"Don't anybody yell! Don't anybody shoot!" called the Colonel in a loud whisper, and it was repeated by the line oflficers. "It will reveal our position. Lie down and keep perfectly quiet. They're overshooting us." The rebel battery in the fort waked up, and, more to show its good will than anything else, began shelling the surrounding landscape. One of our batteries, a mile or so to the rear, which had not had an opportunity to fire during the day, could not resist this challenge, and began throwing shells at the fort with so fair an aim as to draw the attention of the rebel battery to it. The lurid flashes of the muskets, cannon, and shells revealed a belt of jagged abatis several rods wide covering the entire front of the fort and breastworks. "Great Scott!" muttered Si to himself, for he was not on speaking terms with Shorty, and would not alarm the boys; "there's a porcupine nest to git through. How in the Nation are we ever goin' to do it?" "Unroll your blankets and lie down on them," came down the line from the Colonel. "Lay your guns beside you. Don't attempt to stack them. You may attract the attention of the rebels. Everybody keep his place, and be ready to form and move at once." "Stop firing. What are you shooting at?" said a voice of authority in the rebel works. "Who gave the order to fire?" "The men began it themselves," said a second voice. "They heard Yankees moving over there, and commenced shooting at them." "How do you know there are any Yankees out there? I don't believe they have advanced beyond the crest of the hill. I think they are all going down toward Resaca. Haven't you any pickets out there?" "No. We only moved in here this afternoon, and did not know how long we were going to stay. I was ordered to stay here till further orders, to protect the road beyond." "Well, we haven't any ammunition to waste firing at uncertainties. There's enough Yankees in sight all the time for all the bullets we have, without wasting any on imaginary ones. It'll be time enough for you to begin shooting when you see them coming to the edge of the abatis there. Before they get through that you'll have time enough to shoot away all the ammunition you have." "I'm going to see whether there are any Yankees there," said the second voice in the rebel works. "Jim, you and Joe go down to the edge of the abatis and see what you can see."
