With a wild cry he leaped to his feet and dashed forward, a revolver levelled in each hand.
Startled, the Germans turned to face their new foe. One look at Chester's angry features and they recoiled involuntarily.
At the same moment Chester fired—both weapons at once. Two of the enemy toppled over in their tracks.
Now Hal had a quick mind. At Chester's first cry he knew what was up and he grew instantly alert, ready to take advantage of the first opportunity that presented itself.
The opportunity was not long coming.
Lieutenant Steinz, turning to get a view of Chester, for a moment left Hal unguarded. In that instant Hal sprang. Both hands he locked about the German's throat, and squeezed with all his strength. In vain the Teuton squirmed, struck and kicked.
Suddenly Hal released his right hand and drove it into the man's face. At the same moment his left hand shot out and seized the German's revolver. Then he stepped quickly back, levelled the weapon and fired.
"Come on, Chester!" he shouted.
Chester needed no urging.
In a few quick strides he was at Hal's side.
