As governor of Virginia for two years during the Revolution, Jefferson signed a bill to promote military enlistment by giving white men land, "a healthy sound Negro...or £60 in gold or silver."  As was customary, he brought some of his household slaves, including Mary Hemings , to serve in the governor's mansion in Richmond. In the face of British invasion in January 1781, Jefferson and the Assembly members fled the capital and moved the government to Charlottesville, leaving Jefferson's slaves behind. Hemings and other slaves were taken as British prisoners of war; they were later released in exchange for British soldiers. In 2009, the Daughters of the Revolution (DAR) honored Mary Hemings as a Patriot , making her female descendants eligible for membership in the heritage society.
