Fort Wool
Fort Wool is a decommissioned island fortification located in the mouth of Hampton Roads, adjacent to the Hampton Roads Bridge-Tunnel (HRBT). Now officially known as Rip Raps Island, the fort has an elevation of 7 feet and sits near Old Point Comfort, Old Point Comfort Light, Willoughby Beach and Willoughby Spit, approximately one mile south of Fort Monroe. Originally named Castle Calhoun or Fort Calhoun after Secretary of War John C. Calhoun, the fort was renamed after Maj. Gen. John Ellis Wool on 18 March 1862 during the American Civil War. It is noted on current nautical maps as "Rip Raps", and was sometimes referred to by that name during the Civil War. Fort Wool was one of more than forty forts started after the War of 1812, when British forces sailed the Chesapeake Bay to burn the Capital. This program was later known as the third system of U.S. fortifications. Designed by Brigadier General of Engineers Simon Bernard, an expatriate Frenchman who had served as a gener ...

Harbor Defense Command
A Harbor Defense Command was a military organization of the United States Army Coast Artillery Corps designated in 1925 from predecessor organizations dating from circa 1895. It consisted of the forts, controlled underwater minefields, and other coastal defenses of a particular harbor or river. Harbor Defense Commands, along with the similar Coast Artillery Corps, were disestablished in 1950. History These commands originated as Artillery Districts, to control groups of forts constructed under the Endicott Program beginning in 1895. A 1909 reference shows that districts could include (depending on size) a Battle Command (later Fort Command), Fire Command, Mine Command, and Battery Commands. Mine planter vessels were also attached to these commands to plant and maintain controlled minefields. In 1913 the districts were redesignated as Coast Defense Commands, called "Coast Defenses of..." the area protected.Rinaldi, pp. 165-166 At this time Coast Artillery Districts became regional ...

Fort Monroe
Fort Monroe, managed by partnership between the Fort Monroe Authority for the Commonwealth of Virginia, the National Park Service as the Fort Monroe National Monument, and the City of Hampton, is a former military installation in Hampton, Virginia, at Old Point Comfort, the southern tip of the Virginia Peninsula, United States. Along with Fort Wool, Fort Monroe originally guarded the navigation channel between the Chesapeake Bay and Hampton Roads—the natural roadstead at the confluence of the Elizabeth, the Nansemond and the James rivers. Union General George B. McClellan landed his forces at the fort during Peninsula campaign of 1862 during the American Civil War. Until disarmament in 1946, the areas protected by the fort were the entire Chesapeake Bay and Potomac River regions, including the water approaches to the cities of Washington, D.C. and Baltimore, Maryland, along with important shipyards and naval bases in the Hampton Roads area. Surrounded by a moat, the six-side ...

Barbette
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. Sh ...

Casemate
A casemate is a fortified gun emplacement or armored structure from which artillery, guns are fired, in a fortification, warship, or armoured fighting vehicle.Webster's New Collegiate Dictionary When referring to Ancient history, antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see #Antiquity: casemate wall, Antiquity: casemate wall). In its original early modern meaning, the term referred to a vaulted chamber in a fort, which may have been used for storage, accommodation, or artillery which could fire through an opening or embrasure. Although the outward faces of brick or masonry casemates proved vulnerable to advances in artillery performance, the invention of reinforced concrete allowed newer designs to be produced well into the 20th century. With the introduction of ironclad warships, the definition was widened to include a prot ...

Sailing Ballast
Ballast is used in ships to provide moment to resist the lateral forces on the hull. Insufficiently ballasted boats tend to tip or heel excessively in high winds. Too much heel may result in the vessel capsizing. If a sailing vessel needs to voyage without cargo, then ballast of little or no value will be loaded to keep the vessel upright. Some or all of this ballast will then be discarded when cargo is loaded. Uses Ballast takes many forms. The simplest form of ballast used in small day sailers is so-called "live ballast", or the weight of the crew. By sitting on the windward side of the hull, the heeling moment must lift the weight of the crew. On more advanced racing boats, a wire harness called a trapeze is used to allow the crew to hang completely over the side of the hull without falling out; this provides much larger amounts of righting moment due to the larger leverage of the crew's weight, but can be dangerous if the wind suddenly dies, as the sudden loss of heeling ...

Shoal
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refer ...

Seacoast Defense In The United States
Seacoast defense was a major concern for the United States from its independence until World War II. Before Military aviation, airplanes, many of America's enemies could only reach it from the sea, making coastal forts an economical alternative to Standing army, standing armies or a large navy. After the 1940s, it was recognized that fixed fortifications were obsolete and ineffective against aircraft and missiles. However, in prior eras foreign fleets were a realistic threat, and substantial fortifications were built at key locations, especially protecting major harbors. The defenses heavily depended on fortifications but also included Submarine mines in United States harbor defense, submarine minefields, nets and boom (navigational barrier), booms, ships, and airplanes. Therefore, all of the armed forces participated in seacoast defense, but the United States Army Corps of Engineers, U.S. Army Corps of Engineers played the central role in constructing fixed defenses. Designs evo ...

Burning Of Washington
The Burning of Washington was a British invasion of Washington City (now Washington, D.C.), the capital of the United States, during the Chesapeake Campaign of the War of 1812. It is the only time since the American Revolutionary War that a foreign power has captured and occupied the capital of the United States. Following the defeat of American forces at the Battle of Bladensburg on August 24, 1814, a British force led by Major General Robert Ross marched to Washington. That night, British forces set fire to multiple government and military buildings, including the White House (then called the ''Presidential Mansion''), the Capitol building, as well as other facilities of the U.S. government. The attack was in part a retaliation for American destruction in Upper Canada: U.S. forces had burned and looted its capital the previous year and then had burned buildings in Port Dover. Less than four days after the attack began, a heavy thunderstorm—possibly a hurricane— ...

War Of 1812
The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States of America and its indigenous allies against the United Kingdom and its allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on 18 June 1812 and, although peace terms were agreed upon in the December 1814 Treaty of Ghent, did not officially end until the peace treaty was ratified by Congress on 17 February 1815. Tensions originated in long-standing differences over territorial expansion in North America and British support for Native American tribes who opposed US colonial settlement in the Northwest Territory. These escalated in 1807 after the Royal Navy began enforcing tighter restrictions on American trade with France and press-ganged men they claimed as British subjects, even those with American citizenship certificates. Opinion in the US was split on how to respond, and although majorities in both the House and ...

Riprap
Riprap (in North American English), also known as rip rap, rip-rap, shot rock, rock armour (in British English) or rubble, is human-placed rock or other material used to protect shoreline structures against scour and water, wave, or ice erosion. Ripraps are used to armor shorelines, streambeds, bridge abutments, foundational infrastructure supports and other shoreline structures against erosion. Common rock types used include granite and modular concrete blocks. Rubble from building and paving demolition is sometimes used, as well as specifically designed structures called tetrapods. Riprap is also used underwater to cap immersed tubes sunken on the seabed to be joined into an undersea tunnel. Environmental effects Sediment effects Ripraps cause morphological changes in the riverbeds they surround. One such change is the reduction of sediment settlement in the river channel, which can lead to scouring of the river bed as well as coarser sediment particles. This can be combat ...
