The Air Invasion of Burma

The task for the US air commandos was to
insert Orde Wingate and his Chindits far behind enemy lines and support
them against Japanese forces.
The British military establishment
was not fond of Orde C. Wingate. He was eccentric in personal habits and
unconventional in his tactics, a practitioner of irregular warfare in
the mold of T. E. Lawrence—the famed “Lawrence of Arabia”—who was in
fact a distant cousin.
Wingate wore an old pith helmet that he had
gotten in Africa. When on campaign, he let his beard grow to save the
five minutes of shaving time in the morning. He quoted Aristotle, Plato,
and the Old Testament. He ate quantities of raw onions between meals
and carried a small alarm clock instead of a wristwatch. Some thought
Wingate a genius; others regarded him as strange and counterproductive.
In
February 1943, Wingate, then a brigadier general, introduced a
“long-range penetration” strategy to break Japan’s hold on Burma. He
called his soldiers “Chindits,” after the lion-like statues that guarded
Burmese pagodas. Wingate took 3,000 men—Gurkhas and Burmese troops—and
1,000 mules deep into the jungle where they operated inside enemy
territory for three months.

He
faced huge logistics problems. Supplies ran short, casualties were
severe because of inability to evacuate wounded, and there was
difficulty extracting the force at the end of the mission. Support from
the Royal Air Force was neither prompt nor sufficient.
British
military leaders regarded the operation as a costly failure, but Prime
Minister Winston Churchill was deeply impressed with Wingate and his
determination to take the offensive. Churchill took Wingate along to the
Quadrant Conference of Allied leaders in August 1943. Win-gate
impressed the President, Franklin D. Roosevelt; the US Army Chief of
Staff, Gen. George C. Marshall; and the Commanding General of US Army
Air Forces, Gen. Henry H. “Hap” Arnold. All promised to help him.
Wingate
hoped to return to Burma in 1944 with a larger force and asked the AAF
to resupply him by air and get his wounded out. Arnold agreed, but he
had more—much more—than that in mind. “We visualized an air commando
force, the first in military history,” Arnold said. “Large numbers of
Allied ground troops would be conveyed by aircraft deep into Burma, and
once there, they would be wholly supplied by air.”
To lead the
effort, Arnold sent for the two most capable lieutenant colonels he
could find. Philip G. Cochran was famous not only for his own
achievements but also because he was the model for Flip Corkin in Milton
Caniff’s “Terry and the Pirates” comic strip. John R. Alison had been a
fighter ace with the Fourteenth Air Force Flying Tigers in China; he
was widely regarded as one of the AAF’s best pilots.
Both of them
balked. Cochran said he did not want to go to some “offshoot side-alley
fight over in some jungle in Burma that doesn’t mean a damn thing.”
Alison, who had been selected to command a fighter group in England,
said, “I don’t think you need me, and I don’t want to go.”
Arnold
said this was not to be just a light-airplane operation. He intended to
give Wingate and his troops more than they had asked for, and to have
the AAF play a larger part in the operation than the British expected.
Cochran and Alison were going to Southeast Asia to develop and
demonstrate a new capability for airpower, he said.
Both Alison
and Cochran were promoted to the grade of colonel. They agreed that
Cochran would command and Alison was to serve as deputy. The
organization, dubbed the “Project 9 Task Force,” operated out of a room
in the Hay-Adams Hotel in downtown Washington and from an office in the
Pentagon. Alison concentrated on recruiting people and obtaining
equipment. Cochran went to London to confer with Wingate and Adm. Louis
Mountbatten, who would shortly become Supreme Allied Commander Southeast
Asia.
The project had top priority on everything, backed up as
necessary by Arnold’s chief of staff. Cochran and Alison were also freed
from the usual burdens of administration. Arnold told them, “To hell
with the paperwork. Go out and fight.” They took full advantage of the
dispensation.
They considered various ways to insert Wingate’s
force. Parachute drop would require training for the soldiers and would
not work for the mules the Chindits used for transport in the jungle.
Furthermore, Arnold’s scheme included building airfields, and the
construction equipment could not be parachuted in. Thus Cochran and
Alison built their insertion force around gliders.
The key to the
operation would be the Waco CG-4A Hadrian medium glider, which carried
13 passengers and their equipment or a jeep, a quarter-ton truck, or a
75 mm howitzer. The aircraft inventory that Alison pulled together
included 150 of these gliders, which would be towed behind C-47
transports with a 350-foot nylon line.
There were 348 aircraft in
all, including transports, gliders, P-51A fighters, B-25H medium
bombers, light “grasshopper” utility airplanes, and six experimental
helicopters. The force consisted of 523 men, all of them volunteers
except for Cochran and Alison.
Cochran went ahead to India,
arriving Nov. 13 with a small party. He found big trouble brewing when
he got to Delhi. Wingate, who did not know the extent of Arnold’s
intentions, told Cochran that the campaign had been canceled for lack of
transport aircraft.

This
landing site, dubbed “Piccadilly,” proved unusable for landing at the
last minute, forcing the entire group of gliders to land on “Broadway.”
Seen It, Done It
Mountbatten’s
staff doubted Cochran could deliver all that he promised, but
Mountbatten was convinced and ordered Wingate’s campaign to proceed.
Alison
finished up his work in the US and reached India on Christmas Eve. The
task force had been renamed the 5318th Provisional Air Unit, and by Jan.
1, all of the men and equipment were in the theater. They settled in at
two sod airstrips in the Imphal Valley about 100 miles west of the
India-Burma border, the transports and gliders at Lalaghat, and the
fighters and light aircraft at Hailakandi. Wingate’s headquarters was
close by at Sylhet.
The air commandos practiced glider tow with
men, equipment, and mules aboard. The mules were stubborn about getting
on the airplanes at first but they adjusted, and according to their
handlers, they even learned to bank in the turns.
For the main
insertion operation, the tow planes and the gliders would take off in
tandem from the airstrip, but the air commandos were also proficient in a
dramatic “snatch” variation in which low-flying aircraft could grab a
glider off the ground. The glider was hooked to a towline, which was
strung to a loop held 12 feet high between two poles.
A C-47
transport swept by at treetop level, trailing a catch line with a hook
on the end. The hook snagged the loop, the C-47 accelerated, and the
glider was yanked into the air. Inside the airplane, the line was
attached to a steel cable wound around a drum, which absorbed some of
the shock.
In January, the air commandos and the Chindits
performed 16 practice snatches. In one instance, 300 soldiers and their
mules were inserted by glider into a demonstration site and grabbed out
again. Wingate, who was aboard the first glider snatched, had a message
for the doubters: “Tell the RAF that I have not only seen it but I have
done it.”
In late February, the force practiced two covert
insertions with glider extraction. In one of them, a C-47 snatched two
gliders off a sandbar in the Chindwin River.
Command arrangements
were loose. The task force was assigned for administration and supply to
Tenth Air Force in India and was under the control of Mountbatten as
Allied commander in Southeast Asia. However, Cochran reported directly
to Arnold by cable and the chain of command did not strictly apply.
Cochran
had two letters in his pocket. One was personal from Arnold to
Mountbatten, saying the task force was exclusively for support of
Wingate’s force. The other was from Marshall, backing up Arnold on the
task force’s autonomy. Local commanders and in-theater organizations did
not like this arrangement, but they bowed, some more cheerfully than
others, to orders from Arnold and Marshall.
Wingate, now a major
general, had three Chindit brigades. One of them would march into Burma.
The other two would go in by air. Thirteen C-47s from Troop Carrier
Command supplemented the 13 the air commandos had. Troop Carrier Command
also provided pilots, but all of the aircraft commanders were from the
5318th PAU because of their glider towing experience.
The aerial
invasion of Burma was named Operation Thursday. It was set for March 5.
The gliders would go in first, land assault teams at two airfields, and
suppress any enemy forces found at sites. They would also carry
engineers and equipment to build airstrips for C-47s and British Dakotas
to land.
Two main landing sites, essentially large clearings, in
northern Burma were chosen. “Broadway” and “Piccadilly” were named for
streets in New York and London. A third backup site, “Chowringhee,” was
named for the main street in Calcutta.
Since only 26 C-47 tow
planes were available, some of the gliders would have to wait until the
transports returned from the first wave of landings. Each C-47 was to
pull two gliders. Forty gliders would go to Piccadilly, another 40 to
Broadway. American and British air forces would provide transports to
fly in troops after the initial glider landings.
On
Wingate’s orders, Cochran would remain at home base. Alison, however,
would fly one of the gliders and command the field at Piccadilly. Lt.
Col. Arvid E. Olson Jr., the executive officer, would be in command at
Broadway. Alison had never flown a glider before, but he made three
practice landings the day before the invasion and figured he was ready.

Cochran
(l) and Alison split command duties for Project 9 Task Force. Alison
concentrated on recruiting people and obtaining equipment; Cochran
conferred with Wingate and Mountbatten back in London.
Piccadilly Is Out
Wingate
had forbidden flights over the landing sites for fear of alerting the
Japanese. On the day of the mission, the air commando photo officer,
Capt. Charles L. Russhon, prevailed on Cochran to approve a
photoreconnaissance mission by a B-25. Cochran did not tell Wingate. The
aerial photos, rush processed, were delivered to the flight line at
Lalaghat where the gliders were getting ready to go and where Cochran,
Alison, and Wingate saw the pictures at about 5 p.m.
There was no
problem at Broadway, but hundreds of large tree trunks littered the
clearing at Piccadilly from one end to the other. The gliders could not
possibly land, and Wingate almost canceled the mission out of concern
that the Japanese had discovered the plan and blocked the landing site.
(It turned out that the trees had been left by Burmese loggers who used
the clearing to dry out their fresh-cut teak logs.)
After
conferring with Cochran and Alison, Wingate decided to go ahead with the
mission with all of the gliders going into Broadway.
The takeoff
was delayed by less than an hour. The first C-47, towing two gliders,
lifted at 6:12 p.m. The transports and gliders climbed out in wide
circles to gain enough altitude to cross the mountains, taking 45
minutes to reach 8,500 feet.
Broadway was 165 miles behind
Japanese lines, located in a river valley within striking distance of
the rail line that ran north from Mandalay. The first few takeoffs from
Lalaghat were without incident, but then problems developed. Towlines
broke. Some gliders had difficulty in takeoff. Some were lost. It was
later determined that the Chindits, who had been caught short of
supplies in the previous year’s operation, had stowed unauthorized
crates of rations and ammunition aboard the gliders, which were already
overloaded. Some of the gliders were carrying 2,000 pounds of extra
weight. Partway through the first wave, Cochran ordered that each C-47
pull one glider instead of two.
The first two gliders cut loose of
the tow plane and descended to Broadway, landing safely. The assault
teams bounded out on the dead run for the most logical places around the
clearing for the Japanese to have placed machine guns. They soon
determined that the site was unoccupied and fired a green flare to
indicate that they had not been fired upon. It was about 9 p.m.
The
lead glider towed by the second C-47 was flown by John Alison. His
command job at Piccadilly gone, he had joined the formation as backup
site commander to Olson, and it was good that he had done so. Olson’s
glider was among those that had gone down, and Alison would command the
field at Broadway. Alison cut loose of the tow plane and his glider
touched down smoothly at 70 miles an hour.

Wingate
(l) was an eccentric, but British leaders were impressed with his
determination to take the offensive. Here, he confers with Cochran.
By
luck, Alison had found one of the few unobstructed paths into Broadway.
The gliders behind him were not so fortunate. The site was not nearly
as clear as it had looked in the photos. “From the air it was impossible
for us to see large trenches overgrown with grass which crossed the
entire field,” Alison said. “The natives logged teak in this area and in
the wet season skidded the logs across the ground and down to the
river. Many years of this operation had completely rutted this area and
the ruts were covered with elephant grass and were not visible from the
air. They formed perfect glider traps, and there was no way of avoiding
them.
“The gliders began immediately to arrive overhead in large
numbers, and when a glider starts down there is no way to stop it. As
each glider would hit the trenches, the landing gears would come off,
and down the gliders would go in a heap. We tried to arrange the lights
to spread the gliders all over the field to avoid collisions, but this
was impossible. The gliders were coming in too fast to change their
directions, and glider after glider piled into each other in the landing
area.” The only available radio set was damaged in landing, but the
operator got it working long enough to dispatch a short message to
Cochran to hold the rest of the gliders.
Alison took charge of the
chaos and, incredibly, managed to get most of the men and equipment
down with limited casualties. That night, the gliders delivered 539 men,
three animals, and 65,972 pounds of stores, including bulldozers and
lighting apparatus. Of the 67 gliders that departed for Broadway, 32 got
there, 20 were lost en route, and 15 turned back.
Alison asked
his engineer how long it would take to make an airfield. “If I have it
done by this afternoon, will that be too late?” the young officer asked.
Within
24 hours, the engineers had cleared and prepared an airstrip 300 feet
by 5,000, and C-47s were coming in. Wingate was aboard the first one.
Alison, still acting as ringmaster, increased the rate of transports
into Broadway to 16 an hour. Impressed, Air Vice Marshal John E. A.
Baldwin, commander of the Third Tactical Air Force, said, “Nobody has
seen a transport operation until he has stood at Broadway under the
light of a Burma moon and watched Dakotas coming in and taking off in
opposite directions on a single strip at the rate of one takeoff or one
landing every three minutes.”
The Chindits spread out, tearing up
Japanese lines of communication and railroad tracks, destroying
supplies, and engaging the enemy in pitched battles. On the second
night, 12 gliders landed at the Chowringhee backup site, about 50 miles
south of Broadway. The first glider into Chowringhee was flown by Flight
Officer John L. Coogan—known to the American public as former child
star Jackie Coogan and ex-husband of actress Betty Grable.
Operation
Thursday ran for six days and six nights. During that time, 9,052
troops, 175 horses, 1,283 mules, and half a million pounds of supplies
were flown in by Troop Carrier Command, the RAF, and the 5318th—renamed
the 1st Air Commando Group by Arnold. Most of the deliveries were by the
C-47s. The gliders made 74 flights in all. The AAF generally regarded
the gliders as expendable, which was just as well. Their loss rate was
85 percent, mostly from the first night at Broadway. The only C-47 loss
was an aircraft that pranged into a water buffalo while landing at
Broadway at night.
Word From Arnold and Ike
The
air commandos continued to support Wingate with fighters and bombers
pounding the Japanese, light airplanes lifting Chindit casualties from
openings in the jungle, and other aircraft delivering and dropping
supplies and providing battlefield intelligence.
Where the
Chindits went, the air commandos went. Wingate made the rounds of the
battle area and jungle sites regularly, and it was nearly always Alison
who flew him. However, Alison was otherwise occupied on March 24 and a
different pilot was at the controls of Wingate’s airplane. A B-25H left
Broadway, made an intermediate stop at Imphal, and took off for
Wingate’s headquarters in India. It never got there. The airplane
crashed into the side of a mountain and exploded, killing all aboard.
Four
days later, Alison departed the theater in response to two radio
messages. The first said, “Report to me without delay,” and was signed
Arnold; the second said the same thing and was signed by Eisenhower.
With
approval from Arnold, Alison stopped briefly en route to confer with
Eisenhower, who was planning to use gliders in the D-Day invasion in
June and wanted to hear about the experience in Burma. Arnold assigned
Alison to organize more air commando groups, which he did, deploying
with one of them to the Southwest Pacific where he finished the war as
operations officer for Fifth Air Force.
The Chindit brigades
fought their last engagements in May 1944 and pulled out of Burma,
mining the Broadway site as they left. Monsoon rains made the sod
landing fields in the Imphal Valley unusable and Cochran pulled the air
commando group back to Central India. Cochran himself departed on May
20, 1944. He went first to Washington, where he conferred with Arnold,
and then on to Europe, where he served on Eisenhower’s staff.
Without
Wingate, enthusiasm for long-range penetration dwindled. US and British
armies in the Burma-India Theater returned to more traditional
strategies. The air commandos continued to provide support in Burma, but
there were no more big missions in the style of Operation Thursday.
Opinion was divided about the effectiveness of the Chindit campaign. In
death as in life, Wingate inspired both admirers and detractors.
However,
Operation Thursday had proved that a large force could be inserted and
sustained completely by air. Cochran and Alison are recognized as
founders of the air commandos, and appeared together at a program at
Hurlburt Field, Fla., in 1963, where they were honored as the
originators of Air Force special operations.

During
the six days of Operation Thursday, troops, supplies, and 1,283 mules
were flown into Burma by the air commandos. Most deliveries were made by
C-47s.
Cochran, in poor health, retired from the Air Force in
1945. He died in 1979. Alison had several careers: assistant secretary
of commerce for aeronautics, major general in the Air Force Reserve, and
industry executive as well as president, chairman of the board, and
longtime national director of the Air Force Association. Alison, who
will be 97 this month, is still active as a member of the AFA Senior
Leader Advisory Group, and tells a spellbinding story of that moonlit
night in Burma in 1944.
