It had also been determined that a section of the army should be left behind, under the command of General Irvin McDowell, to guard the approaches to Washington. The First Pennsylvania Cavalry, under the command of General (then Colonel) George Dashiel Bayard, and the Harris Light, remained with the latter force. Under such a leader as Bayard, the men could have no fear of rusting in inactivity. He was the soul of honor, the bravest of the brave. No more gallant spirit ever took up the sword, no kinder heart ever tempered valor, no life was more stainless, no death could be more sad; for the day that was appointed for his nuptials closed over his grave. Judson Kilpatrick, one of those restless, nervous, energetic and self-reliant spirits who believe in themselves thoroughly, and make up in activity what they lack in method, was Colonel of the Harris Light, and the dawning glory of young Bayard's fame excited a spirit of emulation, if not of envy in his heart, which found vent in a very creditable desire to equal or excel that leader in the field. The brilliant night attack on Falmouth Heights was one of the first results of this rivalry, and as it was also the initial battle in Corporal Glazier's experience, we give his own vivid description of it as it is found in "Three Years in the Federal Cavalry." "Our instructions," he says, "were conveyed to us in a whisper. A beautiful moonlight fell upon the scene, which was as still as death; and with proud determination the two young cavalry chieftains moved forward to the night's fray. Bayard was to attack on the main road in front, but not until Kilpatrick had commenced operations on their right flank, by a detour through a narrow and neglected wood-path. As the Heights were considered well-nigh impregnable, it was necessary to resort to some stratagem, for which Kilpatrick showed a becoming aptness. "Having approached to within hearing distance of the rebel pickets, but before we were challenged, Kilpatrick shouted with his clear voice, which sounded like a trumpet on the still night air: "'Bring up your artillery in the centre, and infantry on the left!' "'Well, but, Colonel,' said an honest though rather obtuse Captain, 'we haven't got any inf--' "'Silence in the ranks!' commanded the leader. 'Artillery in the centre, infantry on the left!' "The pickets caught and spread the alarm and thus greatly facilitated our hazardous enterprise. "'Charge!' was the order which then thrilled the ranks, and echoed through the dark, dismal woods; and the column swept up the rugged heights in the midst of blazing cannon and rattling musketry.
