Harbor Defenses Of The Delaware
The Harbor Defenses of the Delaware was a United States Army Coast Artillery Corps Harbor Defense Command, harbor defense command. It coordinated the coastal defence and fortification, coast defenses of the Delaware River estuary from 1897 to 1950, beginning with the Board of Fortifications, Endicott program. These included both coastal artillery, coast artillery forts and Submarine mines in United States harbor defense, underwater minefields. The areas protected included the cities of Philadelphia, Camden, New Jersey, Camden, and Wilmington, Delaware, Wilmington along with the Chesapeake & Delaware Canal. The command originated circa 1896 as an Artillery District and became the Coast Defenses of the Delaware in 1913, with defenses initially at and near Fort Delaware on Pea Patch Island near Delaware City, Delaware, Delaware City. In 1925 the command was renamed as a Harbor Defense Command. During World War II the defenses were relocated to Fort Miles on Cape Henlopen at the mouth ...

Coastal Artillery
Coastal artillery is the branch of the armed forces concerned with operating anti-ship artillery or fixed gun batteries in coastal fortifications. From the Middle Ages until World War II, coastal artillery and naval artillery in the form of cannons were highly important to military affairs and generally represented the areas of highest technology and capital cost among materiel. The advent of 20th-century technologies, especially military aviation, naval aviation, jet aircraft, and guided missiles, reduced the primacy of cannons, battleships, and coastal artillery. In countries where coastal artillery has not been disbanded, these forces have acquired amphibious capabilities. In littoral warfare, mobile coastal artillery armed with surface-to-surface missiles can still be used to deny the use of sea lanes. It was long held as a rule of thumb that one shore-based gun equaled three naval guns of the same caliber, due to the steadiness of the coastal gun which allowed for ...

Submarine Mines In United States Harbor Defense
The modern era of defending American harbors with controlled mines or submarine mines (originally referred to as "torpedoes") began in the post-Civil War period, and was a major part of US harbor defenses from circa 1900 to 1947. Brief history In 1866, the United States Army Corps of Engineers established the Engineer School of Application at Willets Point, New York. The first commander of this school, Major Henry Larcom Abbot, was almost single-handedly responsible for designing and supervising the program of research and development that defined the strategy and tactics for the mine defense of American harbors. Abbot experimented with underwater explosives, fuzes, cabling, and electrical equipment for over a decade before publishing the first manuals on the use of mines in coast defense in 1876–77. At least one experimental controlled minefield was emplaced at this time, at Fort Mifflin in Pennsylvania. However, funding of the fortification program of the 1870s was cancell ...

Delaware Valley
The Delaware Valley is a metropolitan region on the East Coast of the United States that comprises and surrounds Philadelphia, the sixth most populous city in the nation and 68th largest city in the world as of 2020. The toponym Delaware Valley is therefore commonly used to refer to Greater Philadelphia, the Philadelphia metropolitan area, or the Greater Philadelphia Metropolitan Area. The Delaware Valley region includes portions of four U.S. states: Delaware, Maryland, New Jersey, and Pennsylvania, and four regions in Southeastern Pennsylvania, South Jersey, northern Delaware, and the northern Eastern Shore of Maryland along the central and lower Delaware River. The Delaware Valley has a total 2020 population of 6.245 million, making it the seventh largest metropolitan region in the U.S. and 35th largest metropolitan region in the world. Philadelphia is by far the largest municipality in the Delaware Valley and serves as the region's major commercial, cultural, educationa ...

''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Nieuw Nederland
New Netherland ( nl, Nieuw Nederland; la, Novum Belgium or ) was a 17th-century colonial province of the Dutch Republic that was located on the east coast of what is now the United States. The claimed territories extended from the Delmarva Peninsula to southwestern Cape Cod, while the more limited settled areas are now part of the U.S. states of New York, New Jersey, Delaware, Massachusetts and Connecticut, with small outposts in Pennsylvania and Rhode Island. The colony was conceived by the Dutch West India Company (WIC) in 1621 to capitalize on the North American fur trade. The colonization was slowed at first because of policy mismanagement by the WIC, and conflicts with Native Americans. The settlement of New Sweden by the Swedish South Company encroached on its southern flank, while its eastern border was redrawn to accommodate an expanding New England Confederation. The colony experienced dramatic growth during the 1650s, and became a major port for trade in the north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delaware Bay
Delaware Bay is the estuary outlet of the Delaware River on the northeast seaboard of the United States. It is approximately in area, the bay's freshwater mixes for many miles with the saltwater of the Atlantic Ocean. The bay is bordered inland by the states of Delaware and New Jersey, and the Delaware Capes, Cape Henlopen and Cape May, on the Atlantic. Delaware Bay is bordered by six counties: Sussex, Kent, and New Castle in Delaware, along with Cape May, Cumberland, and Salem in New Jersey. The Cape May–Lewes Ferry crosses Delaware Bay from Cape May, New Jersey, to Lewes, Delaware. The bay's ports are managed by the Delaware River and Bay Authority. The shores of the bay are largely composed of salt marshes and mudflats, with only small communities inhabiting the shore of the lower bay. Several of the rivers hold protected status for their salt marsh wetlands bordering the bay, which serves as a breeding ground for many aquatic species, including horseshoe crabs. The bay ...

Cape Henlopen
Cape Henlopen is the southern cape of the Delaware Bay along the Atlantic coast of the United States. It lies in the state of Delaware, near the town of Lewes, where the Delaware Bay meets the Atlantic Ocean. Off the coast on the bay side are two lighthouses, called the Harbor of Refuge Light and the Delaware Breakwater East End Light. Early history Cape Henlopen, originally spelled Cape Hinlopen (after its namesake Thijmen Jacobsz Hinlopen who was a prominent Dutch trader), was New Netherland's southernmost border on the 37th parallel north. In 1620, Thijmen Jacobsz Hinlopen became the business partner of Cornelis Jacobsen Mey in the now washed out Cape Cornelius and the incorrectly spelled Cape May with the ships Blijde Boodschap (English: "Good News") and Bever both of which focused on exploration and trade with the Indians on the Delaware River (then Zuidt Rivier). The area between the 38th and 40th parallels (i.e., the Delaware Bay area) as well as the Delaware River ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pea Patch Island
Pea Patch Island is a small island, approximately 1 mi (1.6 km) long, in the U.S. state of Delaware, located in the mid channel of the Delaware River near its entrance into Delaware Bay. It is a low, marshy island, located in New Castle County, facing Delaware City on the Delaware shore, and Finns Point on the New Jersey shore. Once the location of strategic military defenses, the island is currently owned by the State of Delaware as Fort Delaware State Park. The island emerged as a mud bank in the river in the 18th century. According to folklore, the island received its name after a ship full of peas ran aground on it, spilling its contents and leading to a growth of the plant on the island. In the 1790s, Pierre L'Enfant suggested the use of the island as part of the defenses of New Castle, Delaware and Philadelphia. During the War of 1812, a seawall and dykes were built on the island, with a view to building a Martello tower there.Dobbs, Kelli W., Rebecca J. Siders. ''F ...

Fort Delaware
Fort Delaware is a former harbor defense facility, designed by chief engineer Joseph Gilbert Totten and located on Pea Patch Island in the Delaware River.Dobbs, Kelli W., et al. During the American Civil War, the Union used Fort Delaware as a prison for Confederate prisoners of war, political prisoners, federal convicts, and privateer officers. A three-gun concrete battery of 12-inch guns, later named Battery Torbert, was designed by Maj. Charles W. Raymond and built inside the fort in the 1890s. By 1900, the fort was part of a three fort concept, the first forts of the Coast Defenses of the Delaware, working closely with Fort Mott in Pennsville, New Jersey, and Fort DuPont in Delaware City, Delaware. The fort and the island currently belong to the Delaware Department of Natural Resources and Environmental Control (DNREC) and encompass a living history museum, located in Fort Delaware State Park.

Chesapeake & Delaware Canal
The Chesapeake & Delaware Canal (C&D Canal) is a -long, -wide and -deep ship canal that connects the Delaware River with the Chesapeake Bay in the states of Delaware and Maryland in the United States. In the mid‑17th century, mapmaker Augustine Herman observed that these great bodies of water were separated only by a narrow strip of land. In 1764, a survey of possible water routes across the Delmarva Peninsula was made, but little action followed. The idea was raised again in 1788 by regional business leaders, including noted Philadelphians Benjamin Franklin and Benjamin Rush. Despite the beginnings of a commercial venture in 1802—coincident with Canal Mania in England and Wales—it wasn't until 1829 before the C&D Canal Company could, at last, announce the waterway "open for business". Its construction cost of $3.5 million (equivalent to $ million in ) made it one of the most expensive canal projects of its time. In the present era, the C&D Canal is owned and operat ...
