Endicott Period (1890-1910)
Part of the Harbor Defense of Portland, Maine.
Fort McKinley was built on 111 acres of Great Diamond Island, Cumberland County, Maine. This land was purchased by the government in 1873 and 1901. The reservation was divided by Diamond Cove into the North Fork and the South Fork of the reservation. The North Fork housed five gun batteries and the main cantonment. The South Fork housed four gun batteries and the underwater mine facilities.
Construction began on the nine Endicott Period gun batteries in 1897 and by 1905 they were all complete, the last one formally accepted for service in 1906. The armament ranged from 12" mortars and rifles designed to take on capital ships of the day to rapid fire 3" guns designed to protect the mine fields from small minesweepers and torpedo boats.
The post cantonment was originally built out as a four company medium sized coast defense fort. The initial construction phase began in 1902-1903 and lasted through 1906. Four 109 man barracks were constructed along with four sets of duplex NCO quarters, six sets of duplex officer quarters, three sets of single family officer quarters and all the support buildings to support a post of this size. The housing was nearly all complete by the end of 1904 and most of the support building were also complete.
A few buildings were built during the period between 1905 and 1908 but a significant expansion began in 1908-1909. The expansion included two additional barracks, one of which was a double barracks, four more sets of duplex NCO quarters and a ten man bachelor officer quarters (BOQ). The expansion grew the post to a large seven company post with capacity for 17 officers, 18 married NCOs and 788 enlisted men. By the end of 1910 the majority of the expansion was complete. Two existing buildings, the hospital and the guardhouse, were expanded in 1910 to accomodate the increased population.
