Long Island, battle of
battle of Long Island, Aug. 27, 1776, American defeat in the American Revolution. To protect New York City and the lower Hudson valley from the British forces massed on Staten Island, George Washington sent part of his small army to defend Brooklyn Heights, on Long Island. After several unsuccessful peace overtures, Sir William Howe landed at Gravesend while the British fleet under his brother, Richard Howe, shelled New York. After Sir William's troops defeated an American force under John Sullivan and William Alexander (Lord Stirling), Israel Putnam, the corps commander, prepared for the main attack. Sir William, not wanting another Bunker Hill, decided to lay siege instead of storming Brooklyn Heights. Washington saw the position was hopeless and evacuated (night of Aug. 29–30) his army back to Manhattan. Shortly afterward, the Americans began the retreat northward in which delaying actions were fought at Harlem Heights, White Plains, and Fort Washington. Washington managed to extricate most of his troops, and he regrouped them before striking at Trenton.
