testing, the giant allowed himself to be led toward the
head of the Cossack line, now some distance back. Bullets and shells
were still whistling overhead, for the three were between the opposing
forces. None dropped near them, however, and they continued on their
way.

Suddenly, from the German line, came the clear call of a bugle.

"Quick!" shouted Hal, hurrying forward. "The Germans are going to
charge. We mustn't be caught in between."

But it was too late. Even as the lad spoke, the German cavalry came
forward with a rush.

Hal realized in an instant that they would not have time to rejoin the
main body of Cossacks, for should the latter advance to meet the charge,
they would not do so rapidly enough to come up to them before the
Germans. Should the Cossacks retreat, the three could not possibly hope
to come up with them.

Fortunately the three were at the extreme east of the battle line; so
now, turning quickly, Hal led the way out of danger. When far enough
away so that there was little likelihood of being struck by stray
bullets, they halted to witness the progress of the battle.

The Cossacks advanced to meet the charge of the German cavalry, and
threw it back upon its infantry support, which once more issued from the
trenches. German field guns were unlimbered and hurled their shells
screeching at the Russians. The latter were forced to retreat.

The Germans pushed this advantage closely.

"If we only had infantry or artillery here," groaned Alexis, "there
would be a different story to tell."

"I'm sure of that," replied Hal; "but to advance in the face of such
overwhelming numbers would be foolish."

"True," said Alexis, "but I never like to see a Cossack run from his
foes, no matter what their number."

It was plain now that the Russian commander realized the futility of
further fighting with his vastly superior foe. The Cossacks gave way
more rapidly and finally turned and began their retreat upon Lodz.

"And here we are right in the middle of the Germans," said Chester.
"What are we going to do?"

"We'll have to try to get back to our lines," said Hal, "and the sooner
we start the better."

"Good," said Chester. "Let's start at once."

Alexis had so far recovered now as to announce that he was feeling
"perfectly fit," and making a slight detour, the three friends, closely
followed by Marquis, set out.

They had progressed possibly half a mile, when Marquis suddenly began to
growl.

"
