"Liberty or Death" - Liberty Kids

Context: James, Sarah, Moses, and Henri travel to Williamsburg, Virginia to get a new printing press. While in Williamsburg they come across a slave auction block where Moses sees his brother, Cato, being sold on the auction block. Then Moses attempts to buy his brother, but the people will not let him because they do not believe his letter of freedom from Benjamin Franklin is worth anything.  They travel to Richmond, Virginia for Patrick Henry’s speech and for Moses to go to the Abernathy Plantation for his brother.

Consider this: Does the fact that the British are offering slaves freedom for fighting on their side change how you look at the British as the enemy of the colonists?
