From the head of the squadron came back the signalled order:
“All troopships zigzag!”
“Looks like a crazy marine waltz!” reflected Danny Grin as he caught a second’s glimpse of this strange maneuver.
Darrin did not turn to see what had become of the submersible at which one of the “Logan’s” shells had been fired. The enemy was undoubtedly unharmed and under control, and there would be another destroyer on the spot in a jiffy. Dave believed that they were not yet in the thick of the Hun trap and he kept a sharp lookout ahead.
“Second destroyer astern of us just signalled a hit,” Dan uttered presently, in a tone of glee.
“Must be the one that we tried for,” was Darrin’s comment.
In the meantime, both the British authorities and the American Admiral at the base port were being constantly informed, through radio messages, of just what was now taking place on this part of the sea.
“Assistance already on the way; watch for it,” came back the reply from the admirals.
“Humph! There’s no vessel that sails that can reach us in season if it didn’t start from port a few hours ago,” was Dalzell’s puzzled comment.
Not very long after that the leading ships of the fleet knew that they were in the thick of the enemy ambush. The courses of several torpedoes were observed, but, thanks to the zigzagging of the vessels, no transport or escort had yet been hit.
