Harry resolved that he would sleep if he could, but there was no rest for the Invincibles just then. An order came from Beauregard, and, with Colonel Talbot at their head, they took up their arms, marching to one of the fords of Bull Run, where they lay down among trees near a battery. They were forbidden to talk, but they whispered, nevertheless. The ford before them was Blackburn's, and the heavy attack of the Northern army would be made there in the morning.

Harry and the Invincibles were at the very edge of the river. They had been under heavy fire before, but, nevertheless, everything they now saw or heard played upon their nerves. The murmur of the little river was multiplied thrice. Every time a bayonet or a saber rattled it smote with sharpness upon the ear. The neigh of a horse became a fierce, lingering note, and out of the darkness that covered the rolling country in front of them came many sounds, but few of which were real.

For a long time there was movement on their own side of the stream. Troops were continually coming up in the night and taking position. It required no acute mind to perceive that the Southern commander expected the main attack to be made here, and was ma.s.sing his troops in force to receive it. Except at the ford itself the banks of the river were high, but those on the Northern side were higher. A skirt of forest lined the Southern bank, and Harry saw Longstreet and his men march into it, and lie there on their arms. Nearer to him among the trees were the powerful batteries of artillery. Beauregard himself had come and he now had with him seven brigades eager for the attack.

The night was hot and windless, save at distant intervals, when a slight breeze blew from the North. Then it brought dust with it, and Harry believed that it came from the dry soil, trod to powder by the marching feet of a great army, and the wheels of many cannon.

Comparative silence came after a while on his own side of the river. There was no sharp sound, only a low and almost continuous murmur made by the whispering, and restless movements which so many thousands of men could not avoid. But the sound was so steady that they heard above it the croak of frogs at the edge of the stream, and then another sound which Harry at first did not understand.

"What is it?" he whispered to St. Clair, who lay a little higher than he.

"It's a lot of our men crossing the ford. Raise up and you can see them walking in the water. I take it that the general is going to put a force in the bushes and trees on the other bank to sting the Northern army good and hard before it pushes home the main attack."

Standing up Harry saw men wading Bull Run in a long file, every one carrying a rifle on his shoulder. In the hot dim night they looked like lines of Indians advancing through the water to choose an ambush. They were crossing for half an hour, and then they melted away. He could not see one of the figures again, nor did any sound come from them, but he knew that the riflemen lay there in the bushes, and that many a man would fall before they waded Bull Run again.

"Do you think the attack is really coming this time?" whispered Langdon.

"I feel sure of it," replied Harry. "All the scouts have said so and you may laugh at me, Tom, but I tell you that when the wind blows our way I feel the dust raised by thirty thousand men marching toward us."

"I'm not laughing at you, Harry. Sometimes that instinct of yours tells when things are coming long before you can see or hear 'em. But while I'm no such wonder myself I can hear those bullfrogs croaking down there at the edge of the water. Think of their cheek, calmly singing their night songs between two armies of twenty or thirty thousand men each, who are going to fight tomorrow."

"But it's not their fight," said St. Clair, "and maybe they are croaking for a lot of us."

"Shut up, you bird of ill omen, you raven, you," said Happy Tom. "Everything is going to happen for the best, we are going to win the victory, and we three are going to come out of the battle all right."

St. Clair did not answer him. His was a serious nature and he foresaw a great struggle which would waver long in doubt. Harry had lain down on his blanket and was seeking sleep again.

"Stop talking," he said to the other two. "We've got to go to sleep if it's only for the sake of our nerves. We must be fresh and steady when we go into the battle in the morning."

"I suppose you are right," said Happy Tom, "but I find this overtaking slumber a long chase. Maybe you can form a habit of sleeping well before big battles, but I haven't had the chance to do so yet."

Harry did fall asleep after a while, but he awoke before dawn to find that there was already bustle and movement in the army about him. Fires were lighted further back, and an early but plentiful breakfast was cooked. All were up and ready when the sun rose over the Virginia fields.

"Another hot day," said Happy Tom. "See, the sun is as red as fire! And look how it burns on the water there."

"Yes, hot it will be," Harry said to himself. They had eaten their breakfast and lay once more among the trees. Harry searched with his eyes the bushes and thickets on the other side for their riflemen, but most of them were still invisible in the day. Then the Southern brigades were ordered to lie down, but after they lay there some time Harry felt that the film of dust on the edge of the wind was growing stronger, and presently they saw a great cloud of it rising above hills and trees and moving toward them.

"They're coming," said St. Clair. "In less than a half hour they'll be at the ford."

"But I doubt if they know what is waiting for them," said Harry.

The cloud of dust rapidly came nearer, and now they heard the beat of horses' feet and the clank of artillery. Harry began to breathe hard, and he and the other young officers walked up and down the lines of their company. All the Invincibles clearly saw that great plume of dust, and heard the ominous sounds that came with it. It was very near now, but suddenly the fringe of forest on the far side of the river burst into flame. The hidden riflemen had opened fire and were burning the front of the advancing army.

But the Northern men came steadily on, rousing the riflemen out of the bushes, and then they appeared among the trees on the north side of Bull Run-a New York brigade led by Tyler. The moment their faces showed there was a tremendous discharge from the Southern batteries masked in the wood. The crash was appalling, and Harry shut his eyes for a moment, in horror, as he saw the entire front rank of the Northern force go down. Then the Southern sharpshooters in hundreds, who lined the water's edge, opened with the rifle, and a storm of lead crashed into the ranks of the hapless New Yorkers.

"Up, Invincibles!" cried Colonel Talbot, and they began to fire, and load, and fire again into the attacking force which had walked into what was almost an ambush.

"They'll never reach the ford!" shouted Happy Tom.

"Never!" Harry shouted back.

The Southern generals, already trained in battles, pushed their advantages. A great force of Southern sharpshooters crossed the river and took the Northern brigade in flank. The New Yorkers, unable to stand the tremendous artillery and rifle fire in their front, and the new rifle fire on their side also, broke and retreated. But another brigade came up to their relief and they advanced again, sending a heavy return fire from their rifles, while the artillery on their flank replied to that of the South.

The combat now became fierce. The Invincibles in the very thick of it advanced to the water's edge, and fired as fast as they could load and reload. Huge volumes of smoke gathered over both sides of Bull Run, and men fell fast. There was also a rain of twigs and boughs as the bullets and sh.e.l.ls cut them through, and the dense, heated air, shot through with smoke, burned the throats of blue and gray.

But the South had the advantage of position and numbers. Moreover, those riflemen on the flanks of the Northern troops burned them terribly and they were weary, too, with long marching in dust and heat. As the artillery and rifle fire converged upon them and became heavier and heavier they were forced to give way. They yielded ground slowly, until they were beyond range of the cannon, and then, brushing off the fierce swarm of sharpshooters on their flank, they retreated all the way back to the village, whence they had come.

The firing on the Southern side of Bull Run ceased suddenly, and the smoke began to drift away. The Invincibles, save those who had fallen to stay, stood up and shouted. They had won the greatest victory in the world, and they flung taunts in the direction of the retreating foe.

"Stop that!" shouted Colonel Talbot, striding up and down the line. "This is only a beginning. Wait until we have a real battle."

"This has happened for the best," said Happy Tom, "but I'd like to know what the colonel calls a real battle. The fire was so loud I couldn't hear myself speak, and I know at least a million men were engaged. Arthur, how can you be cool enough to bathe your face in that water?"

"It's to make it cool," replied St. Clair, who had stooped over Bull Run, and was laving his face. "I feel that dust and burned gunpowder are thick all over me."

He stood up, his face now clean, and began to arrange his uniform. Then he carefully dusted his coat and trousers.

"Hope you are all ready for another battle, Arthur," said Tom.

"Not yet," replied St. Clair laughing. "That will do me for quite a while."

St. Clair had his wish. The enemy seemed to have enough for the time. The hot, breathless day pa.s.sed without any further advance. Now and then they heard the Northern bugles, and the scouts reported that the foe was still gathering heavily not far away, but the Invincibles, from their camp, saw nothing.

"I suppose the colonel was right," said Happy Tom, "and this must have been a sort of prologue. But if the prologue was so hot what's the play going to be?"

"Something hotter," said Harry.

"A vague but true answer," said Langdon.

Yet the delay was long. They lay all that day and all that night along the banks of Bull Run, and a hundred conflicting reports ran up and down their ranks. The Northern army would retreat, it would attack within a few hours; the Southern army would retreat, it would hold its present position; both sides would receive reinforcements, neither would receive any fresh troops. Every statement was immediately denied.

"I refuse to believe anything until it happens," said Harry, when night came. "I'm getting hardened to this sort of thing, and as soon as my time off duty comes I'm going to sleep."

Sleep he did in the shot-torn woods, and it was the heavy sleep of exhaustion. Nerves did not trouble him, as he slept without dreams and rose to another windless, burning day. The hours dragged on again, but in the night there was a tremendous shouting. Johnston, with eight thousand men, had slipped away from Patterson in the mountains, and the infantry had come by train directly to the plateau of Mana.s.sas, where they were now leaving the cars and taking their place in the line of battle. The artillery and cavalry were coming on behind over the dirt road. The Southern generals were already showing the energy and decision for which they were so remarkable in the first years of the war. Johnston was the senior, but since Beauregard had made the battlefield, he left him in command.

The Invincibles were moved off to the left along Bull Run, and were posted in front of a stone bridge, where other troops gathered, until twelve or thirteen thousand men were there. But Harry and his comrades were nearest to the bridge, and it seemed to him that the situation was almost exactly as it had been three nights before. Again they faced Bull Run and again they expected an attack in the morning. There was no change save the difference between a ford and a bridge. But the Invincibles, hardened by the three days of skirmishing and waiting, took things more easily now.

They lay in the woods near the steep banks, and the batteries commanded the entrance to the bridge. The night was once more hot and windless and they were so quiet that they could hear the murmur of the waters. Far across Bull Run they saw dim lights moving, and they knew that they were those of the Northern army.

"I think things have changed a lot in the last three days," said Harry. "Then the Yankees didn't know much about us. They charged almost blindfolded into our ambush. Now we don't know much about them. We don't know by any means where the attack is coming. It is they who are keeping us guessing."

"But there are only two fords and two bridges across Bull Run," said Langdon, "and they have got to choose one out of the lot."

"Which means that we've got to acc.u.mulate our forces at some one of four places, one guess out of four."

Harry did not speak at all in a tone of discouragement, but his intelligent mind saw that the Northern leaders had profited by their mistakes and that the Southern general did not really know where the great impact would come. The Northern scouts and skirmishers swarmed on the other side of Bull Run, and even in the darkness this cloud of wasps was so dense that Beauregard's own scouts could not get beyond them and tell what the greater ma.s.s behind was doing. Harry was summoned at midnight by Colonel Talbot. Behind a clump of trees some distance back of the bridge, Beauregard, Johnston, Evans, who was in direct command at the ford, Early, and several other important officers were in anxious consultation. Colonel Talbot told Harry that he would be wanted presently as a messenger, and he stood on one side while the others talked. It was then that he first heard Jubal Early swear with a richness, a spontaneity and an unction that raised it almost to the dignity of a rite.

Harry gathered that they could not agree as to the point at which the Northern attack would be delivered, but the balance of opinion inclined to the bridge, before which the command of Evans was encamped. Hence he was sent farther down the stream, with a message for a North Carolina regiment to move up and join Evans.
