"Proceed immediately, under command of Admiral Schuler, to Dover Bay, joining submarine flotilla there, to proceed to the Thames for attack British fleet. Flotilla to gather mile off Dover, midnight, Thursday.
(Signed) "SEIBERT."
"I should say that is plain enough," said Lord Hastings, looking up.
"Rather, sir," agreed Frank. "All we have to do is to be at a certain spot at a certain time."
"That's it. And the beauty of it is we do not go with any other vessel. I suppose Admiral Seibert deems it advisable for each vessel to make her way there separately, coming to the surface at the appointed time."
"And shall we be there, sir?" asked Frank.
"Rather," replied Lord Hastings dryly. "First, however, we shall have to find time to run even closer to Dover, take a trip ashore, and notify the Admiralty. Then perhaps we can arrange a little surprise for our friends the enemy."
"That's the way, sir," said Frank enthusiastically. "And I would suggest that the sooner we get under way the better. It may not be so easy to get ashore without being sent to the bottom by one of our own ships or forts."
"Very well," replied Lord Hastings. "You may give the word to proceed at eighteen knots, Mr. Templeton."
Jack gave the order, and the U-16 moved off in the night.
