_October 11._--With the first pencilings of the morning light we took up our line of march toward the Rappahannock. Skirmishing continued nearly every step of the way. On the Sperryville pike to Culpepper we were closely pursued and heavily pressed. At Culpepper the corps separated. Gregg, who had come by way of Cedar Mountain, passed out on the road to Sulphur Springs. Buford moved in the direction of Stevensburg, leaving Kilpatrick alone on the main thoroughfare along the railroad line. Kilpatrick, accompanied by Pleasonton, had scarcely left Culpepper, when Hampton's Legions made a furious attack upon his rearguard, with the hope of breaking through upon the main column to scatter it, or of so retarding its progress that a flanking column might fall upon him ere he could reach the safe shore of the Rappahannock. Our infantry, which yesterday occupied this ground, had retired, leaving the cavalry to struggle out of the toils of the enemy as best it could. Gallantly repelling every attack of the enemy, our command moved on, without expending much of its time and material, until opposite the residence of Hon. John Minor Botts, where a few regiments suddenly wheeled about, and, facing the pursuing foe, charged upon them with pistols and sabres, giving them a severe check and an unexpected repulse. On arriving at Brandy Station Kilpatrick found himself in a most critical situation, with an accumulation of formidable difficulties on every hand, which threatened his annihilation. Buford, who had been sharply pursued by Fitzhugh Lee's division over the plains of Stevensburg, had retired more rapidly than Kilpatrick, and, unaware of his comrade's danger, had suffered Lee to plant his batteries on the high hills which commanded Kilpatrick's right, while the Rebel troopers, in three heavy lines of battle, held the only route by which Kilpatrick could retreat. Lee's sharpshooters also occupied the woods in the immediate vicinity of Kilpatrick's columns, where they were making themselves a source of damage and great annoyance. To increase the danger of the situation, Stuart, by hard marching, had swung around to Kilpatrick's left, and had taken possession of a range of hills, planted batteries, and was preparing to charge down upon the surrounded division below.
