A naval mine is a self-contained explosive device placed in water to damage or destroy surface ships or submarines. Unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel or a particular vessel type, akin to anti-infantry or anti-vehicle mines. Naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vessels and create "safe" zones. Mines allow the minelaying force commander to concentrate warships or defensive assets in mine-free areas giving the adversary three choices: undertake an expensive and time-consuming minesweeping effort, accept the casualties of challenging the minefield, or use the unmined waters where the greatest concentration of enemy firepower will be encountered.
The Battle of Heligoland Bight was the first Anglo-German naval battle of the First World War, fought on 28 August 1914, between ships of the United Kingdom and Germany. The battle took place in the south-eastern North Sea, when the British attacked German patrols off the north-west German coast. The German High Seas Fleet was in harbour on the north German coast while the British Grand Fleet was out in the northern North Sea. Both sides engaged in long-distance sorties with cruisers and battlecruisers, with close reconnaissance of the area of sea near the German coast—the Heligoland Bight—by destroyer.
A warship or combatant ship is a ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a nation. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations.
Turtle was the world's first submersible vessel with a documented record of use in combat. It was built in 1775 by American David Bushnell as a means of attaching explosive charges to ships in a harbor, for use against the Royal Navy during the American Revolutionary War. Connecticut Governor Jonathan Trumbull recommended the invention to George Washington, who provided funds and support for the development and testing of the machine.
David Bushnell , of Westbrook, Connecticut, was an American inventor, a patriot, a teacher, and a medical doctor.
USS Providence was a sloop-of-war in the Continental Navy, originally chartered by the Rhode Island General Assembly as Katy. The ship took part in a number of campaigns during the first half of the American Revolutionary War before being destroyed by her own crew in 1779 to prevent her falling into the hands of the British after the failed Penobscot Expedition.
Alfred was the merchant vessel Black Prince, named for Edward, the Black Prince, and launched in 1774. The Continental Navy of what would become the United States Navy acquired her in 1775, renamed her Alfred after 9th century English monarch Alfred the Great, and commissioned her as a warship. She participated in two major actions, the battle of Nassau, and the action of 6 April 1776. The Royal Navy captured her in 1778, took her into service as HMS Alfred, and sold her in 1782. She then became the merchantman Alfred, and sailed between London and Jamaica.

The Pennsylvania Navy served as the naval force of Pennsylvania during the American Revolution and afterward, until the formation of the United States Navy. The navy's vessels served almost exclusively on the Delaware River, and were active in first defending the approaches to the city of Philadelphia during the British campaign that successfully occupied the city in 1777, and then preventing the Royal Navy from resupplying the occupying army.
USS Sumner (AG-32/AGS-5) was a survey ship in the United States Navy. She was named in honor of Thomas Sumner. She was originally commissioned as a submarine tender as USS Bushnell (AS-2/AG-32), in honor of David Bushnell, the inventor of the first American submarine.
The Chesapeake Bay Flotilla was a motley collection of barges and gunboats that the United States assembled under the command of Joshua Barney, an 1812 privateer captain, to stall British attacks in the Chesapeake Bay which came to be known as the "Chesapeake Campaign" during the War of 1812. The Flotilla engaged the Royal Navy in several inconclusive battles before Barney was forced to scuttle the vessels themselves on August 22, 1814. The men of the Flotilla then served onshore in the defense of Washington, DC and Baltimore. It was disbanded on February 15, 1815, after the end of the war.

A British and Hessian force was sent to take Fort Mercer on the left bank of the Delaware River just south of Philadelphia, but was decisively defeated by an inferior force of colonial defenders. Although the British did take Fort Mercer a month later, the victory supplied a sorely-needed morale boost to the American cause, delayed British plans to consolidate gains in Philadelphia, and relieved pressure on General George Washington's army to the north of the city.
