The Indian III Corps was the primary ground formation that took part in the Malayan Campaign in 1942. It was commanded by Lieutenant-GeneralSir Lewis "Piggy" Heath. Indian III Corps was formed in mid-1941 as part of the Malaya Command when the increase in tension in the Far East necessitated the dispatch of large reinforcements to the area to deter Japan. On 7 December 1941 the Corps consisted of the Indian 9th Infantry Division, commanded by Major-General Arthur Edward Barstow, the Indian 11th Infantry Division, commanded by Major-General David Murray-Lyon, a lines of communication Area, and the Penang Fortress. Due to the rapid expansion of the British Indian Army, many of the formations in the Indian divisions were ill-trained and lacked large enough cadres of experienced troops. The British had plans – Operation Matador and Operation Krohcol – to move forward into the south of Siam to forestall Japanese advances. However, lack of forewarning, combined with caution over upsetting Japan needlessly with precipitate actions, prevented the plans from being implemented. This put the garrison on the defensive, a position from which it never recovered. III Corps was pushed down the Malayan peninsula by Japanese units, who employed novel tactics. When confronted with an Allied strong point on a road, the Japanese troops would leave a screen in front of the position, and then send infiltrators round through the jungle to outflank the position. Having been surrounded, positions were usually relatively easy to take. III Corps and the rest of the Allied land forces were pushed back to Singapore itself by February 1942. There they endured a short siege before the island surrendered at the direction of Lieutenant-General Arthur Ernest Percival. Some of the prisoners taken from Indian III Corps subsequently joined the Indian National Army.
Post independence
After the independence of India, a new III Corps was raised by the Indian Army in the 1980s. It is based at Dimapur in north east India, and contains mountain formations and is tasked for use in any future Indian war againstChina. Jane's estimates that it consists of:
56th Mountain Division headquartered at Zakhama, Nagaland Reportedly operational October 2009. Includes 46 Brigade and the 22 Brigade, though 22 Brigade may shift to 2nd Mountain Division.
57th Mountain Division headquartered at Leimakhong. Raised in 1966 for counterinsurgency operations in Mizoram. Until 1990 headquartered at Aizawi with III Corps. Globalsecurity.org reports the 57 Mountain Division headquarters are at Masimpur near Silchar. The formation and units of 57 Mountain Division are deployed in some of the remotest corner of Manipur and Indo-Burmese border. 57th Mountain Division took part in the Indo-Pakistani War of 1971 as part of IV Corps. It also successfully conducted Operation Golden Bird in 1995 to eliminate rebels in Northeast India.
