Horace Greeley, one of the "Secret Six" who funded John Brown's raid on Harper Ferry, was, needless to say, a radical abolitionist, pro Civil War, and had no tolerance for the Confederacy. 

That said, he was for the just treatment of all men. When Jefferson Davis, former President of the Confederacy, had been captured and held for over a year in Richmond without even the beginning of a trial, Greeley took to the press to demand that Davis either be tried or released. This was both an act of justice toward Davis and an act of reconciliation, knowing that the South needed closure to begin healing. When he was not released, Greeley showed up in Richmond himself, paid the $100,000.00 bail, and escorted him out of the prison. It was a moment of solidarity that signaled that Southerners would continue to be treated as Americans and afforded the same rights as all Americans; the War was over.
