The foreign national man who was a Federal park guide was very kind to explain to me that Washington's slaves were kept in the hot attic of his headquarters. He did not seem to know much about the Revolution aside from that. That was one of the only things he seemed to know. (I guess when he retires at age 40, he can spit on Washington's face every month when he gets his checks cashed from his federal pension for sitting on his butt.)
I left the Headquarters of the Slave Master at Valley Forge and saw the guard shacks for Washingtons personal guards. A sign there stated that they had to be native Americans. I found out later that there was a plot by Washington's guards to kill him, and it was hatched by an Irish man who was a guard. I think he was hung in New York. After that event, the Slave Master from Virginia was very cautious with foreign born people with guns. So on my visit to Mt. Vernon, aside from learning that our Founder was viewed by some foreigners as a low life Slave Master scum, he thought some foreigners were low life scum that would try to kill him and his new country. In a word, Ironic.
That is an excellent bit of information! I wonder if there is an account of it in a book somewhere?
