Initial construction began in 1853 under the supervision of 1st Lt. Zealous B. Tower, U.S. Corps of Engineers, and included four gun batteries, a 200' by 100' brick citadel, two barracks buildings, and three cell blocks. By 1858, the four batteries were virtually complete and armed. The South, North, West, and Three Gun batteries contained a total of 73 large guns including eight 10" Columbiads, forty-four 8" Columbiads, six 42 pounder smoothbore cannons and eight 24 pounder howitzers. The fort barracks was completed and the post was garrisoned on 30 Dec 1859 by Company H, 3rd U.S. Artillery, commanded by Capt. Joseph Stewart. U.S. Civil War (1861-1865) 2 - 8" Rodman Guns at Alcatraz The island was a key artillery post guarding San Francisco Bay against Confederate raiders and was the most heavily armed post in the San Francisco Harbor. By 1861, the fort had 86 cannon and a garrison of 130 men. Later in the war, the garrison and the armament were further increased. The Army also imprisoned deserters, insubordinate soldiers and Confederate sympathizers on the island during the war marking the beginning of the prison role for the island. Fortifications on the island expanded during the war and evolved into an almost continuous set of batteries along the north, west and south sides of the island. The practice of naming batteries for the compass points they faced proved too confusing, and later in the war batteries were named for military figures, including those who supervised the construction of the post. The north side of the island held Battery Halleck and Battery Rosecrans. The west side included Battery Mansfield, Battery Stevens, Battery Tower, Battery McPherson and part of Battery McClellan. The south side included part of Battery McClellan, Battery Prime, and the Three Gun Battery. Alcatraz 1867 Plan Post U.S. Civil War (1866-1876) Alcatraz 1866 Tunnel An inspection of Alcatraz fortifications in 1868 found a total of 155 large caliber weapons, 105 mounted and 50 unmounted. Construction was stopped in 1866 on casemates because of their vulnerability to the new rifled guns and the "very imperfect" defenses of the island. In 1870, a new plan was approved that called for thirty-five 15" Rodman cannons and 20 magazines organized into 13 batteries. In 1868, the Army established a permanent military prison on Alcatraz that housed a disciplinary barracks for military personnel and later a POW camp for Spanish-American War prisoners. After the 1906 San Francisco earthquake it was used to temporarily house civilian prisoners from the city jails. In 1907 it reverted back to being a military prison. On 21 Mar 1907, Alcatraz was officially designated as the Western U.S. Military Prison. In 1909, the Army demolished much of the original fort including most of the citadel and started building a new prison that included the huge concrete main cell block that was completed in 1912. World War I (1917-1918) During World War I the post was used to house conscientious objectors. In 1934 the Army turned the post over to the Federal Prison System.
