The artillery all along the line burst out in torrents of shells, but Si's eyes were glued on the two little brigades. He saw the white spurts from the skirmishers' rifles, and men drop among the rebels,112 who yet moved slowly forward, like some all-engulfing torrent. The skirmishers ran back to the main line, and along its front sped a burst of smoke as each regiment fired by volley. The foremost rebel line quivered a little, but moved steadily on. Then a cloud of white smoke hid both Union and rebel lines, and from it came the sound as of thousands of carpenters hammering away industriously at nails. Presently Si was agonized to see a fringe of blue break back from the bank of smoke, and run rapidly to the rear. They were followed by regiments falling back slowly, in order, and turning at the word of command to deliver volleys in the faces of their yell ing pursuers. Si looked at his Colonel, and saw him anxiously watching the brigade commander for orders to rush across the river to the assistance of the two brigades. Suddenly there was a whirl in front. A battery galloped up, the drivers lashing the horses, the cannoneers sitting stolidly on the limbers with their arms folded. It swept by to a knoll in front and to the right, which commanded the other side of the river. Instantly the gunners sprang to the ground, the cannon were tossed about as if they were play things, and before Si could fairly wink he saw the guns lined up on the bank, the drivers standing by the horses' heads, and the cannons belching savagely into the flanks of the horde of rebels. Then another battery swept up alongside the first, and another, until 58 guns crowned the high banks and thundered until the earth shook as with the ague. A deluge of iron swept the fields where the mighty113 host of rebels were advancing. Tops were torn out of trees and fell with a crash, fence-rails and limbs of oak went madly flying through the air, regiments and brigades disappeared before the awful blast. For a few minutes Si and Shorty stood appalled at the deafening crash and the shocking destruction. Then they saw the rebels reel and fly before the tornado of death.114 A great shout arose from thousands of excited men standing near. Regiments and brigades started as with one impulse to rush across the river and pursue the flying enemy. The 200th Ind. was one of these. No one heard any orders from the officers. The men caught the contagion of victory and rushed forward, sweeping with them the lately-defeated brigades, hurrying over the wreckage of the cannon-fire, over the thickly-strewn dead and wounded, and gathering in prisoners, flags and cannon. They went on so, nearly to the breastworks behind which the rebels were seeking shelter. Si and Shorty were among the foremost. A few hundred yards from the rebel works Si fell to the ground without a groan. Shorty saw him, and ran to him. The side of his head was covered with blood, and he was motionless.
