The largest battle of the American Revolution was a tactical disaster for George Washington.
Fought on August 27, 1776, the Battle of Long Island saw the British trap the Continental Army through a brilliant, secret flanking maneuver. While history often focuses on the final retreat, the brutal, overlooked combat at Battle Hill accounted for the highest concentration of British casualties in the entire engagement.
Following the British evacuation of Boston in March 1776, George Washington anticipated an attack on New York City. He moved his forces south, fortifying Brooklyn Heights and Manhattan. By August, General William Howe had amassed 32,000 troops on Staten Island. Washington, fearing a diversion, split his army, leaving only 6,000 men to defend the strategic heights of Brooklyn against a vastly superior force.
The British victory hinged on a clandestine night march. While General James Grant launched a noisy diversionary attack along the Gowanus Road, 10,000 British troops under General Henry Clinton bypassed the American lines entirely by slipping through the unguarded Jamaica Pass. By dawn on August 27, the British had successfully flanked the American positions. The resulting panic led to significant losses, though a desperate stand by Maryland and Delaware troops allowed many to escape to the main defenses at Brooklyn Heights.
Much of the fighting's intensity occurred at Battle Hill, the highest point in Kings County. Here, a small force led by Brigadier General Samuel Holden Parsons held the summit for three hours against repeated counterattacks, inflicting over 40% of the total British deaths for the day. Despite this tactical ferocity, the Americans were eventually surrounded and overwhelmed. Washington, realizing the position was untenable, executed a brilliant, silent evacuation of his entire army to Manhattan on the night of August 29–30, preserving his force to fight another day.
The battle remains a study in intelligence failure and tactical maneuver. Washington’s inability to secure the Jamaica Pass and his misinterpretation of British movements nearly ended the revolution in its infancy. Yet, the successful withdrawal across the East River remains one of the most significant logistical feats of the war, preventing the total capture of the Continental Army.
