T-commander Davis was directing the retreat of his men over the sand dunes to their waiting boats on the beach front a mile or so off. German airplanes were making valiant efforts to wipe out the American landing party, but were so hard pressed by the heavy fire from the American battleships at sea that their aim was inaccurate. The U-boat got under way with Lieutenant Bridwell, Jack, and the German pilot in the conning tower. Ted was dividing his time between the engine room and the control chamber, where the other two Germans were stationed under strong guard. Moving very slowly, the U-boat was headed down the canal and very soon emerged into the bay that Jack had found in his exploration of the coast. In full view now was the American fleet from which the landing party had been set ashore---the battleship Tallahassee, the cruisers Detroit and Raleigh, the destroyer _Farragut_ and the submarine _Dewey_. The Tallahassee was lying broadside of the coast with all her monster fourteen-inch guns ready for action. Soon the U-boat had wormed its way safely out into the open sea and was skimming along under the heavy fire of the fleet that was being directed against the German coast fortifications. As the U-boat, with the Stars and Stripes flaunting astern, moved outward, the fleet got under way. Notwithstanding the heavy German fire from the coast defenses the American ships got safely away virtually unscarred in the battle. Fifteen miles out at sea the captured German U-boat came up with the _Dewey_. Jack had a joyous reunion with "Little Mack," Cleary and Binns, Bill Witt, Mike Mowrey and all his other friends aboard the reclaimed American submarine. And then he heard the complete story of his rescue. No sooner had the _Dewey_ appeared upon the, surface, following the successful consummation of Ted Wainwright's plan, than she had sighted the destroyer _Farragut_
