“What is it?” demanded all eagerly.
“We will retreat to the second compartment,” said the giant, “and I will place myself behind the pillar, which I can see from here.” He stooped and picked up a long heavy iron bar from the ground. “I will have this for my weapon, and invisible in the darkness, if they come in a rush, I can let my bar fall upon their skulls thirty times a minute.”
“Good!” cried Hal, “and at the same time I have another plan. The rest of us shall retreat to the third compartment, leaving Alexis, for the moment, to deal with the foe alone. But Alexis, when I say retreat, you must leave your post and come to the third compartment. Is it agreed?”
“Agreed!” cried the giant.
“All right, then. To your post!”
Quickly the four retreated to the second compartment, where Alexis took up his post behind the large pillar, concealed from view by the narrowness of the entrance between the compartments themselves. The others retreated to the third compartment.
For a long time, it seemed to Alexis, he waited in silence. Then the head of a man appeared through the entrance to his compartment and came toward him. There were more heads behind him.
“Strike, Alexis!” came Hal’s voice from the next compartment.
The giant obeyed. The iron bar rose and fell full upon the head of the first man, who dropped without a cry. Ten times in almost as many seconds the huge iron bar rose and fell again and not once did it fail to find its mark.
The German soldiers could see nothing; they heard sighs and groans; they stumbled over dead bodies, but as they did not realize the cause of all this, they still came forward. So far there had not been a sound to tell those behind what was transpiring in front.
