Testimony of Gen. Henry J. Hunt:-- "A storm arose soon after. Just before sunset, the general and his staff re-crossed the river to the north side. I separated from him in order to see to the destruction of some works of the enemy on the south side of the river, which perfectly commanded our bridges. Whilst I was looking after them, in the darkness, to see that they had been destroyed as directed, an engineer officer reported to me that our bridges had been carried away, or were being carried away, by the flood. I found the chief engineer, Capt. Comstock; and we proceeded together to examine the bridges, and we found that they were all utterly impassable. I then proceeded to Gen. Meade's camp, and reported the condition of affairs to him. All communication with Gen. Hooker being cut off, Gen. Meade called the corps commanders together; and, as the result of that conference, I believe, by order of Gen. Couch at any rate, I was directed to stop the movement of the artillery, which was withdrawn from the lines, and let them resume their positions, thus suspending the crossing. On my return to the bridges, I found that one had been re-established, and the batteries that were down there had commenced re-crossing the river. I then sought Gen. Hooker up, on the north side of the river, and proposed to him to postpone the movement for one day, as it was certain we could not all cross over in a night. I stated to him that I doubted whether we could more than get the artillery, which was ordered to cross first, over before daylight: he refused to postpone the movement, and it proceeded. No opposition was made by the enemy, nor was the movement disturbed, except by the attempt to place batteries on the points from which our bridges could be reached, and to command which I had already posted the necessary batteries on my own responsibility. A cannonade ensued, and they were driven off with loss, and one of their caissons exploded: we lost three or four men killed, and a few horses, in this affair. That is about all that I remember." Gen. Barnes's brigade assisted in taking up the bridges; and all were safely withdrawn by four P.M. on Wednesday, under superintendence of Major Spaulding of the engineer brigade.
