From New Market we sent the regiment of cavalry off to the right to cover our flank, and to investigate reports that heavy bodies of the enemy's cavalry were north of us. The infantry pushed rapidly toward Frederick. The opposition was very slight till we reached the Monocacy River, which is perhaps half a mile from the town. Here General Wade Hampton, with his brigade as rear-guard of Lee's army, attempted to resist the crossing. The highway crosses the river by a substantial stone bridge, and the ground upon our bank was considerably higher than that on the other side. We engaged the artillery of the enemy with a battery of our own, which had the advantage of position, whilst the infantry forced the crossing both by the bridge and by a ford a quarter of a mile to the right. As soon as Moor's brigade was over, it was deployed on the right and left of the turnpike, which was bordered on either side by a high and strong post-and-rail fence. Scammon's was soon over, and similarly deployed as a second line, with the Eleventh Ohio in column in the road. Moor had with him a troop of horse and a single cannon, and went forward with the first line, allowing it to keep abreast of him on right and left. I also rode on the turnpike between the two lines, and only a few rods behind Moor, having with me my staff and a few orderlies. Reno was upon the other bank of the river, overlooking the movement, which made a fine military display as the lines advanced at quick-step toward the city. Hampton's horsemen had passed out of our sight, for the straight causeway turned sharply to the left just as it entered the town, and we could not see beyond the turn. We were perhaps a quarter of a mile from the city, when a young staff officer from corps headquarters rode up beside me and exclaimed in a boisterous way, "Why don't they go in faster? There's nothing there!" I said to the young man, "Did General Reno send you with any order to me?" "No," he replied. "Then," said I, "when I want your advice I will ask it." He moved off abashed, and I did not notice what had become of him, but, in fact, he rode up to Colonel Moor, and repeated a similar speech. Moor was stung by the impertinence which he assumed to be a criticism upon him from corps headquarters, and, to my amazement, I saw him suddenly dash ahead at a gallop with his escort and the gun. He soon came to the turn of the road where it loses itself among the houses; there was a quick, sharp rattling of carbines, and Hampton's cavalry was atop of the little party. There was one discharge of the cannon, and some of the brigade staff and escort came back in disorder. I ordered up at "double quick" the Eleventh Ohio, which, as I have said, was in column in the road, and these, with bayonets fixed, dashed into the town. The enemy had not waited for them, but retreated out of the place by the Hagerstown road. Moor had been ridden down, unhorsed, and captured. The artillery-men had
