Ah. Thank you. A bit more nuanced but still NOT Ulysses S. Grant’s slaves, which is a (false) point liberals often bring to the table in this discussion.
Both Grant and George Thomas owned slaves. Grant’s father in law gave him a young male slave. Grant owned the man for about a year then gave that person his freedom. This was several years before the war. Thomas bought a young lady in 1858 to help his wife around the house. He retained ownership of this slave until the XIII Amendment was ratified. Then kept her on for pay.
