OPERATION CARPETBAGGER

The purpose of the Carpetbagger project
was to fly "Special Operations" to deliver supplies to resistance
groups in enemy occupied countries; to deliver personnel to the field and
occasionally to bring back personnel from the field. Combat with the enemy
was avoided as it only endangered the success of the mission. Enemy anti
aircraft installations and detector posts were skirted as widely as possible
in order not to reveal the presence or destination of a Carpetbagger
aircraft. To avoid action with the enemy flights
were ordinarily made at night and at low level. When it was necessary for an
aircraft to cross enemy held areas equipped with anti-aircraft defences, a
route was chosen which would expose the aircraft to the fire of light guns
only. Thus the altitude attained seldom exceeded 7,000 feet. As soon as a
dangerous area was passed the aeroplane dropped down to 2,000 feet or lower.
A low altitude made it more difficult for the enemy to detect the aircraft
either by sound or by radar detection devices. Obstacles on the ground
distort the sound of a low flying aircraft far more than they do the noise of
a high flying one, because of the sharper angles of sound reflection. Radar
and sound detection devices had less time in which to focus on a low flying
aeroplane, and the range of effective detection was shorter at low altitudes.
B-24 dropping containers in daylight The majority of Carpetbagger flights were
made during the moon period, or on those nights when the moon was out, making
the ground visible to the navigator and bombardier In order that accurate drops may be made,
pilots endeavoured to get down to within 400 to 600 feet of the ground and to
reduce their flying speed to 130 miles per hour or less. The low speed
reduced the chances of damage to parachutes, as the shock of opening is much
less at the slower speed. Personnel were normally dropped from a height of
600 ft with containers and packages being dropped from 300 - 500 ft Non moon period flights at night were made with the use of special navigation equipment: "Rebecca"; S-Phone and radio altimeter. By means of this equipment, the percentage of accuracy could be even greater than with ordinary visual pilotage, but reception parties had to have the ground counterparts of the S- Phone and Rebecca equipment and be able to use them expertly - something which was very difficult in territory occupied by the enemy. Thus, even in the dark periods, aircraft could fly low altitudes with only a slight increase in risk. However dark period operations were possible without S-Phone or Rebecca provided that the reception signals consisted of bonfires and provided there could be reference to prominent land marks which could be distinguished accurately in the dark, such as large rivers and lakes. |

CARPETBAGGER operations from the United
Kingdom fell into two periods. Beginning in January 1944 the USAAF delivered
supplies to resistance groups in France, Denmark, Norway, Belgium and Holland.
Most of the sorties were flown to support patriots in northern France.
The Maquis of Haute Savoie and other
mountainous areas were supplied from the Mediterranean theatre until after the
Normandy invasion; then large numbers of Eighth Air Force bombers were diverted
from strategic missions to make a series of mass drops. Bombers on shuttle
missions that terminated at Russian bases also dropped a small quantity of
supplies to the defenders of Warsaw, but most of the missions to Poland were
carried out by RAF and Polish planes.
The first period of CARPETBAGGER missions
ended in September 1944, after which there was a lull of three months, followed
by small scale activity until the last two months of the war in Europe. This
second period was characterised by an increase in the percentage of sorties
flown to Denmark and Norway, two countries that had received only a small
quantity of supplies in comparison with those delivered to France.
Between January and September 1944 the 801st
/ 492nd Bomb Group undertook 2263 separate missions of which, due to
various circumstances, 1577 (ie 69%) were completed satisfactorily. The
successful missions delivered to Occupied Europe: 662 "Joes"
(agents); 18,535 containers of supplies; 8050 "Nickles" (bundles of
4,000 propaganda leaflets); 10,725 packages of supplies; 26 pigeons (for messages,
not eating); and carried 437 passengers
OPERATIONAL CYCLE OF CARPETBAGGER MISSIONS
The following events at Harrington for
thirty six hours provides a good picture of the Carpetbagger operational
process.
Targets Received and Plotted
This process begins at 1700 hours, at which
time the Conference Room at Air Operations Headquarters, OSS, in London, via
the scrambler telephone gives S-2 (the intelligence officer at Harrington) the
list of approved targets for the following night. The targets are designated by
names and numbers (eg Wheelwright 11, Mixer 7) which refer to targets kept on
file and described in detail on Air Transport Forms No 6. During the evening,
S-2 plots these targets on a large operational map covering a wall of the
office of the Deputy Group Commander. The map is in a scale of 1 to 500,000, or
about ten miles to the inch. It shows topographical features, such as
elevations, rivers and forests. Any areas where Special Operation flights are
prohibited are clearly indicated on the map.

When a target is plotted, it is indicated by
a tab pinned to the map. The comparative priority of the missions is shown by
bits of coloured paper attached to the pins. British or Special Operations
Executive targets proposed for the same night are also plotted with distinctive
tabs.
Night's Targets Laid On
At about 0900 hours the following morning,
the Station Weather Officer advises the Commanding Officer, or his deputy, of
weather conditions anticipated in the target areas, and at that time it is
decided where it will be practicable to send Carpetbagger aircraft. Then the
Commanding Officer, or his deputy, selects the list of targets for the night,
considering the priority of requests for material in the field, the reception
record of the particular ground, the possibilities of enemy opposition, the
distribution of desired missions and the availability of aircraft and crews.
The list of selected missions is then telephoned to the London Conference Room
by the Intelligence Officer and if London has no practical changes to suggest,
the list is in effect for that night's operations.
Targets Assigned to Squadrons
At about 1100 hours, the Squadron Commanders
are called in and meet before the map in the Group Operations Room with the
tabs pinpointing the targets for the night. Together, the squadron leaders
select targets for their crews, balancing the difficult with the comparatively
easy, the distant with the near, so that each squadron finally will have about
the same work load. Any disagreement arising among the squadron commanders is
decided by the toss of a coin; or, the Commanding Officer may be called upon to
make the decision
Navigators Receive Targets
At about 1200 hours, the navigators of the
crews receive their targets from the Squadron Navigator, who has received his
list from the Group Navigator, who has been advised of the targets by S-2
Intelligence Officer.
In the meantime, S-2 officers have been
gathering briefing data, and preparing maps and special instructions.
At 1500 hours, each crew navigator turns in
a flight plan to his Squadron Navigator, who brings all his squadron flight
plans to the Group Navigator. The flight plans and courses are checked by the
Group and Squadron Navigators, and if necessary, changes are made. A take-off
time schedule is made up by the Group Navigator, who is an assistant S-3
Operations Officer. The take-off time schedule is posted and distributed to
Squadron S-3's.
S-2 Brief Crews
Also at about 1500 hours, S-2 Officers begin
meeting with officer members of each crew. Crew maps are checked for location
of the target (latitude, longitude and terrain features). The S-2 Officers use
large scale maps, 1 to 500,000 or 1 to 80,000, to ensure accuracy. Each crew is
briefed separately by an S-2 Officer and has the opportunity to study the S-2
map and to compare it with their own map. Their maps are called target maps and
are on a scale of 1 to 250,000 or about five miles to an inch.
Final Briefing
At 1630 hours, a final briefing session is
held for all crew members in the Nissen hut briefing room alongside the Group
Operations Building. A weather officer displays the weather map and gives a
complete explanation of conditions for each target area, stressing expectations
en route and at the home base on the return flight. Weather predictions cover
direction and velocity of winds, cloud conditions, icing conditions, the
likelihood of rain, sleet or snow. Then, the Intelligence Officer gives any
special information which may affect the crew. Next the Deputy Commander gives
general flying and dropping instructions, and finally the Group Navigator gives
instructions on the route to be followed whilst over England and the point and
altitude for crossing the English coast. He ends up by giving the men a 'time
check', on which all crew watches are synchronised.
During the afternoon, enlisted crew members
are briefed as necessary. The crew navigator briefs them on the course, the
type of reception signal, the code recognition letters for the target, and the
terrain features approaching and around the target. The radio operators are
handed a radio 'flimsy' just before takeoff. The 'flimsy' details all signals
information including the code letters, the ground challenge and reply letter,
and the colours of the day for flare signals over England, the navigational
radio beacons, direction finder stations in England, a list of the airdrome
signals for England and other navigational information, including the night's
bomber code used in communications between bombers and home stations. If
necessary, the Group Communications Officer briefs radio operators on special
information.
The crew navigators plot their targets on
the maps they will use on their mission, check the presence of flak from the
S-2 flak maps, select routes and check points en route to their target. The
crew navigator does this under the direction of his Squadron Navigator, using
the Intelligence library as needed.
Navigators plotting their proposed courses
Dispatchers, when the aircraft carries
special packages or personnel to be dropped, are briefed by the Group Armament
Officer, who is the Chief Dispatcher for the Group.
Preparation for Take-off
During the day, as they have an opportunity,
crews give their aircraft a pre flight inspection: A half hour test flight is
made with each aircraft scheduled for the mission, in order to test all the
equipment.
A quick engine check
Crews have a meal approximately two and a
half hours before take-off time, and arrive at their crew rooms, located in
Squadron Operations, about two hours before the take-off. The navigator then
receives up to the minute weather reports on a weather card, and turns in a
revised flight plan and estimated time of arrival to the Squadron S-3. The
pilot receives and distributes to his crew kits furnished by S-2 and containing
rations of candy and chewing gum, flares, purses and emergency packets. The
radio operator receives his 'flimsy' and the navigator his 'GEE' codes. It is
now about forty five minutes before take-off time, and the crew is driven out
to where their B24 aircraft is parked.
About three hours before the first scheduled
take-off, Group Operations telephone the flight plans of all aircraft to the
Movement Liaison Officer of the Aircraft Movement Control Section of the Air
Defences of Great Britain Command. This includes the 'RT', which is the
squadron callsign and the aircraft letter for recognition (eg Reachforth S-
Sugar), the times of crossing the English and enemy coasts and the proposed
landing times.
Loading the Aircraft
As soon as it is ready, the target list goes
to the OSS Liaison Officer at Harrington, so that he can draw up a list of
required containers and packages for which he arranges delivery to the air
drome. The containers are consigned to the Group Ordnance Officer, whose men
deliver the containers, first snapping on parachutes, to the aircraft where
Armament Section men stand ready to load the containers into the aircraft.

The packages are delivered to the Armament
Officer of the Group and are taken to the aircraft for loading. The OSS Liaison
Officer and his men check each aircraft to ensure that the proper loading is in
place.
Leaflets or 'Nickels' are handled by the
Armament Section, who deliver them to the aircraft in bundles of 4,000, as
received from the Cheddington warehouse of OWI/PWE, operating under the
direction of SHAEF. Usually six to ten bundles of leaflets are loaded according
to the stock on hand, the length of flight and the time over enemy territory.
For new areas, not previously well covered by leaflets, more leaflets will be
despatched if possible. (No leaflets are dropped near targets, for security
reasons. After leaving the target thirty to fifty miles behind, the dispatcher
drops the leaflets on villages and towns passed over on the homeward flight).
Personnel to be dropped are received at
Harrington by the Armament Officer and are controlled by his section until
loaded on the aircraft. Representatives from 'Special Operations', London,
escort all agents until they are loaded, supervise their dressing and assist in
their briefing for the drop.

Take - Off
The aircraft are now ready for the night's missions.
The crews warm up their aircraft and take off on schedule, proceeding
individually to their targets. As each aircraft takes off, the Flying Control
Section checks it out and reports this take off to Group Operations who
telephones the information to the Movement Liaison Officers of the Air Defences
of Great Britain Command at Stanmore.

Interrogation of Crews
When an aircraft has completed its mission
and returned to the home base, its crew are driven directly to the Intelligence
Library situated at the rear of the Group Operations Building, for
interrogation by S-2 Officers.
The interrogation find the crew showing the
stress of a hard dangerous mission which has lasted from five to eight hours.
Free, frank interchange of information is encouraged. The S-2 Officers handle
the jumpy crew with a great deal of tact and flexibility...

End of the mission
After the interrogation, the crew go to the
Mess Hall, where under the supervision of a medical officer, each man is given
a two ounce medicinal ration of whiskey. The man signs a receipt for his
whiskey, which is issued for operational use only and serves to relax tense
nerves.

Then the men get a good breakfast, including
fresh eggs, and go to bed. If any man has trouble getting to sleep, he is
supposed to ask the Medical Officer for a sedative.
The operational cycle ends as the men return
to their billets for a well deserved rest.
