Question

Witch prominent American leader encouraged the use of African American slaves during the revolution war

Answer 1

In December of 1775  George Washington wrote a letter to Colonel Henry Lee III, in which he stated the tide of war would be decided by which army could armed the "blacks" the fastest.

This measure was taken right after Lord Dunmore's (at the time Royal Governor of Virginia) proclamation of providing freedom to the slaves if they fought for the loyalist army, and so in fear that some of the black soldiers would turn to the other side George Washington issued orders to reenlist in the all the free blacks who had already served in the army.

In 1776 Congress agreed to Washington's orders and allowed all blacks who had served in the army to reenlist.
