Mr. Brannon,
You can find the information on COL Glenn's Court Martial in his Compiled Military Service Record (CMSR) that is available through this web site (flashing graphic at the top cneter of the page). His CMSR holds an immense amount of detail on the charges specifications.
Respectfully,
Gerald D. Hodge, Jr.
