The Chindits were unconventional warfare forces organized by Orde Wingate under British command for operations in Burma. They specialized in deep penetration of Japanese lines, with resupply provided from the air. Wavell, general officer commanding India in the early part of the war, had been sufficiently impressed by Wingate's activities during the campaign in Italian Somaliland that he authorized Wingate to raise a deep penetration force for the Far East. Wingate took charge of the Bush Warfare School, which had been forced to retreat to India with the rest of Burma Corps in early 1942.
Training at the school followed the typical special forces model, with emphasis on unarmed combat, jungle craft, physical training, ambush, and demolition. However, the Chindits differed from most special forces in that the men were not handpicked volunteers. Much of the original manpower came from 13 King's Liverpool Battalion and were older men who had previously served in garrison duty. Most of the rest were Gurkhas, who were normally excellent soldiers, but 3/2 Gurkha Rifles lacked experienced officers fluent in Gurkhalese. This may have been a deliberate choice by Wingate, who wished to show that ordinary soldiers could carry out deep penetration missions. One of Wingate's brigadiers, Michael "Mad Mike" Calvert, later said (Roberts 2011):
Most Europeans do not know what their bodies can stand; it is the mind and willpower which so often give way first. Most soldiers never realized that they could do the things they did ... One advantage of exceptionally heavy training is that it proves to a man what he can do and suffer. If you have marched thirty miles in a day, you can take twenty-five miles in your stride.
The first Chindit unit, 77
Indian Brigade, was
committed to battle on 8 February 1943 from its base in Imphal.
The timing was unfortunate, as the only offensive action
taken by regular forces against the Japanese
in Burma at the time was a
poorly planned and anemic advance into the Arakan region. A Chinese
offensive had been planned at
the same time as the Chindit operation, but had been called off.
Nevertheless, the operation went forward, even though the Japanese
could now easily protect their communications while
pursuing the Chindits. Wingate
apparently was eager to test his theories and to use his men at their
psychological peak, and he argued that the operation might have value
as a spoiling attack to throw off Japanese offensive plans in north Burma. Wavell seems to have had wholly unrealistic expectations of the expedition, believing it might so demoralize the Japanese (whom he consistently underestimated) that they might pull out of Burma entirely.
Notwithstanding the poor timing, the Chindits might have been able to operate effectively if they had stayed in the jungle; but Wingate pursued a grandiose scheme that took his columns across the Irrawady, where they would risk being caught in the open during the dry season. The expedition accordingly crossed the Chindwin on the night of 13 February 1943 in seven columns. The Northern Group, composed of Columns 3, 4, 5, 7, and 8 would cross at Tonhe and strike out for the rail line between Mandalay and Myitkyina. Meanwhile a Southern Group composed of Columns 1 and 2 would cross at Auktange further south, draw Japanese attention in that direction, then strike out for the Irrawady at Tagaung. After cutting the railway west of the Irrawady, the entire force would cross the river and join up to cut the railway from Mandalay to Lashio.
The route lay across the 4000' (1200m) Zibyu Range, the wide valley beyond, and the Mangin Range before reaching the Meza River valley that led to the Irrawady. The chief Japanese garrison between these ranges was at Pinlebu (95.368E 24.075N), and Wingate ordered 7 and 8 Columns to make a diversionary attack on the town. He then learned that the trail through the Mangin Range northeast of Pinlebu was unguarded, and 4 Column was sent to link up with 7 and 8 Columns and use the trail to head straight for the railway. However, 4 Column ran into a strong Japanese force and lost its communication equipment in the subsequent fire fight. Finding himself isolated with no way to contact Wingate, the column commander ordered his column to disperse and return to the Chindwin. Meanwhile 2 Column had been caught in the open while approaching the railway at Kyaikthin. Heavy mortar fire prompted its commander to order a retreat to a prearranged rendezvouz, but communications broke down and this column, too, was dispersed.
The fighting at Pinlebu provided enough of a distraction to allow 3 and 5 Columns to slip through to the railway at Nankan. A bomber raid on 5 March 1943 on nearby garrisons ensured minimal interference with the two columns the next day as they demolished three railway bridges and destroyed the track at numerous other locations. However, a chance encounter with a Japanese patrol left two men dead and six wounded, and the wounded had to be left behind. Only one survived the wrath of the Japanese and local Burmese. The two columns then moved on to cross the Irrawady, but 5 Column was fired on by the Japanese while crossing the river at Tigyaing. 6 Column was also caught as they crossed, but the rearguard held off the Japanese until the crossing was complete. Their wounded were also left behind, with a note reminding the Japanese of the traditional Bushido ethic of humanity, and these wounded were properly cared for.
The Japanese responded vigorously to the penetration. 55 Regiment (18 Division) west of the Zibyu Range and 215 Regiment (33 Division) to the south had each made contact with Chindit columns, and both began pursuing the Chindits towards the Irrawady. It was a battalion of 55 Regiment that caught 6 Column at Tigyaing. The
Japanese soon realized that the Chindits were operating without
conventional lines of supply, decided they were a significant threat,
and committed both 18 and 33 Divisions to destroying Wingate's force. After it became clear the Chindits were continuing east beyond the Irrawady, 56 Division was brought in as well. Wingate's brigade now had the undivided attention of three Japanese divisions in open country during the dry season with two major rivers between his force and his base.
The outcome was that Wingate was forced by 25 March 1943 to order his columns to split up and make their way back to India as best they could. Plans to blow up the viaduct at Gokteik were abandoned, but not before Calvert ambushed a large Japanese patrol outside Myitson, killing 100 Japanese for the loss of a single man. A proposal to move north into country with a friendlier population was rejected because it would take the Chindits out of air supply range. An attempt to resupply by air near Baw failed when surprise was given away and a pitched battle ensued. The officer responsible for giving away surprise was cashiered and finished the expedition as a private. The dispersed Chindits had to make their way home through three enemy picket lines, along the Irrawady, the Chindwin, and the Mu Valley between them. Seriously wounded men were sometimes given a lethal dose of morphine rather than leave them to the Japanese (Hastings 2011):
I had a wounded Gurkha, shot to bits in great pain, and dying. After agonizing for a bit, I gave him a lethal dose of morphia ... The Gurkhas were amazing, they just accepted it ... To my horror I found another very seriously wounded Gurkha. I said, "I've just had to do it." George looked at me as if to say "You do it again." I protested, "There's no way I'm going to do it twice." He gave the chap a lethal dose.
the end of May the bulk of the surviving Chindits were back at Imphal,
while a few stragglers escaped through Fort Hertz to the north or even into China.
The first Chindit expedition merely inconvenienced the Japanese while suffering heavy casualties. Of the 3000 men who crossed the Chindwin in February, 2182 made it back to India by June. Some 450 had been killed in action, 430 were taken prisoner by the Japanese, and 120 men of the Burma Rifles were allowed to disband and return to their homes. Even one of Wingate's best column commanders, Major Bernard Fergusson (5 Column), admitted that the operation had achieved (Roberts 2011):
... not much that was tangible. What there was became distorted in the glare of publicity soon after our return. We blew up bits of railway, which did not take long to repair; we gathered some useful Intelligence; we distracted the Japanese from some minor operations and possibly from some bigger ones; we killed a few hundreds of an enemy which numbers eighty millions; we proved that it was feasible to maintain a force by supply dropping alone.
But Wingate was a sufficiently charismatic visionary that the raid was seen as some kind of great military accomplishment. Even Slim, who was privately highly critical of the whole concept, claimed that the Chindits had been very good for morale in the Indian Army, stating that "for this reason alone, Wingate's raid was worth all the hardship and sacrifice his men endured" (Lewin 1976). Churchill himself fell under the charm, and considerable additional manpower, including the whole of 70 Division (Symes), was committed to new Chindit formations. Eventually five additional Chindit brigades were raised: 3 West African, 14, 16, and 23 British, and 111 Indian Brigades. Each was composed of four battalions, and the entire Special Force was designated 3 Indian Division as cover. Inspired by the British example, the Americans raised their own irregular force, 5307 Composite Unit, who rejected their official designation ("disgustingly like a street address in Los Angeles") in favor of "Merrill's Marauders." There is reason to suspect that the British viewed the Chindit operations as a way to satisfy American demands for action in Burma without committing large formations to a theater in which they had little interest.
After Wingate won over "Hap" Arnold at the Quebec conference, the Chindits were given their own air component, 1 Air Commando Group, consisting of 13 C-47 Dakotas, 12 C-46 Commandos, 12 B-25 Mitchells, 30 P-51 Mustangs, 100 L-5 Sentinels, and six R-4 Hoverfly helicopters. The light aircraft and helicopters were of particular significance to both command and control and morale,
since they provided a way to move commanders around quickly and to
evacuate the wounded, who had to be left behind during LOINCLOTH.
Wingate's original concept of deep penetration raids became more
grandiose with time. He began to see the Chindits, not as auxiliary
forces devoted to cutting enemy communications while avoiding pitched
battles, but as the main offensive force to which the regular divisions
of 14 Army would themselves be little more than auxiliaries. Wingate eventually developed a "stronghold" doctrine (Royle 2002):
The stronghold is a muccan (ph) overlooking a kid tied up to entice the Japanese tiger. The stronghold is an asylum for long range penetration for wounded. The stronghold is a magazine of stores. The stronghold is a defended airstrip. The stronghold is an administration centre for loyal inhabitants. The stronghold is an orbit around which columns of the Brigade circulate. It is suitably placed with reference to the main objective of the Brigade. The stronghold is a base for light planes operating with columns on the main objective.
A second series of
expeditions began with the departure on 5 February 1944 of 16 Long
Range Penetration Brigade (LRP) from Ledo
marching south towards "Aberdeen", a site selected for its suitability
construction of a small airstrip for resupply. Stilwell
was leading a force of three American-trained Chinese divisions from
Ledo across the Pangsau Pass into the inhospitable Hukawng Valley. From
there he planned to advance to the railroad east of Myitkyina, building a road behind him as he advanced, with the objective of joining hands with a second Chinese force from Yunnan
and restoring land communications with China. Wingate's men were to
support Stilwell by severing the lines of communication of the
defending 18 and 56 Divisions.
16 LRP took almost a month to cross the rugged mountains between Ledo and the Chindwin, which they crossed at Singaling Hkamti (95.700E 26.002N) on 3 March. Two days later, 77 Indian Brigade began its air landings at "Broadway". Plans for a third stronghold, "Picadilly", were dropped when the planned site for the air landings was found to be covered with log obstacles. Wingate worried that the Japanese had somehow gotten wind of their plans, and he had to be persuaded by Slim to continue the Broadway air landings. As it turned out, the obstacles were felled trees left by civilian foresters and had nothing to do with the Japanese.
The first gliders into
"Broadway" discovered that there were two trees on the main runway and
a number of ditches, and of the 61 gliders that took off that night,
only 35 made it to the strip. Seventeen came down in Assam and six
landed in Japanese-controlled areas of Burma. However, two bulldozers
had made it in, these cleared the strip, and by the next evening the
first of 63 Dakotas began to fly in, led personally by Old. On 6 March 111 Brigade began flying in to "Chowringhee". Eventually some 600 sorties brought a total of 9000 troops with 1400 pack animals and artillery.
On 8 March the Japanese began their long-planned U-Go
the objective of seizing Imphal,
Kohima, and Dimapur, isolating
forces in northeast Assam
and opening the road to India.
The British had hoped that the Chindit activity would interfere with
Japanese offensive, but the Japanese were relying on capturing
British dumps to resupply and Mutaguchi did not initially consider the
Chindits a serious threat. The senior Japanese air commander in Burma, Tazoe Noboru, had
anticipated a Chindit airborne operation based on the airstrips the
British had constructed during LOINCLOTH and on intelligence that the
British were construction large numbers of gliders at Calcutta.
However, he could not persuade Mutaguchi to deploy more than a small
force to contain the Chindits, whom Mutaguchi regarded as "a mouse in a
bag" (Allen 1984).
"Chowringhee" was raided by 20 fighters and two light bombers on 10 March 1944 and "Broadway" was raided by 55 fighters and three light bombers on 13 March. The Japanese also brought in some 11 battalions under 24 Independent Mixed Brigade (Hayashi) to counter the twenty battalions of Chindits.
Attack on Indaw. Mutaguchi soon deduced that the main Chindit target was the massive supply dump at Indaw, and this was reinforced on 10 March with two infantry companies and on 15 march with a full battalion from 51 Regiment. The two companies attacked attacked Calvert's railroad block at "White City" on 17 March and were cut to ribbons in a desperate night attack. On 21 March a battalion from 114 Regiment was repulsed at "Broadway" with heavy casualties. By this time the Japanese had revised their initial estimate of 1000 Chindits to a much more accurate figure of 10,000.
The attack on Indaw was a failure. The main attack force, 16 Brigade, was supposed to be in position by 15 March, but the march from Ledo proved too difficult, and it was not until 20 March that 16 Brigade reached its planned stronghold location at "Aberdeen". Here Wingate met the brigade commander, Fergusson, and ordered him to proceed at once to attack Indaw and seize the airfield there. Wingate's intentions were never clarified before his death, but Fergusson had the impression that Wingate meant to expand THURSDAY by flying in a division of regular Indian troops (26 Indian Division). Fergusson also thought 14 Brigade would be supporting his attack, but Wingate had already ordered 14 Brigade to move southwest and cut the supply lines from Indaw to Homalin.
Because Wingate had stressed the importance of reaching Indaw before the
Japanese could reinforce, Fergusson stepped off to attack the town
almost immediately, without taking time to rest his exhausted columns.
It was the peak of the dry season and there was no water between
Aberdeen and Lake Indaw. 45 Column was ordered to take Thetkegyin on
the north shore of the lake but found the village stoutly defended by
the Japanese. 17 Column was almost at the airfield before making
contact with the Japanese, and took position in a streambed that
provided a water supply, but after repelling counterattacks for three
days Fergusson was compelled to withdraw his force back to "Aberdeen."
The attempt to take Indaw was not entirely fruitless: The Chindits
discovered the massive Japanese supply dumps in the area and called in
a bombing raid that destroyed most of the supplies earmarked for 18 Division.
Death of Wingate. On 24 March Wingate was killed in an air crash. Command of the Chindits was taken over by the senior brigade commander, Lentaigne, and came under the overall control of Stilwell. Both were controversial decisions. Of all Wingate's brigadiers, Lentaigne was the most skeptical of the entire concept of deep penetration, and Stilwell was skeptical he could exert any real command authority over the Chindits. Lentaigne immediately made a number of decisions that badly hurt the Chindit operations.
Slim wished the Chindits to concentrate around Kalewa (94.301E 23.201N) to cut the supply lines to 15 Army. However,
two of the Chindit brigades were already in battle and could not easily
break contact with the Japanese; abandoning "White City" would reopen
the railroad to north Burma and 18 Division; and the approach
to Kalewa invited a Japanese ambush. A compromise in which the two
as-yet unengaged Chindit brigades would move towards the Chindwin was
appproved by Lentaigne but then countermanded by Slim, who recommended
the Chindits shift to Stilwell's control.
77 Indian Brigade at "White City" had thrown back a second Japanese assault on 6-11 April that cost the Japanese an estimated 3000 casualties. With roughly seven battalions against Hayashi's eight, the brigade commander, Calvert, had every confidence he could hold the position indefinitely. However, on 8 May, Lentaigne ordered Calvert to abandon the block at "White City" and reestablish a blocking position at "Blackpool", closer to the front line. Lentaigne wanted to concentrate his forces to ensure the rail corridor could be held through the monsoon, but was unwise to abandon so strong a position.
"Blackpool" was to be held by 111 Indian Brigade while 14 and 77 Indian Brigade acted as a floating column operating in the direction of Mogaung (96.940E 25.303N). The exhausted 16 Brigade had already been evacuated and 23 Brigade had been redeployed behind the Chindwin to cut 15 Army's supply lines to Kohima. The Chindits were promised that when Mogaung fell to the Chinese, the campaign would be over and the Chindits would be evacuated back to India. Meanwhile the Japanese had responded to the attack by created a new headquarters, 33 Army (Honda), to deal with Stilwell and the Chindits.
The Chinese had paused again after reached the Mogaung Valley on 19 March 1944, buy on 19 May they began advancing again. Sun's 112 Regiment outflanked 18 Division and took Kamaing (96.711E 25.522N), cutting off 18 Division. The Japanese threw 53 Division (Takeda) into the effort to break the block, but the Chinese could not be dislodged and 18 Division was forced to withdraw, with just half its original strength escaping the Chinese grip.
Meanwhile "Blackpool" had come under heavy attack. Lentaigne had
placed the new base too close to the Japanese front lines, and it came
under heavy artillery fire almost as soon as it was established.A week later 128 Regiment
joined the attack, 14 Brigade never arrived to reinforce 111 Indian
Brigade, and by 25 May the stronghold had to be abandoned. Stilwell
then earned the everlasting hatred of most of the Chindits by ordering
the survivors of 77 and 111 Indian Brigades to take Mogaung. The
Chindits were outnumbered two to one by the garrison, and although they
took the town on 27 June, their casualties were so heavy (about 50%)
that they were finished as a fighting force. By 27 August 1944 the last of
the Chindits had been evacuated back to India.
Outcome. The Japanese later admitted that, in addition to
pinpointing the dumps at Indaw for destruction by air strike, the
Chindits interfered so seriously with the Japanese lines of
communication that neither 15 nor 33 Divisions
facing Imphal received any supplies to supplement their original 25-day
allocation. Having failed to capture the British supplies
on which they had planned to sustain their offensive, the Japanese were
forced back and the route to Imphal from Dimapur reopened. Chindit
units also interfered with the lines of communication of 18 Division as it
to hold Myitkyina against
Stilwell's Chinese forces, and
hindered the reinforcement of northeast Burma by 49 Division.
Of the 11 battalions the Japanes brought in against the Chindits, only one was drawn from 15 Army, the rest being drawn from garrisons around Burma. This suggests that the Chindit foray diverted more Allied than Japanese troops from the main effort before Imphal. On the other hand, Mutaguchi later stated that "The Chindit invasions did not stop our plans to attack, but they did have a decisive effect on these operations and they drew off the whole of 53 Division and parts of 15 Division, one regiment of which would have turned the tables at Kohima" (Roberts 2011).
WIth the opening of the Ledo Road and the collapse of U-Go, the British finally felt in a position to mount a conventional counteroffensive into Burma. This largely eliminated the need for special forces supplied by air, particularly since the air transport was now needed to support the regular forces. As a result, the Chindits were disbanded.
Wingate's "stronghold" doctrine was heavily criticized after the war. However, something like it was tried again by the French in Indochina in 1954 at Dien Bien Phu.
The result was a crushing defeat for the French. On the other hand, the
battle of Khe Sanh in Vietnam in 1968 used similar tactics but was more
successful, though victory was achieved only through massive use of
superior firepower in the form of air and artillery support. The terrain at Khe Sanh was also more favorable for the defenders.
