In early 1776, the colony of Connecticut commissioned the construction of a fort on a point of rock that stretched out into the harbor to protect the port of New Haven from the British. This was the location of an earlier unnamed fort from circa 1657, and on this site was erected Black Rock Fort. Unfortunately for the colonists, in 1779 British General William Tryon, during his raid of Connecticut coastal communities, captured Black Rock Fort along with its nineteen defenders, but only after they had run out of ammunition. The British burned the barracks as they left. In 1807-1812, the abandoned fort was reconstructed with six guns as Fort Nathan Hale under the second system of US fortifications, and it served to defend the port from the British once again during the War of 1812.

Supposedly named by Washington as Fort Necessity or Fort of Necessity, the structure protected a storehouse for supplies such as gunpowder, rum, and flour. The crude palisade they erected was built more to defend supplies in the fort's storehouse from Washington's own men, whom he described as "loose and idle", than as a planned defense against a hostile enemy.

a fortification protecting Plantation Number 4, the northernmost British settlement along the Connecticut River in New Hampshire until after the French and Indian War. Number 4 was one of 32 towns established on the same day through the Massachusetts Bay Colony.
