reports, no Asdic contacts, no sign of the German Grand Fleet steaming through the boomââ
âSheâs signalling us, sir!â It was Bentley speaking, Bentley the Chief Yeoman of Signals. He paused and went on slowly: âProceed to our anchorage at once. Make fast to north buoy.â
âAsk them to confirm,â Vallery snapped. He took the foâcâsle phone from the communication rating.
âCaptain here, Number One. How is she? Up and down? Good.â
He turned to the officer of the watch. âSlow ahead both: Starboard 10.â He looked over at Tyndallâs corner, brows wrinkled in question.
âSearch me,â Tyndall growled. âCould be the latest in parlour gamesâa sort of nautical musical chairs, you know . . . Wait a minute, though! Look! The Cumberland âall her 5.25âs are at maximum depression!â
Valleryâs eyes met his.
âNo, it canât be! Good God, do you thinkâ?â
The blare of the Asdic loudspeaker, from the cabinet immediately abaft of the bridge, gave him his answer. The voice of Leading Asdic Operation Chrysler was clear, unhurried.
âAsdicâbridge. Asdicâbridge. Echo, Red 30. Repeat, Red 30. Strengthening. Closing.â
The captainâs incredulity leapt and died in the same second.
âAlert Director Control! Red 30. All AA guns maximum depression. Underwater target. Torpsââthis to Lieutenant Marshall, the Canadian Torpedo Officerââdepth charge stationsâ.â
He turned back to Tyndall.
âIt canât be, sirâit just canât! A U-boatâI presume it isâin Scapa Flow. Impossible!â
âPrien didnât think so,â Tyndall grunted.
âPrien?â
âKapitan-Leutnant Prienâgent who scuppered the Royal Oak .â
âIt couldnât happen again. The new boom defencesââ
âWould keep out any normal submarines,â Tyndall finished. His voice dropped to a murmur. âRemember what we were told last month about our midget two-man subsâthe chariots? The ones to be taken over to Norway by Norwegian fishing-boats operating from the Shetlands. Could be that the Germans have hit on the same idea.â
âCould be,â Vallery agreed. He nodded sardonically. âJust look at the Cumberland goâstraight for the boom.â He paused for a few seconds, his eyes speculative, then looked back at Tyndall. âHow do you like it, sir?â
âLike what, Captain?â
âPlaying Aunt Sally at the fair.â Vallery grinned crookedly. âCanât afford to lose umpteen million pounds worth of capital ship. So the old Duke hares out to sea and safety, while we moor near her anchor berth. You can bet German Naval Intelligence has the bearing of her anchorage down to a couple of inches. These midget subs carry detachable warheads and if thereâs going to be any fitted, theyâre going to be fitted to us.â
Tyndall looked at him. His face was expressionless. Asdic reports were continuous, reporting steady bearing to port and closing distances.
âOf course, of course,â the Admiral murmured. âWeâre the whipping boy. Gad, it makes me feel bad!â His mouth twisted and he laughed mirthlessly. âMe? This is the final straw for the crew. That hellish last trip, the mutiny, the marine boarding party from the Cumberland , action stations in harbourâand now this! Risking our necks for thatâthat . . . â He broke off, spluttering, swore in anger, then resumed quietly:
âWhat are you going to tell the men, Captain? Good God, itâs fantastic! I feel like mutiny myself . . . â He stopped short, looked inquiringly past Valleryâs shoulder.
The Captain turned round.
âYes, Marshall?â
âExcuse me, sir. Thisâerâecho.â He jerked a thumb over his shoulder. âA sub, sirâpossibly a pretty small
