British proclamation to free, and protect any slave who escaped a non-loyalist plantation
Explanation:
In June, 1779, (British) General Henry Clinton made a proclamation; all slaves who escaped the plantation they worked on (if it was owned by an enemy of the UK), and made it to New York City (during British occupation) was to be immediately freed, and protected, in addition, units were set up for Black men.
John Burgoyne, poet, playwright and British general, submits an ill-fated plan to the British government to isolate New England from the other colonies on January 28, 1777.
