Let me make it clear that I firmly believe that if tried Davis would have been convicted. Not other verdict would have been possible. Personal feeling about his guilt aside, packing a jury was as well known a tactic in 1869 as it is today and there is no way that the government's prosecutors would have taken a chance on acquittal. Even in Virgina they would have found men who would have convicted and Davis would have gone to jail. Chase saved him from that. So the idea that a trial would have somehow vindicated secession is wishful thinking.
Dana's letter to Ewarts suggests that he wouldn't have stooped to pack a jury.
Don't forget that this same Lincoln who is lashed so badly by some of FR absolutely refused to consider treason trials for Davis or anyone else. Oddly, the best place I know of to see this re-enacted in a movie is in the Turner production about Booth. Lance Henrickson (who bore an eerily close resemblance to Lincoln) is seen pounding on the table, "No,no,no," to Stanton's demand for treason trials.
But there is little doubt, given the way Stanton railroaded the assasination conspirators, that he could have had Davis, Lee and the whole crew up on the scaffold soon after Lincoln's death, if he had so chosen.
Lincoln was a man with a great heart. He was -always- as he said, willing to forgive on the basis of Christian charity.
And yet the smear campaign proceeds.
