John E. Cook was a native of Connecticut and he was a young man of about twenty-eight years--five feet and eight inches in height, though, as he stooped a good deal, he did not appear to be so tall. He had fair hair and bright blue eyes and he was, on the whole, quite an intelligent looking man. As before stated, he had resided several years at Harper's Ferry, and he had become acquainted with all the young men of the place, by whom he was regarded as a pleasant companion. He had married a respectable young lady of the place, who knew nothing of his former life or of his plans against the peace of Virginia. He was highly connected and the governor of Indiana at that time--Willard--was his brother-in-law, being the husband of Cook's sister. At his trial Daniel Voorhees, afterward so famous as a politician and criminal lawyer, made a speech for the defense which is regarded as one of his best efforts. Little is known of Stuart Taylor. Some contend that he was a man of medium size and very dark complexion, while others believe that he was a redhaired young man who was bayoneted by the marines in the engine house and dragged dead from that building at the same time that Brown was removed. The writer is inclined to the latter opinion and he thinks that those who favor the former confound him with a man named Anderson of whom mention will soon be made at some length. William Lehman, who was killed on a rock in the Potomac while endeavoring to escape, was quite a young man, with jet black hair and a very florid complexion. The killing of this young man was, under all circumstances of the case, an act of great barbarity, as he had made signs of a desire to surrender. The man who shot him was, as before stated, but a temporary resident of Harper's Ferry and, in reality, belonged to a neighboring county. Nothing can be gained by giving his name and the concealing of it may save people yet unborn from unmerited shame. In justice it must be said that he now claims that Lehman drew a pistol to shoot him, but we did not hear of this until very lately. William Thompson, who was shot on the bridge, was a man apparently of about thirty years of age, of medium size, but of a symmetrical and compact form. His complexion was fair, and he gave indications of being a man of pleasant disposition. He was well known to many in the neighborhood of the Kennedy farm and he was very popular with all his acquaintances there. The killing of this man was unnecessary, also, but some palliation for it may be found in the excitement caused by Mr. Beckham's death.
