Yet Ramage had seen them here in the middle of the Atlantic, fifteen hundred miles and more from the nearest land, flying with just the same quick, almost nervous wing beats, as though due back at the nest in twenty minutes. It seemed to make little difference whether its destination was fifteen or fifty miles away. Nor fifteen hundred: that was simply the middle of the Atlantic between the Canary Islands and Barbados. To reach one from the other (or any land) the bird had to fly nearly three thousand miles. Did it just fly day and night without stopping? He had never seen one resting on the water like a seagull. And another strange thing was that all those he had seen out in the Atlantic were always flying directly east or west, never to the north or south. On the last voyage, he remembered looking up at eight o'clock in the forenoon to see his first Tropic bird of the passage flying due east, directly over the ship. Then, at four o'clock in the afternoon, he had seen one flying due west, again passing right over the ship. The same bird? His ship's destination, Barbados, had been two thousand miles to the westward. Yet, he remembered, every Tropic bird he had ever seen out in the Atlantic had passed directly over the ship: he had never seen one flying past in the distance. Nor did the bird ever dip down towards the ship, as though looking for a resting place or a tasty scrap of food.
Other species of birds often came on board, though of course they were usually much nearer land. Still, an old Barbados planter he had once spoken to said Tropic birds lived on flying fish and squid, diving down for them. The planter called it the boatswain bird, and the French had several names, different in each island - paille-en-queue, paille-en-cul, and flèche-en-cul. Straw tail, arrow tail - there were a dozen ways of translating it, but the Spanish contramaestre was the nearest to the English boatswain bird.
He waved to Aitken to cross the quarterdeck and join him.
'Horizon looks very empty, sir,' the young Scotsman commented. 'Seems you only realize how big the Western Ocean is when you're looking for someone.'
'We could have overtaken her. Or she could be to the north or south. Or ahead of us.'
'Aye, it'll be only a matter of chance if we sight her. Ten different captains have ten different routes for making this crossing.'
'So you're not very hopeful?'
'No, sir, not with the difference in time.'
Ramage nodded. 'Once she was a complete night ahead of us - ten hours of darkness - there was always the chance of us accidentally overtaking her. And with two or three hundred miles' difference in position, there's the weather, too. She could be stretching along comfortably with a northerly breeze while we are beating against a southerly. She could have a soldier's wind with stunsails set and we could be becalmed.'
'At least we're catching up now!' Aitken gestured to the stunsails, long narrow strips of sail each hanging down from its own tiny boom and hoisted by a halyard out to the end of a normal yard so each stunsail formed an extension of the sail, like an extra leaf at the end of a table.
'Catching up or outstripping?' Ramage mused. 'I can't see Frenchmen hurrying with a ship full of prisoners: they could be treating it all as a comfortable cruise and be in no rush to get back to France - it'll be winter by then, too. They've no idea they're being chased.'
The two men walked aft from the quarterdeck rail, past the companion way leading down to the captain's cabin, then abreast the great barrel of the main capstan, with the slots for the capstan bars now filled with small wedge-shaped drawers containing bandages and tourniquets, ready at hand if they should go into action. Past one black-painted gun on its carriage, and now a second. Then came the binnacle box, like an old chest of drawers with a window on each side, a pane of stone-ground glass revealing a compass which was far enough away not to affect the one on the other side but so placed that the man on either side of the wheel had a good view.
Now the double wheel. Normally the man to windward did most of the work, pulling down on the spokes, but with the ship running before the wind as she was now doing, yards almost square and stunsails drawing, each helmsman paid attention and the quartermaster's eyes never stopped a circuit which covered the luffs of the sails, the telltales streaming out from the top of the hammock nettings, and the compass.
The telltales - Ramage was thankful to see them bobbing so vigorously. Four or five corks threaded at ten-inch intervals on a length of line, with half a dozen feathers embedded in each cork, and the whole thing tied to a rod and stuck up in the hammock nettings, one each side, might not be everyone's idea of beauty, but after those days of calm and light headwinds, they were a wonderful sight.
Now they were passing the captain's skylight - built over the forward side of the great cabin it was a mixed blessing: it provided air and light, and he could hear what was going on, but sometimes the quarterdeck was a noisy place: at night there could be the thunderous flap of sails followed at once by the officer of the deck cursing the quartermaster, and the quartermaster cursing the helmsmen for their inattention... The officer of the deck at night would regularly call to the lookouts (six of them, two on the fo'c'sle, two amidships, and one on each quarter) to make sure they were awake and alert ... Then, Ramage thought sourly, there would be one of those 'Is-it-isn't-it' conversations, probably between the sharp-eyed young Orsini and the officer of the deck. One would think he glimpsed a sail, or land, or breakers in the darkness. The other would be equally sure there was nothing. The muttered but heated debate would be enough to make sure that a drowsy Ramage wakened completely, and often, although he knew there was no land for a hundred miles, he would pull on a cloak and go on deck - there was always a chance ...
Finally the last gun on the starboard side and a few more paces brought them up to the taffrail and time to turn back, both men turning inwards, a habit which ensured no interruption if they had been talking.
'This Count of Rennes, sir?' Aitken said cautiously. 'You've met him?'
'He has been a friend of my family since long before the war began.'
'Ah, so you feel all this personally, too, sir?'
'Yes - but he escaped to England at the Revolution and lived in England until the recent treaty. He still has an estate in Kent. But we're chasing L'Espoir because he's one of the most important French Royalists alive today.'
'And he won't be alive for long if they get him to Cayenne. That Devil's Island is well named, so I've heard.'
'There are two or three islands. I think the French call them the Îles du Salut. One is for convicts and another for political prisoners.'
'I have some notes on Cayenne and the islands,' Aitken commented. 'Taken from some old sailing directions from the Seventies. They probably haven't changed much!'
'You have them on board?'
'In my cabin, sir. I checked as soon as you mentioned where L'Espoir was bound.'
'We'll go over them soon, just in case.'
'That's where you'll catch the rabbit, sir,' Aitken commented. 'A poacher doesn't set a snare in the middle of the field; no, he puts it just outside the burrow. Then you catch the rabbit when it runs for home!'
Ramage stopped for a few moments. Yes, Aitken's simile made sense: why comb the Atlantic? Three thousand miles was the distance, and assuming the Calypso's lookouts could see ten miles on each beam in daylight, they were searching a swathe three thousand miles long and twenty miles wide - sixty thousand square miles. Which, to continue Aitken's simile, must be like walking across a county unable to see over the top of the grass. Cayenne was the burrow: that's where he had to set the noose.
