Lander was then at Pawpaw Tunnels, on the Maryland shore of the Potomac, a station on the Baltimore and Ohio railroad, midway between Hancock and Cumberland, with a small force. He immediately marched to New Creek, in Hampshire county, Va., to join the detachment of troops at that point, where he also hastily concentrated all his available command. Taking twenty wagons loaded with lumber, he proceeded to a point on the Cacapon river, seven miles south of the railroad, and between the hours of nine and one o’clock at night he improvised a bridge one hundred and eighty feet long, by placing the wagons in the river as a foundation, over which he marched his force of four thousand men, and advanced upon the enemy’s pickets before the dawn of day. With five hundred of the First Virginia cavalry, under Colonel Anastanzel, he had designed to charge through the rebel camp at the Gap, and then form immediately in his rear, cut off the retreat, and capture the whole force, after the Federal infantry, following up the cavalry charge, should have completed the discomfiture of the enemy. But the rebels had retired before Lander’s approach; and when led by the General and his staff, the cavalry flew through the Gap and beyond it, they met with no opposition. Colonel Anastanzel was at once ordered to push forward on the Winchester road with the cavalry, reconnoitre, and, if possible, overtake and capture the baggage of the enemy. General Lander meantime brought up Colonel Carroll with the Eighth Ohio regiment, and the Seventh Virginia, Colonel Evans, for a support. Colonel Anastanzel encountered the enemy at the head of the pass, two miles from Blooming. He was met by a sharp fire, and halted his command. On hearing the firing, General Lander came up and led the charge, followed by Major Armstrong, Assistant Adjutant-General; Lieutenants Fitz-James O’Brien, the well-known poet of his staff, and Major Bannister, Paymaster U.S.A., who had volunteered for the expedition. A group of rebel officers were distant about three hundred yards, encouraging their men. General Lander being the best mounted, outran the rest of the party, and cut off the retreat of the rebel officers. “Surrender, gentlemen,” he said, coolly dismounting, and extending his hand to receive the sword of Colonel Baldwin, over whom an instant before he had appeared to be riding. Five of the rebel officers surrendered to General Lander, and four others immediately afterward, to the officers of his staff, among them the Assistant Adjutant-General of General Carson.
