Battle of Harlem Heights in the context of Nathanael Greene

The written history of New York City begins with the arrival of the first European explorer to the area, Italian Giovanni da Verrazzano in 1528 and his brief interactions with the Indigenous Lenape. European settlement began with the Dutch in 1608 and New Amsterdam was founded with the assistance of the Lenape in 1624.

The "Sons of Liberty" campaigned against British authority in New York City, and the Stamp Act Congress of representatives from throughout the Thirteen Colonies met in the city in 1765 to organize resistance to Crown policies. The city's strategic location and status as a major seaport made it the prime target for British seizure in 1776. General George Washington lost a series of battles from which he narrowly escaped (with the notable exception of the Battle of Harlem Heights, his first victory of the war), and the British Army occupied New York and made it their base on the continent until late 1783, attracting Loyalist refugees.

The New York and New Jersey campaign in 1776 and the winter months of 1777 was a series of American Revolutionary War battles for control of the Port of New York and the state of New Jersey, fought between British forces under General Sir William Howe and the Continental Army under General George Washington. Howe was successful in driving Washington out of New York, but overextended his reach into New Jersey, and ended the New York and New Jersey campaign in January 1777 with only a few outposts near New York City under British control. The British held New York Harbor for the rest of the Revolutionary War, using it as a base for expeditions against other targets.

Landing unopposed on Staten Island on July 3, 1776, Howe had assembled an army that included components that had withdrawn from Boston in March following the British failure to hold that city, combined with additional British troops, and Hessian troops hired from several German principalities. Washington's Continental Army included New England soldiers and regiments from the Thirteen Colonies as far south as the Colony of Virginia. Landing on Long Island in August, Howe defeated Washington in the largest battle of the war in North America, but the Continental Army was able to regroup and make an orderly and covert retreat to Manhattan that night under a cover of darkness and fog. Washington suffered a series of further defeats in Manhattan but prevailed in a skirmish at the Battle of Harlem Heights and eventually withdrew his troops successfully to White Plains, New York. Howe, meanwhile, returned to Manhattan and captured those forces Washington had left on the island.
