Endicott Period (1890-1910)
Part of the Harbor Defense of Portland, Maine.
Originally built as an Endicott Period concrete coastal gun battery with one 3" M1902MI gun mounted on a M1902 Pedestal carriage. This was a two story battery with the gun located on the upper level and the magazine below. Shells were moved from the magazine level to the gun loading platform by hand. No shell or powder hoists were provided. Electrical power was furnished by commercial power.
World War I (1917-1918)
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 Mason were not affected by the World War I redistribution or the following 1920 disarmament program.
World War II (1941-1945)
Battery Mason was a part of the Harbor Defenses of Portland plan throughout World War II. When the war ended in 1945 the battery was declared surplus. The guns and carriages were processed for salvage.
No period guns or mounts in place.
