Down they came upon the unprepared Germans, with yells and shouts, their horses running free. At the same time that part of the first Cossack body which still remained reformed and sprang forward.

The Germans turned and fled.

Then from the trenches came forth columns of infantry, supported by field batteries, and in a moment these had opened upon the advancing Russian hors.e.m.e.n; but in spite of this hail of death, the Cossacks did not falter nor pause. Straight up to the mouth of the field guns they rode--sabering the gunners right and left--and in a few moments these had been silenced.

Then the Cossacks turned their attention to the infantry, which, firing with machine-like precision and accuracy, dealt havoc to the ranks of the Russian hors.e.m.e.n and mowed them down.

Several squadrons of Cossacks dismounted and approached the foe on foot, and soon the fighting became hand to hand. The standard-bearer suddenly threw up his hands and fell over backward, the colors fluttering to the ground.

A German officer, thinking to capture the flag, jumped forward, and leaning down laid his hand upon it; but at that moment a hairy, snarling body sprang forward, straight at the German's throat. The latter released his hold on the flag and jumped to his feet to ward off the attack of this strange enemy, which he could not at first make out.

But this new enemy was not to be shaken off. His teeth found their mark, and with a cry, the German tumbled to earth.

The newcomer was Marquis.

Separated from Hal and Chester, Marquis, though a battle dog, had become uneasy at their absence and set out to find them. He had advanced with the second troop of Cossacks, and seeing the dead upon the field, had been trying to pick out the bodies of the two lads.

But when the Russian standard-bearer, almost beside him, had been shot down and the German had leaped for the colors, Marquis had turned from the search of his friends to dispose of his lifelong enemy.

As Marquis' foe went to the ground, a second German sprang forward and, aiming a kick at the dog, also stooped and started to raise the colors.

Marquis, disregarding the kick, seized upon the flag with his teeth at the same moment.

Then came a tug of war. Snarling, and with bristling back, Marquis pulled at the standard. Crying out hoa.r.s.e epithets, the German pulled also; but neither made any headway.

Realizing that the dog was a match for him, the German uttered a fierce imprecation, dropped his hold on the flag, stepped back and aimed his revolver.

But the dog was ready for him. He had released his hold upon the flag almost as soon as had the German, and his canine reasoning told him the German's object. Before the German could pull the trigger, Marquis was ready for him, and hurled his body straight at the German's throat.

He had gauged the distance accurately enough, and beneath the shock the officer was hurled to the ground. He attempted to fight off his four-footed a.s.sailant, but he was no match for the angry dog.

This adversary disposed of, Marquis calmly returned to the flag, picked it up in his mouth, carried it to the commander of the squadron and put it in his hand. The commander took the time to pat Marquis on the head, and utter some words of praise.

But Marquis had no time to listen to these. He had other work to do, and had disappeared almost before the Cossack ceased speaking.

Hither and thither over the field of battle Marquis made his way, sniffing the bodies of the dead, and licking the faces of the wounded.

For an hour he wandered about, and at last his search was rewarded.

From near him came a feeble moan. Marquis p.r.i.c.ked up his ears. Surely he recognized that voice. The moan came again. Marquis hesitated no longer.

He had recognized the voice of Hal. Quickly he sprang to where the lad lay and poked his cold muzzle into the boy's face.

Hal turned feebly on his side and put out a hand before he realized what had touched him. Then he succeeded in raising himself on one arm and threw the other around Marquis' neck.

"Marquis!" he almost sobbed. "Where is Chester?"

Apparently the dog understood his question, for he jumped away and began nosing other bodies nearby. And at last he came upon Chester. The latter also was returning to consciousness. With some difficulty Hal staggered to his feet and made his way to his friend's side. He turned to Marquis.

"Get some water!" he commanded, and paused to see if the dog understood.

Marquis bounded away, and returned a few moments later with a well-filled canteen, in his mouth. Hastily Hal removed the stopper and poured some of the water down Chester's throat. Then he took a drink himself.

Thus refreshed, Chester sat up and looked around. Hal did the same. It was indeed a terrible sight that met their eyes. As far as they could see, bodies of dead and wounded men lay scattered about. Hal shuddered.

"Terrible!" he exclaimed. Then: "I wonder where Alexis is?" He turned to Marquis. "Find Alexis," he commanded.

Marquis understood and trotted away. Chester and Hal now arose and walked slowly after him. At last Marquis, some distance away, set up a loud bark. Hal and Chester approached as rapidly as their exhausted condition would permit.

Marquis was standing directly over the body of the giant Cossack, surrounded by a circle of the enemies whom Alexis had slain in combat.

The giant stirred slightly as the boys approached. Quickly Hal bent over him and, raising his head upon his knee, placed the canteen to his lips.

This brought a sigh from Alexis' lips, and soon he sat up and looked around.

"Well," said he, waving his arm toward the circle of his fallen foes, "you can see what a Cossack does when he fights."

"I see," said Hal briefly. "But come, if you are able to walk. We had better get away from this spot. The battle is not over."

Alexis objected.

"What, a Cossack run!" he demanded.

"But if we stay here we shall probably be killed," replied Chester.

"See," pointing, "even now the Cossacks are retreating in the face of superior numbers. We must go."

"I don't----" began Alexis, but Hal interrupted him.

"Come on," he said, taking him by the arm. "Let's move away from here."

Grumbling and protesting, the giant allowed himself to be led toward the head of the Cossack line, now some distance back. Bullets and sh.e.l.ls were still whistling overhead, for the three were between the opposing forces. None dropped near them, however, and they continued on their way.

Suddenly, from the German line, came the clear call of a bugle.

"Quick!" shouted Hal, hurrying forward. "The Germans are going to charge. We mustn't be caught in between."

But it was too late. Even as the lad spoke, the German cavalry came forward with a rush.

Hal realized in an instant that they would not have time to rejoin the main body of Cossacks, for should the latter advance to meet the charge, they would not do so rapidly enough to come up to them before the Germans. Should the Cossacks retreat, the three could not possibly hope to come up with them.

Fortunately the three were at the extreme east of the battle line; so now, turning quickly, Hal led the way out of danger. When far enough away so that there was little likelihood of being struck by stray bullets, they halted to witness the progress of the battle.

The Cossacks advanced to meet the charge of the German cavalry, and threw it back upon its infantry support, which once more issued from the trenches. German field guns were unlimbered and hurled their sh.e.l.ls screeching at the Russians. The latter were forced to retreat.

The Germans pushed this advantage closely.

"If we only had infantry or artillery here," groaned Alexis, "there would be a different story to tell."

"I'm sure of that," replied Hal; "but to advance in the face of such overwhelming numbers would be foolish."

"True," said Alexis, "but I never like to see a Cossack run from his foes, no matter what their number."
