The JUDGE-ADVOCATE. If I have gone outside the examination-in-chief in this examination I shall make no objections to General Buell's additional questions, but I should like General Buell to state what those points were.

General BUELL: The departure from the limits embraced in the examination-in-chief is as to the time occupied by the army in the march from Nashville to Munfordville, and the witness may be able to give some information which you have not exactly upon your record in reference to that.

The JUDGE-ADVOCATE. I cannot admit that I went outside of my examination in that. The witness stated positively that the army stopped for lack of supplies between Munfordville and Nashville.

General buell. There was no attempt made in the examination-in-chief to explain a delay of four or five days at Bowling Green and a delay of four or five days between Bowling Green and Munfordville, a period of about ten days, which the judge-advocate has endeavored to explain by his cross-examination. I wish only to question the witness in reference to the dates of the arrival and departure of the army at several places.

The JUDGE-ADVOCATE. That we have already before us in the evidence of other witnesses. The only object in the cross-examination of Colonel Darr was to test the accuracy of his knowledge in reference to the facts he has given the Commission. As to the dates and the delays and the number of days on the march, that is already before the Commission, and I doubt if Colonel Darr could add anything new upon the subject.

General BUELL. If the Commission desire any further information upon the is subject they may perhaps adopt my questions. I have no desire to put them myself.

The court was hen cleared; when, upon motion whether the rule relating to the re-examination of witness should be suspended, it was decided in the negative.

By General DANA:

Question. How many days' halt of the Army of the Ohio was there between Nashville and Munfordville altogether?

I do not remember exactly. We arrived at Bowling Green the same day on which Munfordville was attacked by the rebels. As fast as the flour came in the troops were supplies and commenced moving. I think I was four came in the troops were supplied and commenced moving. I think I was four or five days in Bowling Green while the troops were marching, but I think we halted two days at Prewitt's Knob; not exactly halted, but the headquarters halted. I can tell about the time that was consumed in marching from Nashville to Munfordville. We arrived at Bowling Green on the 14th, and I think that day week we arrived at Munfordville.

The witness was then dismissed.

General BUELL. I made application for all the signal officers. There seems to have been some difficulty about procuring their attendance. The judge-advocate expressed himself as satisfied that no message was received at headquarters during the day of the Perryville battle. I made this application upon the statement of Colonel McCook, who said in his testimony that he was under the impression that a message had been sent through the signal station giving information of the attack upon General McCook's corps, and also upon a statement in a published letter of Colonel McCook which I saw subsequently. The judge-advocate has said to me, and I suppose has said to the Commission also, that he was satisfied that no such message had been transmitted to headquarters, and that it does not desire further evidence upon that point. I understand that one of the members of the Commission is not satisfied.
