Answer :
John Murray, Earl of Dunmore and royal governor of Virginia issued a proclamation in the fall of 1775 granting freedom to the slaves of rebels who were willing to take up arms in the British army.
Virginia's royal governor and earl of Dunmore, John Murray, issued a threat in April 1775 that if the colonists defied British rule, he would release the slaves and burn down the city of Williamsburg. Dunmore's situation grew more precarious in the months that followed. Only 300 men remained in his army, and on June 8 he fled Williamsburg's Governor's Palace for safety on a British ship out of fear of being assaulted.
Dunmore issued a proclamation on November 7, 1775, declaring martial law and granting freedom to slaves who would leave patriotic owners and join in the British army.
300 black men enlisted in Dunmore's "Royal Ethiopian Regiment" within a month. His declaration encouraged thousands of slaves to seek freedom behind British lines throughout the Revolutionary War, even though the regiment only increased in size to 800 men.
