“The Germans are planning an aëroplane raid on the English,” said the man, in a low voice. “There is a park of aëroplanes hardly two miles from here, on the road leading to Viviers. They are ready for instant flight.”

“What!” exclaimed Captain Anderson. “Are you sure?”

“Perfectly,” was the reply. “I heard the German officers talking of it only yesterday. They said it would deal a death-blow to the English.”

“And so it would,” said the captain, “unless it can be stopped.”

Hal broke suddenly into the conversation.

“Can you point the approximate whereabouts of this park of machines out to us?” he asked.

“Easily, sir.”

“What’s your idea?” asked Captain Anderson.

“Simply this,” said Hal. “I believe that by a dash we can get through the Germans. They will not expect it, and, if they did, would not expect us to go forward. Consequently, the guard in front is not likely to be vigilant. We have enough men here to make a successful raid on these machines and destroy them.”

“A first-class idea,” said the captain. “We’ll do it.”
