War of 1812 [SEP] Freeing and recruiting slaves
The British Royal Navy's blockades and raids allowed about 4,000 African Americans to escape slavery by fleeing American plantations aboard British ships. American slaves near to the British military rebelled against their masters and made their way to British encampments. The migrants who settled in Canada were known as the Black Refugees. The blockading British fleet in the Chesapeake Bay received increasing numbers of freed slaves during 1813. By British government order, they were considered free persons when they reached British hands. Alexander Cochrane's proclamation of 2 April 1814 invited Americans who wished to emigrate to join the British. Although it did not explicit mention slaves it was taken by all as addressed to them.
