to a rendezvous, and thereafter as
requisite to their respective stations.

Those from Dunkirk were given their orders by the commodore.

An operation time table was issued to govern the movements of all the
forces. Wireless signals were prohibited, visual signals of every sort
were reduced to a minimum and maneuvering prearranged as far as foresight
could provide.

With few and slight delays the program for the passage was carried out as
laid down, the special aids to navigation being found of great assistance.

The Harwich force, under Rear-Admiral Tyrwhitt, was posted to cover the
operations and prevent interference from the north.

Jack and Frank, having reported to Admiral Keyes upon leaving Lord
Hastings, had received necessary instructions as to their part in the
raid. They had passed the word to the other officers of the Brigadier, who
in turn had informed members of the crew what was about to happen.

There was wild cheering among the British tars on the Brigadier when they
learned they were to have a hand in one of the greatest and most dangerous
enterprises attempted in the whole war. Needless to say, Jack and Frank
also were immensely pleased.

"Tell you what, Jack," said Frank, after they had returned aboard the
Brigadier, "it seems to me as though your work had come to the ears of the
Admiralty with a vengeance."

"Oh, I guess that isn't it," Jack laughed. "They just happened to need

"If you want to know what I think about it," said Frank, "this raid is
going to be one of the greatest blows struck at the enemy."

"It certainly will do the enemy a lot of harm if it's successful," Jack
confessed.

"It'll be successful all right. I can feel that."

"A hunch, eh?" laughed Jack.

"Call it what you like. Nevertheless, I am absolutely certain Admiral
Keyes will not fail. And what are the Germans going to do for submarine
bases if Ostend and Zeebrugge are bottled up?"

"Maybe we'll catch most of them in there," said Jack hopefully.

"They won't be able to get out again if we do," declared Frank.

"Right," Jack agreed, "and the ones that are outside won't be able to g
