The U.S. Government initially purchased enough land on Great Brewster Island to build a seawall in 1848. The remainder of the island, 21.7 acres in total, was purchased on 18 Aug 1917 during World War I as a searchlight station. The reservation was abandoned after the end of the war.

In 1920, there was some thought given to installing a naval battleship gun turret with two 16" guns on Great Brewster Island Military Reservation but the plan was never implemented. During the 1920s and 1930s a number of civilian cottages were built on the island without the permission of the U.S. Government, some 24 occupants were noted in 1930. Some cottages can already be seen on the 1919 plan. No harm was being done by these occupants and the government derived some benefit from their presence so the government granted revokable licenses at 5 dollars per year to the occupants. The licenses were probably revoked at the outset of World War II.
