But keep well behind the hedge that you see ahead." Marlowe was his second in command, and taking the lead he continued with the troop.
Marlowe rode behind one of the hedges, where they were hidden from the lone horseman on the hill, and Sherburne and Harry and the eight men followed.

While they were yet hidden, Sherburne and his chosen band suddenly detached themselves from the others at a break in the hedge and galloped toward the horseman who was still standing on the hill, gazing intently toward the point where he had last seen the troop riding.
Sherburne, Harry and the privates rode at a gallop across the field, straight for the Union sentinel.

He did not see them until they had covered nearly half the distance, and then with aggravating slowness he turned and rode over the opposite side of the hill.

Harry had been watching him intently, and when he had come much nearer the figure seemed familiar to him.

At first he could not recall it to mind, but a moment or two later he turned excitedly to Sherburne.
"I know that man, although I've never seen him before in a uniform," he said.
