It still lacked an hour of daylight when the allied fleet drew off, its work accomplished; and behind in the ports now sealed, the anger of the Germans flared forth anew.
The damaged British ships were immediately put into drydock in British ports, and Jack and Frank at once returned to Dover to report to Lord Hastings. The latter greeted the lads with outstretched hands.
"It was a gallant exploit," he exclaimed, "and I am sure both you boys had important roles to play."
"I guess we did, sir," Frank admitted. "At the same time, I'm glad to be safely back here again."
"I suppose, sir," said Jack, "now that the enemy submarines caught outside are without bases, there is little fear of their attempting the trans-Atlantic trip?"
"On the contrary," said Lord Hastings, "they are more likely than ever to do so."
"But they must have a base, sir," protested Frank.
"Not necessarily," smiled Lord Hastings.
"Then how will they replenish their supplies of food and fuel?"
"Well," said Lord Hastings, "if they can snare a victim every three or four days it should be enough. From a merchant ship they can get all the food and fuel they need before sinking her."
