Well, Non-Sequitur had the issue and linked me to it.
GOP had posted it a while back.
Capitan-Refugio, I believe does accept the validity of the papers.
However, the attacks that you and your Paleo-Confederate friends have been launching on Lincoln as being the author of the plot to kill Davis is not supported by the author of the article himself.
To be sure, there is no certain evidence tying Edwin Stanton to the Kilpatrick-Dahlgren plot. Only the fact of their February 12 meeting can be documented. Yet no other reasonable explanation meets the case. It cannot be imagined that Kilpatrick had the courage to carry this out on his own without sanction, and only Stanton could have filled such an approving role. It certainly cannot be imagined that the president countenanced political assassination and black flag warfare against civilians. Lincoln approved the capture of Davis, perhaps as a hostage for the release of Union prisoners, but nothing we know about the man suggests he would have gone beyond that.
The author believes that Stanton, not Lincoln may have talked about killing Davis.
And regarding Stanton, it is still only conjecture on his part.
Whether it was Lincoln OR Stanton, doesn't make a difference. If The Feds attempted to have Davis killed, they lost any & all moral high ground, and the Confederates were justified in doing what was done.
