going at full speed. During most of the night this would continue, the liner being kept in almost absolute darkness as an additional precaution. On either side, at some little distance away, ranged a protecting destroyer; and every time the passengers looked in the direction of these slender and speedy little gray vessels, they seemed to breathe more easily.
There was little sleeping done that night aboard the steamer. The exciting time through which the passengers had so recently passed had its effect on their nerves. Then again anxiety played its part, for the daring marauders of the seas had been known to follow a steamer almost into port before making an attack.
But there was no alarm, and toward dawn the two chums, both of whom had managed to secure some sleep at odd times, knew from the commotion that they were entering port.
They turned over, as did many others aboard the liner, with sighs of relief, and went to sleep again, satisfied for the first time in three days that they could find rest without the chance of being aroused by the crash of a torpedo as it struck home.
Finally the air service boys found themselves ashore in England and waiting for a train that would carry them to London.
