“With this in view, and to give the enemy greater confidence in him, information of great seeming value was, by consent of the French, given him to convey to the Germans. Then he told the head of the German secret service, that he had a brother through whom he had gained the important information which he had given to them. The Germans, meanwhile, knew that he professed when in the Allied lines to be a spy for them. Adolph also suggested that I be encouraged to desert to the German lines. But the hard-headed chief of their secret service thought I could serve them better by remaining where I was. It was not until he had convinced them that I was in danger of arrest, and that the Americans might obtain information from me that would impair my brother’s usefulness as an agent of their secret service, that they consented to his plans. “It was a bitter thing for me to leave you to believe that I was a traitor, and I did not take the course I did until convinced that it was needful for General Foch to have more intimate knowledge of the situation of the German troops on the southern front. “I had promised my mother to be unswervingly loyal to the flag of my country. My father had been an officer of the Confederate service, and after the surrender had come North. Her constant admonition to me was to be true under all circumstances, to the flag of my country and be worthy of being called ‘Jed’s boy.’ “The thought of using Muddy in furtherance of my designs had long been planned, but my scheme for using Jack was not conceived until after I found that I could buy him, and had tested his wonderful intelligence for that service. “The enemy was led to believe that others high in the confidence of the American commander were willing to assist in my treason and, among them, Colonel Burbank; and thus I was able to carry out my plan of deception. I never, however, trusted them with the knowledge that Jack was carrying messages without a rider. The colonel’s messages to me were seemingly disloyal, but by previous arrangement of a code, they bore a different meaning to me; and the real information received by the enemy, by his communications, were only those agreed upon by high military Allied officers. “Of late, since all German plans founded on the information I have given them have miscarried, they are suspicious that I have betrayed them. I have been constantly watched--sometimes by men who are in our secret service--but I have been able to elude them by several devices--one of them by exchange of identity with my brother. They have not, with all their acuteness, suspected the horse or dog.
