"Wait a little," cautioned the Lieutenant. "We'll get more of them if you do. Now, let them have it. Ready Aim FIRE!" Down went the Colonel and Major and fully 50 of their men. The Indiana recruits might be green as to tactics, but they knew how to level a gun. The startled rebels ceased yelling, and looked around in amazement in the direction whence the unexpected fire came. A few began firing that way, but the majority started to run back across the "deadening" to the sheltering woods. Groups gathered around the fallen officers to carry them back. "Load as fast as you can, boys," commanded the Lieutenant. "That was a good one. Give them an other." The young Irishmen were wild with excitement, and wanted to rush down and club the rebels, but the Lieutenant restrained them, though he could not get them to reload their guns. As Si was bringing down his gun he noticed the Englishman aiming at the groups about the officers. "Don't shoot them. Fire at the others," Si called out, while he himself aimed at a man who was try ing to rally his comrades. "W'y the bloody 'ell shouldn't Hi shoot them the same has the hothers?" snarled the Englishman, firing into the group. "They're all bloody rebels." By the time the second round was fired the "deadening" was clear of all the rebels but those who had been struck. The others were re-forming on the knoll beyond, and a field-piece was hurried up to their assistance, which threw a shell over at the line. "We had better move off," said the Lieutenant. "They're forming out there to take us in flank, and we can't hold them back. We have done all that we can here, and a mighty good job, too. We have saved a lot of our men and salted a good bagful of rebels. Attention! File left March!" "That was a mighty good introduction for the boys," said Si to Shorty as they moved on through the woods. "They begin to see how the thing's done; and didn't they act splendidly? I'm proud of Injianny." "Sergeant, didn't I do well?" asked Abel Waite, in the tone that he would have inquired of his teacher about a recitation. "I done just as you told me. I kep' my eye on the tall feller in front, who was wavin' his gun and yellin' at the rest to come on. I aimed just below his belt, an' he went down just like I've seen a beef when pap shot him." "Good boy," said Si, patting him on the shoul der. "You're a soldier already." CHAPTER XVI. THE TERRIFIC STRUGGLE THE END OF THE BATTLE OF CHICKAMAUGA. LIEUT. Bowersox, Si, Shorty and the recruits left the woods and entered a large clearing, in the midst of which was a log cabin, with a few rude outbuildings. Over it flew the yellow flag of the hospital service, and beyond could be seen the parked trains and other evidences of the line-of-battle.
