LAURENCE HAD PUT down his ground crew deep in the countryside on the far bank of the Saale, tucked into a well-hidden forested defile, not easily seen from above; they were standing all together, the strongest of the hands in front with axes and sabers and pistols held ready, and Keynes and the runners to the back, the eggs tucked safely in their swaddling and harness near a small screened-off fire.

"We heard the guns going near since you left us, sir," Fellowes said, anxiously, even as he and his men began looking over Temeraire's harness for damage.

"Yes," Laurence said, "they overran our position; we are falling back on Jena." He felt as though he were speaking from a great distance; an immense weariness had hold of him, which could not be allowed to show. "A ration of rum for all the flight crew; see to it if you please, Mr. Roland, Mr. Dyer," he said, letting himself down; Emily and Dyer carried the spirit bottles around, with a glass, and the men each drank their tot. Laurence took his own last, with gratitude; the hot liquor was at least an immediate presence.

He went back to speak with Keynes over the eggs. "No harm at all," the surgeon said. "They could keep like this a month without difficulties."

"Have you any better sense of when we may expect the hatching?" Laurence asked.

"Nothing whatsoever has changed," Keynes said, in his peevish way. "We still have anywhere from three weeks to five, or I should have said."

"Very good," Laurence said, and sent him to look over Temeraire, in case there should be any sign of injury to his muscles, a result of overextending himself, which in the heat of battle or the present sorrow he might not have noticed.

"It was mostly that they took us by surprise," Temeraire said miserably, as Keynes clambered over him, "and those wretched formations; oh, Laurence, I ought to have said more, and made them listen."

"There was scarcely any hope of your doing so under the circumstances," Laurence said. "Do not reproach yourself; think rather how the formation movements might most easily be amended, without causing them great confusion. I hope we may persuade them to heed your advice, now, and if so, we will have repaired a grave fault in tactics, at no more cost than the loss of one skirmish; as painful a lesson as it has been, we will then count ourselves fortunate it was no worse."

They arrived at Jena in the small hours of the morning; the army was drawing up close around the town, withdrawing in upon itself. The French had captured a badly needed supply-train at Gera, and the depots in the town were near-empty. There was only a single small sheep for Temeraire to eat; Gong Su stretched it by stewing, with the addition of some aromatics which he had gathered, and Temeraire made a better meal than the men, who had to make do with a sort of hastily cooked porridge, and hard-baked bread.

There was an ugly murmuring all through the camp, as Laurence walked by the fires: Saxon stragglers coming in from the battlefield were murmuring that they had borne the brunt of the attack, sacrificed to try and hold the French; and worse yet, there had been another defeat: General Tauentzein, retreating from Hof in the face of the French advance, had backed out of Marshal Soult's arms and straight into Marshal Bernadotte's, from frying-pan to fire, and had lost four hundred men before at last escaping. Enough to disquiet any man, much less those who had been counting on an easy, assured victory; there was little sign of that early supreme confidence anymore.

He found Dyhern and the other Prussian aviators having claimed a small ramshackle cottage, hastily deserted by its peasant tenants when the dragons descended upon their fields, for their meager comfort. "I am not proposing any wholesale alteration," Laurence said urgently, laying out his diagrams, sketched to Temeraire's orders, "only what changes can easily be accommodated; whatever risks are entailed in so desperate a change in the final hour can scarcely be measured against the certainty of disaster, if nothing be done."

"You are kind enough not to say, I told you so," Dyhern said, "but I hear it nonetheless. Very well; we will let a dragon be our instructor, and see what can be done; at least we will not be sitting in covert licking our wounds, like dogs after a beating."

He and his fellow captains had been sitting gloomily around the mostly bare table, drinking in silence; now he rallied himself and them both with an immense effort, and by sheer force of personality put fresh heart into them, chiding them for getting into the dumps, and very nearly dragged them bodily outside and back to their dragons. The activity perked up their heads and spirits, Temeraire not least of all; he sat up bright-eyed as they all assembled and gladly threw himself into the exercise, showing them the new flying-patterns which he had devised.

To these Laurence and Granby had contributed little but simplified much; elaborate maneuvers which Temeraire could perform without a thought were simply beyond the physical agility of most Western dragon breeds. Even considerably slowed down, the new patterns gave the Prussians, so long inculcated with their formal drills, some difficulty at first, but the precision which informed their regular practice slowly began to tell, and after a dozen passes or so they were tired but triumphant. Some of the other dragons with the army had crept up to observe, and shortly after their officers came too; when Dyhern and his formation dropped down at last for a rest, they were quickly mobbed with questions, and shortly a couple of other formations were in the air trying their own hand.

Their practice was interrupted that afternoon, however, by a fresh change of plans: the army was concentrating anew about Weimar, with intentions of falling back to protect their lines of communications with Berlin, and once again the dragons would lead the way. An angry grumbling met this news; before now all the marching hither and yon, the changing orders, had been taken in good spirits, viewed as the inevitable shifting course of a war. But to fall back again now pell-mell, as if a couple of small French victories were enough to chase them home, was infuriating to all; and the confusion of orders took on the more unsettling cast of a lack of decision among the commanders.

In this hostile mood, the further news reached them that the ill-fated Prince Louis had taken his position across the Saale in answer to unclear orders by Hohenlohe, which had indeed implied an advance in progress, though this same advance had not been properly authorized by Brunswick or the King; the whole army had never stirred southward in the end, Hohenlohe evidently thinking better of his plans.

"He sent fresh orders to fall back," Dyhern said, bitterly, having heard the news from one of Prince Louis's aides-de-camp, who had just struggled back to camp, on foot, his poor horse having foundered crossing the Saale. "But we were already engaged by then, and our prince had not an hour left of life; so has Prussia thrown away one of her finest soldiers."

They could not be said to be mutinous, but they were very angry all, and worse than that discouraged; the sense of achievement built over the afternoon worn away. They went silently to their several clearings to oversee the work of packing.

The sound of the courier-dragon leaving the covert had begun to be a hateful noise, signifying yet another of the endless futile conferences was under way. Laurence woke to that flurry of wings in the still-black hours of the morning, and rolled out of his tent in bare feet and shirtsleeves to scrub his face at the water-barrel: no frost yet, but more than cold enough to wake a man properly. Temeraire lay sleeping still, breath coming in warm puffs from his nostrils; Salyer looked up alertly when Laurence glanced into the cramped half-sized tent where he and the snoring Allen had kept the night's watch over the eggs: the warmest place in camp, the fabric doubled over and the brazier coals glowing.

They were in covert now a little ways north of Jena, near the eastern edge of the Prussian Army, almost united: the Duke of Brunswick had moved his own forces closer during the night. The whole countryside seemed alive with campfires, whose smoke mingled sadly with the burning town in the distance: something between a panic and a riot had broken out among Hohenlohe's forces the previous night over too little food and too much bad news. The French advance guard had been sighted again just to the south, and several anticipated supply-trains had not arrived; too much, particularly for the Saxons, reluctant allies to begin with and now thoroughly disenchanted.

Separated from the rest of the camp as the covert was, Laurence had not seen much of the unhappy events, but before calm could be restored, fires had caught among the buildings, and now the morning air was acrid and bitter with the floating ash and smoke, damp with dense fog. It was early on the thirteenth of October; almost a month now since their arrival in Prussia, and still he had received no word from England, the post slow and uncertain with the countryside full of armed men. Standing alone with his tea at the edge of the clearing, he looked northwards yearning; he deeply felt the want of connection, so tantalizingly close, and he had rarely known so great a desire to be at home, even when a thousand miles more distant.

The sun was beginning to make some forays towards dawn, but the fog held on grimly, a thick grey mist blanketing all the encampment. Sounds traveled only a short way, deadened queerly, or came seemingly out of nowhere, so one saw ghostly silent figures moving without sound and in another direction heard disembodied voices floating. The men rose sluggishly and went about their work without speaking much one to the other: tired and hungry.

The orders came shortly after ten in the morning: the main body of the army would retreat northwards through Auerstadt, while Hohenlohe's forces kept their position, covering the retreat. Laurence read it silently and handed it back to Dyhern's runner without comment: he would not speak critically of the Prussian command to a Prussian officer. The Prussians were less reticent amongst themselves, loud in their own tongue as the instructions went around.

"They say we ought to give the French a proper battle here, and I think they are quite right," Temeraire said. "Why are we here at all, if not to fight? We might have stayed at Dresden, for all this marching we have been doing; it is as though we are running away."

"It is not our place to say such things," Laurence said. "There may be intelligence which we lack that makes sense of all these maneuvers." This was a small sop to comfort; he did not very much believe it himself.

They were not themselves to move at any time soon, and as the dragons had been fed but poorly three days running now, orders were given not to ask them for any exertions, since at any moment they might be called on for a fresh march or a battle, though that at least seemed now less likely. Temeraire settled to drowse and dream of sheep, and Laurence said to Granby, "John, I am going to go and have a look around from higher ground, outside this blasted fog," leaving him in command.

A flat-topped height, the Landgrafenberg, commanded the plateau and valley of Jena: Laurence took young Badenhaur as his guide again and together they pushed their way up through a narrow winding ravine that led up its wooded slopes, choked in places by wicked-thorned blackberry bushes. Farther up, the track faded out into the tall grasses: no one had mowed the hay here, the hill too steep to bother, though here and there the taller trees had been cut, and level clearings trampled flat by sheep: a couple of them looked up incuriously and trotted off into the bracken.

Sweating, they gained the summit after almost an hour of toil. "So," Badenhaur said, waving his hand inarticulately at the fine prospect; Laurence nodded. A ring of smoke-blue mountains closed off the view in the far distance, but from their ideal vantage point all the bowl of the valley was spread in a circle around them almost like a living map, its gentler hills furred by yellowing beeches and smaller stands of evergreens, a few white-skinned birches stark among them. The fields were mostly brown-yellow and flat, much of the harvest taken in, muted in the thin autumnal light that made the day seem already far advanced and threw the scattered farmhouses into brilliant relief.

A heavy bank of clouds moving steadily westward presently blocked off the morning sun from their immediate view, the shadow creeping up and over the hills. By contrast a fragment of the Saale River nestled among the hills farther away caught the sunlight full-on and blazed incandescent at them, until Laurence found his eyes almost watering with the brilliance. The wind rose, a low fire-crackling sound of crumpled leaves and dry branches, and under that the deeper hollow roar, rather like a sail first belling out, but going on and on without an end. Otherwise there was an immense silence. The air tasted, smelled, strangely barren: no animal fragrance or rot, the ground already hard with frost.

On the side of the mountain from which they had come, the Prussian Army lay in its serried ranks, mostly obscured under the thick blanket of fog; but here and there the sunlight flickered valiantly on bayonets as Brunswick's legions started to draw away north towards Auerstadt. Laurence cautiously went to peer over the opposite side, where the town lay; there was no definite sign of the French, but the fires in Jena were going out: the orange glowing remnants, like coals from this height, faded one by one amid indistinct voices shouting; Laurence could just dimly make out the forms of horses with carts going to and from the river, carrying water.

He stood a while contemplating the ground, pantomiming to Badenhaur with occasional recourse to the handful of French they both possessed, and then they both went still at once; a breath of wind blew the thick climbing pillar of smoke away from the town, and revealed a dragon coming into view from the east: it was Lien, flying over the river and the town in a quick, hummingbird progress, stopping to hover here and again. There was one startled moment where Laurence had the illusion of her flying directly towards them: a moment only, and then he realized it was no illusion.

Badenhaur pulled on his arm, and together they threw themselves flat to the ground and crawled underneath the blackberry bushes, the long thorns scratching and pulling. Some twenty feet in they found a refuge hollowed out from the ground and the bramble: the work of sheep. The branches kept rustling after they had settled themselves in the low depression, and after a moment a sheep came struggling and kicking to join them in the little hollow, leaving behind great tufts of its wool strung from the thorns, a welcome screen. It flung itself down shivering beside them, perhaps finding some comfort in human company in its turn, as the white dragon folded her great wings and let herself down gracefully onto the summit.

Laurence tensed, waiting; if she had seen them, if she were hunting them, a stand of blackberry would hardly keep her off for long. But she looked away, interested rather in the prospect which they themselves had been examining. There was something different in her appearance: in China he had seen her wear elaborate ensembles of gold and rubies; in Istanbul she had been wholly bare of jewels; but now she wore a very different piece, something like a diadem set around the base of her ruff and hooked cleverly under the edges and the jaw, made of shining steel rather than gold, and secure in the center one enormous diamond nearly the size of a chicken's egg, which blazed insolently even in the thin morning light.

A man in a French officer's uniform let himself down off her back and sprang to the ground. Laurence was deeply surprised to see that she had tolerated a passenger, still less one so undistinguished; the officer was bare-headed, dark hair short and thinning, in only a heavy leather coat flung over a chasseur's uniform, high black boots over breeches, with a serviceable sword slung at his waist.

"Here is a fine thing, all our hosts assembled to greet us," he said, his French oddly accented, opening up a glass to survey over the Prussian Army with particular attention to the ranks flowing away onto the road north. "We've kept them waiting too long; but that will soon be attended to. Davout and Bernadotte will send those fellows back to us presently. I do not see the banner of the King, do you?"

"No, and we should not wait here to find it, with no outposts established. You are too exposed," Lien said, in disapproving tones, looking only indifferently over the field: her blood-red eyes were not very strong.

"Come now, surely I am safe in your company!" the officer chided her, laughing, and his smile, which momentarily he turned flashing up to her, gave light to his whole face.

Badenhaur was gripping Laurence's arm almost with convulsive pressure. "Bonaparte," the Prussian hissed, when Laurence glanced at him. Shocked, Laurence turned back around, leaning closer to the bramble for a better look: the man was not particularly stunted, as he had always imagined the Corsican to be from the depictions in the British newspapers, but rather compact than short. At present, animated with energy, his large grey eyes brilliant and his face a little flushed from the cold wind, he might even have been called handsome.

"There is no hurry," Bonaparte added. "We can give them another three-quarters of an hour, I think, and let them send another division onto the road. A little walking to and fro will put them in just the right frame of mind."

He spent most of this allotted time pacing back and forth along the ridge, gazing thoughtfully out at the plateau below, much of the raptor in his expression, while Laurence and Badenhaur, trapped, were forced to endure an agony of apprehension on the behalf of their fellows. A shudder by his side made Laurence look; Badenhaur's hand had crept towards his pistol, a look of terrible indecision crossing the lieutenant's face.

Laurence put his hand on Badenhaur's arm, restraining, and the young man dropped his eyes at once, pale and ashamed, and let his hand down; Laurence silently gave his shoulder a rough shake for comfort. The temptation he could well understand; impossible not to entertain the wildest thoughts, when scarcely ten yards distant stood the architect of all Europe's woes. If there had been any hope of making him prisoner, it should certainly have been their duty to attempt it, however likely to end in personal disaster; but no attack out of the brush could possibly have succeeded. Their first movement would alert Lien; and Laurence from personal experience knew well how quickly a Celestial could take action. Their only possible chance was indeed the pistol: an assassin's shot, from their concealed position, at his unsuspecting back: no.

Their duty was plain; they would have to wait, concealing themselves, and then bear the intelligence back to camp as quickly as they could muster, that Napoleon was closing upon them the jaws of a trap; the biter might yet be bit, and an honorable victory won. But in this task every minute should count, and it was a thorough-going torture to be forced to lie quiet and still, watching the Emperor at his meditations.

"The fog is blowing off," Lien said, her tail flicking uneasily; she was squinting narrowly down towards the positions of Hohenlohe's artillery, which had the mountain in their view. "You should not be risking yourself like this; let us go at once. Besides, you have had all the reports you need."

"Yes, yes, my nursemaid," Bonaparte said absently, looking again through his glass. "But it is a different thing to see with one's own eyes. There are at least five errors in the elevations on my maps, even without surveying, and those are not three-pounders but six with that horse artillery on their left."

"An Emperor cannot also be a scout," she said severely. "If you cannot trust your subordinates, you ought to replace them, not do their work."

"Behold me properly lectured!" Bonaparte said, with mock indignation. "Even Berthier does not speak to me like this."

"He ought to, when you are being foolish," she said. "Come; you do not want to provoke them into coming up here and trying to hold the summit," she added, cajolingly.

"Ah, they have missed their chance for that," he said. "But very well, I will indulge you; it is time we got about the business in any case." He put away his glass finally and stepped into her waiting cupped talons as though he had been used to be handled by a dragon all his life.

Badenhaur was scrambling heedlessly through the bramble almost before she was away. Laurence burst out into the clearing behind him and stopped to look over the prospect one last time, searching for the French Army. The fog was turning thin and insubstantial, wisping away, and now he could see clearly around Jena the corps of Marshal Lannes busy heaping up depots of ammunition and food, salvaging for their shelter wood and materials from the burnt-out husks of the buildings, putting up empty pens. But though Laurence pulled out his glass and looked in every direction, he could see no sign of any other mass of French troops immediately visible, certainly not this side of the Saale River; where Bonaparte meant to get his men from, to launch any sort of attack, he could not see.

"We may yet be able to seize these heights, before he can get his men established," Laurence said absently, only half to Badenhaur. A battery of artillery, from this position, would offer a commanding advantage over the plateau; small wonder Bonaparte meant to seize it. But he had been backwards, it seemed, in getting a foothold.

And then the dragons began popping up over the distant woods like jack-in-the-boxes: not the light-weights they had encountered in battle at Saalfeld, but the middle-weights who made up the bulk of any aerial force: P��cheurs and Papillons, coming at great speed and out of formation. They landed among the French troops securing Jena, something very odd in their appearance. Looking closer through the glass, Laurence realized that they were all of them almost covered over with men: not their own crews only, but whole companies of infantry, clinging on to silk carrying-harnesses, of the same style which he had seen used in China for the ordinary transport of citizens, only far more crowded.

Every man had his own gun and knapsack; the largest of the dragons bore a hundred men or more. And their talons were not empty: they carried, laboring, also whole caissons of ammunition, enormous sacks of food, and, shockingly, nets full of live animals: these, being deposited into the pens and cut free, went wandering about in aimless daze, knocking into the walls and falling over, as visibly drugged as the pigs Temeraire had carried over the mountains, not so very long ago. Laurence sinkingly recognized the damnable cleverness of the scheme: if the French dragons had carried their own rations with them in this manner, there could be any number of them brought along, and not the few dozen which were counted the sum total who could be sustained by an army on the march through hostile territory.

In the course of ten minutes, nearly a thousand men had been assembled on the ground, and the dragons were already turning back for fresh loads; they were coming, Laurence estimated, scarcely a distance of five miles, but five miles with no road, heavily forested and broken by the river. A corps of men would ordinarily have taken a few hours to come across it; instead in minutes they were landing in their new positions.

How Bonaparte had induced his men to consent to attach themselves to dragons and be carried through the air, Laurence could scarcely imagine and had no time to consider; Badenhaur was inarticulately pulling him away. In the distance were rising the heavy-weights of l'Armee de l'Air, the great Chevaliers and Chansons-de-Guerre in all their massive and terrible splendor, on a course for the summit itself, and they were carrying not food nor ammunition but field guns.

Laurence and Badenhaur flung themselves down the hillside and away, both of them skidding and sliding in a cloud of pebbles on the steep trail, clouds of dust and dying leaves stinging their faces as the dragons landed atop the summit. Halfway down the slope, Laurence stopped long enough to risk a final look back: the heavy-weights were discharging battalions by twos and threes, the men running at once to drag the guns into place along the foremost ridge, and the dragons' belly-rigging was being unhooked to deposit great heaps of round-shot and canister-shot beside them.

There would be no challenging them for the summit, and no chance of retreat. The battle would take place as Napoleon had desired, in the shadow of the French guns.
