To John M. Clayton 
Dear Sir: May 16. 1849
I learn that E. P. Oliphant, of Union Town, Pa. is a candidate for the appointment of Charge to Denmark. Several years ago Mr. Oliphant was a citizen of our town, and was a fellow soldier with us in the ``famed Black Hawk War.'' His success would afford me sincere satisfaction. Your Obt. Servt. A. LINCOLN
 ALS, DNA FS RG 59, Appointment Papers. Ethelbert P. Oliphant wrote Lincoln from Union Town, Pennsylvania, on May 8, ``I have the pleasure to be informed by your letter of Jany 24th ult. that it will afford you great pleasure to aid me in the matter I have in view, to wit the charge to Denmark. That aid would come very seasonably at this time, as I am about to visit Washington City, to see something in relation to that matter. If you and Mr Stuart could feel at liberty to do me the favour to write to Genl. Taylor & forward it to him or the Secy of State direct from your place you will place me under lasting obligations.'' (DLC-RTL). Lincoln's letter of January 24, 1849, is presumably not extant. No record has been found of Oliphant's appointment.
