2nd Infantry Division (India)

The 2nd Division was an infantry division of the Indian Army during World War II and was disbanded in 1944. In its present form, 2 Mountain Division, raised in 1962, is part of the Indian Army.

World War II
The 2nd Division was created for deception purposes in order to control Line of Communications and Sub-area formations within Persia and Iraq Command. It was formed by the re designation of the 30th Indian Infantry Brigade on 15 August 1942. It was later converted to HQ Northern Iraq Area on 15 October 1944.

During the period 1942–44 the division was converted and re-converted from the 31st Indian Infantry Brigade and the 90th Indian Infantry Brigade. 31 Indian Infantry Brigade was formed on 15 January 1943, from the Mosul-Teheran Lines of Communications Sub-Area. It only had two units assigned which were The Central India Horse (21st King George V's Own Horse) and the 2nd Hyderabad Infantry, Indian State Forces. On 15 May 1943 it was reconverted into 2 Indian Division. On 1 June 1943, 31 Indian Infantry Brigade was reformed from HQ Kermanshah LOC Sub-Area. The brigade was disbanded on 14 October 1944.

Thus 2 Indian Division had been reformed on 15 May 1943. Three months later, on 13 August 1943, it was reorganised as 90 Indian Brigade under Lieutenant-Colonel GH Pulling. 90 Indian Brigade served for ten months and then was disbanded in June 1944. Two days later, on 15 August 1943, 2 Indian Division was reformed again by the conversion of 30th Indian Infantry Brigade. This time, the division lasted fourteen months before being finally disbanded in October 1944 by conversion into Headquarters Northern Iraq Area.

One of the division's subordinate LOC areas/brigades was the 40th Indian Infantry Brigade. It was initially raised as Shaiba LOC Sub-Area in September 1942. What higher headquarters it was under at the time is not confirmable from present internet-accessible sources. However, the brigade then came under 2 Indian Division on 1 January 1943. In October 1944, when 2 Indian Division disbanded, the brigade was re-designated again as an lines of communication headquarters, this time as HQ South Iraq Area.

Post Independence
2 Infantry Division was re-raised in the Digboi-Tinsukia area in October 1962 during the Sino-Indian War, following the fall of Tawang. It was placed under IV Corps and was to be responsible for the whole of North-East Frontier Agency, except for Kameng Frontier Division. Major General Mohinder Singh Pathania was its first commander.

Sino-Indian War
Major General MS Pathania arrived at Walong on 26 October 1962 and took command of the newly raised division. 181 Brigade was placed under the division. But, General Pathania preferred to have Brigadier N. C. Rawlley and his 11 Brigade under his command. 11 Brigade was thus moved under 2 Division from Manipur to Lohit Frontier Division and 181 Brigade was moved to the India–Burma border. As of 31 October 1962, the order of battle (ORBAT) for 11 Infantry Brigade was  -
 * 4 Sikh

The ORBAT of 5 Infantry Brigade as on 18 November 1962 was-

On 27 October 1962, the Chinese ordered the launch of operations towards Limeking (Subansiri Frontier Division), Mechuka and Tuting (both in Siang Frontier Division).
