TheIII Corps is a formation of theIndian Army that was formed duringWorld War I inMesopotamia during itsrespective campaign. Prior to the reorganization of the British and Indian forces inMesopotamia, it was designated as theTigris Corps.

A new III Corps was formed by theIndian Army during World War II for service inSoutheast Asia. The corps fought in theBattle of Singapore where it surrendered in February 1942.^[1]

It is headquartered in the state ofNagaland of India in the city ofDimapur, at Rangapahar Military Station.

3 Corps was raised during World War I by Lt Gen Ahlmer and soon thereafter, the command was changed to Lt GenFrederick Stanley Maud, who was appointed as the Corps Commander on 09 Dec 1915. 3 Corps was allotted the6th (Poona) Division and12th Indian Division along with a Cavalry Brigade and tasked with the defence of the Tigris Line.  The Corps thereby earned the sobriquet of "The Tigris Corps". 3 Corps played a major role in the Mesopotamian front, which was a campaign in the middle eastern theatre of World War I, fought between the Allies represented by the British Empire, troops from Britain, Australia and vast majority of British Raj, against the central powers, mostly the Ottoman Empire. The Theatre was vast and consisted of hot, inhospitable desert terrain.  Tank warfare had still not achieved its primacy and deserts remained primarily a no man’s land. The fight was concentrated along the course of Tigris and the Euphrates rivers where Ottomans had a head start. The British had realised that they needed to secure and control the delta of Tigris at Shatt-El-Arab and Basra to deny the Ottomans access to Abadan Refinery and the oil rich delta. It also provided the British with a bridgehead for the induction of troops through the sea route and to maintain their forces logistically during future operations in the north. Keeping this as the broad objective, the British dispatched the 6th Indian Division as the Indian Expeditionary Force to Basra in 1915.

The Corps was later split into two separate formations, namely 1 and 3 Corps.  I Corps moved northwards towardsMosul, while 3 Corps led a renewed offensive towardsBaghdad, which finally fell to 3 Corps in 1916. The composition of 3 Corps was largely Indian troops and the credit for the swift capture of Baghdad was attributed to them. The Allied forces controlled a major part of Mesopotamia because of the fall ofBaghdad, and most importantly, had direct access to the sea and the oldest refinery of Asia at Abadan.  In view of the strategic objective of bringingMesopotamia under British control and liberation ofKuwait from Ottoman control being achieved, an armistice was signed between the British and the Ottoman Empire.

The military phase of the operations in theMiddle East was over, paving the way for political and diplomatic overtures.  3 Corps which had played a great role in achievement perhaps did not get its due compared to similar forces fighting in the European Theatre. The Corps was finally demobilized in 1919, only to be resurrected in 1941 during World War II.

HQ 3 Corps was raised on 27 Apr 1941 with headquarters atKuala Lumpur.  Lt Gen Percy Heath was placed in Command of the Corps.  It had two Divisions, namely the 9th and11th Indian Divisions under command.

11th Indian Division which was tasked to defendKuala Lumpur and withdraw towardsThailand was outflanked by the Japanese. The Division fought major battles atJitra from 08-12 Dec 1941, Kampar from 30 Dec 1941 to 02 Jan 1942,Slim River from 06 Jan to 08 Jan 1942, Gemas and Muar River from 14 Jan to 02 Jan 1942 and gave a good account of themselves, despite debilitating logistic shortcoming and virtually no air support.9th and11th Indian Division suffered significant casualties without any significant reinforcements.

During theMalayan campaign, 3 Corps had borne the brunt of War, and men suffered from inclement weather and tropical diseases apart from enemy action.  Jungle terrain coupled with intolerable tropical weather and humidity made the conditions insuperable. Fighting here required the very best of human endurance, both mental and physical.  3 Corps had fought most of its battles in these virtually inhuman conditions, but there was little coverage of the same. While the trenches of Ypres, Somme, Alsace and Lorraine and those who fought in them were widely covered, the contributions of the anonymous Indians who died in Malaya remain un-recounted. 3 Corps virtually ceased to exist post Feb 1942.

The Naga insurgency, over a period, gained inroads into the Hill districts of Manipur, Tirap and Changlang district of Arunachal Pradesh bordering Nagaland. 8 Mountain Division was re-raised in 1962 located at Zakhama.

Spear Corps participated in the 1962 Indo – China war. The famousBattle of Walong was in the then NEFA (Arunachal Pradesh). In autumn of 1962, during the Sino-Indian War, Walong was the scene of the Battle of Walong, where the Indian Army 11th Infantry Brigade battled the Chinese advances.[7] The killed and wounded numbered 642 Indians and 752 Chinese.[8] Indians were defeated at Walong, however the Chinese withdrawal allowed India to regain the territory.[6] A canopied memorial to the Indian war dead of 1962 was erected next to the airstrip with the following verses composed by a Walong veteran inscribed on it:[6]

The sentinel hills that round us stand

bear witness that we loved our land.

Amidst shattered rocks and flaming pine

we fought and died on Namti Plain

.

O Lohit gently by us glide

pale stars above us softly shine

as we sleep here in sun and rain.

Spear Corps was the formation directly under Headquarters Eastern Command to conduct operations against Naga insurgents. The spread of insurgency into new areas of Mizoram and Tripura necessitated the induction of additional troops.  With the raising of 57 Mountain Division in 1969 at Masimpur, 8 Mountain Division was entrusted with Counter Insurgency Operations in Nagaland and Manipur, while 57 Mountain Division was responsible for conduct of operations in Mizoram and Tripura.  Assam Rifles units were also involved in counter insurgency operations under respective brigade sized sector headquarters. There was a need to adopt a common cause and manifest a common effort.  It was this requirement which precipitated the thought process for establishing a new headquarters as an umbrella organisation to counter the eco system of insurgency and eradicate it in a comprehensive manner.  The seed for raising of a new Corps headquarter was sown in response and the idea of 3 Corps sprouted.

In 1984, Lt Gen Chiman Singh, the then General Officer Commanding-in Chief, Eastern Command deliberated upon the command, control and coordination of operations of the two Divisions fighting insurgency in the North East and decided to coordinate and streamline functioning of both these Formations under a Corps Headquarter. Headquarters 3 Corps was raised on 04 Feb 1985, by Lt Gen Joginder Singh Bakshi, MVC, at Rangapahar Military Station (RMS) in Dimapur (Nagaland) for coordination and conduct of Counter Insurgency Operations in Nagaland, Manipur, Mizoram, Tripura, Meghalaya, South Assam (including Dhubri Districts) and Arunachal Pradesh (Tirap and Changlang districts). 3 Corps replaced 8 Mountain Division as the highest Formation responsible for coordinating Counter Insurgency Operations in Nagaland and the adjoining Naga inhabited areas of other states.

The formation sign is inspired by the primary role of Infantry. Fittingly, the formation signs of the two formations under Head Quarters 3 Corps, the Bayonet of                         8 Mountain Division and Crossed Spears of 57 Mountain Division, were superimposed to make the 3 Corps formation sign.

At the time of its formation, 3 Corps consisted of 8 Mountain Division and 57 Mountain Division, under its command. Additionally, Headquarters Inspector General Assam Rifles (North) (IGAR(N) was raised at Jorhat on 15 May 1985 and placed under operational control of 3 Corps. Post raising, the Headquarters IGAR(N) moved to Imphal and took over the operational responsibility of Manipur from 8 Mountain Division on 12 Nov 1986.  8 Mountain Division took over the responsibility of Tirap Sector.

3 Corps was actively involved in counter-insurgency operations in Manipur, Tripura and North Cachar Hills district of Assam. Besides, 3 Corps was also aiding the civil administration and paramilitary forces in maintaining peace in Nagaland and Mizoram. At the time, 3 Corps seemed likely to be replaced by the Directorate-General of Assam Rifles based inShillong.  The 57 Mountain Division based atLeimakhong inManipur had already been shifted to Meerut in Uttar Pradesh.

Defending the LAC became an additional responsibility, apart from countering insurgency. With this additional responsibility to fulfil, two more Divisions were placed under command of HQ 3 Corps.  With the raising of the Division Headquarters, its formations and units commenced its operations on 7 September 2009 under Major General Raj Nandan Singh. It took over the operations and entire responsibility of WesternArunachal Pradesh on 01 Jun 2010.
