The scale is what made the mutiny impossible to ignore. It began on a single ship and, within about seventy-two hours, involved roughly twenty thousand ratings, nearly seventy-eight ships, and around twenty shore establishments spread across every major Indian port โ Bombay, Karachi, Calcutta, Madras, Visakhapatnam and Cochin. At Karachi, the sloop HMIS Hindustan fought an actual gun battle with British forces before surrendering. In Bombay, the epicentre, the naval strike triggered a general sympathy strike: mills closed, crowds filled the streets, and clashes with British troops and police over 20โ22 February left several hundred civilians dead and well over a thousand injured, by the commonly cited figures. The ratings' demands went far beyond the galley โ equal pay and treatment with British sailors, faster demobilisation, release of the INA prisoners, and independence for India. The revolt lasted five days, from 18 to 23 February 1946, before the strike committee accepted surrender on the assurance of no reprisals. That assurance was largely broken: hundreds of ratings were dismissed or never re-enlisted, and for decades neither independent India nor Pakistan formally recognised them as freedom fighters, a neglect only partly corrected long afterwards.
