Battery Carpenter (1906-1947) - Battery Carpenter was a reinforced concrete, Endicott Period 6 inch coastal gun battery on Fort McKinley, Great Diamond Island, Cumberland County, Maine. The battery was named in G.O. 78, 25 May 1903, after Major Stephen D. Carpenter (Cullum 1051), 19th U.S. Infantry, who was killed 31 Dec 1862, at the battle of Stone River, Tennessee, during the U.S. Civil War. Battery construction started in 1901, was completed in 1905 and transferred to the Coast Artillery for use 25 May 1906 at a cost of $ 45,400.00. Deactivated in 1947.
Endicott Period (1890-1910)
Part of the Harbor Defense of Portland, Maine.
Originally built as an Endicott Period concrete coastal gun battery with two 6" M1900 guns mounted on M1900 Pedestal carriages. This was a two story battery with the guns located on the upper level and the magazines below. Shells were moved from the magazine level to the gun loading platform by two Hodges back delivery shell hoists. No powder hoists were provided. Electrical power was furnished by the emplacement power plant in Battery Weymouth and the central power plant.
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. Both of the guns of Battery Carpenter were ordered dismounted for use abroad on 24 Aug 1917. Both guns were transferred on 28 Nov 1917 to Morgan for modification and eventual shipment to France. Both guns were transferred back from France to Battery Carpenter and remounted. Gun # 10 was transferred back on 27 May 1919 and gun # 9 was transferred back on 5 Dec 1919.
World War II (1941-1945)
Battery Carpenter was a part of the Harbor Defenses of Portland plan throughout World War II. After the war ended in 1945, the battery was declared surplus. The guns and carriages were processed for salvage about 1947.
Mostly private property on Great Diamond Island, Cumberland County, Maine. No period guns or mounts in place.
