Even though the British and French vacated all their colonial possessions in the Indian subcontinent, Portugal refused to relinquish control of its colonies of Goa, Daman, and Diu. After repeated attempts by India to negotiate were spurned by Portuguese prime minister and dictator, António de Oliveira Salazar, on 12 December 1961 India launched Operation Vijay to capture the Portuguese colonies, which was accomplished by small contingents of Indian troops. After a brief conflict that lasted twenty-six hours—during which 31 Portuguese soldiers were killed, the Portuguese Navy frigate NRP Afonso de Albuquerque was destroyed, and over 3,000 Portuguese were captured—Portuguese General Manuel António Vassalo e Silva surrendered to Major General Kunhiraman Palat Kandoth of the Indian Army. Goa, Daman, and Diu became a part of the Republic of India.
