Long ago, and I have definitely forgotten the name, but I believe I read that years after the trial one of the members of the Military Commission expressed his belief that Mary Surratt was the second most guilty of those tried (only after John Wilkes Booth in terms of overall guilt). Possibly this opinion was privately conveyed to Johnson, and he simply became convinced she was so guilty he simply had to let the execution go through?
