when we got back to the Holy Loch. The Hunley, that’s our depot ship, carries experts for working on those things. However, they were no sooner taken off yesterday morning than this Drift Station operation came our way and Commander Swanson insisted on having at least six of them put back on straight away.’ Benson grinned. ‘If there’s one thing a submarine skipper hates it’s putting to sea without his torpedoes. He feels he might just as well stay at home.’
‘Those torpedoes are still not operational?’
‘I don’t know whether they are or not. Our sleeping warriors here will do their best to find out when they come to.’
‘Why aren’t they working on them now?’
‘Because before our return to the Clyde they were working on them for nearly sixty hours non-stop trying to find out the cause of the malfunction – and if it existed in the other torpedoes. I told the skipper that if he wanted to blow up the Dolphin as good a way as any was to let those torpedomen keep on working – they were starting to stagger around like zombies and a zombie is the last person you want to have working on the highly-complicated innards of a torpedo. So he pulled them off.’
He walked the length of the gleaming torpedoes and halted before another steel door in a cross bulkhead. He opened this, and beyond, four feet away, was another such heavy door set in another such bulkhead. The sills were about eighteen inches above deck level.
‘You don’t take many chances in building these boats, do you?’ I asked. ‘It’s like breaking into the Bank of England.’
‘Being a nuclear sub doesn’t mean that we’re not as vulnerable to underwater hazards as the older ships,’ Benson said. ‘We are. Ships have been lost before because the collision bulkhead gave way. The hull of the Dolphin can withstand terrific pressures, but a relatively minor tap from a sharp-edged object can rip us wide like an electric can-opener. The biggest danger is surface collision which nearly always happens at the bows. So, to make doubly sure in the event of a bows collision, we have those double collision bulkheads – the first submarine ever to have them. Makes fore and aft movement here a bit difficult but you’ve no idea how much more soundly we all sleep at night.’
He closed the after door behind him and opened the for’ard one: we found ourselves in the for’ard torpedo room, a narrow cramped compartment barely long enough to permit torpedoes to be loaded or withdrawn from their tubes. Those tubes, with their heavy-hinged rear doors, were arranged close together in two vertical banks of three. Overhead were the loading rails with heavy chain tackles attached. And that was all. No bunks in here and I didn’t wonder: I wouldn’t have liked to be the one to sleep for’ard of those collision bulkheads.
We began to work our way aft and had reached the mess hall when a sailor came up and said that the captain wanted to see me. I followed him up the wide central stairway into the control room, Dr Benson a few paces behind to show that he wasn’t being too inquisitive. Commander Swanson was waiting for me by the door of the radio room.
‘Morning, Doctor. Slept well?’
‘Fifteen hours. What do you think? And breakfasted even better. What’s up, Commander?’ Something was up, that was for sure: for once, Commander Swanson wasn’t smiling.
‘Message coming through about Drift Station Zebra. Has to be decoded first but that should take minutes only.’ Decoding or not, it seemed to me that Swanson already had a fair idea of the content of that message.
‘When did we surface?’ I asked. A submarine loses radio contact as soon as it submerges.
‘Not since we left the Clyde. We are close on three hundred feet down right now.’
‘This is a radio message that’s coming through?’
‘What else? Times have changed. We still have to surface to transmit but we can receive down to our maximum depth. Somewhere in Connecticut is the world’s largest radio transmitter using an extremely low frequency which can contact us at this depth far more easily than any other radio station can contact a surface ship. While we’re waiting, come and meet the drivers.’
He introduced me to some of his control centre crew – as with Benson it seemed to be a matter of complete indifference to him whether it was officer or enlisted man – finally stopped by an officer sitting just aft of the periscope stand, a youngster who looked as if he should still be in high school. ‘Will Raeburn,’ Swanson said. ‘Normally we pay no attention to him but after we move under the ice he becomes the most important man on the ship. Our navigation officer. Are we lost, Will?’
‘We’re just there, Captain.’ He pointed to a tiny pinpoint of light on the Norwegian Sea chart spread out below the glass on the plotting-table. ‘Gyro and sins are checking to a hair.’
‘Sins?’ I said.
‘You may well look surprised, Dr Carpenter,’ Swanson said. ‘Lieutenant Raeburn here is far too young to have any sins. He is referring to S.I.N.S. – Ship’s Inertial Navigational System – a device once used for guiding intercontinental missiles and now adapted for submarine use, specifically nuclear submarines. No point in my elaborating, Will’s ready to talk your head off about it if he manages to corner you.’ He glanced at the chart position. ‘Are we getting along quickly enough to suit you, Doctor?’
‘I still don’t believe it,’ I said.
‘We cleared the Holy Loch a bit earlier than I expected, before seven,’ Swanson admitted. ‘I had intended to carry out some slow-time dives to adjust trim – but it wasn’t necessary. Even the lack of twelve torpedoes up in the nose didn’t make her as stern-heavy as I’d expected. She’s so damned big that a few tons more or less here or there doesn’t seem to make any difference to her. So we just came haring on up –’
He broke off to accept a signal sheet from a sailor, and read through it slowly, taking his time about it. Then he jerked his head, walked to a quiet corner of the control centre and faced me as I came up to him. He still wasn’t smiling.
‘I’m sorry,’ he said. ‘Major Halliwell, the commandant of the Drift Station – you said last night he was a very close friend of yours?’
I felt my mouth begin to go dry. I nodded, took the message from him. It read: ‘A further radio message, very broken and difficult to decipher, was received 0945 Greenwich Mean Time from Drift Ice Station Zebra by the British trawler Morning Star, the vessel that picked up the previous broadcast. Message stated that Major Halliwell, Officer Commanding, and three others unnamed critically injured or dead, no indication who or how many of the four are dead. Others, number again unknown, suffering severely from burns and exposure. Some message about food and fuel, atmospheric conditions and weakness in transmission made it quite indecipherable. Understood from very garbled signal that survivors in one hut, unable to move because of weather. Word ‘ice-storm’ clearly picked up. Apparently details of wind speed and temperature but unable to make out.
‘Morning Star several times attempted contact Drift Station Zebra immediately afterwards. No acknowledgment.
‘Morning Star, at request of British Admiralty, has abandoned fishing grounds and is moving closer in to Barrier to act as listening post. Message ends.’
I folded the paper and handed it back to Swanson. He said again: ‘Sorry about this, Carpenter.’
‘Critically injured or dead,’ I said. ‘In a burnt-out station on the ice-cap in winter, what’s the difference?’ My voice fell upon my ears as the voice of another man, a voice flat and lifeless, a voice empty of all emotion. ‘Johnny Halliwell and three of his men. Johnny Halliwell. Not the kind of man you would meet often, Commander. A remarkable man. Left school at fifteen when his parents died to devote himself to the support of a brother eight years younger than himself. He slaved, he scraped, he sacrificed, he devoted many of the best years of his life to doing everything for his young brother, including putting him through a six-year University course. Not till then did he think of himself, not till then did he get married. He leaves a lovely wife and three
