29th.—A little occurrence of a very unpleasant nature, today. I have, for a long time, felt that my Colonel was interfering with the Medical Department of the Regiment, to an extent not warranted by the rules of war, and greatly to the prejudice of the health of the men. Seeing so many sick around me, I became excited, and said to him that his interference must stop; that I would submit to it no longer. He considered this insubordination, or something worse, and used language which I construed into a threat of Court-Martial. This was not very soothing to my excitement, or my excitability, and I wrote him a defiant note, inviting him to put his threat in execution. I know it is an offence against military law to use either insulting or disrespectful language to superior officers; and I felt that it was against the law of self-respect to submit to be forever trampled on, so as one of these laws had to be violated, I took my choice. Perhaps I did wrong. The result will show.
