Although the Portuguese king had ceded all the islands of Bombay to the British king Charles II of England, the Portuguese in India refused to hand over the territory. It was not till 1675 that Aungier actually took possession of Colaba and Old Woman's Island, thus completing the transfer of power to the British. His plan of fortifying the main island, from Dongri in the north to the harbour, had to wait until 1715 for completion, when Charles Boone became the governor of the town.
