“You A. B. do swear that you will well and truly try and determine, according to evidence, the matter now before you, between the United States of America, and the prisoner to be tried, and that you will duly administer justice, according to the provisions of “An act establishing rules and articles for the government of the armies of the United States,” without partiality, favor or affection; and if any doubt shall arise, not explained by said articles, according to your conscience, the best of your understanding, and the custom of war, in like cases; and you do further swear, that you will not divulge the sentence of the court until it shall be published by the proper authority; neither will you disclose or discover the vote or opinion of any particular member of the court martial, unless required to give evidence thereof as a witness, by a court of justice, in a due course of law. _So help you God._” And as soon as the said oath shall have been administered to the respective members, the president of the court shall administer to the judge advocate, or person officiating as such, an oath in the following words: “You A. B. do swear, that you will not disclose or discover the vote or opinion of any particular member of the court martial, unless required to give evidence thereof as a witness, by a court of justice in due course of law. Nor divulge the sentence of the court to any but the proper authority, until it shall be duly disclosed by the same. _So help you God._” Art. 70. When any prisoner arraigned before a general court martial shall, from obstinate and deliberate design, stand mute or answer foreign to the purpose, the court may proceed to trial and judgment as if the prisoner had regularly pleaded not guilty. Art. 71. When a member shall be challenged by a prisoner, he must state his cause of challenge, of which the court shall, after due deliberation determine the relevancy or validity, and decide accordingly; and no challenge to more than one member at a time shall be received by the court. Art. 72. All the members of a court martial are to behave with decency and calmness; and in giving their votes, are to begin with the youngest in commission. Art. 73. All persons who give evidence before a court martial, are to be examined on oath or affirmation in the following form: “You swear or affirm (as the case may be) the evidence you shall give in the cause now in hearing, shall be the truth, the whole truth, and nothing but the truth. _So help you God._” Art. 74. On the trials of cases not capital, before courts martial, the deposition of witnesses not in the line or staff of the army, may be taken before some justice of the peace, and read in evidence; provided, the prosecutor and person accused are present at the taking the same, or are duly notified thereof.
