abouts was still a problem to the enemy. Before reaching Frederick I crossed the Monocacy, and continued the march through the night via Liberty, New Market and Monrovia, on Baltimore and Ohio railroad, where we cut the telegraph wires and obstructed the railroad. We reached at daylight Hyattstown, on McClellan's line of wagon communication with Washington; but we found only a few wagons to capture, and pushed on to Barnsville, which we found just vacated by a company of the enemy's cavalry. We had here corroborated what we had heard before—that Stoneman had between four and five thousand troops about Poolesville, and guarding the river fords. I started directly for Poolesville, but instead of marching upon that point I avoided it by a march through the woods, leaving it two or three miles to my left, and getting into the road from Poolesville to the mouth of the Monocacy. Guarding well my flanks and rear, I pushed boldly forward, meeting the head of the enemy's column going toward Poolesville. I ordered the charge, which was responded to in handsome style by the advance squadron (Irving's) of Lee's brigade, which drove back the enemy's cavalry upon the column of infantry advancing to occupy the crest from which the cavalry were driven. Quick as thought Lee's sharpshooters sprang to the ground, and engaging the infantry skirmishers, held them in check till the artillery in advance came up, which, under the gallant Pelham, drove back the enemy's force upon his batteries beyond the Monocacy, between which and our solitary gun quite a spirited fire continued for some time. This answered, in connection with the high crest occupied by our piece, to screen entirely my real movement quickly to the left, making a bold and rapid strike for White's ford to force my way across before the enemy at Poolesville and Monocacy could be aware of my design.
Although delayed somewhat by about 200 infantry, strongly posted in the cliffs over the ford; yet they yielded to the moral effect of a few shells before engaging our sharpshooters, and the crossing of the canal, now dry, and river was effected with all the precision of passing a defile on drill—a section of artillery being sent with the advance and placed in position on the Loudoun side, another piece on the Maryland height, while Pelham continued to occupy the attention of the enemy with the other, withdrawing from position to position until his piece was ordered to cross. The enemy was marching from Poolesville in the meantime, but came up in line of battle on the Maryland bank only to receive a thun-
