Washington had a slave batman whom he kept all through the Revolutionary war.
> William "Billy" Lee (1750–1828), also known as Will Lee, was George Washington's personal assistant and the only one of Washington's slaves freed immediately by Washington in his will. Because he served by Washington's side throughout the American Revolutionary War and was sometimes depicted next to Washington in paintings, Lee was one of the most publicized African Americans of his time.
Washington freed them only after his death and from what I know that didn’t work that well either so a lot of them remained slaves. In what way did Virginia force Jefferson to keep slaves?
