The Presidency armies were abolished with effect from 1 April 1895 when the three Presidency armies became the Indian Army. The Indian Army was divided into four Commands each under a lieutenant general. In 1908, the four commands were merged into two Armies : this system persisted until 1920 when the arrangement reverted to four commands again. In 1914, the Southern Army consisted of the 4th Division, the 5th Division, the 6th Division, the 9th Division, and the Aden Brigade. During World War II, Southern Command was reformed as Southern Army in April 1942. The formation reverted to the title Southern Command in November 1945.
World War II
Component divisions included:
19th Indian Infantry Division, April 1942 to July 1944
2nd British Infantry Division, June 1942 to April 1943, and then June 1945 to August 1945
70th British Infantry Division, July 1943 to October 1943
In August 1947, Southern Command had the Deccan, Madras and Bombay Areas. In 1947–48, Southern Command was largely responsible in getting Junagadh and Hyderabad to sign the instrument of accession to India. 1st Armoured Division did the actual incursion into Hyderabad. In 1961, the Indian annexation of Goa was conducted by 17th Infantry Division and 50th Parachute Brigade, under the operational control of Southern Command. In 1965–66, two further divisions were raised within the command. After fighting broke out in the Rann of Kutch in April 1965, a hastily constituted force, named Kilo Force under Maj. Gen P. O. Dunn was formed to contain this attack. Kilo Force was later re-designated as 11 Infantry Division. In September 1965, the operational responsibility for the Barmer sector was given to Southern Command and entrusted to 11 Infantry Division. Delhi and Rajasthan Area, with its Advance Headquarters at Jodhpur, fought in the Indo-Pakistani War of 1965 under Western Command. On 3 November 1966, this formation was redesignated 12th Infantry Division, under Major General J.F.R. Jacob, and also placed under Southern Command. Today the command headquarters is located at Pune Cantonment in Pune, Maharashtra. It consists of two corps and two military areas. The two areas appear to be : one at Mumbai, the Maharashtra Goa and Gujarat Area, responsible for those states; and one at Chennai, the Andhra, Tamil Nadu, Karnataka and Kerala Area responsible for Andhra Pradesh, Tamil Nadu, Karnataka and Kerala. The Southern Command encompasses nine states and four union territories which covers about 40% of India. In 2005, some changes to the command's boundaries were made when a new South Western Command was established. Its components include:
XII Corps, headquartered at Jodhpur, Rajasthan
*4th Armoured Brigade
*340th Mechanized Brigade
*11th Infantry Division headquartered at Ahmedabad, Gujarat
