,
Brooklyn, NY. , Washington state. In 1885,
William C. Endicott,
President Grover Cleveland's
Secretary of War, was tasked with creating the
Board of Fortifications to review seacoast defenses. The findings of the board illustrated a grim picture of existing defenses in its 1886 report and recommended a $127 million construction program of breech-loading cannons,
mortars, floating batteries, and
submarine mines for some 29 locations on the US coastline. Most of the Board's recommendations were implemented. Coast Artillery fortifications built between 1885 and 1905 are often referred to as Endicott Period fortifications. The
Watervliet Arsenal designed the gun and built the barrels. A few of the first guns were mounted on low-angle M1893
barbette carriages. Subsequently, most of the guns were mounted on M1894, M1896, or M1901
disappearing carriages; when the gun was fired, it dropped behind a concrete and/or earthen wall for protection from
counter-battery fire. Detailed descriptions of the M1888 weapon and Buffington–Crozier disappearing carriage are in the US Army's Artillery circular 1895, pp. 183–195, along with a description and illustration of a "modified Gordon" disappearing carriage, an experimental type. Detailed parts lists for the M1888M1 weapon and supporting equipment are in the Ordnance supply manual by George L. Lohrer, United States Army, Ordnance Dept, 1904, pp. 47–113. After the
Spanish–American War, the government wanted to protect American seaports in the event of war, and to protect newly gained territory, such as the
Philippines and
Cuba, from enemy attack. A new Board of Fortifications, under President
Theodore Roosevelt's Secretary of War
William Taft, was convened in 1905. Taft recommended technical changes, such as more searchlights, electrification, and in some cases fewer guns in particular fortifications. The seacoast forts were funded under the Spooner Act of 1902 and construction began within a few years and lasted into the 1920s. The defenses of the Philippines on islands in
Manila Bay and Subic Bay were built under this program.
Experimental gun A 10-inch "depressing gun"
M1896 on an M1894 disappearing carriage was mounted in an experimental battery at
Fort Monroe, Virginia in the northeast bastion. The battery was operated from 1900 to 1908, and the concrete portions remain in place.
Railway mounting After the
American entry into World War I, the Army recognized the need for large-caliber
railway guns for use on the Western Front. Among the weapons available for this were 129 10-inch guns, to be removed from fixed defenses or taken from spares. Thirty-six
Schneider-type sliding-mount railway carriages for 10-inch guns were contracted to be manufactured by the
Marion Steam Shovel company and delivered to France for finishing by March 1919. Of these, eight sets were shipped prior to the
Armistice, then were returned to the US where 22 of the 36 originally contracted mountings were completed. A detailed description of the railway mounting is given in
Railway Artillery, Vol. I by Lt. Col. H. W. Miller, USA. The range of the railway weapon was at 36° elevation. Guns not mounted were returned to coastal defenses after the war; in the late 1920s the 10-inch railway gun was declared obsolete and the mountings scrapped.
World War II In April–May 1941 eight M1888 guns were sent to Canada under
Lend-Lease for use in coast defenses there. These included three guns from Battery Harker,
Fort Mott on disappearing carriages, three guns from Battery Quarles,
Fort Worden on barbette carriages, and two guns from Battery Revere,
Fort Flagler on barbette carriages. Two of the Fort Mott disappearing guns were deployed at Fort
Cape Spear,
St. John's, Newfoundland and remain there. The remaining disappearing gun from Fort Mott and one barbette gun from Fort Flagler were deployed at
Fort Prével on the
Gaspé Peninsula in
Quebec. Two of the barbette guns from Fort Worden were deployed to Fort McNutt on
McNutts Island, Nova Scotia and remain there, although only part of one still exists. The remaining two barbette guns from Forts Flagler and Worden were deployed at Wiseman's Cove,
Botwood, Newfoundland and no longer exist. Along with other coast artillery weapons, some of the 10-inch guns in the Philippines saw action in the
Japanese invasion in World War II. Since they were positioned against a naval attack, they were poorly sited to engage the Japanese, and the open mountings were vulnerable to air and high-angle artillery attack. In 1940–44,
16-inch gun batteries were constructed at most
harbor defenses, and essentially all 10-inch guns not in the Philippines were scrapped 1943–44. ==Surviving examples==
