The Battle of Harlem Heights was a skirmish in the New York Campaign of the American Revolutionary War. It was fought in what is now the Morningside Heights and west Harlem neighborhoods of Manhattan in New York City on September 16, 1776. About 70 were killed on each side, including the American Captain Thomas Knowlton . Although the battle was generally inconclusive, it served to restore confidence among the Continental forces who had been routed the day before during the Landing at Kip's Bay.
