were combat-ready, and they would be competing for rail carriages with the grain harvest. He also pointed out the Himalayan passes would soon open up with the forthcoming monsoon, which would result in heavy flooding. After the cabinet had left the room, Manekshaw offered to resign; Gandhi declined and instead sought his advice. He said he could guarantee victory if she would allow him to handle the conflict on his own terms, and set a date for it; Gandhi agreed. Following the strategy planned by Manekshaw, the army launched several preparatory operations in East Pakistan, including training and equipping the Mukti Bahini, a local militia group of Bengali nationalists. About three brigades of regular Bangladeshi troops were trained, and 75,000 guerrillas were trained and equipped with arms and ammunition. These forces were used to harass the Pakistani Army stationed in East Pakistan in the lead-up to the war. The war started officially on 3 December 1971, when Pakistani aircraft bombed Indian Air Force bases in the western part of the country. The Army Headquarters, under Manekshaw's leadership, formulated the following strategy: II Corps, commanded by Lt. Gen. Tapishwar Narain Raina (later general and COAS), was to enter from the west; IV Corps, commanded by Lt. Gen. Sagat Singh, was to enter from the east; XXXIII Corps, commanded by Lt. Gen. Mohan L. Thapan, was to enter from the north; and the 101 Communication Zone Area, commanded by Maj. Gen. Gurbax Singh, was to provide support from the northeast. This strategy was to be executed by the Eastern Command, under Lt. Gen. Jagjit Singh Aurora. Manekshaw instructed Lt. Gen. J.F.R. Jacob, chief of staff Eastern Command, to inform the Indian prime minister that orders were being issued for the movement of troops from Eastern Command. The following day, the navy and the air force also initiated full-scale operations on both eastern and western fronts. As the war progressed, Pakistan's resistance crumbled. India captured most of the advantageous positions and isolated the Pakistani forces, which started to surrender or withdraw. The UN Security Council assembled on 4 December 1971 to discuss the situation. After lengthy discussions on 7 December, the United States put forward a resolution for "immediate cease-fire and withdrawal of troops" While supported by the majority, the USSR vetoed it twice and, because of Pakistani atrocities against Bengalis, the United Kingdom and France abstained. Manekshaw addressed the Pakistani troops by
