I've converted the file I obtained from the National Archives to two pdfs and uploaded them to Scribd.

The testimony is at http://www.scribd.com/doc/28885702/Bradley-Court-Martial-Testimony

Bradley's written defense is at http://www.scribd.com/Bradley-s-Defense/d/28885807

Bradley's defense is pretty hard to read - his counsel didn't have pretty handwriting like the clerk who took down the testimony.

Hoping this may be of some use to someone.
