Half way across the open a shot rang out. This was quickly followed by three more. One of the men under Captain Glenn's command pitched forward on his face.

"Forward, men!" cried Captain Glenn, springing forward faster than before.

Captain Jack and Jack Templeton also urged their men to redoubled efforts.

Within the German lines, Jack saw men running forward. Apparently the German officers were trying to get their men in formation to ward off an attack. The enemy had no means of ascertaining the strength of the attacking party, attack was ordered.

Although Frank did not know it, it was the sounds of the firing on shore that had brought the German submarines in the harbor from the depths, upon command, to lend a helping hand if need be.

A volley broke from the three divisions of raiders as they dashed for the German lines. Now that their presence had been discovered there was no reason for further efforts at concealment, and Captain Jack and the other leaders had no mind to be fired upon without returning the compliment.

The result of the volleys, the raiders had no means of determining, but they felt sure that some of the bullets had found human marks. Time after time the Germans fired at the advancing' men, but as the latter showed no signs of giving up the attack the German commander ordered his men to fall back toward the water's edge. He naturally supposed that, his base having been discovered, he was being attacked in force. He could have no idea that the raid was being conducted by a small body of desperate men.

The plan of the German commander was to make a stand at the water edge and then rush his men aboard the flotilla of submarines should he be pressed too closely.

This decision was fortunate for the raiders, for had the Germans made a determined stand the attack must have failed.

Captain Jack's party was the first to reach the settlement. Volley after volley they poured into the Germans. Jack and his men arrived next, and soon Captain Glenn's command, bearing down from the flank, reinforced the first arrivals.
