On This Day: A panic spreads throughout New York as rumors fly that British ships are within sight

The following is an installment of “On This Day,” a series celebrating America’s 250th anniversary by following the actions of Gen. George Washington, the Continental Congress, and the men and women whose bravery and sacrifice led up to the signing of the Declaration of Independence.

May 19, 1776

A panic reverberates throughout New York City as word spreads that British ships have been sighted off the coast. 

It is a rumor that hardens patriots, emboldens loyalists, and is ultimately false. However, it spurs Gen. George Washington into formalizing an alarm system so that when the inevitable happens, he, along with the soldiers, citizens, and loyalists who would rise up and join the British Army, would know that the day had come.

The alarm system was simple but effective. By day, two cannons from Fort George and a flag over headquarters. By night, the same cannon signal with lanterns raised. 

Washington then orders his troops to be drilled on where their regiment should assemble and how to respond to the attack.

Washington is also strident in ordering readiness. Each soldier will be properly equipped, and every musket on hand must be in working order.

In the end, the false sighting of the British ships becomes a gift, instigating a much-needed rehearsal.

Washington sends a note to the President of the Second Continental Congress, John Hancock.
