous chemical agents. According to the
units that were presents, mustard gas and another blister
agent were found in a storage tank in southeastern Kuwait.
These chemical agents were recovered in Kuwait, well inside
the Kuwait theater of operations, well inside areas occupied
by U.S. and British forces. According to the reports, they
had been placed there by Iraqi forces during the occupation
of Kuwait. The liquid was tested and over 20 times the
presence of chemical agents was confirmed.
The Committee staff has obtained a copy of a recommendation
for an Army Commendation Medal that was presented to Sergeant
James Warren Tucker for among other things ``participating in
the mission that located stores of chemicals agents'' while
deployed in Southwest Asia.\6\
Committee staff has also identified the commander of that
unit, Captain Michael F. Johnson, currently with the U.S.
Army at The Infantry School at Fort Benning, Georgia--who was
awarded a Meritorious Service Medal for his actions.\7\
These two soldiers and as many as six others from the 54th
Chemical Troop of the United States Army's 11th Armored
Cavalry Regiment were given Army medals for ``the positive
identification of suspected chemical agent,'' according to
the citation presented to Captain Johnson.\8\
We have obtained the actual reports from two NATO countries
who were Coalition members during the Persian Gulf War.\9\
This is a step-by-step analysis of the event as recorded in
documents and the testimony of Nuclear Biological and
Chemical, or NBC, officers who were there.
A container suspected of containing chemical agents was
located in southeastern Kuwait in an area about 50 kilometers
north of Saudi Arabia and 4 kilometers west of the Persian
Gulf. The precise coordinates are TN18832039 (Magellan)\10\
Maps showing the precise location in which this container was
found is attached.\11\
According to the British report, on August 5, 1991, several
months after the end of the Persian Gulf War, Major J.P.
Watkinson of the British Army received orders to investigate
a container that was believed to be leaking mustard gas.\12\
According to the official report prepared by Major
Watkinson on 7 August 1991, the request to investigate the
leaking container was made by Lt. Colonel Saleh Al Ostath of
the Kuwaiti Army and agreed to by Mr. Lucas of the Royal
Ordinance Corps.\13\
Major Watkinson and his unit, the 21st Explosive Ordinance
Disposal Squadron, were taken to the site of the Sabahiyah
High School for Girls and directed to a metal storage tank
with a capacity of approximately 2,000 liters. According to
the report, there appeared to be entry and exit bullet holes
of approximately 7.62 caliber in the container.\14\
A photograph of the schoolyard with some of the chemical
specialists approaching the tank that contained the chemical
agents is attached.\15\
According to Major Watkinson's report, the container was
leaking a brown vapor from both holes. The school was not in
use and there were U.S. civilian contractors clearing
explosives and rubbish from the area.\16\
The school security guard told the British that the tank
was not there before the war. He first noticed the tank when
he returned to the school after the war on March 20, 1991--
four and a half month prior to these tests. The British
report notes that the school was used as an Iraqi defensive
position during the war.\17\
Major Watkinson ordered all personnel to move up wind, and
after putting on his chemical protective clothing, approached
the container and tested the brown colored vapor with a
Chemical Agent Monitor (CAM).\18\
The Chemical Agent Monitor gave a reading of eight (
bars
on H, for mustard agent--a maximum reading indicating a
highly concentrated agent--and no bars on G, indicating no
nerve agent present.\19\
This was the first positive test for chemical mustard agent
at this location.
Distilled mustard is described in the Merck Index, a
handbook for chemists, as an oily substance. It is also
described as being amber brown in color--remember Watkinson's
report describes it as a brown substance.\20\
A photo and diagram of a Chemical Agent Monitor or CAM in
use showing the types of displays that a chemical detection
specialist would observe is attached.\21\
A 8-bar reading indicates a highly concentrated agent.
These monitors are still in use by both U.S. and British
forces.
Watkinson then tested the vapor with one color detector
paper and nothing happened. He used three color detector
paper and it turned pink indicating the presence of mustard
agent.\22\ This was the second positive test for mustard
agent.
On a second visit to the container, according to the
report, he inserted a wire with one of the bullet holes, and
according to his report, ``wiped the oily substance on both
types of detector paper.''\23\
Again the oily nature of the substance indicates a property
that is consistent with the properties of mustard agent.
The one color paper turned brown and the three colored
paper turned pink, the latter again indicating the presence
of mustard agent. This was the third positive test for
mustard agent. Major Watkinson then sealed both in the
container with masking tape.\24\
On yet a third visit to the container, the holes were
uncovered and the vapor was tested using an M18A2 chemical
detector kit. This test was repeated six times. On four of
the tests the color indicator immediately turned blue
indicating mustard (or ``H'') agent.\25\
For the remaining two tests, the color indicator went
yellow but later turned blue.\26\ There were the fourth
through the ninth positive tests for mustard agent.
Another wire dip test was conducted using the three color
detector paper from the M18A2 kit and the paper turned
pinkish/orange indicating mustard agent for the tenth time.
The bullet holes were resealed using industrial silicone
filler and plaster of paris bandages. The container was
checked with the Chemical Agent Monitor for leaks and the
area was secured.\27\
On August 7, 1991, the Commander of the 11th Armored
Cavalry Regiment was asked to send two FOX chemical
reconnaissance vehicles, in support of the Kuwaiti Ministry
of Defense and the Royal Ordinance Corps, to assist Major
Watkinson in confirming the presence of a chemical agent.\28\
Since this was a joint and combined live agent chemical
detection mission, involving both U.S. and British forces,
detailed rehearsals occurred to ensure that no mistakes were
made. The unit then travelled to the Sabahiyah High School
for Girls in southeastern Kuwait.\29\
On August 8, 1991, one FOX team moved to the area near the
container and began to conduct point surveys inserting the
detection probe of the FOX vehicle into the ground to a depth
of about four centimeters. The mass spectrometer showed
microdoses of chemical mustard agent in the ground.\30\ This
was the eleventh confirmation'
At the same time another collection team in full chemical
protective clothing walked to the container, estimated to
contain between 800-1000 liters, or about 250 gallons of
liquid, with Chemical Agent Monitors and other assorted
chemical detection equipment. This team removed the storage
container's seals and there was a discharge of pressurized
vapor into the air.\31\
Captain Johnson's report confirms that he saw a light
copper to amber colored vapor exit from the hole.\32\ Again,
mustard agent is described as an amber brown liquid.\33\
Tests were conducted with both the Chemical Agent Monitor
and chemical detection paper. The detection paper confirmed
the presence of chemical mustard agent; the twelfth
confirmation. The Chemical Agent Monitor registered eight
bars, again confirming highly concentrated mustard agent.
This was the thirteenth confirmation of mustard agent by the
specialists present.\34\
Captain Johnson's unit then inserted a medical syringe with
a catheter tube into the container to extract liquid agent
for detection paper, Chemical Agent Monitor, and FOX
testing.\35\
The sample was placed into a metal dish. By the time a
ground team member moved to the rear of the Fox to the probe,
there was not enough liquid available to get a reliable
reading.\36\
Another attempt was made and the ground team extracted a
larger sample of liquid and placed it into the metal dish.
The dish was moved to the FOX probe and the liquid was drawn
for analysis--not random vapors--not oil fumes--but the
actual liquid chemical agent. Within six seconds, the mass
spectrometer detected and identified the liquid as highly
concentrated mustard agent.\37\ Both four point and full
spectrum readings were obtained, according to Captain
Johnson, in each of the mass spectrometer analyses.\38\ This
therefore was the fourteenth (4 point) and fifteenth (full
spectrum) confirmation of mustard agent.
Further analysis by the system also indicated the presence
of traces phosgene, a non-persistent choking agent, and
phosgene oxime, a blister agent. Another test was conducted
to validate the findings. Again the Fox vehicle confirmed the
presence of mustard agent for the sixteenth and seventeenth
time, and again phosgene, and phosgene oxime were
confirmed.\39\
Captain Johnson ordered yet another mass spectrometer test,
utilizing the second FOX vehicle. The team in the second
vehicle was not informed of the findings of the first
vehicle, to rule out any possibility of biased readings from
the team in the second vehicle. The team in the second FOX
vehicle repeated the test and reported the same findings
except that this time the reported levels of phosgene oxime
were much higher. They also performed a second test to
confirm their results. Again both 4-point and full spectrum
analysis was conducted during each of these tests.\40\ These
were the eighteenth through twenty-first confirmations.
While the Chemical Agent Monitor and many other chemical
detection kits available to military forces only detect H, or
mustard agents, and G and V nerve agents, the FOX chemical
reconnaissance vehicle accurately detects 60 known chemical
agents using a computerized mobile mass spectrometer.\41\
It is capable of identifying the individual component
chemical elements, such as sulfur, hydrogen, chlorine, and so
forth; their molecular composition; and their molecular
weight. This provides a scientific means to precisely
identify substances.
In response to a request by the Committee for an
explanation from the Department of Defense, Dr. Theodore
Prociv, Deputy Assistant for Chemical and Biological Matters
(Atomic Energy), replied on July 26 that the Department of
Defense analysis of the FOX tapes revealed that the ions
matched in three of four categories for a mustard agent, but
matched nitric acid in all four categories.\42\
Committee staff solicited an opinion from the National
Institute of Standards and Technology regarding the accuracy
of this explanation.\43\
On September 6, in response to several specific questions,
Dr. Stephen Stein, of the Institute, replied that ``HD
[mustard] has no major peaks in common with those expected to
arise directly from fuming nitric acid,'' and that it is
``highly unlikely that a properly functioning mass
spectrometer would produce any of the major peaks of nitric
acid or nitrogen oxides from HD.'' Furthermore, ``if fuming
red nitric acid did not decompose prior to detection
(ionization) there would be no possibility of mistaking it
for HD.''\44\
The commander of the unit said that the tests were run
using both the four principle mass peaks and full spectrum
analysis on the substance in question. The tests were run
twice each by two FOX vehicles. The mass spectrometers were
checked for calibration before and after each test, with no
problems noted.
Each of the four tests identified identical substances--
namely; mustard agent and phosgene oxime. When asked
specifically, ``how likely is it that under these
circumstances that the computer algorithm identified nitric
acid as these substances,'' Dr. Stein responded that ``if
fuming red nitric acid did not react prior to detection,
there is no likelihood that either the four peak analysis or
the full spectrum analysis would lead to false identification
of mustard.''\45\
And, ``if nitric acid did react, the reaction products
might generate a large number of peaks. Some of these might
fortuitously be those characteristic of HD or other chemical
agents and therefore might produce a false positive 4-peak
identification of HD. A robust full spectrum matching
algorithm, however, would not be expected to falsely identify
mustard.''\46\
The ground collection team then extracted a larger sample
from the container and prepared it for transport from the
area for further testing and evaluation.\47\
According to Captain Johnson's report and other eyewitness
testimony, a member of the British team was injured while
collecting a sample of the chemical agent. Some of the liquid
agent made contact with the soldiers left wrist. The soldier
immediately reacted to the liquid and was in severe pain and
was believed to be going into shock.\48\
The injured soldier was quickly taken to a decontamination
site and covered with decontamination powder and cut out of
his chemical protective clothing.\49\ A photograph of the
British soldier on the FOX vehicle and his clothing laying
in a pile beside the vehicle is attached.\50\
Dr. Prociv in his July 26, 1994 letter to the Committee
reported that the injured soldiers clothing had been found by
the British government to have been burned by fuming nitric
acid in tests conducted at Porton Down.\51\ Previously, in
response to direct questioning by Committee Staff, Captain
Johnson stated that the contaminated suit was burned, that
is, incinerated, at the site.\52\
The decontamination team then doused the soldier with a
decontamination solution. Within one minute, a small blister
was observed forming on his left wrist the size of a pinhead.
About five minutes later, the blister had already reached the
size of a U.S. fifty cent piece coin. Medics on the scene
screened the victim for residual liquid contamination and
sent him to the hospital for further treatment. After the
casualty was evacuated, the rest of the unit and equipment
was decontaminated.\53\
According to Military Chemical and Biological Agents:
Chemical and Toxicological Properties, mustard agents acting
alone may take hours to form blisters, but phosgene oxime
acts within 30 seconds leaving a blanched area and
immediately forms a red rash-like ring. With phosgene oxime,
instant death from systemic shock or trauma is possible from
exposure.\54\
The reported reaction of the British casualty was as might
have been predicted when exposed to the identified agents.
The fate of this inured British soldier is unknown.
After completing their testing, the U.S. FOX team leaders
were ordered to remove the tapes from the mass spectrometer
of the FOX vehicles by Lieutenant Colonel Killgore, the
chemical officer for Task Force Vicotry.\55\ These tapes are
the paper records of the chemical breakdown of the liquid or
vapors and are produced by the mobile mass spectrometer in
the FOX vehicle.
The tapes and the collected samples were reportedly turned
over to personnel wearing desert camouflage uniforms with no
rank or distinguishing patches.\56\ Captain Johnson does not
know what happened to the tapes or samples as he was ordered
from the scene after his unit's mission was completed.\57\
Dr. Prociv in his written response to the Committee stated
that these were U.N. personnel. According to Lt. Colonel
Killgore, while they were United Nations personnel, they were
assigned to the U.N. team from the British Chemical and
biological Defense Establishment at Porton Down--British
Ministry of Defence employees.\58\ In a subsequent inquiry,
the U.N. could produce no written records of the findings of
the U.N. team at the site.
Conclusions--
Chemical mustard agent was detected by: chemical
specialists from the British Army using a Chemical Agent
Monitor, M18A2 chemical agent detector, and detector paper;
and, chemical specialists from the United States Army using a
Chemical Agent Monitor, detector paper, and two mass
spectrometers.
Phosgene oxime was detected by: two sophisticated FOX
vehicles' mass spectrometers.
These were direct samples--not random vapors collected by
the vehicle--as in previously reported cases.
As cited above, mass spectrometry is capable of identifying
the individual chemical elements, such as sulfur, hydrogen,
chlorine, and so forth; their molecular composition; and,
their molecular weight. This provides a means to precisely
identify substances. This was not an intake of random fumes
by a moving vehicle in heavy smoke, it was a direct analysis
of liquid agent drawn from the container.
This was not the only confirmation of the identity of the
chemical agents present--the results were confirmed by nearly
every detector deployed with U.S. and British forces--in a
controlled setting.
A British soldier who came into contact with the liquid
blistered immediately and appeared to be going into shock--as
might be predicted from the nature of the agents present.
The tapes were ordered removed from the vehicle and forward
with a sample of the chemical agents. The soldiers were
ordered to given the materials to individuals in unmarked
uniforms and Captain Johnson, who earlier this year, after
hearing that the Department of Defense was denying the
presence of chemical agents in Kuwait, forwarded the report
on this incident through his chain of command, and had the
report returned to him. It was not forwarded to the
Department of Defense.
The Kuwaiti, U.S., and British governments all received
reports on this recovery of bulk chemical agents.
While these reports are not classified, the Department of
Defense has consistently maintained that no chemical agents
were located in areas occupied by U.S. forces--including in
testimony before committees of both the House of
Representatives and the Senate.
The Department of the Army originally told Committee staff
that prior to releasing Captain Johnson's report they must
obtain clearance from the Department of Defense, and that an
intelligence review must be conducted.\59\ That would seem to
contradict the claim that there is no classified information
on this subject. They claimed that prior to releasing the
British report, they must get the permission of the
British.\60\ However, when British report was received, it
was dated July 14, 1994, indicating that it had been prepared
in response to the Committee request, in coordination with
the Department of Defense.\61\
The Committee was not provided with an official British
report dating from the time of the incident by the Department
of Defense as requested. A copy of that report was obtained
by the Committee outside of Department of Defense channels.
This official report, dated August 7, 1991, confirms that
mustard agent was detected, and that the substance was oily,
like mustard agent.\62\ Nitric acid is not oily.
The U.S. report, prepared by Captain Johnson, confirms that
not only was mustard agent detected in the container using a
mass spectrometer, but also in microdoses on the ground.\63\
This would eliminate the explanation that the container held
fuming nitric acid--rocket fuel oxidizer--so concentrated
that if reacted with materials in the mass spectrometer
causing false readings when the material was examined. The
mass spectrometers in both FOX vehicles were also
successfully calibrated before and after this detection
event.
There is also the issue of how the Department of Defense
has handled this and other investigations into reported
chemical agent detection events. Committee staff continues to
receive reports from individuals, many of whom are no longer
in the military--civilians who have been contacted by high
ranking military officers assigned to work with the Defense
Science Board Task Force investigating this issue. We have
received complaints from veterans that rather than trying to
seek other witnesses or corroborate their reports, these
officers have called to convince them that they were
mistaken. That their findings were not credible--that their
statements made to Congress would be refuted.\64\ Most
recently, an individual associated with this detection of
chemical agents was contacted by one of these officers. This
officer specifically told the individual that these findings
would be refuted by the Department of Defense--even before
the Department received the report from the British that was
eventually forwarded to the Committee.
In this case there were 21 field tests conducted on this
substance which were positive for mustard agent; both U.S.
and British Chemical Agent Monitor readings confirmed 8 bars
for mustard gas, a maximum reading indicating the presence of
highly concentrated agent; 8 of 8 mobile mass spectrometer
tests, using two separate FOX vehicles and liquid agent in a
controlled setting identified identical substances--mustard
agent, and phosgene oxime; it was the same color as mustard
agent; it was oily like mustard agent; a mobile mass
spectrometer reading indicated that microdoses of mustard
agent were present in the soil; a British soldier suffered a
chemical injury consistent with what would be expected when
exposed to these agents, particularly to phosgene oxime; and
the Department of Defense explanation was described by the
National Institute for Standards and Technology variously as
``highly unlikely,'' ``no likelihood,'' and ``not possible.''
