This murderous fire was repeated over and over again. There was no waiting to swab the guns, but, fast as powder and ball could be served, the ordnance sent out its volleys. The enemy made a desperate stand, but every shot swept down the men in masses. A vacant space appeared for a moment, then fresh men filed in. Twice they attempted to reform and charge the battery, but the rapidity with which the pieces were served, and the peculiar nature of the ground, rendered every shot effective, and they were swept back, cut down, speedily disorganized, and fled for the woods. During all this action, Lieutenant-Colonel Marsh, of the Sixteenth, and Colonel Pratt, of the Thirty-first (the former since killed, and the latter wounded before Richmond), controlled their men perfectly. Not an infantry shot was fired during the engagement. Balls from the enemy struck the ground in volleys before the men, filling their eyes with dust. No man gave way; they were compelled to change position three times during the fight. Although so many of the enemy were killed, this spot being named, in the secession reports, as giving the heaviest mortality of the day, only two men of Davies’ command were hurt. One man was wounded, and Lieutenant Craig, a brave young officer from West Point, was killed. This brilliant engagement, so important in its results, sprang out of a singular series of accidents: first, in the mistake made in reading Richardson’s dispatch, and again in a failure of orders. When the main army began its retreat past Centreville, at four o’clock, Colonel Miles sent his aid, Captain Vincent, to order Davies and his command back to Centreville, but Vincent, instead of coming first to Davies, stopped to give orders to Richardson, and two regiments of Davies’ brigade, stationed to guard his rear. After ordering Richardson back, Vincent came over the ravine to deliver his orders to Davies, when he heard his firing on the extreme left, went back to Centreville, to report, and returned just as the firing ceased, to direct Colonel Davies to retire on Centreville. Davies, ignorant that Richardson had already fallen back, rode over to order his retreat, but to his astonishment, almost horror, found that the whole brigade, with two regiments of his own forces left to guard his rear, had been gone a full hour. Thus it happened that this important engagement had been fought and won with a single battery and two regiments of infantry, utterly alone and unsupported on the deserted battle-field, against a large body of men, endeavoring to sweep to the rear and cut off the army in its retreat.
