WORLD HISTORY

Detailed explanation-1: -Many slaves became free through manumission, the voluntary emancipation of a slave by a slaveowner. Manumission was sometimes offered because slaves had outlived their usefulness or were held in special favor by their masters. The offspring of interracial relations were often set free.

Detailed explanation-2: -Many African Americans, both enslaved and free, wanted to join with the Patriots. They believed that they would achieve freedom or expand their civil rights. In addition to the role of soldier, Black men also served as guides, messengers, and spies.

Detailed explanation-3: -Both free and enslaved men fought for American independence and for the British attempt to squash the rebellion. Most black Americans supported the British for reasons we know, but many served with the Continental Army because they believed in what the revolution presumably stood for.

Detailed explanation-4: -To fill their quotas, they began allowing enslaved people and free African-Americans to enlist. In return, slaves were promised their freedom for their service. By 1781, the Continental army was noted as being nearly one-forth African-American at Yorktown.
