Another remarkable case in which he was engaged, was, the defence of young Armstrong from a charge of murder. This Armstrong was the son of a man who had befriended and employed Mr. Lincoln in youth, and the present charge was, that he had killed a certain person who had unquestionably died from injuries received in a camp-meeting riot where young Armstrong was present. The father was dead, and the mother aged and poor; a chain of apparently perfectly conclusive circumstantial evidence had been forged, which had convinced the community of Armstrong's guilt; indeed, had he not been safely secured in a strong jail he would have been lynched. Neither the youth nor his old mother had any money. The people and the newspapers were furious against the prisoner; and his fate appeared absolutely certain even to himself, when Mr. Lincoln, hearing of the matter in some way, volunteered for the defence, and was gladly accepted. When the trial came on, the evidence for the prosecution was given, and constituted what appeared to the audience a perfectly conclusive proof of guilt. Lincoln cross-examined very lightly, only correcting up and ascertaining a few places and dates; and his own witnesses were only to show comparatively good previous character for the prisoner. The prosecutor, sure of his prey, made only a short and formal argument. Mr. Lincoln followed for the defence. He began slowly, calmly, carefully. He took hold of the heart of the evidence for the state--that of the chief witness. He pointed out first one discrepancy, and then another, and then another. He came at last to that part of the evidence where this principal witness had sworn positively that he had been enabled by the light of the moon to see the prisoner give the fatal blow with a slung shot; and taking up the almanac he showed that at the hour sworn to on the night sworn to _the moon had not risen_; that the whole of this evidence was a perjury.
