When Jinnah was trying hard for the recognition and mass acceptance of Muslim League as the sole party for Muslims, primarily to make his dream of creating Pakistan into a reality, the responsibility to handle the Bengal Provincial Muslim League (BPML) had passed on the hands of Huseyn Shaheed Suhrawardy, the last Premier of the undivided province of Bengal. Almost all the riots of the 1940s were explosive by nature. Yet, the ‘Great Calcutta Killing’ of 1946 overshadowed all previous techniques, modes, reasons, politics, participations and manifestations of riots in Bengal. It culminated through stages of fusion between nationalist and class-consciousness. The Muslim League, however, decided to ‘bid good-bye to the constitutional methods’ and had taken a programme of ‘direct action for the achievement of Pakistan’ for accomplishing a separate land for the Muslims. The direct action was supposed to result from ‘British betrayal’, it was planned against ‘the contemplated future of caste-Hindu domination’ in Congress. Jinnah said in the press conference, ‘I am not going to discuss ethics’. Nazimuddin misguided the League followers by saying that Jinnah asked for action against the Hindus. The whole of India was aware of the declaration by the Muslim League. As reported previously by other political parties, Suhrawardy and his administration would be in favor of the Muslims on 16th August. It became a ‘jehad against everyone who did not accept Pakistan’. The absolute decline of the law and order, reports of looting, stabbing, rioting by the social agents, mutual hatred, lack of confidence of other communities, created panic in Calcutta and all over Bengal. The vernacular press deliberately published provocative pictures of their brethren. It aggravated tension, instigated both communities to organize revenge in padas (neighborhood). The headline of the Morning News was ‘Recrudescence of Disturbances in Calcutta: Twenty Four killed and 51 Injured: Panic and Tension in the city’, whereas the official version was in the very first day at least 5,000-6,000 people murdered in Calcutta. The genocide continued for 4 days more, when a huge percentage of total population of Calcutta either fled or migrated, from both communities. Contemporary memoirs depicted shocking evidence that made Calcutta ‘a horror city’ and the transformation was ’like a nightmare’.
