George Washington’s evacuation across the East River after the Battle of Long Island.
Historical background
On 27 August 1776, British troops outflanked Washington’s army and pushed it back to Brooklyn Heights. With the East River at his rear and British forces nearby, Washington faced the possible loss of much of his army.
During the night of 29–30 August, boat crews ferried soldiers, horses and equipment across to Manhattan. Fog concealed the final movements. The retreat preserved the army for the rest of the campaign.
