"Seems likely to me, too," said Dalton. "Wipe us out here, and hold the river for themselves. Our scouts a.s.sured us that there was no large force of the enemy in this region. It must have been gathered in great haste."

"In whatever way it was gathered, it's here, that's sure."

There was a good moon now, and, using his gla.s.ses, Harry saw many details of the battle. The attack was being pressed with great vigor and courage. He saw in a valley numerous bodies of cavalry, firing their carbines, and he saw two batteries, of eight light guns each, move forward for a better range. Soon their sh.e.l.ls were exploding near the hill on which Harry stood, and the fire of the rifles, unbroken now, grew rapidly in volume.

But the men under Sherburne, youthful though most of them might be, were veterans. They knew every trick of war, and columns of infantry swept forward to meet the attack, preceded by the skirmishers, who took heavy toll of the foe.

"If they'd been able to make it a surprise they might have rushed us,"

said Harry.

"n.o.body catches Sherburne sleeping," said Dalton.

"That's true, and because they can't they won't be able to overcome him here. Now there go our rifles! Listen to that crash. I fancy that about a thousand were fired together, and they weren't fired for nothing."

"No," said Dalton, "but the Yankees don't give way. You can see by their line of fire that they're still coming. Look there! A powerful body of horse is charging!"

It was unusual to see cavalry attack at night, and the spectacle was remarkable, as the moonlight fell on the raised sabers. But the defiant rebel yell, long and fierce, rose from the thicket, and, as the rifles crashed, the entire front of the charging column was burned away, as if by a stroke of lightning. But after a moment of hesitation they came on, only to ride deeper into a rifle fire which emptied saddles so fast that they were at last compelled to turn and gallop away.

"Brave men," said Harry. "A gallant charge, but it had to meet too many Southern rifles, aimed by men who know how to shoot."

"But their infantry are advancing through that wood," said Dalton.

"Hear them cheering above the rifle fire!"

The Northern shout rang through the forest, and the rebel yell, again full of defiance, replied. The cavalry had been driven off, but the infantry and artillery were far from beaten. The sixteen guns of the two batteries were ma.s.sed on a hill and they began to sweep the Southern lines with a storm of sh.e.l.ls and shrapnel. The forest and the dark were no protection, because the guns searched every point of the Southern line with their fire. Sherburne's men were forced to give ground, before cannon served with such deadly effect.

"What will the colonel do?" asked Dalton. "The big guns give the Yankees the advantage."

"He'll go straight to the heart of the trouble," said Harry. "He'll attack the guns themselves."

He did not know actually in what manner Sherburne would proceed, but he was quite sure that such would be his course. The wary Southern leader instantly detailed a swarm of his best riflemen to creep through the woods toward the cannon. In a few minutes the gunners themselves were under the fire of hidden marksmen who shot surpa.s.singly well. The gunners, the cannoneers, the spongers, the rammers and the ammunition pa.s.sers were cut down with deadly certainty.

The captain of the guns, knowing that the terrible rifle fire was coming from the thickets, deluged the woods and bushes with sh.e.l.ls and shrapnel, but the riflemen lay close, hugging the ground, and although a few were killed and more wounded, the vast majority crept closer and closer, shooting straight and true in the moonlight. The fire from the batteries became scattered and wild. Their crews were cut down so fast that not enough men were left to work the guns, and their commander reluctantly gave the order to withdraw to a less exposed position.

"Rifles triumphant over artillery," said Harry, who studied everything through his gla.s.ses; "but of course the dusk helped the riflemen."

"That's true," said Dalton, "but it takes good men like Sherburne to use the favoring chances. Now our boys are charging!"

The tremendous rebel yell swelled through the forest, and the Southern infantry rushed to the attack. Harry saw that the charge was successful, and his ears told him so too. The firing moved further and further away, and soon declined in volume.

"They've been beaten off," said Harry.

"At least for the time," said Dalton, "but I've an idea they'll hang on our front and may attack again in a day or so."

"How then are you and I to get through and tell General Lee that this is the place to bridge the Potomac, if it's to be bridged at all?"

Dalton shook his head.

"I don't know," he replied, "and I won't think about it until Colonel Sherburne gives his orders."

The sounds of battle died in the distant woods. The last shot, whether from cannon or rifle, was fired, and the Southern troops returned to their positions, which they began to fortify strongly. Sherburne appeared presently, his uniform cut by bullets in two or three places, but his body untouched. He drew Harry and Dalton aside, where their words could not be heard by anybody else.

"You two," he said, "were to report to General Lee when I thought fit.

Well, the time has come; Harry, you go first, and, at a suitable moment, George will follow. We have news of surpa.s.sing importance. We took a number of prisoners in that battle and we were also lucky enough to rescue several of our men who had been held as captives. We've learned from them that General Meade, after making up his mind to pursue, followed straight behind us for a while, but he has now turned and gone southward in the direction of Frederick. He will cross South Mountain, advance toward Sharpsburg, and attempt to smash us here, with our backs to this swollen river. Why, some of the Federal leaders consider the Army of Northern Virginia as good as destroyed already!"

He spoke with angry emphasis.

"But it isn't," said Harry.

"No, it isn't. Doubtless General Lee will learn from scouts of his own of General Meade's flanking movement, but we mustn't take the chance.

Moreover, we must tell him that this is the place for our army to cross.

If the river runs down in two or three days we'll have a ford here."

"I'm ready to go at any moment," said Harry. "Night helping me, I may be able to ride through the lines of our enemies out there."

"No, Harry, you must not go that way. They're so vigilant that you would not have any possible chance. Nor can you ride. You must leave your horse behind."

"What way then must I go, sir?"

"By the river. We have gathered up a few small boats, used at the crossing here. You can row, can't you?"

"Fairly well, sir."

"'Twill do, because you're not to stay in the boat long. I want you to drop down the stream until you're well beyond the Federal lines. Then leave the boat and strike out across the country for General Lee.

You know the way. You can buy or seize a horse, and you must not fail."

"I will not fail," said Harry confidently.

"You'll succeed if anybody will, and now you must be off. Your pistols are loaded, Harry? You may have to use them."

They did not delay a minute, going down the shelving sh.o.r.e to the Potomac, where a man held a small boat against the bank.

"Get in, Harry," said Sherburne. "You'd better drop down three or four miles, at least. Good-by and good luck."

He shook hands with his colonel and Dalton, took the oars and pulled far out into the stream.

CHAPTER IV

A HERALD TO LEE

When he swept out upon the sullen bosom of the Potomac, Harry looked back only once. He saw two dim figures going up the bank, and, at its crest, a line of lights that showed the presence of the Southern force. There was no sound of firing, and he judged that the enemy had withdrawn to a distance of two or three miles.

The night had turned darker since the battle ceased, and not many stars were out. Clouds indicated that flurries of rain might come, but he did not view them now with apprehension. Darkness and rain would help a herald to Lee. The current was strong, and he did not have to pull hard, but, observing presently that the far sh.o.r.e was fringed with bushes, he sent the boat into their shadow.

He did not antic.i.p.ate any danger from the southern sh.o.r.e, but the old inherited caution of the forest runners was strong within him. Under the hanging bushes he was well hidden, but, in some places, the flood in the river had turned the current back upon itself, and he was compelled to pull with vigor on the oars.
