This situation created the perfect situation for Lydia Darrah to learn what plans the British were discussing.

In December, the British held a secret meeting in her home whenshe and her family were to be asleep. Darrah eavesdropped and learned that the British intended to attack Washington’s troops in White Marsh.

She determined to get word of the attack to Washington. By gaining a pass as a homemaker needing flour from the mill, Darrah walked past British soldiers to smuggle a message to Boudinot who got it to Washington. Because of the warning, Washington’s troops were prepared, the battle was a standoff, and the British returned to Philadelphia. Though questioned by the British, she held to her story that all were sleeping and heard nothing.

Lydia Darrah died on December 28, 1789, and was buried in Philadelphia.
