‘You know something of cartography, Doctor Bruno?’ Drake says, looking at me with new interest.
‘Only a little,’ I say hastily, as the world disappears into a blank cylinder under the young man’s ink-stained fingers. ‘But anyone with an interest in cosmography is familiar with Mercator’s map. The first true attempt to spread on a plane the surface of a sphere, measuring latitude with some mathematical accuracy.’
‘Exactly,’ the young man says, his face suddenly animated. ‘It is the first projection of the globe designed specifically for navigation at sea. Mercator’s great achievement is to alter the lines of latitude to account for the curvature of the Earth. It means we can now plot a ship’s course on a constant bearing—’ He catches sight of Drake’s face and swallows the rest of his explanation. ‘Forgive me, I am running on.’
‘My clerk, Gilbert Crosse.’ Drake gestures to the young man with an indulgent smile as he eases out from behind the table. ‘Gilbert, these are our visitors newly arrived on the Leicester – Captain Knollys, Sir Philip Sidney and Doctor Giordano Bruno.’ The clerk smiles nervously and nods to each of us in turn, though his red-rimmed eyes linger on me as he locks the papers away in a cupboard and backs out of the room.
‘Very gifted young man there,’ Drake says, nodding towards the door after Gilbert has closed it behind him. ‘Came to me via Walsingham, you know. Take a seat, gentlemen.’
Behind the table, wooden benches are set into the wall panelling. We squeeze in as Drake pours wine into delicate Venetian glasses from a crystal decanter. The young clerk has left a brass cross-staff on the table, an instrument used to determine latitude; my friend John Dee, the Queen’s former astrologer, kept one in his library. I pick it up and, as no one seems to object, I hold one end against my cheek and level the other at the opposite wall, imagining I am aligning it with the horizon.
‘Careful, Bruno, you’ll have someone’s eye out,’ Sidney says, sprawling on the bench, his arm stretched out along the back behind me.
I lower the cross-staff to see Drake observing me with interest. ‘Can you use it?’
‘I have been shown how to calculate the angle between the horizon and the north star, but only on land.’ I set it back on the table. ‘I don’t suppose that counts.’
‘It’s more than many. An unusual skill for a theologian. Can you use a cross-staff, Sir Philip?’ he says, turning to Sidney, mischief in his eye.
Sidney waves a hand. ‘I’m afraid not, Drake, but I am willing to learn.’
Drake passes him a glass of wine with a polite smile. He cannot fail to notice that Sidney does not give him his proper title; both are knighted and therefore equal in status, though you will not persuade Sidney of that. I watch Drake as he sets my glass down. The tension I sensed among the men on deck has seeped in here, even into the refined and polished space of the captain’s cabin. I think of the armed men outside the door.
The latch clicks softly and Drake half-rises, quick as blinking, his right hand twitching to the hilt of his sword, but he relaxes when he sees the newcomers, a half-dozen men with wind-tanned faces, dressed in the expensive fabrics of gentlemen. Leading them is a man of around my own age, thinner but so like Drake in all other respects that he can only be a relative. He crosses to the table and embraces him.
‘Thomas! Come, join us, all of you.’ Drake points to the bench beside Sidney. There is relief in his laughter and I observe him with curiosity; what has happened to put this great captain so on edge? ‘You know Sir Philip Sidney, of course, and this is his friend, Doctor Bruno, come to greet Dom Antonio, whom we expect any day. Gentlemen, I present my brother and right-hand man, Thomas Drake. And this is Master Christopher Carleill, lieutenant-general of all my forces for this voyage,’ he says, gesturing to a handsome, athletic man in his early thirties with a head of golden curls and shrewd eyes. I see Sidney forcing a smile: this Carleill is Walsingham’s stepson, who – though barely older than Sidney – is already well established in the military career that Sidney so urgently craves.
After Carleill, we are introduced to Captain Fenner, who takes charge of the day-to-day command of the Elizabeth Bonaventure; though Drake sails on the flagship, he is occupied with the operation of the entire fleet. Behind Fenner are three grizzled, unsmiling men, more of Drake’s trusted commanders who accompanied him on his famous journey around the globe and have returned to put their lives and ships at his service again.
Knollys is delighted to be reunited with his old comrades; there is a great deal of back-slapping and exclaiming, though the newly arrived commanders seem oddly muted in their greetings. To me and Sidney they are gruffly courteous, but again I have the sense that our welcome is strained, the atmosphere tainted by some unspoken fear.
‘Now that the Leicester is here, I presume the fleet will sail as soon as the tide allows?’ Sidney asks Drake.
Drake and his brother exchange a look. There is a silence. ‘I think,’ says the Captain-General slowly, turning his glass in his hand, ‘we are obliged to wait a little longer. There are certain matters to settle.’
Sidney nods, as if he understands. ‘Still provisioning, I suppose? It is a lengthy business.’
‘Something like that.’ Drake smiles. A nerve pulses under his eye. He lays his hands flat on the table. The room sways gently and the sun casts watery shadows on the panelled walls, reflections of the sea outside the window.
A knock comes at the door; again, almost imperceptibly, I notice Drake tense, but it is only the serving boys with dishes of food. These sudden, nervy movements are the response of someone who feels hunted – I recognise them, because I have lived like that myself so often, my hand never far from the knife at my belt. But what does the commander of the fleet fear aboard his own flagship?
I had been led to believe that all ship’s food was like chewing the sole of a leather boot, but this meal is as good as any I have had at the French embassy. Drake explains that they are still well stocked with fresh provisions from Plymouth, for now, and that in his experience it is as important to have a competent ship’s cook as it is to have a good military commander, if not more so, and they all look at Carleill with good-natured laughter. ‘Although, if—’ Drake begins, and breaks off, and the others lower their eyes, as if they knew what he was about to say.
The tension among the captains grows more apparent as the meal draws on. Silences become strained, and more frequent, though Sidney obligingly fills them with questions about the voyage; the captains seem grateful for the chance to keep the conversation to business. It is only now, as I listen to their discussion, that I begin fully to realise the scale and ambition of this enterprise. I had understood that the official purpose of Drake’s voyage was to sail along the coast of Spain, releasing the English ships illegally impounded in Spanish ports. What he actually plans, it seems, is a full-scale onslaught on Spain’s New World territories. He means to cross the Atlantic and take back the richest ports of the Spanish Main, ending his campaign with the seizure of Havana. Soberly, between mouthfuls and often through them, Drake throws out figures that make my eyes water: a million ducats from the capture of Cartagena, a million more from Panama. If it sounds like licensed piracy, he says, with a self-deprecating laugh, let us never lose sight of the expedition’s real purpose: to cut off Spain’s supply of treasure from the Indies. Without his income from the New World, Philip of Spain would have to rein in his ambitions to make war on England. And if that treasure were diverted into England’s coffers, Elizabeth could send a proper force to defend the Protestants in the Netherlands. I understand now why some of the most prominent dignitaries at court have rushed to invest in this fleet; its success is a matter not only of personal profit but of national security. It is also clear to me that Sidney has effectively found an alternative means of going to war, and that he expects me to follow.
When the last mouthful is eaten, the captains excuse themselves and
