Originally built as an Endicott Period concrete coastal gun battery with three 12" M1895 guns mounted on M1897 Disappearing carriages. This was a two story battery with the guns located on the upper level and the magazines below. Shells were originally moved from the magazine level to the gun loading platform by Hodges back delivery shell hoists. The Hodges hoists were replaced in 1919 with Taylor-Raymond shell hoists modified for the new long point shells. No separate powder hoists were provided. The carriages were provided with electric retracting motors. Electrical power was furnished by the central power plant.

World War I (1917-1918)

Battery Bowdoin Plotting Room

The U.S. entry into World War I resulted in a widespread removal of large caliber coastal defense gun tubes for service in Europe. Many of the gun and mortar tubes removed were sent to arsenals for modification and mounting on mobile carriages, both wheeled and railroad. Most of the removed gun tubes never made it to Europe and were either remounted or remained at the arsenals until needed elsewhere. The guns of Battery Bowdoin were not affected by the World War I redistribution or the following 1920 disarmament program.

World War II (1941-1945)
