Springfield, Oct. 3, 1842. To the Editor op "The Sangamon Journal." Sir,--To prevent misrepresentation of the recent affair between Messrs. Shields and Lincoln, I think it proper to give a brief narrative of the facts of the case, as they came within my knowledge; for the truth of which I hold myself responsible, and request you to give the same publication. An offensive article in relation to Mr. Shields appeared in "The Sangamon Journal" of the 2d September last; and, on demanding the author, Mr. Lincoln was given up by the editor. Mr. Shields, previous to this demand, made arrangements to go to Quincy on public business; and before his return Mr. Lincoln had left for Tremont, to attend the court, with the intention, as we learned, of remaining on the circuit several weeks. Mr. Shields, on his return, requested me to accompany him to Tremont; and, on arriving there, we found that Dr. Merryman and Mr. Butler had passed us in the night, and got there before us. We arrived in Tremont on the 17th ult.; and Mr. Shields addressed a note to Mr. Lincoln immediately, informing him that he was given up as the author of some articles that appeared in "The Sangamon Journal" (one more over the signature having made its appearance at this time), and requesting him to _retract_ the offensive allusions contained in said articles in relation to his private character. Mr. Shields handed this note to me to deliver to Mr. Lincoln, and directed me, at the same time, not to enter into any verbal communication, or be the bearer of any verbal explanation, as such were always liable to misapprehension. This note was delivered by me to Mr. Lincoln, stating, at the same time, that I would call at his convenience for an answer. Mr. Lincoln, in the evening of the same day, handed me a letter addressed to Mr. Shields. In this he gave or offered no explanation, but stated therein that he could not submit to answer further, on the ground that Shields's note contained an assumption of facts and also a menace. Mr. Shields then addressed him another note, in which he disavowed all intention to menace, and requested to know whether he (Mr. Lincoln) was the author of either of the articles which appeared in "The Journal," headed "Lost Townships," and signed "Rebecca;" and, if so, he repeated his request of a retraction of the offensive matter in relation to his private character; if not, his denial would be held sufficient. This letter was returned to Mr. Shields unanswered, with a verbal statement "that there could be no further negotiation between them until the first note was withdrawn." Mr. Shields thereupon sent a note designating me as his friend, to which Mr. Lincoln replied by designating Dr. Merryman. These three last notes passed on Monday morning, the 19th. Dr. Merryman handed me Mr. Lincoln's last note when by ourselves. I remarked to Dr. Merryman that the matter was now submitted to us, and that I would propose that he and myself
