Colonel FORD stated that the following-named witnesses, in addition to those summoned yesterday, were important for him in the inquiry now in progress before this Commission. Wherefore it was ordered that a summons should issue for them.

The following are the names of the witnesses: Captain Brown, Company H, First Regiment Potomac Home Brigade, Annapolis; Mrs. Brown, his wife.

Colonel WILLIAM P. MAULSBY was then duly sworn, who testified as follows to questions propounded by the judge-advocate:

Question. State what position you held in the military service at and immediately preceding the recent evacuation of Maryland Heights by the United States forces.

Answer. I was the colonel commanding First Maryland Regiment Potomac Home Brigade.

Question. State at what point your command was stationed during the period and events referred to, and what part of took therein.

The remainder of my command I stationed on the outer heights, being the same ridge occupied by General Banks' army last summer. I threw out a line of skirmishers, covering the base of that height. I occupied that position the better part of two days and one night. I think the afternoon of the second day Colonel Miles rode up and remarked that that position was not tenable, and ordered me to fall back to the eastern slope of Maryland Heights. I did so, and while in the latter position another piece of artillery was furnished me. White thus situated, I discovered a large wagon-train of the enemy at a distance of about 3 miles, in Pleasant Valley, which, I suppose, was visible in its length from 1 to 2 miles, neither
