The Chindits, officially known as Long Range Penetration Groups, were special operations units of the British and Indian armies which saw action in 1943–1944 during the Burma Campaign of World War II. Brigadier (later Major-General) Orde Wingate formed them for long-range penetration operations against the Imperial Japanese Army, especially attacking lines of communication deep behind Japanese lines.
The name Chindits is a corrupted form of Chinthe (Burmese: ခြင်္သေ့), the Burmese word for "lion".
Their operations featured long marches through extremely difficult terrain, undertaken by underfed troops often weakened by diseases such as malaria and dysentery. Controversy persists over the extremely high casualty rate and, despite results – such as the reallocation of an entire Japanese division and part of a second to deal with the Chindits – debate about the military value of special forces operations continued post-war.
During the East African Campaign of 1940–41, Wingate – under General Archibald Wavell, Commander-in-Chief of the Middle East Command – had begun to explore guerilla tactics, when he created and commanded a unit known as Gideon Force, composed of regular troops from Sudan and Ethiopia, as well as Ethiopean partisans. Gideon Force disrupted Italian supply lines and collected intelligence.
In 1942, after the disbandment of Gideon Force, Wavell – who had since been appointed Commander-in-Chief, India in New Delhi – requested the services of Wingate in Burma. It was intended that he would raise irregular forces to operate behind the Japanese lines, in a manner similar to Gideon Force. Wingate arrived in Burma in March 1942 and for two months, as Japanese forces advanced rapidly, toured the country developing his theories of long-range penetration, during the two months preceding the Japanese conquest of Burma. After returning to Delhi, he presented his proposals to Wavell.
Organisation and training
The first Chindit unit, the 77th Indian Infantry Brigade, was gradually formed in the area around Jhansi in the summer of 1942. Wingate took charge of the training of the troops in the jungles of central India during the rainy season. Half of the Chindits were British: the 13th Battalion, the King's Liverpool Regiment (nominally a second-line battalion, which contained a large number of older men) and men from the former Bush Warfare School in Burma, who were formed into 142 Commando Company. The other portion of the force consisted of the 3rd Battalion, the 2nd Gurkha Rifles (a battalion that had only just been raised) and the 2nd Battalion, the Burma Rifles (a composite unit formed from several depleted battalions of Burmese troops that had retreated into India in 1942).
Wingate trained this force as long-range penetration units that were to be supplied by stores parachuted or dropped from transport aircraft and were to use close air support as a substitute for heavy artillery. They would penetrate the jungle on foot, essentially relying on surprise through mobility to target enemy lines of communication (a tactic that the Japanese had previously used in 1942 to great effect against British forces in Malaya and Burma).
The standard brigade and battalion structures were abandoned. The force was instead formed into eight columns, each of which was organised as: an infantry rifle company (with nine Bren light machine guns and three 2-inch mortars); a support group with the heavy weapons (four Boys anti-tank rifles, two medium Vickers machine guns and two light anti-aircraft guns); a reconnaissance platoon from the Burma Rifles; and a sabotage group from 142 Commando Company. Small detachments from the Royal Air Force (equipped with radios to call in air support), Royal Corps of Signals and Royal Army Medical Corps were attached to the column headquarters. The heavy weapons, radios, reserve ammunition, and rations and other stores were carried on mules, which would also provide an emergency source of food once their loads had been depleted. With 57 mule handlers, each British column numbered 306 men (the Gurkha columns were slightly stronger, with 369 men).
Each man carried more than 72 pounds (33 kg) of equipment, which was proportionally more than the mules carrying the support weapons and other stores. This included a personal weapon, such as the SMLE rifle or Sten Gun, ammunition, grenades, a machete or Gurkha kukri knife, seven days' rations, groundsheet, change of uniform and other assorted items. Much of this load was carried in an Everest carrier, which was essentially a metal rucksack frame without a pack.
Shortly before the first operation, one column was broken up to bring the remaining seven up to full strength. Two or more columns were commanded by a group headquarters, which in turn was commanded by the brigade headquarters.
Operation Longcloth
The original intent had been to use the Chindits as a part of a larger offensive. When this offensive was cancelled, Wingate convinced General Wavell to send the Chindits into Burma anyway. Accordingly, on 8 February 1943, Operation Longcloth commenced and 3,000 Chindits, Wingate with them, began their march into Burma.
The Chindits crossed the Chindwin River on 13 February, and faced their first Japanese troops two days later. Two columns marched to the south, and received their air supply drops in broad daylight, to create an impression that they were to mount the main attack; reinforcing their unit's apparent threat with a man impersonating a British general. The Royal Air Force mounted aerial attacks on Japanese targets, to support this deception. These columns were to swing east at the beginning of March, to attack the main north-south railway, in areas south of the main force. One column successfully carried out demolitions along the railway, though the other was ambushed, losing half of its personnel, and returning to India.
Five further columns proceeded eastward. Two (those of Michael Calvert and Bernard Fergusson) proceeded towards the main north-south railway in Burma. On 4 March, Calvert's column reached the valley, and demolished the railway in 70 places. Fergusson arrived two days later, doing much the same. Despite these successes, however, the railway was only temporarily disabled, and resumed operation shortly afterward.
On many occasions, the Chindits could not take their wounded with them; some were left behind, in villages. Wingate had issued specific orders to leave behind all wounded (though these orders were not strictly followed). Since there were often no established paths in their jungle routes, many times they had to clear their own, with machetes, kukris (and, on one occasion, a commandeered elephant). Supply was delivered by air, using three Hudsons and three Dakotas of the RAF's 31 Squadron, operating from Agartala in eastern Bengal.
Once in Burma, Wingate repeatedly changed his plans, sometimes without informing all the column commanders. The majority of two of the columns marched back to India, after being ambushed by the Japanese, in separate actions. After the railway attacks, Wingate decided to cross his force over the Irrawaddy River. However, the area on the other side of the river turned out to be inhospitable to operations. Water was difficult to obtain and the combination of rivers with a good system of roads in the area allowed the Japanese to force the Chindits into a progressively smaller "box".
In late March, Wingate made the decision to withdraw the majority of the force, but sent orders to one of the columns to continue eastward. The operations had reached the range limit of air supply and prospects for new successful operations were low, given the Japanese pressure. The columns were generally left to make their own way back to India. On the journey back, the most difficult actions involved crossing back over the Irrawaddy River. The Japanese had observers and patrols all along the river bank and could quickly concentrate once an attempt at a crossing was detected. Gradually, all the columns broke up into small groups. Wingate's headquarters returned to India on its own ahead of most of the columns. Through the spring and even into the autumn of 1943, individual groups of men from the Chindits made their way back to India. The army did what they could for the men. In one case, an aeroplane was landed in an open area and wounded men were evacuated by air. Part of one column made it to China. Another body of men escaped into the far north of Burma. Others were captured or died.
By the end of April, after a three-month mission, the majority of the surviving Chindits had crossed the Chindwin river, having marched between 750–1,000 miles. Of the 3,000 men that had begun the operation, a third (818 men) had been killed, taken prisoner, or died of disease, and of the 2,182 men who returned, about 600 were too debilitated from their wounds or disease to return to active service. Of the remaining men, Wingate practically hand picked those few he would retain, while the rest were put back under the normal army command structure as part of their original battalions.
Interlude
Although British Army officers in India criticised the effectiveness of the Chindits (Japanese railway communications had been out of commission for less than a week), their effect on the morale of the Allied troops in India was refreshing, and they were given plenty of publicity.
Wingate wrote an operations report on returning to India, which was controversial for many reasons, including attacks on officers under his command. The report had a tendency to excuse any mistakes made by its author (Wingate), while making vicious attacks on other officers, often based on limited information. Eventually, through his political allies in London, a copy of the report was given to Winston Churchill, who was impressed and took Wingate with him to the Quebec Conference. His concepts for long-range penetration operations behind Japanese lines received official backing at high level, and he obtained substantial US support for his force. The US Army also began its own plans for the group that later became Merrill's Marauders.
As the members of the first expedition were making their way back to India, a second long range penetration unit, 111th Indian Infantry Brigade was being formed. Popularly known as The Leopards, the brigade was raised by General Wavell without the knowledge of Wingate, who was still in Burma and who was known to have a strong dislike for the Indian Army, its diverse troop formations, and its British officers in particular. Wavell personally selected the commander of 111th Brigade, Brigadier Joe Lentaigne.
Wavell intended to use two Chindit brigades alternately during 1944. While one brigade was operating behind Japanese lines for two to three months at a time, the other would be resting in India, while training for and planning the next operation. However, Wingate returned from Quebec with authority to implement far more ambitious plans for the second expedition, which required that the force be greatly expanded to a strength of six brigades. Wingate refused to use Indian Army units in this force, because he maintained that their training in long-range penetration techniques would take longer and their maintenance by air would be difficult due to the varied dietary requirements of different Gurkha and Indian castes and religions, although he had little choice but to accept 111th Brigade, and two Gurkha battalions in 77th brigade. Since large numbers of trained British infantry were required, three brigades (the 14th, 16th and 23rd) were added to the Chindits by breaking up the experienced British 70th Infantry Division, much against the wishes of Lieutenant General William Slim and other commanders, who wished to use the division in a conventional role. A sixth brigade was added to the force by taking a brigade (the 3rd (West African) Infantry Brigade) from the British 81st (West Africa) Division.
At Quebec, Wingate had also succeeded in obtaining a "private" air force for the Chindits, the 1st Air Commando Group, mainly consisting of USAAF aircraft. The Chindits were greatly encouraged by having aircraft on which they could call immediately for supply drops, casualty evacuation and air support. Other welcome American aid was the "K" Ration pack which, although it provided insufficient calories for prolonged active operations, was far better than the equivalent British or Indian ration pack.
The forces for the second Chindit operation were called Special Force, officially 3rd Indian Infantry Division, or Long Range Penetration Groups, but the nickname, the Chindits, had already stuck.
