William Walker was charged with inciting mutiny and insubordination as the leader of a group of Black soldiers whose "protest" was the stacking of arms in his Commanding officer's tent and refusal to work or obey orders:
"On the morning of Nov. 19, 1863, when a portion of the command was in a state of mutiny, I noticed the accused, with others of his company and regiment stack his arms, take off his accouterments and hang them on the stack. I inquired what all this meant, and received no reply, and again repeated the question, when the accused answered by saying, that they "would nor do duty any longer for seven dollars per month." I then told the men the consequences of a mutiny, and what they might expect. I told them if they did not take their arms and return to duty, I should report the case to the Post Commander and they would be shot down. While saying this, I heard the accused tell the men not to retake their arms, but leave them and go to their street, which command of his they obeyed. Again, later in the day, in the evening, I ordered the accused in arrest, and told him not to leave his tent without my permission, if he did, I should confine him to the Provost Guard. The next morning, Nov. 20 1863, I received information he had broken his arrest, by leaving his tent and going into another tent & company street. I then ordered him to the Provost Guard House."
Walker was found guilty of the charges and executed before the trial transcripts and sentence were submitted to Lincoln for mandatory review. Lincoln didn't know about it until after Walker had been buried!
