Slaves could not wear uniforms and carry carbines.  Mr. Lee saved Washington's life
several times.  And, why don't we know what color Mr. Lee's horse is since
he was almost as famous as Washington's horse, Nelson?

Sometimes Mr. Lee's uniform was fancier than Commander-in-Chief's uniform which
Washington applauded.

Here Mr. Billy Lee is celebrating the British Surrender at Yorktown.
