The Philipsburg Proclamation is a historical document issued by British Army General Sir Henry Clinton on June 30, 1779 intended to encourage slaves to run away and enlist in the Royal forces. The proclamation extended the scope of Dunmore's Proclamation, issued four years earlier by Virginia's last Royal governor, Lord Dunmore, granting freedom to slaves in Virginia willing to serve the Royal forces. The new document, issued from Clinton's temporary headquarters at the Philipsburg Manor House in Westchester County, New York, proclaimed all slaves in the newly established United States belonging to American Patriots free, regardless of their willingness to fight for the Crown. It further promised protection, freedom and land to any slaves who left their master.
