The remnant of the Guard are now in the field under the hill, and from the shape of the ground the Rebel fire sweeps with the roar of a whirlwind over their heads. Here we will leave them for a moment, and trace the fortunes of the Prairie Scouts. When Foley brought his troop to a halt, Captain Fairbanks, at the head of the first company of Scouts, was at the point where the first volley of musketry had been received. The narrow lane was crowded by a dense mass of struggling horses, and filled with the tumult of battle. Captain Fairbanks says, and he is corroborated by several of his men who were near, that at this moment an officer of the Guard rode up to him and said, "They are flying; take your men down that lane and cut off their retreat,"--pointing to the lane at the left. Captain Fairbanks was not able to identify the person who gave this order. It certainly did not come from Zagonyi, who was several hundred yards farther on. Captain Fairbanks executed the order, followed by the second company of Prairie Scouts, under Captain Kehoe. When this movement was made, Captain Naughton, with the Third Irish Dragoons, had not reached the corner of the lane. He came up at a gallop, and was about to follow Fairbanks, when he saw a Guardsman who pointed in the direction in which Zagonyi had gone. He took this for an order, and obeyed it. When he reached the gap in the fence, made by Foley, not seeing anything of the Guard, he supposed they had passed through at that place, and gallantly attempted to follow. Thirteen men fell in a few minutes. He was shot in the arm and dismounted. Lieutenant Connolly spurred into the underbrush and received two balls through the lungs and one in the left shoulder. The Dragoons, at the outset not more than fifty strong, were broken, and, dispirited by the loss of their officers, retired. A sergeant rallied a few and brought them up to the gap again, and they were again driven back. Five of the boldest passed down the hill, joined Zagonyi, and were conspicuous by their valor during the rest of the day.--Fairbanks and Kehoe, having gained the rear and left of the enemy's position, made two or three assaults upon detached parties of the foe, but did not join in the main attack.
