August 1776

On August 2nd John Hancock, the President of the Congress, signed the engrossed copy with a bold signature. The other delegates, following custom, signed beginning at the right with the signatures arranged by states from northernmost New Hampshire to southernmost Georgia. Although all delegates were not present on August 2nd, 56 delegates eventually signed the document. Late signers were Elbridge Gerry, Oliver Wolcott, Lewis Morris, Thomas McKean, and Matthew Thornton, who was unable to place his signature with the other New Hampshire delegates due to a lack of space. Some delegates, including Robert R. Livingston of New York, a member of the drafting committee, never signed the Declaration.s

George Washington and the Continental Army arrived in New York City on April 13, 1776, after marching south from Boston following the British evacuation.  He and his vanguard arrived in Manhattan (crossing King's Bridge into the Bronx) to begin fortifying the city against expected British attacks. 

Lower Manhattan: The actual built-up town covered only the southern portion of Manhattan Island, stretching from the Battery north to around present-day Chambers Street and City Hall Park.

The Rest of the Island: Beyond the densely packed colonial port, the rest of Manhattan Island consisted mostly of independent farms, rolling hills, marshes, and small settlements like Harlem further north. 

The entire city had a population of roughly 25,000 people living in low-rise timber and brick buildings.

George Washington stationed and moved parts of his Continental Army to fortify Brooklyn Heights on Long Island i

By nightfall of August 27, 1776, George Washington and his troops were badly beaten and trapped in the area of Brooklyn Heights.

After the American defeat, Washington gathered his generals at a mansion on the heights to plan their next move, ultimately executing a brilliant, fog-covered nighttime evacuation of 9,000+ troops across the East River to Manhattan. AI's synopsis of the evacuation:

1. The Assembly & March Down the Bluff

Under strict orders of complete silence, roughly 9,000 Continental soldiers were quietly pulled from the active trenches along the Brooklyn Heights ridge. They marched down the steep bluff via what was then called Old Ferry Road (today’s Old Fulton Street).

2. The Launch Point: Brooklyn Ferry Landing

The troops arrived at the Brooklyn ferry slip, located exactly where the Fulton Ferry Landingstands today (directly under the shadow of the modern Brooklyn Bridge).

• The Operators: Colonel John Glover’s Marblehead Regiment—a unit composed entirely of skilled fishermen and sailors from Massachusetts—manned a confiscated fleet of flat-bottomed bateaux, rowboats, and sail-rigged ferries. 
• The Friction: A fierce northeast wind and roaring river currents initially made rowing nearly impossible. The oarsmen had to muffle their oarlocks with cloth to keep the nearby British forces from hearing the movement. 

3. The Crossing

The boats navigated approximately 0.4 miles (roughly 700 yards) northwest across the treacherous, swirling waters of the East River. Around 2:00 AM, the wind shifted favorably, allowing the evacuation to speed up just as a dense "providential" fog rolled in to completely shield them from British view.

4. The Landing Site: Manhattan

The boats landed on the Manhattan side at the Fulton Slip (often historically referred to as the Fly Market slip).

• Modern Coordinates: This exact landing spot sits at the intersection of Fulton Street and South Street, right next to the historic South Street Seaport and the FDR Drive.
• Once ashore, the exhausted troops marched a few blocks inland toward the commons (modern-day City Hall Park) to reorganize, completely out of reach of British clutches.

George Washington famously refused to board a boat until the bulk of his army had crossed. He stepped into one of the final structures just as the morning sun began burning away the fog, leaving the British to discover empty trenches.
