The freedom struggle's final phase, Partition & integration
The final phase of India's freedom struggle (1942-1947): Quit India, Cabinet Mission, Mountbatten Plan, Partition and the integration of princely states.
From Quit India to the Crisis of 1945-46
The Quit India movement, launched on 8 August 1942 at the Bombay session of the AICC with Gandhi's call to 'Do or Die', marked the freedom struggle's most militant mass phase. The Congress Working Committee was arrested at dawn on 9 August 1942 under the Defence of India Rules; leaderless, the movement turned spontaneous and violent, with parallel governments established at Ballia (Chittu Pandey), Tamluk (Jatiya Sarkar, Midnapore) and Satara (Prati Sarkar under Nana Patil). The British crushed it by 1943 but conceded that India could no longer be governed by the old order.
Subhas Chandra Bose, having escaped to Germany in 1941, reached Singapore in July 1943, reorganised the Indian National Army and proclaimed the Provisional Government of Free India (Azad Hind) on 21 October 1943. The INA's 1945-46 trials at the Red Fort — the Shah Nawaz Khan, P.K. Sahgal and G.S. Dhillon case — became a rallying point; Bhulabhai Desai, Tej Bahadur Sapru and Nehru appeared for the defence.
The Wavell Era and the Cabinet Mission
The Simla Conference (June-July 1945), convened by Viceroy Wavell, collapsed over Jinnah's insistence that the Muslim League alone nominate Muslim members. The 1945-46 elections gave Congress overwhelming general-seat majorities and the League nearly all reserved Muslim seats, hardening the two-nation polarity. The RIN Mutiny of February 1946 at Bombay signalled that even the armed services were slipping.
The Cabinet Mission (Pethick-Lawrence, Stafford Cripps, A.V. Alexander) arrived in March 1946 and on 16 May 1946 rejected Pakistan, proposing instead a three-tier federation: autonomous provinces grouped into Sections A, B and C, with a weak Centre handling defence, foreign affairs and communications. Congress and the League both accepted, then quarrelled over the compulsory grouping clause. Jinnah withdrew acceptance and called Direct Action Day on 16 August 1946, triggering the Great Calcutta Killings (over 4,000 dead) and communal carnage across Noakhali, Bihar and the Punjab. The interim government under Nehru was sworn in on 2 September 1946; the League joined reluctantly on 26 October 1946 but worked to wreck it from within. By early 1947 the constitutional deadlock and spreading violence had made a united transfer of power impossible.
