The narrow pass of the Berryville pike was so obstructed by artillery, ambulances, ammunition wagons, etc., that it was nearly eight o'clock before the Sixth Corps, which should have been in position with Wilson's Cavalry at sunrise, began to arrive; and it was fully two hours later when the Nineteenth Corps debouched and deployed. Here was miscalculation or bad management or both. This long delay, which the quick-moving cavalry leader Sheridan had not foreseen nor provided for, gave time for Early to call in the strong divisions of Generals Gordon, Breckenridge, and Rodes, from the vicinity of Stephenson's Depot several miles away. They left Patton's Brigade of Infantry, and a part of Fitzhugh Lee's Cavalry to oppose Torbert. Hearing nothing from Torbert, who had now been gone seven or eight hours on his circuitous route, Sheridan suddenly changed his whole plan of action, a perilous maneuver in the face of an active enemy while the battle is already raging intermittently. Instead of flinging Crook's Army of West Virginia, 17 regiments and 3 batteries, across the Staunton pike, to front northeasterly and cut off all possible retreat of the Confederates, he determined to move it to our right and deploy it in line with the Nineteenth. Doubtless this was best under the circumstances, though it left to the enemy the broad smooth highway as a line of retreat up the valley. Grover's Division (2d of the Nineteenth Corps) in four brigades formed line of battle in front and to the right of the gorge. In touch on the left was Ricketts' Division of the Sixth Corps, and resting on Ricketts' left was Getty's Division of the same corps. Getty had 16 regiments in line; Ricketts, 12 with 6 batteries; Grover, 20 with 3 batteries. Had Sheridan been able to strike Early by half-past eight with the Sixth and Nineteenth, he would have crushed him in detail. Had Early massed the divisions of Gordon, Breckenridge, and Rodes, and hurled them at the mouth of the canyon at ten o'clock while half of the Nineteenth was still entangled in it, he would probably have split our army into three parts, and destroyed those already arrived. It was now eleven o'clock, and the Army of West Virginia at last emerged from the defile. To make room for its movement in our rear behind Grover's Division, and to hold the enemy in play until it should have taken its place on the right of the Nineteenth, and perhaps to await there the appearance of Torbert's Cavalry, it was desirable that Grover should advance. Sheridan of course meant the whole front of the Sixth and Nineteenth to keep in a continuous line. At first it seemed to me that the regiments of the Nineteenth overlapped; but the lines of advance were slightly divergent, and wide breaks began to appear between battalions. Especially on the left of the Nineteenth a large and widening gap appeared; for Ricketts had been instructed to guide on the Berryville pike, and that bore away to the left and south.
