The Lieutenant smiled. He remembered the incident when R19, lying in twenty-five fathoms on the bed of the North Sea, was being sought by a dozen hostile destroyers with "distance charges". At any moment the deadly explosive grapnels might have engaged and blown the strongly-built hull to pieces, yet the while the officers played cards, and the men listened to the muffled notes of a gramophone placed in a glass case to obviate any possibility of the Huns detecting the sounds of revelry. "We're in for a busy time, laddie," remarked the Lieutenant. "This German offensive against Riga looks a serious matter, and I hear the Hun fleet is off to co-operate in the Gulf of Riga. For the life of me I can't imagine what these Russians are doing. It's proper dry rot. 'The glorious and bloodless revolution--the birth of a new Russia', as some of our statesmen expressed themselves. I'm afraid Russia's knocked out." "Let's hope not," said Fordyce. "In any case, she did jolly well in the beginning of the war." "Admitted," rejoined Macquare. "Which proves that the old regime, with its acknowledged defects, was infinitely preferable to the equality-for-all policy of the present day. Freedom! They'll find themselves in a pretty mess before they go very far with their chimerical search, you mark my words. Hallo, here's the skipper coming off." The Hon. Derek came alongside in one of the steamboats belonging to the parent ship. Smartly returning the salutes of his colleagues, he stepped on board, followed by his coxswain, who bore under his arm a bundle of charts and a large blue envelope bound with red tape. Lieutenant-Commander Stockdale was in his early thirties, a slimly-built man of medium height and of engaging manners. He had gained his present rank through sheer merit and whole-hearted devotion to the branch of the service in which he specialized. He had unlimited influence behind him; he could easily have secured a "warm billet" on one of the royal yachts, but he had steadfastly set his face against favouritism. Notwithstanding his exalted birth, he was in every sense of the word an officer and a gentleman. A firm disciplinarian, he was ever ready to consider a grievance on the part of his crew. Provided a man was keen and reliable, he could rely upon the skipper's impartiality, but woe betide the luckless individual who attempted to "get to windward" of the Hon. Derek. It was noon before the signal was received for R19 to proceed. Meanwhile a dozen odd jobs had kept Fordyce busily engaged, and almost before he was aware of the fact the submarine, running awash at ten knots, had passed the "gate" in the boom thrown across the harbour's mouth. Then, increasing speed to eighteen, R19 shaped a course N.N.E., across the mine-infested North Sea.
