Miss Todd (afterwards Mrs. Lincoln) had a keen sense of the ridiculous, and wrote several articles in the Springfield (Ill.) "Journal" reflecting severely upon General James Shields (who won fame in the Mexican and Civil Wars, and was United States Senator from three states), then Auditor of State.
Lincoln assumed the authorship, and was challenged by Shields to meet him on the "field of honor." Meanwhile Miss Todd increased Shields' ire by writing another letter to the paper, in which she said: "I hear the way of these fire-eaters is to give the challenged party the choice of weapons, which being the case, I'll tell you in confidence that I never fight with anything but broom-sticks, or hot water, or a shovelful of coals, the former of which, being somewhat like a shillalah, may not be objectionable to him."
Lincoln accepted the challenge, and selected broadswords as the weapons. Judge Herndon (Lincoln's law partner) gives the closing of this affair as follows:
"The laws of Illinois prohibited dueling, and Lincoln demanded that the meeting should be outside the state. Shields undoubtedly knew that Lincoln was opposed to fighting a duel--that his moral sense would revolt at the thought, and that he would not be likely to break the law by fighting in the state. Possibly he thought Lincoln would make a humble apology. Shields was brave, but foolish, and would not listen to overtures for explanation. It was arranged that the meeting should be in Missouri, opposite Alton. They proceeded to the place selected, but friends interfered, and there was no duel. There is little doubt that the man who had swung a beetle and driven iron wedges into gnarled hickory logs could have cleft the skull of his antagonist, but he had no such intention. He repeatedly said to the friends of Shields that in writing the first article he had no thought of anything personal. The Auditor's vanity had been sorely wounded by the second letter, in regard to which Lincoln could not make any explanation except that he had had no hand in writing it. The affair set all Springfield to laughing at Shields."
