, Alexis, Stephan and Marquis, after the battle on the
Vistula, had returned to Lodz without difficulty. The commander of the
Russian river steamer had made it as easy for them as possible. In Lodz
they learned that their regiment had been ordered to the front, and had
been on their way to join it, when the Grand Duke, inspecting his
troops, had come upon them. He immediately had the two lads taken to his
quarters, for he was greatly interested in them. Alexis, Stephan and
Marquis waited without.

At last the Grand Duke spoke. "I have a mission for you, if you are
willing to undertake it," he said.

"Yes, Your Excellency," replied Chester.

"Very good! As you may know, my primary aim, from the beginning of the
war, was an invasion of Hungary--the capture first of Budapest and next
of Vienna. This necessitates the capture of Cracow, in Galicia, and the
forcing of a passage through the Carpathian mountains--a tremendous feat
at this time of year. The investment of Cracow is certain. Even now my
troops are within a few miles of that stronghold, and I had word this
morning that part of it is in flames. Do you follow me?"

"Perfectly, Your Excellency," replied both lads.

"Very well! Now, in some unaccountable manner, my plans have always been

Slav, he should naturally support the Russian cause. He has a strong
following and his men would make first-rate soldiers. We are seeking his
support, and so are the Austrians. However, if it is through his spies
that my plans are being given to the Austrians I would like to know it.
Do I make myself clear?"

"You mean," said Hal, "that you would have us find out just where he
stands?"

"Exactly! He has sent me word that he will espouse our cause, but I fear
he may be double-dealing. Naturally, therefore, you will keep your
identities secret. That is all."

The lads saluted, and turned to depart, but before they could leave the
tent a man in civilian garb entered the tent. The Grand Duke greeted him
warmly and then called to the lads.

"I wish to introduce you to Count de Reslau,
