There is something wrong with this story.
Patton’s driver was Sergeant John Lyman Mims of Abbeville, Alabama.
His wife worked at the probate judge’s office in Abbeville. I talked to her as I used to search records there.
In one of the books they mentioned that Mims had gone home at the time of Patton’s fatal accident. It even mentione that Mims had driven him for four years with no accidents.
...
My pediatrician said he was Patton’s driver. He wasn’t any of these guys. I’ve tried to verify it, but couldn’t. Maybe he had many drivers, or it could be anybody who drove him once would claim it, since Patton was famous.
I agree. What bothers me is the statement that there are no pictures because it was "against regulations."
I guess only the Army could say for sure. A quick internet search turns up perhaps a dozen names for “who drove for Patton” during WWII. Sanza only claims from May ‘44–May ‘45.
