at the fort from 1831 to 1834 and played a major role in its final construction and its opposite, Fort Calhoun (renamed Fort Wool in 1862). He resided at Quarters 17. Fort Calhoun was built on a man-made island called the Rip Raps across the navigation channel from Old Point Comfort in the middle of the mouth of Hampton Roads. The Army briefly detained the Native American chieftain Black Hawk at Fort Monroe, following the 1832 Black Hawk War. When construction was completed in 1834, Fort Monroe was referred to as the "Gibraltar of Chesapeake Bay." The fort mounted an impressive complement of powerful artillery: 42-pounder cannon with a range of over one mile. In conjunction with Fort Calhoun (later Fort Wool), this was just enough range to cover the main shipping channel into the area. (Decommissioned after World War II, the former Fort Wool on Rip Raps is now adjacent to the southern man-made island of the Hampton Roads Bridge-Tunnel, first completed in 1957.) From 1824 to 1946 Fort Monroe was the site of a series of schools of artillery. The first was the Artillery School of Practice. The school was closed in 1834 but was revived during the period 1858–61. It was succeeded by the Artillery School of the U.S. Army, which existed from 1867 until its redesignation in 1907 as the Coast Artillery School. Fort Monroe also hosted the Old Point Comfort Proving Ground for testing artillery and ammunition from the 1830s to 1861; after the Civil War this function relocated to the Sandy Hook Proving Ground in New Jersey. American Civil War 1860–61 Fort Monroe played an important role in the American Civil War. On December 20, 1860, South Carolina became the first state to secede from the Union. Four months later, on April 12, 1861, troops of that state opened fire on Fort Sumter in Charleston Harbor. Five days later, Virginia's legislature passed (subject to voters' ratification) the Ordinance of Secession of Virginia to withdraw from the Union and join the newly formed Confederate States of America. On 23 May 1861, voters of Virginia ratified the state's secession from the union. President Abraham Lincoln had Fort Monroe quickly reinforced so that it would not fall to Confederate forces. It was held by Union forces throughout the Civil War, which launched several sea and land expeditions from there. A few weeks after the Battle of Fort
