" The operator refused point blank to turn over the key to Captain Comstock as directed by me, stating that his orders from the War Department were not to give it to anybody—the commanding general or any one else. I told him I would see whether he would or not. He said that if he did he would be punished. I told him if he did not he most certainly would be punished. Finally, seeing that punishment was certain if he refused longer to obey my order, and being somewhat remote (even if he was not protected altogether from the consequences of his disobedience to his orders) from the War Department, he yielded. When I returned from Knoxville I found quite a commotion. The operator had been reprimanded very severely and ordered to be relieved. I informed the Secretary of War, or his assistant secretary in charge of the telegraph, Stager, that the man could not be relieved, for he had only obeyed my orders. It was absolutely necessary for me to have the cipher, and the man would most certainly have been punished if he had not delivered it; that they would have to punish me if they punished anybody, or words to that effect.
