"I think it was PBS that did a fiction account called "The Trial of General Custer" ..."

The book (author: Douglas C. Jones) was far superior to the "movie".
In the book, the CMOH was given in exchange for Custer's resignation from the Army (as, in the book, he was acquitted of the Charges and so was able to remain in the Army).

In the book, as well, it does a far better job of explaining that, as a result of the Little Bighorn Battle, he was insane.

I doubt somebody like Custer would go insane over losing Troopers. If he was that easily pushed over the edge, it would have happened during the Civil War in my opinion, not 15 years later in South Dakota.

Interesting premise though.
