FILE XXVIII.
Statements: Jeremiah Artis, a real deserter from the Confederates—William J. Bradley, an honest refugee—Charles E. Langley, an official Confederate spy—Langley, personating a correspondent of the New York "Tribune," was a most successful and dangerous spy.
I have told you that it required experience and skill to determine who were honest deserters, sick of the Confederate service, and seeking homes in our lines, or who were refugees, entitled to a refuge, or who were spies. Under the head of spies were placed those who came North to visit friends, or gain a remount intending to return to the Confederate lines; these latter were not being especially employed as spies, but they were persons who might carry valuable information. But it was the real official spy that we were after.
By a "remount" I mean those who were granted leave of absence by the Confederates for the purpose of remounting. These were mounted men who having lost their horses, were given a "remount pass" which was practically authority to come within our lines and gain a horse by any means; therefore without desire to weary you I will give you the examinations of one of each class, to wit: Jeremiah Artis, a real deserter; Wm. J. Bradley, a refugee; Charles E. Langley, one of the most expert and successful official spies, who is the one I referred to in the Emmerich case as the "pal" of the conductor on the Baltimore and Ohio railroad.
