Bowers’ automatic belched forth a stream of fire as he swept the German line. At this distance, a miss was practically impossible. Thus ten shots were hurled among the advancing foes and every bullet found its mark.

“Some shooting, Bowers,” said Hal quietly, as he emptied his revolver into the very faces of the enemy.

There was no time to reload.

Hal clubbed his revolver in his right hand and waited. Bowers did likewise. Neither thought of surrender. In fact, so inhuman and barbarous had been the action of the Germans in the past that it was doubtful whether they would be spared should they raise their hands high in the air.

“Here they come!” cried Bowers.

The first German to poke his head around the wall from the left tumbled back again as the butt of Bowers’ revolver crashed down on his skull.

Fortunately for the two, the granite wall, at the extreme right, touched a steep hill, thus preventing a surrounding movement by the enemy. Nevertheless, it was possible that the enemy might climb the hill and pick Hal and Bowers off with revolver or rifle at will. On the other hand, there was little likelihood that they would have time for such a maneuver before the American troops reached the spot. Besides the left flank, therefore, the only way the foe could reach the defenders was over the wall itself.

One German tried this. Climbing to the top of the wall, he leaped down. As he struck the ground Hal’s revolver crashed down on his head and he lay still.

A moment later two Germans leaped down together. The first Hal met with a blow to the head with his revolver, but before he could turn, the second man seized him in a powerful embrace. Hal kicked out with his left foot, which found the German’s shin. At the same time the lad sent his left fist into the man’s face. Down went the German.

Bowers, meanwhile, was equally hard pressed. Two men he disposed of with his revolver butt and his fists; then the enemy surrounded him. Hal, thinking to join forces with the marine, had moved backward as other enemies came over the wall and just before Bowers was hemmed in, the two managed to get back to back.
