Suddenly there came a command from Colonel Bluekoff.

“Charge!” he cried.

Immediately the squadron to which the lads were attached hurled itself forward once more, right into the thickest of the fray, in the face of overwhelming numbers. They dashed forward with the fury of madmen, shouting and yelling as they charged.

For a moment the Germans gave back, so terrible was the charge of this mere handful of Cossacks, but for a moment only; then they came on again. From all sides they bore down on the squadron, now completely cut off from the main body of troops, seeking to annihilate them.

There was no order to surrender from the German commander, nor would one have been heeded for the matter of that. At a quick command, the Cossacks formed a little square, back to back, and awaited the attack of the enemy.

It came upon the instant. Upon the Russian horsemen the Germans hurled themselves bravely, cutting and shooting as they came on. The Cossacks gave blow for blow, and in spite of the fierce charge, maintained their unbroken front, though men fell here and there. Unable to pierce this line of steel, the Germans drew off.

Given this little breathing space, Hal and Chester, standing side by side, took in the scene about them. Of the little troop of Cossacks there remained now possibly a hundred men. Their support, the lads could see, desperately engaged elsewhere, would be unable to come to their assistance. It was up to them to fight it out alone.

Colonel Bluekoff was down, having been pierced a few moments before by a German bullet. Among these few men there were, besides Alexis, but two minor officers unharmed. At that moment Alexis himself took command.

His sword raised aloft, he turned flashing eyes upon his men.

“Will we surrender?” he shouted, and answered his own question: “No!”
