"The Regensburg has been calling us for some time," said the chief signal officer as he came down for his belated "watch" luncheon in the ward-room, "and it looks as though we might expect to see her come nosing up out of the mist any time after two o'clock. She excuses herself for being late at the rendezvous by saying that the fog has been so thick in the Bight that she had to anchor during the night. It's not any too good a prospect for a look-see at Heligoland, for our course hardly takes us within three miles of it at the nearest." It was in a fog that the Hercules had dropped down through the moored lines of the Grand Fleet the previous morning, it was in a fog that she had felt her way out of the Firth of Forth and by devious mine-swept channels to the North Sea, and it was still in a fog that she-the first surface warship of the Allies to penetrate deeply into them since the Battle of the Bight, not long after the outbreak of the war-was approaching German waters.
