A rumor that British ships had been sighted off the coast spread through New York City on May 19, 1776. The report proved false but caused immediate concern among residents. The alarm system used two cannons fired from Fort George and a flag raised over headquarters during daylight.

At night, the cannons were fired and lanterns were raised to signal the approach of enemy forces. Gen. George Washington ordered troops to drill on assembly points and response procedures. He also directed that every soldier be properly equipped and that all muskets be kept in working order.

Washington sent a letter to John Hancock, president of the Second Continental Congress, outlining the situation. The letter was delivered by an officer traveling to Philadelphia. The false alarm served as a rehearsal for the defense of the city.

Washington viewed the episode as preparation for the expected arrival of British forces.
