Now, although this had been no part of Frank's plans, the minute the door crashed in, the two sailors reversed their rifles and sprang over the threshold.

"Crack! Crack! Crack! Crack! Crack!"

The rifles of the three Germans within and the two British sailors spoke almost as one. One of the tars crumpled up in the doorway, while one of the Germans also threw up his hands and slid to the floor.

With wild shouts of anger, the other sailors surged forward and poured through the door in spite of German bullets, which now flew so fast that accurate aim was impossible.

Frank dashed forward with the others. Down went the second German, leaving but one alive. Frank found himself face to face with the latter.

"Stand back, men," he called.

The sailors obeyed.

In one hand the German gripped a revolver, but Frank held this arm with his left hand and straightened it high above the German's head. Thus the German was unable to bring his revolver to bear on the lad.

Nevertheless, his left arm was still free, and he struck Frank a heavy blow in the stomach with his fist. The pain was severe and Frank loosened his hold on the man's revolver arm. With a cry of triumph, the German deliberately lowered his revolver.

Frank, having dropped one of his revolvers, was in a bad way. True, a second was in his belt, but it did not appear that he had time to draw and fire before the German's finger pressed the trigger.
