Buckland Mills was, in some sort, a sequel to Brandy Station. The latter battle was a brilliant passage at arms, in which neither side obtained a decisive advantage. Kilpatrick was still pugnacious and both willing and anxious to meet Stuart again. That his mind was full of the subject was evinced by a remark he was heard to make one morning at his headquarters on the Bull Run battle ground. He was quartered in a house, his host a Virginian too old to be in the army, and who remained at home to look after the property. It was a clear day, and when the general came out on the porch, the old gentleman accosted him with a cheery:
"Yes, a--fine day for a fight;" was the instant reply.
In most men this would have sounded like gasconade. In Kilpatrick's case, it was not so considered. He was credited with plenty of pluck, and it was well understood that he was no sooner out of one action, than he was planning to get into another. He ran into one, a day or two later, which furnished him all the entertainment of that kind that he wanted, and more too.
Reconnoissances across Bull Run on the Gainesville road disclosed a considerable force of mounted confederates. When their pickets were driven in by the Sixth Michigan on the 15th and again by the First Michigan on the 16th strong reserves were revealed. As a matter of fact, Stuart was at Buckland Mills with Hampton's division, and Fitzhugh Lee was at or near Auburn, but a few miles away. They had their heads together and devised a trap for Kilpatrick, into which he rode with his eyes shut.
Sunday evening, October 18, the Third division moved out across Bull Run, Kilpatrick in command, Custer's brigade leading, Davies[16] with the First brigade bringing up the rear. Stuart's cavalry was attacked and driven rapidly until dark by the First Vermont cavalry[17] under Lieutenant Colonel Addison W. Preston, acting as advance guard. Early on Monday morning, October 19, the march was resumed, the Sixth Michigan in advance.
About midway between Bull Run and Broad Run the confederate rear guard, a regiment of Young's brigade of Hampton's division, was encountered which fell back before the advance of the Sixth Michigan making but slight resistance and retreating across Broad Run, where it was found that Stuart had taken up a strong position, forming the three brigades of Gordon, Rosser and Young in line on the opposite side, as if to contest the crossing.
