OPERATION TRACER
(STAY BEHIND CAVE)
“All around the World, different
countries and places have tales of mystery and intrigue, legends
and stories that fuel the imagination. Gibraltar is no different
to the others. Recollections and rumours from locals and
servicemen about ”Operation Tracer” or “Operation Monkey” (as it
was locally known,) have persisted through the years about this
potentially suicidal World War Two plan. But a few years ago the
members of the Gibraltar Caving Group found the actual site,
mystery solved? Not really, because there is still a lot of
information missing and that probably will remain so for many
years to come”
The story of the Stay
Behind Cave (also sometimes referred to as Braithwaite’s Cave,
after Major Braithwaite who led the team building the complex,
and who in fact died when a tunnelling charge went off
accidentally) has been told to visitors on the popular Second
World War tunnel tours for many years. Tales of how volunteers
would brick themselves into rooms dug out of the tunnel walls to
monitor German troop and equipment movements in the event of the
Rock falling into enemy hands. The rooms would be equipped with
radios and all the necessary supplies to enable the men to carry
out their task. It was said that a bath of lime would be
installed, so that if any of the servicemen died they would be
placed in the bath, which would dissolve their remains and
eliminate any smell. When the final occupant of the cave met the
same fate it would not really matter. The only thing about this
was that the location the tourists were shown would not have
provided the required field of vision needed for monitoring
events. The Gibraltar Caving Group analyzed where they thought
the cave should be, if it still existed, and agreed that it had
to be high up because it would need to have an excellent view of
both the Mediterranean and the Bay across to Algeciras.
Records released show
that British Intelligence planned, in 1941, to seal six men
inside the Rock of Gibraltar in the event that it fell to the
Nazi forces. The plan was devised shortly after the fall of
France and sources indicated that the German Forces were about
to make an attempt to move through Spain and take the
strategically placed Rock. It was decided to construct the
cavern system high up inside the existing tunnels to provide a
spy position to monitor the German ship movements. Potential
volunteers were told that if accepted they would be bricked up
in the cave and that they would have no way out.
An expert on survival
techniques, George Murray Levick, who had been on Scott’s
expedition to the Antarctic was recalled by the navy, at the age
of 64, and given the rank of Surgeon Commander to advise on how
to exist in such conditions. They were to be given enough
supplies to last them for seven years and Levick’s role was to
advise on psychology, diet exercise, recreation and the use of
alcohol and tobacco. Also he was tasked with suggesting the
correct clothing for the men, ventilation of the cave,
sanitation and how to deal with those who died, “by embalming
and cementing up”. It also is recorded that Levick actually
spent seven months in an igloo, alone, and recalled how he used
to hallucinate about walking down a street full of sweet shops,
but it was always in the afternoon, and it was half day and
early closing.
This plan was in fact so
secret that no discussions took place in Whitehall, they were
conducted at 36, Curzon Street, Mayfair the home of Admiral John
Godfrey the then Director of Naval Intelligence.
Construction work was conducted in
secret so that even the men involved in the tunneling were
unsure of its exact location. All of the workers involved were
immediately posted back to England after completion of the
project and not deployed overseas again for fear they might
reveal the existence of the plan.
One day, back in 1997,
the members of the Gibraltar Caving Group, Mark Ainsworth, Ian
Bramble, Richard Durrell and Jean-Paul Latin were high in the
tunnels when they noticed a draught coming from one of the
tunnels walls. It was strange; it had to be coming from
somewhere. Upon investigation, after making a small opening,
they found a brick wall and behind this they noticed the wooden
frame of a door leading to a previously undiscovered tunnel.
Entering into the darkness they realized what they had found. It
wasn’t just a cave it was a complete purpose-built tunnel system
within the existing tunnel system. Elation was not the word;
they had discovered “Stay Behind”. The myth had been exploded
and for three months they kept the existence and actual location
a closely guarded secret, while they conducted further research.
The floor of the main
hall had been covered in cork tiles to reduce any noise and to
provide some insulation and it was of sufficient dimensions to
permit the men to exercise. At one end of the room, in the
walls, they found a 10,000-gallon water tank filled from a water
catchment high in the Rock. There was a brass tap in the wall
with an area where the water could drain away naturally. When
eventually they managed to turn the tap on, what came out was a
thick sludge, but after a short while, it became clear cool
water. On one occasion the tap was left running for six hours
and the following day the tank was found to be full again (Good
British Workmanship!). The floor area nearer the entrance was
found to be covered in loose soil and rubble; it is thought that
this was where, if necessary, they would have buried the dead.
Going on from the main room towards a set of steps, the toilet
area was discovered and opposite was what used to be the radio
room. By the side of this room were the rusting remains of a
bicycle A leather strap, probably to cut down on noise, had been
used to replace the standard drive chain. This was used as a
generator to recharge the radio batteries (and to give the men
some other form of exercise). When it was the prearranged time
to send their signal, to avoid any interference with contact
with the rock, the aerial was fed down through an asbestos pipe.
Immediately after the broadcast the aerial was brought back into
the complex. The steps led up to what is now known to be the
Eastern Observation Post (OP), from here it was possible to
monitor shipping for miles, also at this OP it was possible for
the men to clamber out on to a small ledge, where undetected,
they were able to be in the fresh air. Halfway up these steps
was another set leading to the Western OP; here there was a very
small slit, which gave excellent views of the bay and the
shipping that would have been present. On the ground there was a
small slab of concrete that was used to block up the slit so
that it became invisible from the outside. Incidentally when the
group were trying to write some notes one day, the light from
the open slit shone on to the piece of paper, and acting like a
pinhole camera, projected a picture of the bay on to it.
Conditions would have
been spartan inside to say the least. There would have been
accommodation for probably six-men, all volunteers, comprising
of an Officer, a Surgeon and four Signalers (all who would have
had their appendix and tonsils removed before going into the
cave). Lighting, it is thought, would have been from fat burning
lamps, so as not to give off any smell, and food would have
consisted of something like chemically heated soups, dried
rations and powdered foods. It would certainly have been
claustrophobic living in such conditions with five other men, so
it is thought that strict psychological vetting would have been
used in the selection of the candidates to ensure they were of
the highest quality with stable characters. The individual names
of the men are not known, all were probably Royal Navy, but it
is suggested that Surgeon Lieutenant’s Cooper and Milner of the
RNVR could have possibly been involved, as they are listed as
being attached to HMS Cormorant on the orders of the First Sea
Lord. Others were trained at the Naval School in Shotley,
Suffolk before being sent to Gibraltar with ”Proper Jobs” as a
cover for the real purpose of their assignment. It was not until
August 1943, with the pressure on the new “Eastern Front” and
the redeployment of the German Forces that it was decided to put
the operation on ice. However further records show that very
similar Tracer type operations were also planned for Malta,
Colombo, Trincomalee and Aden.
No manuals or papers on
the operation have ever been found, indeed if they ever existed.
Reports say they did, but what we don’t know now will most
likely remain a secret forever, unlike “Stay Behind Cave”
itself.

FORGOTTEN PLAQUES IN GIBRALTAR
“Their Lordships desire me to express their
deep regret at the loss of the USS Tampa. Her record since she
has been employed in European waters as an ocean escort to
convoys has been remarkable. She has acted in the capacity of
ocean escort to no less than 18 convoys from Gibraltar,
comprising 350 vessels, with a loss of only two ships through
enemy action. The commanders of the convoys have recognized the
ability with which Tampa carried out the duties of ocean escort.
Appreciation of the good work done by the USS Tampa may be some
consolation to those bereft and Their Lordships would be glad if
this could be conveyed to those concerned”
This is the signal
sent by the British Admiralty to Admiral William S. Simms, the
senior U.S naval officer on duty in Great Britain, following the
tragic loss of the USCGC Tampa on 26th September
1918.
Originally named
Miami, the cutter was built by Newport News Shipbuilding, Newport News,
Virginia. She was launched on 10th February 1912 and
commissioned into service on 19th August of that
year. During 1913, following the loss of the Titanic the
previous year, she was despatched with the cutter
Seneca
to Halifax, Canada
on iceberg patrol, returning to her Key West, Florida base in
the July where she was based for the next few years, (she was
renamed Tampa
in early 1916). With the United States entry into World War One,
she was fitted with four 3-inch guns, and in September 1917 set
out for European waters
Along with the
cutters Yamacraw, Ossipee, Algonquin,
Manning and
her companion ship on ice patrols, the
Seneca, Tampa
made up Squadron 2 of Division 6 of the Atlantic Fleet Patrol
Forces based in Gibraltar. Tampa
conducted escort duties to 18 convoys, comprising 350 ships,
from Gibraltar to Britain through the U-boat infested waters. It
was on one of these patrols, on September 26th 1918,
she was escorting a convoy to Milford Haven, Wales. It was a
dark windy night and the Tampa was in the Bristol Channel, when suddenly she left the convoy having
detected signs of an enemy submarine. At 20.45 the rest of the
convoy heard a large explosion, but could see nothing, and upon
arrival at Milford Haven it was discovered that
Tampa
was missing. Immediately a search party, comprising of U.S. and
British boats was sent out, but all that was found was some
wreckage and two bodies in U.S naval uniform. The German U-boat
UB-91,
whose commander reported sinking a ship in that vicinity at that
time, is believed to have torpedoed the 1180-ton USCGC
Tampa,
with the loss of her one hundred and thirteen crew.
Built by Newport
News Shipbuilding Company, Virginia, the USCGC
Seneca
was launched on the
18th March 1908 and spent her early life on routine
patrols in U.S. waters. She was briefly involved with the
Miami
(later Tampa),
on iceberg patrol duties in 1913, but mainly was used along the
eastern seaboard of the United States.
When the USA
entered the war on 6th April 1917, the
Seneca
was assigned to
Atlantic Fleet Patrol Forces, Squadron 4, based at Key West,
Florida. She was transferred to overseas duties and arrived in
Gibraltar on the 4th September 1917 to become part of
Squadron 2 of the Atlantic Fleet Patrol Forces. It was on her 26th
patrol, escorting 21 ships of convoy OM-99, on the 16th
September 1918, that the steamship
Wellington
was torpedoed, the Seneca
went to her aid and fired three shots at the submarine before it
submerged. The Wellington
was very badly damaged, but still afloat, and 11 of her crew had
refused to remain on board, so 20 volunteers from the
Seneca
went to help. In the evening a storm blew up and in the heavy
seas eventually the steamship began to list badly. The following
morning, just as the order to abandon ship was given, the
boilers exploded and the Wellington
slid beneath the waves. In all, 11 men from the
Seneca
were lost in the attempted rescue. Rear Admiral Grant, the
senior British naval officer in Gibraltar at the time said,
“LT. Brown (Seneca) and the gallant
volunteers set an example worthy of the highest traditions of
any Service or any Nation”.
