Endorsement Concerning Daniel Coyle 
If this man's Colonel will say in writing on this sheet that he is willing to receive him back to his regiment, I will discharge & send him. A. LINCOLN
Dec. 29. 1864.
 Lincoln's endorsement appears on a letter from Daniel Coyle, Company K, Fifth New York Heavy Artillery, December 26, 1864. Coyle was arrested for desertion on June 6, 1864, returned to duty during July and August, and tried by court-martial on November 21. Coyle's letter, written from Old Capitol Prison, carries no endorsement by ``this man's Colonel.''
