Mitro Bahini order of battle

TheIndian Armyhad no standby force ready in 1971 with the specific task of attackingEast Pakistan,one of the many reasons whyIndiadid not immediately intervene afterPakistanlaunchedOperation Searchlightin March 1971. Indian Army'sEastern Commandwas tasked with defending the northern and eastern borders and fighting the insurgencies inNagaland,MizoramandNaxalitesinWest Bengalat that time.

Mukti Bahini,aided by the Indian army throughOperation Jackpot,led the struggle against thePakistan Armywhile the Indian Army readied for intervention. GeneralM. A. G. Osmani,Commander-in-ChiefBangladesh Forces,had divided Mukti Bahini forces into 11 geographical sectors for command and control purpose. Mukti Bahini forces numbered 30,000 regular soldiers (including 3 brigades containing 8 infantry battalions and 3 artillery batteries) and at least 100,000 guerrillas by December 1971.

The Indian Army Eastern Command assembled two existing infantry corps, theIV Corpsand theXXXIII Corps,for operations in Bangladesh, and created a new corps (II Corps)besides reorganising the 101 Communication Zone as a combat formation.On 21 November 1971, the Indian and Bangladesh forces were put under a joint command structureIndia Bangladesh force in the eastern theatre,led byLieutenant GeneralJagjit Singh Aurora,and this force came to be known asMitro Bahini.In addition to 29 battalions of theBorder Security Force(BSF),Mukti Bahini guerrillas operating near the border or awaiting deployment in camps inside India were organised into infantry companies and attached to various Indian formations.
