I sought him out, and received his orders to join in pursuit of the enemy, who was falling back to the left of the road by which the army had approached from Sudley Springs.

Placing Colonel Quinby's regiment of rifles in front, in column, by division, I directed the other regiments to follow in line of battle, in the order of the Wisconsin Second, New York Seventy-ninth, and New York Sixty-ninth.
Quinby's regiment advanced steadily down the hill and up the ridge, from which he opened fire upon the enemy, who had made another stand on ground very favorable to him, and the regiment continued advancing as the enemy gave way, till the head of the column reached the point near which Rickett's battery was so severely cut up.

The other regiments descended the hill in line of battle, under a severe cannonade; and, the ground affording comparative shelter from the enemy's artillery, they changed direction, by the right flank, and followed the road before mentioned.

At the point where this road crosses the ridge to our left front, the ground was swept by a most severe fire of artillery, rifles, and musketry, and we saw, in succession, several regiments driven from it; among them the Zouaves and battalion of marines.

Before reaching the crest of this hill, the roadway was worn deep enough to afford shelter, and I kept the several regiments in it as long as possible; but when the Wisconsin Second was abreast of the enemy, by order of Major Wadsworth, of General McDowell's staff, I ordered it to leave the roadway, by the left flank, and to attack the enemy.
This regiment ascended to the brow of the hill steadily, received the severe fire of the enemy, returned it with spirit, and advanced, delivering its fire.
