The horses of the two boys darted forward with the rest of the troop, their ears standing straight up, their manes bristling, their nostrils extended.

Now the troop came close upon the cavalry already engaged; and these men, despite their seeming confusion, parted as though by a prearranged plan, and the reinforcements passed through, and fell upon the enemy with an impact that was not to be denied. Behind, the first troop reformed and now came forward in support.

And once more Hal and Chester found themselves in the midst of battle.

Just before the impact, and as Colonel Anderson brandished his sword aloft and urged his men on with a shouted command, Hal discharged his revolver at a tall Austrian who had taken deliberate aim at Colonel Anderson. The man threw up his hands and with a wild yell toppled beneath the feet of the plunging horses, there to be trampled to death if Hal's bullet had not been enough.

One volley was poured into the Austrians at a command from Colonel Anderson, and then the Italians were upon the foe with drawn sabers. A single volley from the Austrians proved ineffective; Hal and Chester and the commander of the troop were unscathed and the Austrians had no time for another.

Chester parried a blow aimed at him by an Austrian cavalryman, and raising his pistol quickly, toppled him from his horse with a bullet. A second ploughed its way through the chest of another trooper and with his sword the lad caught a blow that at that moment would have descended upon Hal's head.

And so the fighting went, cut, thrust, parry and strike, with an occasional revolver shot in between; and Hal, Chester, and Colonel Anderson, in some miraculous manner, escaping injury.

The Austrians fought bravely, giving blow for blow, and in the center succeeded in breaking through. It was but a mere handful of men who succeeded in this venture, however, and they were immediately cut off from their friends. A demand to surrender went unheeded; and a moment later they had gone down.

A bugle sounded in the Austrian rear. The enemy drew off. It was first blood to the Italians and the troops raised a loud cheer as they dashed forward in pursuit of the foe, who now turned their horses about sharply and fled.

For a hundred yards the Italians pursued, doing great execution with their heavy cavalry swords; and then Colonel Anderson called a halt, for he feared he might be rushing into a trap.
