Shards and spears of ice reflect the lantern light through the foot-long holes in the hull, but in the centre is something much more disturbing – blackness. Nothing. A hole in the ice. A tunnel.

Honey bends a piece of the splintered oak farther in so Crozier can shine his lantern on it.

“Holy fucking Jesus Christ fucking shit almighty,” gasps the carpenter. This time he does not ask his captain’s pardon.

Crozier has the temptation to lick his dry lips but knows how painful that will be here where it’s 50 below in the dark. But his heart is pounding so wildly that he’s also tempted to steady himself with one mitten against the hull the way the carpenter has just done.

The freezing air from outside rushes in so quickly that it almost extinguishes the lantern. Crozier has to shield it with his free hand to keep it flickering, sending the men’s shadows dancing across decks, beams, and bulkheads.

The two long boards from the outer hull have been smashed and bent inward by some inconceivable, irresistible force. Clearly visible in the light from the slightly shaking lantern are huge claw marks in the splintered oak – claw marks streaked with frozen smears of impossibly bright blood.

From the private diary of Dr. Harry D. S. Goodsir:

11 April, 1845 -

In a letter to my brother today, I wrote - “All the Officers are in great hopes of making the passage and hope to be in the Pacific end of next summer.”

I confess that, however Selfish it is, my own hope for the Expedition is that it may take us a bit longer to reach Alaska, Russia, China, and the warm waters of the Pacific. Although trained as an anatomist and signed on by Captain Sir John Franklin as a mere assistant surgeon, I am, in Truth, no mere surgeon but a Doctor, and I confess further that as amateurish as my attempts may be, I hope to become something of a Naturalist on this voyage. While having no personal Experience with arctic flora and fauna, I plan to become personally acquainted with the life-forms in the Icy Realms to which we set sail only a month from now. I am especially interested in the white bear, although most accounts of it one hears from whalers and old Arctic Hands tend to be too fabulous to credit.

I recognize that this personal Diary is most out of the ordinary – the Official Log that I shall begin when we depart next month will record all of the pertinent professional events and observations of my time aboard HMS Erebus in my capacity as Assistant Surgeon and as a member of Captain Sir John Franklin’s expedition to force the North-West Passage – but I feel that something More is due, some other record, some more personal account, and even if I should never let another soul read this after my Return, it is my Duty – to myself if no other – to keep these notes.

All I know at this point is that my Expedition with Captain Sir John Franklin already promises to be the Experience of a Lifetime.

Sunday, 18 May, 1845 -

All the men are aboard, and although last-minute Preparation is still going on around the clock for tomorrow’s Departure – especially with the stowing of what Captain Fitzjames informs me is more than eight thousand cans of tinned food which have arrived only in the nick of time – Sir John conducted Divine Service today for us aboard Erebus and for as many of Terror’s crew who wished to join us. I noted that Terror’s captain, an Irishman named Crozier, was not in attendance.

No one could have attended the lengthy service and heard the very lengthy sermon by Sir John today without being deeply moved. I wonder if any Ship from any nation’s Navy has ever been captained by such a Religious Man. There is no doubt that we are truly and safely and irrevocably in God’s Hands on the voyage to come.

What a Departure!

Having never gone to sea before, much less as a member of such a Heralded Expedition, I had no Idea of what to Expect, but Nothing could have prepared me for the glory of this Day.

Captain Fitzjames estimates that more than ten thousand well-wishers and Persons of Importance crowded the docks at Greenhithe to see us off.

Speeches resounded until I thought we would never be allowed to depart while Daylight still filled the Summer Sky. Bands played. Lady Jane – who has been staying aboard with Sir John – went down the gangplank to a rousing series of Hurrahs! from we sixty-some Erebuses. Bands played again. Then the cheers started as all lines were cast off, and for several minutes the noise was so deafening that I could not have heard an order had Sir John himself shouted it in my ear.

Last night, Lieutenant Gore and Chief Surgeon Stanley were Kind enough to inform me that it is custom during sailing for the officers not to Show Emotion, so although only technically an officer, I stood with the officers lined up in their fine blue jackets and tried to restrain all Displays of emotion, however manly.

We were the only ones doing so. The Seamen shouted and waved handkerchiefs and hung from the ratlines, and I could see many a rouged dockside Doxie waving farewell to them. Even Captain Sir John Franklin waved a bright red-and-green handkerchief at Lady Jane, his daughter, Eleanor, and his niece Sophia Cracroft, who waved back until the sight of the docks was obstructed by the following Terror.

We are being towed by steam tugs and followed on this leg of our voyage by HMS Rattler, a powerful new steam frigate, and also a hired transport ship carrying our provisions, Baretto Junior.

Just before Erebus pushed away from the docks, a Dove landed high on the main mast. Sir John’s daughter by his first marriage, Eleanor – then quite visible in her bright-green silk dress and emerald parasol – cried out but could not be heard above the Cheers and Bands. Then she pointed, and Sir John and many of the Officers looked up, smiled, and then pointed out the Dove to others aboard ship.

Combined with the Words spoken in yesterday’s Divine Service, this, I have to assume, is the Best Possible Omen.

4 July, 1845 -

What a terrible Crossing of the North Atlantic to Greenland.

For thirty stormy days, even while under tow, the Ship has been tossing, rolling, and wallowing, its tightly sealed Gunports on each side barely four feet out of the water during the downward rolls, sometimes barely making Headway. I have been terribly seasick for Twenty-eight of the last Thirty days. Lieutenant Le Vesconte tells me that we never made more than five knots, which – he assures me – is a Terrible time for any ship merely under Sail, much less for such a Miracle of Technology as Erebus and our companion craft, Terror, both capable of steaming along under the Impetus of their invincible Screws.

Three days ago we rounded Cape Farewell at the southern tip of Greenland, and I confess that the glimpses of this Huge Continent, with its rocky cliffs and endless glaciers coming right down to the Sea, lay as heavily on my Spirits as the pitching and rolling did upon my Stomach.

Good God, this is a barren, cold place! And this in July.

Our morale is Top Notch, however, and all aboard trust to Sir John’s Skill and Good Judgement. Yesterday Lieutenant Fairholme, the youngest of our lieutenants, said to me in Confidence, “I never felt the Captain was so much my companion with anyone I have sailed with before.”
