Abraham Lincoln actually said...
I do hereby notify them that all deserters who shall, within sixty days from the date of this proclamation, viz, on or before the 10th day of May, 1865, return to service or report themselves to a provost-marshal shall be pardoned, on condition that they return to their regiments and companies or to such other organizations as they may be assigned to and serve the remainder of their original terms of enlistment and in addition thereto a period equal to the time lost by desertion.
