The Battle of Brooklyn (also known as the Battle of Long Island) on August 27, 1776, was the Revolutionary War’s largest engagement, involving more than 40,000 troops, including 400 Royal Navy ships and 32,000 British soldiers under Admiral Richard Howe. It followed the signing of the Declaration of Independence and posed a significant challenge for George Washington’s Continental Army, which was trapped in Brooklyn Heights. The Americans shrewdly evacuated 9,000 soldiers to Manhattan at night via flat-bottomed ferries, allowing the British to control New York’s ports for the rest of the war. Even today, five Army National Guard units and one Army Field Artillery Battalion trace their origins to this battle.
