On August 22, Howe’s large army landed on Long Island, hoping to capture New York City and gain control of the Hudson River, a victory that would divide the rebellious colonies in half. On August 27, the Red Coats marched against the Patriot position at Brooklyn Heights, overcoming the Americans at Gowanus Pass and then outflanking the entire Continental Army. Howe failed to follow the advice of his subordinates and storm the redoubts at Brooklyn Heights, and on August 29 General Washington ordered a brilliant retreat to Manhattan by boat, thus saving the Continental Army from capture. At the Battle of Brooklyn, the Americans suffered 1,000 casualties to the British loss of only 400 men. On September 15, the British captured New York City.
