The Burmese attacked Phuket in 1785. Francis Light, a British East India Company captain passing by the island, notified the local administration that he had observed Burmese forces preparing to attack. Than Phu Ying Chan, the wife of the recently deceased governor, and her sister Mook (คุณมุก) assembled what local forces they could. After a month-long siege of the capital city, the Burmese were forced to retreat on 13 March 1785. The women became local heroines, receiving the royal titles Thao Thep Kasattri and Thao Si Sunthon from a grateful King Rama I. During the reign of King Chulalongkorn (Rama V), Phuket became the administrative center of the tin-producing southern provinces. In 1933 Monthon Phuket (มณฑลภูเก็ต) was dissolved and Phuket became a province.
