The 10-inch Gun M1895 (254 mm) and its variants the M1888 and M1900 were large coastal artillery pieces installed to defend major American seaports between 1895 and 1945. For most of their history they were operated by the United States Army Coast Artillery Corps. Most were installed on disappearing carriages, with early installations on barbette mountings.^[5] All of the weapons not in the Philippines (except four guns in Canada) were scrapped during World War II. Two of the surviving weapons were relocated from the Philippines to Fort Casey in Washington state in the 1960s.

History

Practice loading of a 10-inch gun at Fort Hamilton, Brooklyn, NY.

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 massive $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.

After the Spanish–American War, the government wanted to protect American seaports in the event of war, and also 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 less 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.^[6]

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 railway carriages for 10-inch guns were contracted to be delivered to France for finishing by March 1919; eight sets were shipped prior to the Armistice, then were returned to the US where 22 of the 36 originally contracted mountings were completed.^[7]^[8] A detailed description of the railway mounting is given in "Railway Artillery, Vol. I" by Lt. Col. H. W. Miller, USA.^[9] Probably all guns were returned to coastal defenses and all mountings scrapped after the war.

World War II

In 1941 seven 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,^[10] two guns from Battery Quarles, Fort Worden on barbette carriages,^[11] and two guns from Battery Revere, Fort Flagler on barbette carriages.^[12] Two of the Fort Mott 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 Prevel on the Gaspé Peninsula in Quebec. The two 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. It is unclear where or if the seventh gun was deployed.

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

Eight 10-inch guns remain at four locations.^[13]

1. Two 10-inch Guns M1895MI (#25 & #22 Watervliet) on Disappearing Carriages M1901 (#14 & #16 Watertown), Battery Grubbs, Fort Mills, Corregidor Island, Philippines. The guns lie behind their mountings, since they were fired while disconnected from the carriages to deny use of them to the Japanese forces.

2. One 10-inch Gun M1895MI (#20 Watervliet) (spare gun), Battery Grubbs, Fort Mills, Corregidor Island, Philippines

3. Two 10-inch Guns M1895MI (#26 & #28 Watervliet) on Disappearing Carriages M1901 (#13 & #15 Watertown), Battery Worth, Fort Casey, Coupeville, WA (guns moved in the 1960s from Battery Warwick, Fort Wint, Grande Island, Subic Bay, Philippines)

4. Two 10-inch Guns M1888 (#41 & #3 Watervliet), Fort Cape Spear, St. John's, Newfoundland and Labrador, Canada (guns moved in World War II from Battery Harker, Fort Mott, New Jersey)

5. One 10-inch Gun M1888 (#12 Watervliet) on Barbette Carriage M1893 (#11 Watertown) (with partial remains of other gun (#37) and carriage (#1), Fort McNutt, McNutts Island, Nova Scotia, Canada (guns moved in World War II from Battery Quarles, Fort Worden, WA)
