DIGLIPUR

The British first settled the convicts and officials on the coast of Aerial Bay in the 18thCentury (1789) as per the recommendations of Lt. Archibald Blair. The settlement was named after the then Governor General Lord Cornwallis. The settlement had to be abandoned subsequently in 1793 due to the unprecedented attack of Malaria which left majority of the settlers dead. After about 170 years a settlement of refugees from East Bengal was established at a place nearby and given the name of Diglipur.(source:Directore General of Light Houses and Light Ships)

Wikipedia...In 1789 the government of Bengal established a penal colony on Chatham Island in the southeast bay of Great Andaman, now known as Port Blair (after the officer who founded it). After two years, the colony moved to the northeast part of Great Andaman and was named Port Cornwallis after Admiral William Cornwallis. However, there was much disease and death in the penal colony, and the government ceased operating it in May 1796.
