On the ridge west of the Shenandoah, two Rebel batteries were in position, with jets of white smoke bursting from the cannon in quick discharges. There was a small body of Rebels east of the river. Colonel Sargent, commanding the First Massachusetts cavalry, was ordered to drive them across the river. His troops deployed in the open field. At the word of command, they dashed down the hill, supported by a detachment of General Sykes's infantry. The Rebel cavalry did not wait their charge, but fled across the Shenandoah. "Advance skirmishers!" was the order of Colonel Sargent. He had no intention of moving his whole detachment to the river bank, but only his skirmishers. The cavalry and infantry misunderstood the order. Their blood was up. Away they went with a hurrah down to the river-bank. The houses on the other side were full of Rebel infantry. Two cannon commanded the ford, and swept it with canister. "Down! down!" shouted Colonel Sargent. He meant that the soldiers should fall upon the ground, and not expose themselves to the terrible fire which was coming upon them. They thought that he would have them rush down the steep bank and cross the stream, and with wilder enthusiasm--that which sometimes comes to men when in the greatest danger--they went down to the water's edge; some of them into the stream. There they saw their mistake, but they faced the storm a while, and gave volley for volley, although ordered back by their commander. Six or eight were killed, and thirty wounded, during the few moments they were there. Among the killed was the brave Captain Pratt, of the cavalry, shot through the heart. His pulse had just ceased its beating as I stood over him. The blood, still warm, was flowing from the wound. His countenance was calm and peaceful. He had died while doing his duty,--a duty he loved to perform, for he felt that he could not do too much for his country:-- "Wrap round him the banner, It cost him his breath, He loved it in life, Let it shroud him in death. Let it silently sweep in its gorgeous fold O'er the heart asleep, and the lips that are cold." Having secured Snicker's Gap, Pleasanton pushed on to Piedmont and Markham, pleasant places on the Manassas Gap Railroad. Markham is nestled easily at the foot of the mountain, where the railroad begins its long, steep gradient to reach the summit of the gap. At this place, Stuart planted his guns, and a spirited engagement took place.
