Partitions having become a fait accompli, Gandhis efforts from now on were directed to mitigating its risks. He paid brief visits to Kashmir, the Punjab and Bengal. In Calcutta, just before the transfer of power, his presence had a magical effect; the communal tensions and hatreds of the preceding twelve months vanished almost overnight. When there was a recrudescence of trouble a fortnight later, he went on a fast which electrified the town, moved the Muslims and shamed the Hindus. The leaders of all communities pledged themselves to peace and begged Gandhi to break the fast. The Calcutta fast was rightly acclaimed as a miracle; in the of-quoted words of the London Times, it did what several divisions of troops could not have done.
Gandhi now felt free to turn to Punjab which was witnessing one of the major migrations of population in history. Seized with fantastic hopes and fears, the villages and town of the Punjab had been dreading, and at the same time, preparing for a battle of the barricades. The administrative paralysis caused by the reshuffling of administrative cadres on a communal basis, and the infection of the police and military with communal virus had, by the end of August, led to a situation in which it was impossible for the Hindu minority to stay in West Punjab and the Muslim minority to stay in the East Punjab.

As the interminable caravans of refugees with their
tales of woes crawled to their destinations, violence spread. When Gandhi arrived in Delhi
early in September, he found it paralysed by communal tension. The Government, led by
Nehru, had acted energetically and impartially. Gandhi was not content with a peace
imposed by the police and the military; he wanted violence to be purged form the hearts of
Hindus and Muslims. It was an uphill task. Delhi had a number of refugee camps, some of
which housed Hindus and Sikhs from West Pakistan, while others sheltered Muslims fleeing
from Delhi for a passage across the border.
