The writer, through a copy of the April 21st issue of the Journal sent to Dr. Samuel? Mudd by one of his friends in Baltimore, was enabled to read and appreciate the Honorable J. S. Black's arguments before the Supreme Court in regard to Milligan and others. He Points out that McMaster had remarked that the decision of the Supreme Court must carry with it the release on Habeas Corpus of Dr. Mudd, Colonel Marmaduke and other prisoners at the Dry Tortugas and other civilians sentenced by Military Commissions. By Colonel Marmaduke the writer supposes McMaster to mean Colonel Grenfell, as Marmaduke was acquited by the Military Commission, as were Judge Morris, Cantrill, Walsh and Semmes. Only the Writer, by especial favor, was sentenced to be hung, which sentence was graciously commuted by the Chief Magistrate of this Republic to life imprisonment at hard labor on this desert island. Crenfell says he was introduced to McMaster at the trial in the Cincinnati Court House and was impressed with McMaster's manly and fearless testimony before that packed and projudiced Commission. It won his respect, and he feels that he can appeal to McMaster to aid him to legally escape from this den of misery and death. He charges no one with wilfully allowing him to be convicted, but feels that perhaps he did not pick the right lawyer, which fact he did not discover until he was already doomed. He hopes that his present legal advisor, Mr. Robert Hervey of Chicago, is sincere when he says he will leave no stone unturned to obtain the writers release, but he feels that the man is far from having the talent, courage, and influence of McMaster. He begs McMaster's assistance and mentions that though he has powerful friends in England, they cannot help him. He mentions several English connections, and thanks McMaster for any help he will advance. :: I-1-n A.L.S. 3pp. 8vo.
