"What is it?" demanded Frank.

"Well," said Jack, "you will notice that the opening in which the Germans lie is entirely surrounded by trees. My idea is to completely surround them, and, at a given signal, fire a volley over their heads. Believing that our force is much greater than it is, and apparently cut off from escape in all directions, the Germans may surrender."

"A good idea," exclaimed Frank. "We will act upon it at once."

Quickly he scattered his men in a wide circle around the German camp. Then, when he felt that all was in readiness, he gave the signal—a shot from his revolver.

Immediately there was a fierce volley from the British, aimed high. The German troops sprang to their feet in a moment; then, at a command from their officer, dropped quickly to the ground again.

Whatever idea Frank had had of a bloodless victory was quickly dispelled, for the German troops—lying flat on their stomachs, fired volley after volley into the woods at their unseen opponents.

This was ineffective, however, because the British were well protected by the great trees. At a command from Frank, which was passed rapidly along the British line, the sailors trained their rifles upon the enemy and fired.

The effect was fearful. Germans toppled over on all sides, and some jumped to their feet and ran toward the trees. Bullets greeted them from all sides, however, and, after making one last stand, the entire German force threw their weapons to the ground as one man.

"We surrender!" called the officer in command.

Slowly the circle of British emerged from the forest and closed in on them. The German officer delivered his sword to Frank without a word; then, at the lad's command, the British surrounded the prisoners and started on their return journey to Boak, where they arrived after a three hours' forced march, and were greeted with acclaim by the sailors who had been left behind. Not a single sailor had been killed in the short but decisive battle, though two had been wounded.
