Chester nodded in understanding of this plan.

“Now!” cried Hal. “Jump!”

Both lads leaped quickly backward, and as they did so, the barrier–freed of their supporting shoulders–tumbled inward, while the six Austrians sprawled on the ground. For a moment the lads had the advantage and they made the best of it.

Hal’s revolver spoke and one Austrian straightened out in the act of rising. Chester accounted for another, and then both lads sprang in close upon the foe, thus precluding the use of the foe’s firearms.

Hal, grappling with two of the enemy, was giving a good account of himself; but Chester, weak from the loss of blood, was unable to hold his own. A blow from the butt of one of the Austrian’s revolvers and he went to the ground.

At that moment, from their rear, came the sound of rapidly galloping hoofs. Around the bend some distance away dashed a troop of Cossacks, Alexis himself at their head. The giant Cossack took in the situation with one comprehensive glance and put spurs to his horse. The two Austrians who had attacked Chester saw the advancing Cossacks, and, turning, took to their heels.

The two with whom Hal struggled, however, were too busily occupied to notice the approach of reënforcements and sorely, each trying to bring his revolver to bear.

Alexis now jumped from his horse and dashed forward toward the three. He stretched forth two mighty hands and plucked the Austrians off the lad. Raising each high in the air, he stretched wide his arms, and then brought them together with great force. There was a crunch as the heads of the two met with terrific force. Then they hung limp in the giant’s hands. He hurled them from him with a disdainful gesture, and, snatching his revolver from its holster, dropped to his knee and fired two shots in quick succession at the two remaining enemy, who were fleeing down the road.

His aim was true, and as the last of the Austrians bit the dust, Alexis turned to where Chester lay and picked him up gently in his arms. From his canteen he poured water over the lad’s face and soon came signs of returning consciousness. Then he laid him gently on the ground and turned to Hal.

He gazed first at the lad, then at the dead bodies of the enemy and then back to Hal.
