Sybil Ludington was an alleged heroine of the American Revolutionary War, though modern accounts dispute this. On April 26, 1777, at age 16, Ludington, the daughter of a colonel in the Colonial militia, Henry Ludington, is said to have made an all-night horseback ride 40 miles (64 km) to rally militia forces in neighboring towns after the burning of Danbury, Connecticut, by British forces.

Henry Ludington was an American soldier in the American Revolutionary War. He aided the effort by providing spies and was associated with John Jay in a ring of spies.
