20th Indian Infantry Division

20th Indian Infantry Division was an infantry formation of the British Indian Army raised during World War II in 1942 for operations in the Burma Campaign and Southeast Asia Command. The division served under formations including Eastern Army (India), XXXIII Indian Corps, and later elements of Fourteenth Army during major engagements around Imphal, Kohima, and the advance into Central Burma. It played a role in combined operations alongside formations such as the 14th Army (United Kingdom), units of the Royal Air Force, and Allied corps in the South East Asian Theatre.

Formation and Early History

The division was formed in 1942 from cadres drawn from established brigades and depot units stationed across India, including battalions recently engaged in the North African campaign and garrison duties in East Africa and the Middle East. Initial formation and training took place in staging areas such as Rangoon hinterlands, forward bases near Chittagong, and training camps influenced by doctrines from British Expeditionary Force (World War II), with staff officers who had served under commanders like William Slim and staff trained at institutions echoing lessons from the Aden and Malaya theatres. Early history saw rapid expansion, integration of support elements, and adaptation to jungle tactics drawn from experiences in the Burma Campaign and techniques promoted by the Chindits and airborne advisors linked to Allied Airborne Forces.

Organization and Order of Battle

The division's core comprised three infantry brigades, divisional artillery, engineers, reconnaissance, signals, medical, and logistics units, organized broadly on patterns similar to other contemporaneous divisions such as 17th Indian Infantry Division, 23rd Indian Division, and 7th Indian Infantry Division. Infantry battalions were drawn from regiments including the Rajput Regiment, Punjabi Regiment, Mahar Regiment, Gurkha regiments, and the Royal Sussex Regiment, supported by artillery from units like the Indian Army Ordnance Corps and Royal Artillery batteries formerly attached to formations like Eastern Command (India). Engineers included companies from the Royal Bombay Sappers and Miners and Madras Sappers, with signals provided by formations influenced by the Royal Corps of Signals. Logistic support was coordinated alongside elements of the Royal Indian Army Service Corps and medical services from the Indian Medical Service.

World War II Service and Campaigns

Deployed into active operations in the Burma Campaign, the division participated in offensive and defensive phases during the Imphal campaign, fighting in terrain linked to the Naga Hills and approaches to Manipur. It took part in actions coordinated with corps and army-level operations such as those under XXXIII Corps (United Kingdom), advancing in concert with formations like 36th British Division and confronting Imperial Japanese Army units including divisions from the Twenty-Eighth Army (Japan). The division was engaged in river crossings and jungle advances that invoked combined-arms support from the Royal Air Force and Royal Navy elements for riverine logistics reminiscent of operations near Irrawaddy River and during drives toward Meiktila and Rangoon. Campaigns saw cooperation with long-range penetration forces modeled on the Chindits and liaison with Allied commands such as South East Asia Command under leaders tied to multinational planning processes like the Pacific War coordination at higher strategy levels. The division's operational timeline intersected with major battles and offensives including stages of the Battle of Kohima, culminating in the advance into central Burmese railheads and link-ups that contributed to surrender negotiations with remnants of Japanese formations.

Commanders and Leadership

Command appointments reflected senior officers experienced in colonial and continental theatres, with leadership roles filled by officers who had served under or alongside distinguished commanders such as William Slim and Philip Christison. Senior staff officers were often veterans from formations including Indian XV Corps and British Home Forces, bringing doctrinal influences from campaigns like the Western Desert Campaign and administrative experiences shaped by institutions such as the India Office. Brigade commanders frequently had prior commands in brigades like 99th Indian Brigade and staff college attachments to establishments linked to the Staff College, Camberley and Imperial Defence College.

Postwar Disbandment and Legacy

After the end of World War II and the collapse of Japanese resistance in Southeast Asia, the division was progressively disbanded amid postwar redeployments that involved demobilization procedures administered through headquarters like GHQ India and the South East Asia Command transition offices. Personnel were repatriated to regiments such as the Gurkha regiments and reabsorbed into peacetime establishments tied to successor organisations including the Indian Army after Indian independence movement outcomes and partition processes overseen by administrations like the British Raj transition. The division's legacy persists in regimental histories, battle honours recorded alongside campaigns like Burma Campaign 1944–45, and in doctrinal studies that influenced postwar jungle warfare training at institutions connected to the School of Infantry (India) and commemorative projects by veterans' associations and regimental museums.
