On June 3, 1781, Jack Jouett rode to Monticello to warn Thomas Jefferson of a British attack. From the article:
"but he wasn’t the only one to make a daring late-night ride to warn that the British were coming. In 1781, during the Revolutionary War (and six years after Revere’s ride), a 26-year-old Virginian, John “Jack” Jouett, made a dangerous, 40-mile dash on horseback to Monticello, the home of Virginia Governor Thomas Jefferson, to sound the alarm that British forces were on the way to capture the Founding Father. Thanks to Jouett, later dubbed the Paul Revere of the South, Jefferson managed to escape and avoid being taken prisoner.
On the evening of June 3, 1781, Jouett was at a Virginia tavern when he spotted Lt. Colonel Banastre Tarleton nearby with 250 British troops. Jouett realized that Tarleton and his men were headed toward Charlottesville, where Virginia’s General Assembly was temporarily convening. The Assembly had moved there after the capital, Richmond, was attacked by British forces, led by recent defector Benedict Arnold. Tarleton planned to capture many leading Virginian politicians, including Richard Henry Lee, Patrick Henry and Thomas Jefferson, whose estate was just outside of Charlottesville."
