With yells distinctly heard above the roar they advanced. The batteries on each side redoubled their discharges. From our irregular line of infantry extending more than a mile blazed incessant sheets and spurts of flame, the smoke at times hiding the combatants. Gordon was heading toward the now nearly empty ravine. My horse had just been shot under me. I lost two in that fight. Dismounted I walked from the right of my battalion to the left, cautioning my men against wasting their ammunition, bidding them take sure aim, pick out the rebel officers, and not fire too high. They were shooting from a recumbent position, or resting on one knee; lying flat on their backs to reload. As I reached the left, I glanced to the right and saw several of them starting to their feet, and a little further on, two or three began to run back. I rushed to the spot shouting, "Back to your places!" I saw the cause: the regiments on our right were retreating. I was astounded, for we were expecting an order to advance instantly. At that moment Lieutenant Handy, an aide of our brigade commander, rode up, pale, excited, his hands flung up as if in despair. My men were springing to their feet. "What are those orders?" I demanded. "Retreat, retreat! get to the rear as fast as possible," he replied. "Battalion, rise up; shoulder arms--" I commanded. Before I could finish the order, one of Sheridan's staff came on a swift gallop, his horse white with foam. "For God's sake, what does this mean?" said he; "this retreat must be stopped!" "Battalion, lie down," I shouted; "our brigade commander ordered retreat!" "It's all wrong. If this position's lost, all's lost. Here you have some cover. Hold it to the last. I'll bring supports immediately." Striking spurs into his steed, he vanished in the direction of the retreating regiments. Except the few who had heard my command and remained in position, perhaps seventy-five or a hundred, who kept blazing away at the Confederates, rising a little to kneel and fire, Grover's Division, and all we could see of that of Ricketts, had gone to pieces, swept away like chaff before a whirlwind. Not a Union flag now in sight, but plenty of the "Stars and Bars!" Our sputtering fire checked some directly in front; but most of the on-rushing masses were deflected by the nature of the ground. Out of our view and about half a mile in our rear was Dwight's Division, the First of the Nineteenth Corps. It had been left in reserve. It was in line of battle and ready for the onset. The confused fragments of Grover were rallied behind it. Had the ground been favorable, and had no unexpected opposition been encountered, Gordon would have crushed Dwight.
