cements. You two had better come in, if you can get away from
your position without being detected. There is no more for you to do
there. You have already accomplished far more than we hoped."

"We are to report to you at Fort Boncelles?"

"It makes no difference. No, I think you had better try to get into
Liege itself and find Major du Chaillu. Good luck!"

"Thank you, lieutenant, and the same to Fort Boncelles! We will try to
escape from here. I should think we ought to have no great trouble,
for the Germans will be busy at their battery again, as soon as they
find the shelling has ceased."

"Yes. We will give them another round or two at intervals during the
night, just to let them know that we still think of them."

When he had finished talking to the fort, Paul proceeded to hide the
telephone as well as he could. Sooner or later the Germans were
certain to come to the garage and it was desirable, for a good many
reasons, that they should find no evidences of the use to which it had
been put. For one thing, it was impossible to tell what was going to
happen. It might well turn out that further use could be made of the
telephone later. And when Paul had done, he felt that it was highly
improbable that the Germans could discover the installation. And then,
just as he finished, Arthur cried out in a voice sharp with alarm, and
Paul rushed up to join him.

The ground about the garage seemed suddenly to have sprouted soldiers.
There were men everywhere, hundreds of them, advancing in loose order.
For a moment Paul hung to the window, fascinated by the sight. Then he
caught himself.

"It's an attack on Boncelles!" he said. "I'm going to warn them if I
have time. I don't care what happens. Arthur, get away from here! If
they come in, pretend you can't speak at all."

And on the word he was off, rushing down again, tearing away the cover
he had provided for the telephone. He had to wait an agonizing two or
three minutes before there was any answer, and once more he was sure
that the wire must have been discovered and cut. But at last there was
an answering voice in his ear, and he gave his news.

"Infantry?" asked Delaunay. "They must be mad!"

"They are planning a surprise attack, I suppose," said Paul. "There
are a great many of them--and I am almost sure I saw some machine guns."

"If their battery hadn't been put out, I could understand," said
Delaunay. "They might have attacked under
