Lydia Darragh: The Pacifist Quaker Who Spied for the American Revolution

cultural-heritage · 2026-03-21

During the American Revolution, Lydia Darragh, an Irish immigrant and pacifist Quaker living in Philadelphia, overheard British officers planning a surprise attack on George Washington's troops at Whitemarsh in December 1777. Despite her religious commitment to nonviolence, Darragh crossed British lines under the pretense of fetching flour to warn the Continental Army. Her warning helped Washington prepare for the British advance, which ultimately failed. Historian Robert N. Fanelli's 2025 book verifies Darragh's story through archival research, though some embellished accounts exist. Darragh was later removed from the Quaker community for her actions but remains buried at Philadelphia's Arch Street Meeting House.
