the captain. The cell is not a comfortable place; it is dry but cold. I suffered from the cold and was fed on bread and water. I think I was kept there five days. I thought the letter would go quicker and surer by sending through private hands. I am seventeen years old. I don't know what I am detained for.

JOHN DOYLE sworn:

I have been in the Castle now four weeks. I don't know Captain Alexander; would not know him if I was to see him. I am treated as well as the others, I reckon. I never was punished; in fact I don't deserve it. I was shot at once in the window, or at least I thought I was shot at; but I don't believe he intended to hit me, for I don't deserve it.

By Mr. WARD:

Question. Didn't a shot go through you hat?

Answer. Can't tell; there is a hole through it.

JAMES McALISTER sworn:

I am a seaman and came from Wilmington, N. C. I came here when the war broke out. I have not been treated by Captain Alexander as a man should be treated. I have been tied up and flogged like a negro.

By Mr. WARD:

Question. How many lashes did you receive?

Answer. Twelve I think, and by Captain Alexander's order they were laid on as hard as I could well have stood it.

Question. Was the blood cut out of you?

Answer. No; but I was black and blue and was sore for a month afterwards. I was shipped with a strap three inches wide and the blows were laid on by Caphart. I have been bucked for four hours in front of the office entrance where everybody could see me. bucking is not painful but it mortifies and makes one ashamed.

Question. Do you know of any other punishments?

Answer. Yes; I was shot at once for standing at a window and looking out. The ball passed my head and went up through the hospital which was full of patients.

Mr. Wynne, doorkeeper of the House of Representatives, detailed before the committee some circumstances of his treatment at the prison when he went down to summon some officers and the purport of his conversation with several witnesses, which not being to the point here is omitted.

MONDAY, April 27, 1863.

Honorable Judge OULD sworn.

By Captain ALEXANDER:

Question. You, as judge-advocate of the court-martial, can give the committee some idea of the character of the prisoners?

Answer. The most of the cases brought before me were cases of desertion, coupled with theft and cases of insubordination.

Question. Do you think I am a cruel man?

Answer. I do not know about that. I do not think you are.

Question. What do you think about me carrying out an order?

Answer. Being a military man you would see any reasonable order carried out. I have conversed at times with persons who have been in Castle Thunder and have questioned them as to their treatment there. Never heard them mention any cases of cruelty but generally the reverse. There has been half a dozen sentenced to be shot and two condemned to be hung. We have never resorted to the death penalty unless the case presented the two aggravated phases - first, desertion, and secondly, desertion in face of the enemy. I know nothing of the punishments by the commandant of the Castle; never visited it in my life that I know of. In all sentences of court-martial the lashes were laid on except in one instance.
