"Has the evacuation of the brewery taken place?" inquired Von Bingenhammer.
"It has, your excellency," answered Dennis promptly.
"And there is nothing to prevent that Australian Division taking possession of the place—nothing to warn them of the trap?"
"I am expecting their arrival at any moment, your excellency. In fact, it will be difficult for me to escape if I stay here much longer."
"Good," assented the speaker at the other end of the 'phone. "And the land mine is charged ready to blow them back to their antipodes, nicht wahr?"
"Everything is ready as your excellency has ordered it," replied Dennis, with a startled grimace at his brother.
"Then you had better look after your own safety, only remaining to see the mine properly fired, and then come back to His Highness's headquarters. We are preparing a heavy counter-attack for the early hours of the morning. That is all, captain. May the God of the Fatherland protect thee!"
