[Q]: Information:  - Morris Island is an 840-acre (3.4 km²) uninhabited island in Charleston Harbor in South Carolina, accessible only by boat. The island lies in the outer reaches of the harbor and was thus a strategic location in the American Civil War. The island forms parts of the cities of Charleston and Folly Beach, in Charleston County.  - A blockade runner is usually a lighter-weight ship used for evading a naval blockade of a port or strait, as opposed to confronting the blockaders to break the blockade. Very often blockade running is done in order to transport cargo, for example to bring food or arms to a blockaded city. In other cases the blockade runners would carry mail in an attempt to communicate with the outside world.  - A blockship is a ship deliberately sunk to prevent a river, channel, or canal from being used. It may either be sunk by a navy defending the waterway to prevent the ingress of attacking enemy forces, as in the case of HMS "Hood" at Portland Harbour; or it may be brought by enemy raiders and used to prevent the waterway from being used by the defending forces, as in the case of the three old cruisers HMS "Thetis", "Iphigenia" and "Intrepid" scuttled during the Zeebrugge raid in 1918 to prevent the port from being used by the German navy.  - The American Civil War was a civil war in the United States fought from 1861 to 1865. The Union faced secessionists in eleven Southern states grouped together as the Confederate States of America. The Union won the war, which remains the bloodiest in U.S. history.  - Tybee Island is a barrier island in Chatham County, Georgia, near Savannah in the southeastern United States. The name Tybee Island is also used for the city located on part of this island.  - The Charleston Harbor is an inlet (8 sq mi/20.7 km²) of the Atlantic Ocean at Charleston, South Carolina. The inlet is formed by the junction of Ashley and Cooper rivers at . Morris and Sullivan's Islands shelter the entrance. Charleston Harbor is part of the Intracoastal Waterway.  - USS Timor was purchased at Sag Harbor , New York on 30 October 1861 . She was sunk as part of the Stone Fleet at Maffitts channel in Charleston harbor on 25 or 26 January 1862 .  - The Union Navy was the United States Navy (USN) during the American Civil War, when it fought the Confederate States Navy (CSN). The term is sometimes used carelessly to include vessels of war used on the rivers of the interior while they were actually under the control of the United States Army, referred to in the same fashion as the Union Army.  - The Stone Fleet consisted of a fleet of aging ships (mostly whaleships) purchased in New Bedford and other New England ports, loaded with stone, and sailed south during the American Civil War by the Union Navy for use as blockships. They were to be deliberately sunk at the entrance of Charleston Harbor, South Carolina in the hope of obstructing blockade runners, then supplying Confederate interests. Although some sank along the way and others were sunk near Tybee Island, Georgia, to serve as breakwaters, wharves for the landing of Union troops, the majority were divided into two lesser fleets. One fleet was sunk to block the south channel off Morris Island, and the other to block the north channel near Rattlesnake Shoals off the present day Isle of Palms in what proved to be failed efforts to block access the main shipping channels into Charleston Harbor.
