I am sure you can find a lot about him.
It isn't Politically Correct to point out that he was relieved of command, but I am sure you can find out why if you search.
I do not know the details off the top of my head, but it has something to do with the Bosnian thing, which was done by NATO.
I would have to search, so it is "an excersize left to the students."
Before Clark ran for the nomination he was asked by Crissy Matthews on his show why he was relieved of command, Clark about had a heart attack. He finally said he just retired early. It was hilarious.
