"Bomb, sir?" said the junior, showing an interest which almost made him conversational.
"Sure thing," said the other. "She gave us the tip when she saw him, and that'll be one to put him under."
The First Lieutenant nodded and slipped down the ladder again. Three miles astern came a couple of white specks--the bow-waves of big destroyers pushed to their utmost power. The Captain studied them a moment with his binoculars, and gave a grunt which the helmsman rightly interpreted as one of satisfaction. Slow as she was, the old T.B. had a long start, and was going to be on the spot first. The dark was shutting down, and the shapes of the other T.B.'s on either beam were getting dim.
The night was starlit, and with the wind astern the T.B. made easy weather of it. The two officers leaned forward over the rail staring ahead towards the unseen land. Lights showed on either hand, and occasionally they swung past the dark squat shape of a lit trawler, also bound home.
"Are you going to claim?" asked one of the watching figures. The other paused before replying--
"We-ell," he said, "I'll just report. I think we shook him to the bunt, but it's no good claiming unless you can show prisoners, Iron Cross and all." Another ruminative pause. "Your people were smart on it--devilish smart." Another pause. "What's for dinner?"
A dark mass ahead came into view, and turned slowly into a line of great ships coming towards them.
The T.B. swung off to starboard, and slowed her engines. One by one they went past her--huge, silent, and scornful, while the T.B. rocked uneasily in the cross sea made by their wakes. The Captain watched them go, chewing the stem of his unlit pipe. They were the cause of the day's activity, but it was seldom he met them at close range except like this, in the dark on his way home.
The line seemed endless, more and more dark hulls coming into view, and fading quickly into the dark again. As the last swung by the T.B.'s telegraph bells rang cheerfully, and she jogged off westward to where a faint low light flickered at intervals under the land.
A stranger, if suddenly transplanted to the spot, would have taken some time after opening his eyes to realise that the boat was submerged. He would probably decide at first that she was anchored in harbour. Far away forward, under an avenue of overhead electric lamps, figures could be seen--all either recumbent or seated--and from them the eye was led on till it lost its sense of distance in a narrowing perspective of wheels, pipes, and gauges. All the while there was a steady buzzing hum from slowly turning motors, and about every half minute there came a faint whir of gear wheels from away aft by the hydroplanes. From the bell-mouths of a cluster of voice-pipes a murmur of voices sounded--the conversation of officers by the periscope; while the ear, if close to the arched steel hull, could catch a bubbling, rippling noise--the voice of the North Sea passing overhead.
