He took yet a wider curve and before he was aware of the treacherous ground plunged into a swamp bordering one of the creeks.  He stood for a few moments in mud and water to his waist, but he knew that he had passed from the range of the Union fire.  Twigs and bark no longer fell around him and that most unpleasant whizz of bullets was gone.

He pulled himself out of the mire and ran along the edge of the creek toward the roar of the battle.  He knew now that he had passed around the flank of the Southern army and could approach the flank of his own.  He ran fast, and then began to hear bullets again.  But now they were coming from the Southern army.  He threw away the cloak and presently he emerged into a mass of men, who, under the continual urging of their officers, were making a desperate defense, firing, drawing back, reloading and firing again.  In front, the woods swarmed with the Southern troops who drove incessantly upon them.

Dick snatched up a rifle—­plenty were lying upon the ground, where the owners had fallen with them—­and fired into the attacking ranks.  Then he reloaded swiftly, and pressed on toward the Union center.

“What troops are these?” he asked of an officer who was knotting a handkerchief about a bleeding wrist.

“From Illinois.  Who are you?”

“I’m Lieutenant Richard Mason of Colonel Arthur Winchester’s Kentucky regiment.  I was taken prisoner by the enemy last night, but I escaped this morning.  Do you know where my regiment is?”

“Keep straight on, and you’ll strike it or what’s left of it, if anything at all is left.  It’s a black day.”

Dick scarcely caught his last words, as he dashed on through bullets, shell and solid shot over slain men and horses, over dismantled guns and gun carriages, and into the very heart of the flame and smoke.  The thunder of the battle was at its height now, because he was in the center of it.  The roar of the great guns was continuous, but the unbroken crash of rifles by the scores of thousands was fiercer and more deadly.

The officer had pointed toward the Kentucky regiment with his sword, and following the line Dick ran directly into it.  The very first face he saw was that of Colonel Winchester.

“Dick, my lad,” shouted the Colonel, “where have you come from?”

“From the Southern army.  I was taken prisoner last night almost within sight of our own, but when they charged this morning they forgot me and here I am.”

Colonel Winchester suddenly seized him by the shoulders and pushed him down.  The regiment was behind a small ridge which afforded some protection, and all were lying down except the senior officers.

“Welcome, Dick, to our hot little camp!  The chances are about a hundred per cent out of a hundred per cent that this is the hottest place on the earth today!”

The long, thin figure of Warner lay pressed against the ground.  A handkerchief, stained red, was bound about his head and his face was pale, but indomitable courage gleamed from his eyes.  Just beyond him was Pennington, unhurt.
