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, 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. The new Chindit force commenced training in
Gwalior. Men were trained in crossing rivers,
demolitions and
bivouacking. Calvert and Fergusson, both newly promoted to Brigadier, took command of two of the brigades, and were responsible for much of the training program and the development of tactical planning. Wingate himself was absent for much of the training period, first being out of the country to attend the Quebec Conference and then struck ill with typhoid from drinking bad water in North Africa on his return.
Plans The plans for the second Chindit operation went through many revisions. The methods of the new Long Range Penetration force in 1944 differed from those of 1943. Wingate had decided on a strategy of creating fortified bases behind the Japanese lines, which would then send out raiding columns over short distances. This change was in part forced on him by strengthened Japanese patrols along the Burmese frontier, making a repeat of the successful infiltration in 1943 unlikely. In an imaginative move prompted by Colonel
Philip Cochran's assurance that he could transport both troops and supplies by glider, Wingate arranged for the bulk of the force to enter Burma by air, greatly accelerating the force's ability to reach its target objectives. Advance units would land in gliders in preselected open fields in Burma, and prepare them for large-scale landings by transport aircraft. The lavish air support provided by Colonels Cochran and
Alison of the 1st Air Commando Group proved critical to the success of the operation. Wingate also had plans for a general uprising of the
Kachin population of Northern Burma. He fought over these plans with the leadership of
Force 136 (an organisation set up to liaise with resistance forces in Japanese-occupied countries), which was concerned that a premature uprising of the Kachins without a permanent British military presence would lead to their slaughter by the Japanese at the end of operations. Force 136 also had their own plans for a rising to be coordinated with the arrival of the regular army in Burma. Wingate was eventually convinced to scale back his original plans. Further complicating relations between the organisations were orders issued by Wingate to the commander of Dah Force (a British-led force of Kachin irregulars attached to the Chindits) not to coordinate operations with Force 136 for security reasons. During the last months of 1943, planning was conducted to carry out the strategy for India as originally determined at the Quebec Conference. In November, the overall plan for the dry season campaign of 1944 determined by
South East Asia Command focused on the use of the Chindits in the reconquest of northern Burma. These plans were approved by the
Combined Chiefs of Staff at the
Cairo Conference and although other offensives in Burma were scaled back or cancelled, Stilwell's Northern Front offensive with the Chindits' participation survived the cuts. The uncertainty of the plans nevertheless meant that the plans and contingency plans for the use of the Chindits repeatedly changed up to the very start of operations. The Chindits were assigned the task of helping the forces of
Joseph Stilwell push the
Ledo Road through northern Burma to link up with the
Burma Road and re-establish an overland supply route to China, by mounting a long range penetration operation behind the Japanese opposing his forces on the Northern Front. It had originally been intended that the IV Corps would attack on the Central Front and cross the Chindwin to tie up Japanese forces which could otherwise be used to aid the Northern Front. As the Japanese launched their own attack on the Central Front this advance did not take place, but it still meant that most Japanese forces were engaged on the Central Front and were not available to reinforce the Japanese 18th Division on the Northern Front. The Japanese offensive on the Central Front resulted in further proposals and refinements of the plans for the Chindits. ==Operation Thursday== , 3rd West African Brigade (Thunder), board an RAF
Dakota On 5 February 1944, Fergusson's 16th Brigade left
Ledo for Burma. They avoided Japanese forces by traversing exceptionally difficult terrain. The rest of the Brigades were brought in by air to create fortified bases with airstrips. Three landing zones, codenamed
Piccadilly,
Broadway and
Chowringhee, were selected. Calvert's 77th Brigade prepared to fly by
Hadrian glider into
Piccadilly on the night of 5 March. A last-minute aerial reconnaissance revealed
Piccadilly to be covered with logs, making landing impossible. In some accounts of the incident, Wingate insisted that the operation had been betrayed and that the other landing zones would be ambushed. To proceed would be "murder". Slim accepted the responsibility of ordering a willing Calvert to proceed with the operation, using
Broadway instead. While
Piccadilly had already been used to evacuate casualties during the first Chindit operation in 1943,
Broadway had to be selected from the results of aerial reconnaissance. It turned out to be a poor landing ground and there were many casualties in crash landings, but Calvert's men were just able to make the strip fit to take transport aircraft the next day. Chindit gliders also landed on
Chowringhee the next day, without opposition. It was later revealed that the logs on
Piccadilly had been placed there to dry by Burmese teak loggers. The real problem was the failure to maintain continuous observation of the landing zones (e.g. by high-flying
Spitfire photo-reconnaissance aircraft) before the forces were deployed. Over the next week, 600 sorties by
Dakota transport aircraft transferred 9,000 men to the landing zones.
Chowringhee was abandoned once the fly-in was completed, but
Broadway was held with a garrison which included field artillery, anti-aircraft guns and even a detachment of six Mk.VIII Spitfires of No.81 Squadron RAF from 12 March to 17 March. On 17 March they were attacked during take-off by Japanese Ki-43 'Oscars'. S/L William 'Babe' Whitamore and F/O
Alan M Peart managed to get airborne, with both shooting down one 'Oscar' each. Whitamore was shot down and killed but Peart survived for over half an hour, holding off over 20 enemy fighters. The remaining Spitfires were destroyed on the ground for the loss of another pilot, F/Lt Coulter. Peart flew back to Kangla the same day in his damaged Spitfire (FL-E JF818) and reported the action. The detachment was duly ended by
AVM Stanley Vincent, the CO of No. 221 Group. After this, most of the tired 16th Brigade were flown out.
Change of command On 24 March, Wingate flew to
Imphal to confer with air force commanders. On the return journey, the USAAF
B-25 bomber in which he was flying is believed to have flown into a thunderstorm and crashed in the jungle-covered mountains. All aboard were killed. Slim, the commander of the Fourteenth Army which had loose operational control over Special Force, selected Brigadier Lentaigne to be Wingate's replacement after conferring with Brigadier Derek Tulloch, Wingate's Chief of Staff. Lentaigne was judged to be the most balanced and experienced commander in the force; he had been an instructor at the Staff College at
Quetta, had led a Gurkha battalion with distinction during the gruelling retreat from Burma in 1942 and had commanded a Chindit brigade in the field (albeit for only a few weeks, but none of the other brigade commanders had more experience). As an officer of Gurkha troops, he had a similar outlook and background to Slim. The other Chindit brigade commanders were unknown quantities, mostly without staff qualifications, some of whom had never even commanded a battalion-sized unit in combat before 1944, and Wingate's staff officers lacked the necessary combat experience. The force's second-in-command, Major General
George William Symes, was bypassed by Slim and formally protested and asked to be relieved. In selecting Lentaigne, Slim did not take into account the tensions between those Chindit commanders and staff who were closely associated with Wingate, and Lentaigne, who had a classical "line" officer's background and had been critical of Wingate's methods and techniques.
The move north Several major changes were made at the highest level. Much of the air support was diverted to the critical battles of
Imphal and
Kohima, where troops were cut off and could only be resupplied by air. 23rd Brigade, yet to fly in, was also despatched to
Kohima. Those Chindits already operating in Burma were formally subordinated to General Joseph Stilwell, who ordered the Chindits to abandon their dispersed operations around Indaw, and concentrate on interdicting the supply lines to the Japanese forces opposing his
Northern Combat Area Command. In April, Lentaigne ordered the main body of 111 Brigade west of the Irrawaddy, now commanded by
John Masters, to move north and build a new stronghold, codenamed
Blackpool, which would block the railway and main road at
Hopin, south of
Mogaung. Calvert was ordered to abandon
White City and
Broadway and move north to support Masters. Calvert was opposed to this, as his brigade had successfully held these two strongholds for months. Stilwell also feared that abandoning
White City would allow Japanese reinforcements to move north. However, Lentaigne insisted that the Chindit brigades were too far apart to support each other, and that the airstrips at
White City and
Broadway would be unusable during the
monsoon. Masters's force established
Blackpool on 8 May and was almost immediately engaged in fierce fighting. Whereas
White City had been deep in the Japanese rear, its defenders had had plenty of time to prepare their defences and its attackers had been a mixed bag of detachments from several formations,
Blackpool was close to the Japanese northern front, and was immediately attacked by Japanese troops with heavy artillery support. As Calvert and Stilwell had feared, abandoning
White City had allowed the
Japanese 53rd Division to move north from Indaw. A heavy attack against
Blackpool was repulsed on 17 May, but a second attack on 24 May captured vital positions inside the defences. Because the monsoon had broken and heavy rain made movement in the jungle very difficult, neither Calvert nor Brodie's 14th Brigade could help Masters. Finally, Masters had to abandon
Blackpool on 25 May, because the men were exhausted after 17 days of continual combat. Nineteen Allied soldiers, who were so badly injured as to be beyond hope of recovery and could not be moved, were shot by the medical orderlies and hidden in heavy stands of bamboo.
Final operations giving orders after the capture of Mogaung On 17 May, Slim had formally handed control of the Chindits to Stilwell. Stilwell insisted that the Chindits capture several well-defended Japanese positions. The Chindits had no support from tanks or artillery and this led to heavier casualties than before. According to David Rooney, the Chindits were misused under Stillwell's command and suffered heavy casualties undertaking roles for which they were neither trained nor equipped. From 6 June to 27 June, Calvert's 77th Brigade took Mogaung and suffered 800 casualties; 50 per cent of the brigade's men involved in the operation. Fearing that they would then be ordered to join the
siege of Myitkyina, Calvert handed Mogaung over to
Force X, shut down his radios and retreated to
Kamaing, where Stilwell had his headquarters. A court-martial was likely until Stilwell and Calvert met in person, and Stilwell finally appreciated the conditions under which the Chindits had been operating. 111 Brigade, after resting, was ordered to capture a hill south west of Mogaung, known as Point 2171. It did so but was now utterly exhausted. Most of the men were suffering from
malaria,
dysentery and
malnutrition. On 8 July, at the insistence of the Supreme Commander, Admiral
Louis Mountbatten, doctors examined the brigade. Of the 2,200 men present from four and a half battalions, only 119 were declared fit. The brigade was evacuated, although Masters sarcastically kept the fit men, "111 Company", in the field until 1 August. The portion of 111 Brigade east of the Irrawaddy were known as
Morris Force, after its commander, Lieutenant-Colonel J. R. "Jumbo" Morris. They had spent several months harassing Japanese traffic from
Bhamo to Myitkyina. They had then attempted to complete the encirclement of Myitkyina. Stilwell was angered that they were unable to do so but Slim pointed out that Stilwell's Chinese troops (numbering 5,500) had also failed. By 14 July, Morris Force was down to three platoons. A week later, they only had 25 men fit for duty. Morris Force was evacuated about the same time as the 77th Brigade. The 14th Brigade and the 3rd West African Brigade remained in action, assisting the newly arrived
36th Infantry Division in its advance down the "Railway Valley" south of Mogaung. Finally, they were relieved and withdrawn, starting on 17 August. The last Chindit left Burma on 27 August 1944.
Kohima 23rd Brigade, which had been diverted from the main Chindit campaign, nevertheless acted as a long range penetration unit behind the Japanese fighting at Kohima. From April to June 1944, they marched long distances through the Naga hills, mostly in monsoon weather which made movement very difficult. They contributed in large measure to the starvation of the Japanese at Kohima, the decisive factor in that battle. Although not engaged in major battles, they accounted for large numbers of Japanese stragglers and foragers, suffering 158 battle casualties themselves. ==Disbanded==
