Bram: The Western Market of Chang'an, an hour before the drums, and I have never in my life heard so many people being alive at the same time. I want to just stand for a second, because you need to hear this before you need anything else. It is a roar. Not a crowd — a roar, the sound a million people make when they are all buying and selling and arguing and eating in the same nine kilometres of wall, and it comes up off the market like heat off a stone. There is a man to my left selling wine the colour of a garnet out of a Persian jar, and he is shouting the price in an accent from two thousand miles west of here. There is a string of camels — actual camels, roped nose to tail, still shedding the desert — being led between the stalls by a caravaneer in a lapelled coat folded back the way the Sogdians wear them — the Sogdians being the Silk Road's own trading people, and about half the reason this one street sounds like six languages at once. Somewhere close a drummer and a reed-pipe are playing a tune that did not start in this country, and everyone walking past knows it well enough to be slightly sick of it. And the smells — oh, the smells. I name smells first; it is a thing I do; it is the fastest way into a century. Sesame oil and mutton fat and the specific dust of a hundred thousand feet on an unpaved road as wide as a river. Grape wine. Camel. Somebody frying something in a spice I would need a week and a translator to identify. A tea-house. Horse. And, under all of it, a thread of temple incense from a monastery up the ward, where a great bronze bell has just been struck for one of the hours — a deep slow note that rolls out over the tiled roofs and quiets absolutely nothing. I am carrying a water-jar. That is the first fact about the body I am in — the jar, balanced on one hip, a big glazed thing three-colour-splashed in amber and green and cream, heavier full than it looks, and these hands know exactly how to carry it through a crowd without spilling, tilting it off the shoulders that shove past. Young hands. A woman's. There is a good bracelet on one wrist and a very sharp awareness in this body of exactly how much everything in this market costs, which is the awareness of somebody whose household used to be able to afford more of it than it can this year. Let me show you where you are, because it is the most extraordinary address in the world in this exact decade. This is a rectangle of rammed-earth wall about nine kilometres one way and eight the other, laid out on a grid so straight it looks drawn with a rule, and inside it are a hundred and eight walled wards — neighbourhoods, each one a box with a gate, and at dusk every one of those gates is drummed shut and you do not go out again until dawn. Two markets, this one and its twin in the east. The palace along the whole northern wall. And down the middle, an avenue a hundred and fifty metres wide — wide enough that I keep losing the far side of it in the dust. Somewhere between eight hundred thousand and a million people. It is, tonight, the largest city that exists anywhere on the surface of the planet, and it is not close. And it is not what you are picturing. I promise you it is not. Whatever you have in your head for this place, this era — something serene, something on a scroll, something in a museum case — put it down. This is the loudest, richest, pushiest, most foreign-friendly city on earth. There is an astronomer from India running the imperial calendar. There are fire-temples for the Persians and churches for a kind of Christian you have never heard of. The government hires its officials by making them write poetry. This is a civilisation at the exact top of its arc, wearing every good thing it has all at once, in the street, at dusk, and I am standing in the middle of it holding a water-jar and grinning like a fool. And then the drums start. Not one drum. The ward-drums, all of them, all across the city, beginning their evening roll to close the gates — a huge overlapping wooden thunder that rolls across the wards from the near ones to the far ones like weather, and every single person in this market straightens up and starts moving, because when the last drum stops, the gates are shut, and you are wherever you are for the night. It is the most beautiful sound. It is a whole city breathing out in the same minute. I have been in a great many places and I have never once heard a machine that big made of nothing but people and drums and habit. And a name arrives, the way they do — this body's name, and her father's job, which is ward warden, which is why she is out this late and nobody stops her: her father runs one of the hundred and eight gates, and his name opens them. She is nineteen. She is going home with the water because the night-soil carts came late and the well queue was long, and tomorrow she will do it again. So. Hello. I'm the ward warden's daughter, and I am carrying water home through the greatest city in the world on an ordinary evening, and both of us — her and me, the me who is watching from behind her eyes — both of us think this is going to go on forever. It has thirteen months. This is Chronicles — history, lived from the inside. Not the dates and the names cut into the monument, but the morning it actually happened, close enough to touch. We drop you into the room where the world turned, and we make you feel why it still matters now. And there's only one honest way in: to actually be there, in a body, on the day. So one traveller goes where the rest of us can't — the same soul, life after life, moving through all of history, waking inside someone who was really there. I'm the Traveller. Episode fifteen. The State Is Shattered — the eight years the golden age turned to ash, and the one man on the road who wrote it all down. Put that market down for a minute — I'll bring you back to this city, I promise, though when I do it will be so quiet you won't recognise it. I want to take you back first. Not far. Just far enough to answer the only question that actually matters, which is: what could possibly bring THIS down? Because the astonishing thing about the answer is that it is completely knowable, and almost nobody outside China has ever heard it. So, first: the wrong picture, and how wrong it is. When people in the West think of old China they think of something delicate and closed and a bit sleepy — porcelain, misty mountains, a serene emperor. Every part of that is wrong for this moment. The dynasty is called the Tang, and in the middle of the eighth century it is the most populous, richest, most literate, most heavily-militarised and most cosmopolitan state on the planet, and it is not remotely serene. It runs a professional frontier army of half a million men. Its capital — the one you were just standing in — is the eastern end of the Silk Road, and a third of the resident merchants speak Sogdian or Persian or Turkic in the street. It is confident enough to be run, in places, by foreigners: Turkic and Khitan generals on the border, a Persian refugee community, Japanese students in the schools, that Indian astronomer I mentioned running the calendar. And it examines its civil servants on their ability to write verse — which means the men who administer the empire are, quite literally, poets. Hold that fact. It is going to become the most important thing in this whole story, and right now it just sounds charming. And it is big in a way that is hard to make your imagination do the work on. The capital is a rectangle of rammed-earth wall nine kilometres by eight, laid out on a dead-straight grid of a hundred and eight walled neighbourhoods — the wards — each one drummed shut at dusk, with two vast enclosed markets and, down the central axis, an avenue a hundred and fifty metres across. Somewhere between eight hundred thousand and a million people live inside those walls, which makes it, by a wide margin, the largest human settlement anywhere on earth. There are Zoroastrian fire-temples and Manichaean congregations and a strain of Christian you have never heard of, all tolerated, all trading. There is wine from Central Asia in the shops and there are dancers from Samarkand in the wine-shops. The state runs the fastest postal relay on the planet, built to carry military intelligence, and occasionally — this is true, and it is going to matter — bent to carry fresh fruit to a consort who liked it. This is a machine for being rich and open and enormous, running at the very top of its capacity. This is a genuine high-water mark of human civilisation. Full stop. And it is thirteen months from the fire. Now — the second thing, and this is the one nobody tells you, so lean in. The catastrophe that is coming was not smuggled in from outside. It was built, deliberately, by the state it destroyed, out of two administrative decisions that both looked clever at the time.

Decision_one: the border. For centuries the frontier had been held by a farmer-militia — men called up from their fields, rotated to the border and sent home — the fubing, the levy. By the early eighth century it could not hold the line any more, so between about 710 and 742 the Tang replaced it with ten permanent professional armies, each under a single regional commander who held military and tax and civil power over his whole stretch of frontier. Those commanders had a title — jiedushi, the military governors — and the system worked beautifully. The border went quiet. The empire got rich. It had also, without quite noticing, built ten small states inside itself, each with its own revenue and its own soldiers who were loyal to their general and paid by him.

Bram: Decision two — and this is the elegant, fatal one. The chancellor who ran the government for nearly twenty years, a man called Li Linfu, made it deliberate policy to hand those great frontier commands to non-Chinese generals. His reasoning was pure court politics: a foreigner had no path into the civil service, no way to climb the literary ladder to the capital, and so could never come back and threaten him, Li Linfu, in the chancellery. It solved his problem perfectly. And it meant that the most powerful soldiers in the empire were, by design, men the court could arm but could never fully bring home. And the man that policy was built to produce was named An Lushan. Born on the frontier to a Turkic mother and a Sogdian father, raised in the border markets, a market interpreter who spoke six languages, a soldier, then a governor — and by the year 751 he held three of the ten commands at once. A third of the entire frontier army answered to one man's seal. Sit with the shape of that for a second. Nobody smuggled a barbarian in over the wall. The court hired him, promoted him, decorated him for real victories on the frontier, and adopted him into the imperial family — because a clever policy, working exactly as designed, needed a man precisely like him and went out and made one. The system did not fail to stop An Lushan. The system was built to raise him. And just so you have the size of it — hold this against what was happening in the world you were probably taught was the centre of things. In the year An Lushan raised his armies, in Europe, Pepin the Short is three years into being king of the Franks and his son Charlemagne is a boy of about thirteen. Rome is a town of maybe thirty thousand people living in the ruins of itself. Constantinople is the biggest city in Christendom and it is busy smashing its own religious images. The Baghdad of the storybooks does not exist yet — the caliphs who will build it have only just taken power. The eighth century is the Dark Ages, and it is — in Europe. Meanwhile, on the far side of the world, the largest and most brilliant state that has ever existed is about to fall into the deadliest war the human race will fight before the twentieth century, and almost nobody in the West will ever hear that it happened. Right. Now you have the height of the thing. Let me take you into a warm room, and introduce you to the two people the whole disaster is going to be blamed on — so that you can decide for yourself, before anyone tells you what to think, whether the verdict is fair. The Huaqing hot springs, in the first week of winter, and I am carrying a flame on a little dish and trying very hard not to breathe on it. This body is sixteen. He is a palace lamp-boy — three weeks into the best and most terrifying job in the world — and his entire life right now is a lit wick and a walled courtyard at the foot of a mountain where the hot springs come up out of the ground and the emperor spends his winters. The air is sulphur off the pools and sandalwood laid over the top of it, and there is a squeak — his own new shoes on the lacquered floor, which he hates, because you are not supposed to make any sound at all. His whole job, the entire content of it, is: keep the lamps lit, do not spill the oil, and do not be seen. And he is magnificent at not being seen. He is furniture with hands. Which is exactly why he sees everything. And what he can see, through a gauze screen, in the warm lamplight he is feeding, is two people making music. There is an old man sitting very upright with a flute — a dizi, a cross-blown bamboo flute — and he is not very good tonight and he knows it, and he keeps stopping. And there is a woman across from him, full-figured, her hair up with combs and a fresh flower in it even in winter, and she has a small drum across her knees, and every time he stops she waits, without a single flicker of impatience, and then gives him the phrase back, slowly, on the drum, so he can find where he lost it. And he stops again, and this time he speaks, in a mild, put-upon voice, to the woman, without looking up.

Xuanzong: It is the phrase that is wrong. Whoever set it down set it down badly.

Bram: And the woman does not even lift her head from the drum.

Yang_guifei: The phrase is perfect. You come off it a beat early because you are afraid of it. Breathe before the turn this time, and stop blaming the man who wrote it four hundred years ago.

Bram: And he glares at her, and she keeps her eyes down, and two of her fingers go on keeping time against the drum-skin, and he tries it once more — and this time he breathes before the turn, and the little run of notes comes out whole and lands, and he cannot help himself.

Xuanzong: ...You were right. You are always right about this, and it is a genuinely terrible quality in a consort.

Yang_guifei: Again. From the top. While you still remember how you did it.

Bram: And he mutters it, picking the flute back up, to nobody, delighted.

Xuanzong: "From the top." Forty-four years on the throne, and I am told "from the top."

Bram: That's the emperor. That old man not-quite-managing his own flute is Xuanzong, who has sat on the throne for forty-four years, longer than anyone in the dynasty, who took power in a palace coup when he was twenty-five, and who is genuinely, seriously, one of the great rulers of the age. And he is a much better musician than the tune is currently suggesting, and he does not care in the slightest that a servant might hear him fail, because in this room he is not the emperor. He is a man of seventy who runs a conservatory of musicians for the joy of it and has found, late, the one person he most likes to be wrong in front of. And she is Yang Guifei. And I want you to look at her the way this boy looks at her, which is: as a person in a room, not as a verdict. She is thirty-five. She is a trained musician — that is the actual ground of this, the thing that has held an elderly, artistically obsessive man for eleven years is not her face, it is that she is the only one at this court who can genuinely play with him. She corrects his fingering. He argues. She is right. He knows she is right, and does it her way, and is happy. There is a plate of something between them that neither has touched — and yes, if the courier got through the passes, there is fresh lychee on it, cool and cut-grass sharp, which is its own famous story for another time. It is a completely ordinary evening between two people who have been the centre of each other's lives for a decade. There is nothing in this room that could bring down an empire. That is the single most important thing I can show you, and I am showing it to you now, before anyone gets the chance to tell you otherwise. The boy shifts his weight and the shoe squeaks and he freezes, and the emperor, without stopping playing, lifts one hand off the flute a few inches — it's all right, stay — and puts it back. And that is the whole of the interaction between the most powerful man alive and a sixteen-year-old, and it is kind. And there is one more thing in this room, and the boy's eyes keep sliding to it, because it is the biggest thing in the room in every sense. There is an enormous man reclining on a couch along the wall, laughing at something, and being brought a third bowl of wine. He is vast — the single most-remarked thing about him is his size — a mountain in Tang court robes, a broad Central Asian face, a great beard, a high-bridged nose, and when he laughs the whole couch complains about it. And the court adores him. He is warm and he is funny and he does an outrageous impression and he can, despite everything, dance — a fast whirling Sogdian dance that makes the whole room laugh with delight. And the boy remembers something, because he was here for it, three years ago. He remembers the night they made this enormous general the son of that woman across the drum. Formally adopted, a man of fifty, by a woman sixteen years younger — and on the third day, the way you would for a real baby, the palace ladies wrapped him in swaddling-clothes, all of him, this vast laughing man bundled up like an infant and carried about the courtyard, and everyone shrieked with laughter, and the emperor sent gifts and laughed hardest of all. The boy laughed too. He had no idea what any of it meant. He still doesn't. I do. I am watching that enormous man laugh a half-second after everyone else laughs — every single time, half a beat late — so that he is watching the room the whole time it thinks he is being amused by it. And I am watching how completely the clowning works. A frightened court forgives a funny fat foreigner anything. Nobody in this room is afraid of the man on the couch. That is the most dangerous thing about him, and he built it himself, joke by joke, over years. But that is not tonight. Tonight is a flute, and a drum, and two people who like each other, and a boy with a lamp keeping the light steady so they can see the music. Let them have it. In thirteen months every person in this room is running for their life, and two of the three are going to be dead inside two years, and one of those two is going to be blamed, forever, for all of it. So look at her keeping time with two fingers, once more, while she still can. There. That's the woman. Remember her exactly like this. Let the boy trim the lamp. I need to take you up out of that warm room, because a clock has started, and you should see it, because it is the reason for everything that follows and it is not the reason you would guess. First, that enormous general — because I need you to stop hearing the word barbarian every time he comes up, since it is going to do a lot of dishonest work in this story if I let it. An Lushan was born of the Sogdians. And the Sogdians were not some horde off the steppe. They were the trading nation of the Silk Road — a network of Iranian-speaking merchant cities around Samarkand and Bukhara, whose families ran the caravan trade all the way from Persia to the gates you were standing in, and whose people lived in Tang cities in their own neighbourhoods under their own headmen. They supplied the empire with horses and wine and dancers and silverwork and, above all, with soldiers and interpreters. They were Zoroastrian and Buddhist and Manichaean by turns. They were not outsiders to the Tang world. They were the Tang world's connective tissue — the thread that made the most cosmopolitan city on earth cosmopolitan. An Lushan came up through exactly that world: a frontier market interpreter, six languages, who caught a general's eye and rose on sheer ability. Keep that. He is not an infiltrator. He is a product. Now the clock. In the year 752, Li Linfu — the chancellor whose clever foreign-general policy we talked about — dies. And the man who takes the government is a piece of work named Yang Guozhong. He is Yang Guifei's second cousin, and that is the entire basis of his career: he is a provincial gambler with no ability anyone remembers and no base of his own except her favour, and he has climbed to the top of the state on it. He holds, at his height, some forty offices at once. And he needs An Lushan destroyed — partly out of rivalry, partly because a foreign general with a third of the army is a threat to a chancellor with nothing but a cousin — and so from 753 he tells the emperor, over and over, in public, that An Lushan is planning to rebel. And here is the trap, and it is beautiful and it is horrible. The emperor does not believe him. Xuanzong loves An Lushan and will not hear a word against him — at one point he even considers making him chancellor. So the accusation fails. Completely. It changes nothing at court. But it does exactly one thing, and it is fatal: it tells the most powerful soldier in the empire that the second most powerful man in the empire has publicly committed to killing him — and that the seventy-year-old emperor who is the only thing protecting him is not going to be there very much longer. Put yourself in the enormous man's chair for one second. You have three armies. You have an enemy in the chancellery who has said, out loud, that he is going to destroy you. And your one protector is seventy. The day that old man dies, you are a dead man with a hundred and fifty thousand soldiers. That is not a tyrant's ambition. That is arithmetic. And a man in that chair does not have a safe move left. Come and stand in the cold with me, and watch him run the numbers. Fanyang, the north-eastern frontier, a thousand miles from that warm room, in the middle of December — and the cold up here is a different animal entirely. I am on a horse. Of course I am on a horse; I cannot ride; every era assumes I can ride; this body can ride in its sleep and frequently does. This is a Xi cavalry trooper — the Xi are one of the steppe peoples the Tang recruits up here — fifteen years on this frontier, and everything about him is frozen: frozen leather, frozen beard, a wind coming straight off the grasslands with nothing between here and Mongolia to slow it down, and it gets in under the lamellar armour and sits against the skin. And there is a sound, under everything, that I feel in the chest before I hear it with the ears — a great barrel drum, struck over and over, the muster-drum, and it goes through ten thousand horses standing in the dark until they are all breathing on the same beat. And this body is happy. That is the thing you have to understand from the inside. He is not a rebel and does not think of himself as one and has no idea, tonight, that he is about to become one. He is a soldier whose pay comes late, whose general he would follow into the sea, and who has just been told they are marching south — and south is where the loot is. South is the rich country. He reads a muster the way a clerk reads a ledger: who is being paid, who is being promised, which units are drawn up where. And this muster is enormous, and it is being paid on time for once, and that tells him something good is happening even if nobody has told him what. And then the general rides down the line, and everybody straightens. And I get to do the thing this whole show exists to do — I get to see him up close, at the exact moment that matters, from six feet away, on a horse, in the cold. And he is not the man from the couch. That is the revelation, and it lands in my chest like the drum. The court knows a warm, laughing, slightly-too-eager fat man who dances. This is not that man. This is a huge, still, watchful commander with no charm in him whatsoever, sitting a horse that has been chosen to carry his weight, and when he speaks to the men it is flat and fast and frontier-blunt and there is nothing to laugh at anywhere in it. The clown is a costume. He put it on for the court because a court that fears a competent foreigner will forgive an amusing one, and he wears it for years, and he must despise every minute of it — and up here, in the cold, with his own men, he takes it off. This is who he actually is. And I understand, watching him, that the buffoon and the general are the same brilliant, cornered man, and that neither one is the lie. And then he tells them the thing, and he does it in about four sentences, flat, no speech in it, the way you would give a marching order.

An_lushan: There is an edict. It is under the seal and it is in my hand. The chancellor Yang Guozhong is a traitor to the throne, and we are commanded to go to the capital and take him out of it.

Bram: And a man near the front — a company officer, older — calls back the one question that matters, and he is not being insubordinate, he is being a soldier.

The_officer: And the son of Heaven himself? What are the orders touching the emperor?

An_lushan: The emperor is exactly who we are marching for. We are the loyal ones. Remember that, all of you, because it will be true right up until the morning it stops being true, and none of you will notice the morning.

Bram: And then the only order that is not a lie.

An_lushan: Mount up. We ride at the drum. South, and do not spare the country you ride through — it is going to feed us all the way to the throne.

Bram: And the trooper beside me believes it completely, because why would the general lie, and because it is the kind of thing that is true often enough. The edict is forged. There is no edict. But the shape of it is loyal — we are not rebelling, we are rescuing the emperor from a bad minister — and that shape matters, because it lets a hundred and fifty thousand men march south telling themselves they are the loyal ones. And maybe, on that first cold morning, the man who forged it is telling himself the same thing. Here is what I can see that the trooper cannot. This is a man doing a sum. He has an enemy who has promised to kill him and a protector who is running out of years, and he has worked out that the only move that does not end with his head on the capital wall is to move first, now, while the old man still lives and the interior is soft. And the interior is soft. That is the other half of the sum, and it is the empire's own doing: all the real soldiers are up here, on the frontiers, in the ten commands. Behind him, between here and the throne, there is no field army worth the name. The farmer-militia is a memory. He has done the arithmetic and the arithmetic says go. So the drum changes. And the trooper feels his horse gather under him, and the whole enormous dark mass of the army begins to move, all on the same beat, south, toward a warm rich country with no one in it to stop them — and the trooper is grinning, because there is loot at the end of this, and the man who made him is grinning at nothing, because there is survival at the end of it, maybe, if he is fast — and neither of them can see the thirty-six million people this decision is standing on. It is the sixteenth of December, 755. Feel the ground tilt. It is going to keep tilting for eight years. Ride south with me, fast, because the army does, and the speed of it is the story of the next six months. There is nothing to stop him. That is the whole of it. He comes down out of the north-east and the interior folds like wet paper, because everything the empire spent a century building its safety on is in the wrong place — the soldiers are on the borders and the general is now bringing the border to the middle. Within about five weeks he takes Luoyang, the great eastern capital. And in February, in the city he has just taken, he stops pretending this is a rescue and crowns himself. New dynasty, new name — Yan — a rival emperor, a rival claim to the Mandate of Heaven itself, which in this world is not a metaphor. It is the working theory of who is allowed to rule, and everybody, on every side, is now watching the sky to see whether Heaven has changed its mind. And the court, back in Chang'an, does the thing courts do, which is assume it will all be fine by winter. It will not be fine by winter. Between the rebel army and the largest city on earth there is exactly one thing left, and it is a mountain pass, and it is held by a good general with a good plan, and the plan is about to be overruled by a frightened man who has never held a spear in his life. Come and stand in the pass. Tong Pass, the seventh of July, and from where I am standing you cannot lose this position, which is exactly why we are about to. This body is a staff officer — an aide to the general who holds the pass — and he knows terrain the way the lamp-boy knew corridors. And the terrain here is a gift. Tong Pass is a narrow defile where the road squeezes between the river and the heights, and an army sitting in it cannot be flanked and cannot be rushed; a handful of men can hold it against a host. The general commanding here is called Geshu Han. He is a frontier man himself, a Turkic commander, ill — he has had a stroke — and he is furious, and he is completely right. His plan is the only sane plan in the entire war: sit here. Hold the pass. Let the rebellion rot behind the rebel army, let its supply lines stretch and fray, let the loyal provinces in the east close in on its back, and do not, under any circumstances, come out of this rock and fight in the open, because in the open the rebel cavalry are better than ours and we lose. And the orders keep coming from the capital telling him to come out and fight. I want you to see who is really giving those orders, because he is nowhere near this pass. It is the chancellor, Yang Guozhong. And here is the shape of the man, and it is one of the sharpest shapes in the whole story. He is not stupid. He is a frightened man who climbed to the top on his cousin's coat-tails and knows, correctly and permanently, that he is one death away from being nothing again — and so every single decision he makes is insurance for himself, and the empire is just the thing that gets spent buying it. And right now he looks at Tong Pass and he does not see the one position that can save the capital. He sees a loyal general sitting a day's march away with a large army — a general who, if this goes on, might decide the person really to blame for all this is the chancellor, and turn that army around. So Yang Guozhong would rather send that army out to be destroyed by the rebels than leave it sitting there where it makes him nervous. And he has the emperor's ear, and he uses it, and the order comes: attack. Geshu Han reads the order — the third one, the one that leaves no room — and my body, the staff officer at his shoulder, watches a sick old man's hand shake on the paper. And Geshu Han says it to no one, in the flat voice of a man reading his own sentence.

Geshu_han: In the pass we cannot be beaten. He knows that. That is why he wants us out of it. He is not afraid of the rebels. He is afraid of me.

Bram: And the staff officer says the only thing there is to say, which is the loyal thing, and the wrong thing.

The_staff_officer: General. It is under the seal. We have no lawful way to refuse it.

Geshu_han: No. We have not.

Bram: And then, because it is the last order of his life and he will not let a man in the capital own it, he gives it himself, out loud, so the staff around him hear whose it is.

Geshu_han: Sound the advance. And when they ask, afterward, whose order it was — it was mine. Not the chancellor's. Mine.

Bram: And that is the whole of it — that is what obedience costs when it has no limit — and he gives the command, and the army comes down out of the rock it cannot be beaten in, and moves into the open ground where it can. And the rebels are waiting for exactly this. It goes fast. That is the thing nobody tells you about a disaster — the speed. One moment we are a formation, a real army, lamellar and lances and the drums keeping the ranks, and the next there is arrow-fall coming in like weather, a whole sky of it, and the man on the horse three feet to my left makes a sound and looks down and there is an arrow all the way through him, through the small overlapping plates of the armour that was supposed to stop exactly that, and he is still holding the reins and he is already dead, he just has not finished falling yet. And then the cavalry hits the flank. And a formation is a thing made of everybody trusting that the man beside them will hold — and the instant that trust breaks anywhere it breaks everywhere, and there is no army any more, there is just a huge terrified crowd with its back to a river, and the rebels ride into it. I am not going to dress this up. It is not a battle after the first few minutes. It is a killing. Men drown going into the water to get away from the horses. The narrow ground that was our shield becomes the sack we are caught in. The staff officer's whole knowledge of terrain, all of it correct, is worth nothing now, and he knows it, and that is the last thing this body knows. Of the great army that held the pass, a few thousand come out the other side. Geshu Han is taken, and made to send a letter urging other loyal generals to surrender, and later killed by the rebels anyway — a good soldier destroyed not by the enemy but by the frightened man at court who could not bear to leave him alone. The pass is open. The road to the largest city on earth is open. And it happened not because the rebels were unstoppable but because a chancellor was afraid of his own side. Remember that, when you hear later whose fault all this was said to be. Back to Chang'an now, one week later, before dawn — and I have to slow down and be careful here, because what happens next is the hinge of the whole thing, and it happens in a hurry, in the dark, to people who have not slept. The pass has fallen. There is nothing between the rebels and the capital now, and everyone at the top knows it. And so, before first light on the fourteenth of July, the emperor and his consort and the chancellor and a few hundred guards go out through a western gate and run — and they tell nobody. They do not warn the city. The largest city on earth wakes up on an ordinary morning to discover that its government has simply left in the night, and there is no drum, and no order, and no one is coming, and a million people are on their own. And out on the road west, a day later, at a scruffy little post-station called Mawei, that flight is about to stop being a flight and become something much worse — because three hundred of those guards have now not eaten in three days, and they have started to think about whose fault this is. Come and stand in the ranks with them. Put on the armour. This is the one I've been dreading. The Mawei post-station, the fifteenth of July, the middle of a hot afternoon, and the first thing, before anything else, is that I have not eaten in three days and neither has anyone around me. This body is a guardsman of the Longwu — the imperial escort, the men who are supposed to be the most disciplined in the empire — and right now he is one of three hundred identical armoured men standing in a dusty walled yard in the middle of harvest country, in armour that has not come off in two days, drinking irrigation-ditch water out of his own upturned helmet because there is nothing else. Cut wheat in the fields all around, and the ditch-water, and the sweat inside the lamellar — I name the smells first and those are the smells, and under them the specific stink of a lot of frightened men who have not washed. There is a covered cart in the yard with the consort in it. There is the emperor, an old man, somewhere behind the screens. And there is a feeling in the three hundred men that I can feel in my own borrowed chest, and it is turning, slowly, from fear into something with a direction. Because the guardsman knows exactly whose fault this is. Everyone around him knows. It's the chancellor. Yang Guozhong. The man who lost the pass, the man who ran the empire into the ground on his cousin's name, the man who is right now over there arranging to take them all to his province, where he is safe. Three days of no food and one certainty: this is his fault, and he is standing right there. And it happens fast and it happens without anyone quite deciding it. Some of the men see the chancellor talking to a group of foreign envoys by the kitchen, and a shout goes up that he is plotting with the enemy, and then there is no more thinking, there is just movement, and the crowd goes for him, and they cut him down by the post-station kitchen, him and his son, and two of the consort's sisters who are travelling with the court, and suddenly there are bodies on the ground and three hundred armed men have crossed a line that you cannot walk back over. And then they will not march. That is the thing. The chancellor is dead and it is not enough, because the men have understood, in their bones, that they have just murdered the emperor's chief minister, and there is only one way to survive that, which is to make it not a crime — to make it justice — and for it to be justice, the rot has to go all the way up, and they know it can't stop at a man. So the shout changes. And now they are standing in the yard, three hundred of them, my body among them, shouting the same short sentence over and over, my own throat shouting it, and it is not a plea, it is a wall of sound with a demand inside it.

The_guardsmen: While the root remains! While the root remains, we do not march!

Bram: The chancellor was a branch. The root is in the cart. They want the consort. They want Yang Guifei. And I need to be honest with you about what this feels like from inside the ranks, because it is the whole point. It does not feel like madness. It feels correct. Three days without food and a lost capital and a dead chancellor, and every man around you certain, and you are certain too — you can feel the certainty in the body like a fever — that she is the source of it. That the old man up there lost the world because he was besotted with a beautiful woman, and let her family run the state into the fire, and here at last is the moment to make it right. It is three in the morning in the soul of every man in that yard, and at three in the morning that is simply, obviously true. She held no office. She commanded no soldier. She made no policy. And not one man in that yard can hear it, and neither, quite, can I, while I am wearing this body — that is how good the lie is, and that is why it has lasted eleven hundred years. The commander of the escort, an old officer named Chen Xuanli who has served the emperor since before any of these men were born, goes to the screens. And he does not order the men to stand down, because he can't, and he knows he can't. He does the other thing. He carries the demand in — and I can hear it, because the yard has gone quiet to listen — and he presents a mutiny to his emperor as if it were a request, in careful, formal, terrible language.

Chen_xuanli: Majesty. The chancellor has paid for his treason. But the army is not at ease, and it will not move, while the source of the disorder remains among us. I ask Your Majesty to consider the great plan.

Bram: And here is the emperor. Not the doting fool of the story. Watch him. He is seventy years old and he has come to the throne over bodies — he took power in a coup, he has had his own sons killed on a slander, he knows exactly what he is and has spent thirty happy years pretending he doesn't have to be it any more. And now the old ruthlessness comes back, for the last time, and it is the most frightening thing in this whole yard, because it is not weakness. He does the arithmetic. Three hundred armed men, a dead chancellor, an escort that will not move, an heir to protect, a dynasty to save, and one woman. It takes him — I am guessing at the inside of him, but I am guessing from a man who took a throne in a night — it takes him under two minutes. And the horror of it, the thing he will not be able to live with, is not that he is weak. It is that he is strong, and he calculates correctly, and the answer comes out her. And when he speaks, the first thing out of him is not the order. It is the truth, said once, uselessly, to the old eunuch beside him.

Xuanzong: She has done nothing. Everyone in this yard knows she has done nothing.

Bram: And then the order — four words, the sound of a strong man choosing anyway.

Xuanzong: See that it is done.

Bram: And I think — and this is mine, this is the composed part, but I would bet my whole strange life on it — I think she understood before he said it, and did not make him say it. A court woman knows how a court disposes of people; she has watched it; and I think she looked at the yard full of shouting men and the grey old face behind the screen and did the same sum he did, and got there first, and spared him the last few words. And when the old eunuch comes to the cart for her, what she says to him is not a plea either.

Yang_guifei: I know. It is all right. Only — be quick, and do not let him watch.

Bram: There is a small plain chapel by the road, a Buddhist one, with a bell over the door. And the man who takes her there is not a soldier. It is Gao Lishi — the eunuch who has served the emperor for fifty years, his closest attendant, the gentlest and most trusted man in the emperor's whole life. And the emperor asks him to do it, and the reason he asks him — the terrible reason — is precisely that he is the one who will. A man whose family was destroyed and whose whole self was organised, seventy years ago, around a single attachment, will do anything to preserve it, including this. He is not cruel. He is not weak. He is loyal, and this is what loyalty costs when it has no limit. He walks her to the chapel under the bell, and at the door he says the only thing there is, very quietly, and it is not to comfort her, it is because it is true.

Gao_lishi: If it is not me, my lady, it will be one of them, and they will not be kind, and they will make it last. Come inside. Look at the wall, not at me.

Bram: And he does it with a silk cord, and it takes the time that it actually takes, which is longer than you want it to be, and he does not raise his voice, and when it is done she is thirty-seven years old and she is the only person killed at Mawei who had no power, no office and no army — killed because three hundred hungry men needed the catastrophe to have a face, and hers was the one everyone already knew. And then — this is the part I cannot get out of my head — then the men march. That's it. That is what it was for. The cord does its work in the little chapel and the certainty goes out of the yard like air out of a bladder, and three hundred men who could not take another step pick up their spears and form up and go, because the thing that was stopping them is dead. My body among them. He falls in and he marches and he feels, God help him, relief, and somewhere under the relief the first cold edge of the thought he will have for the rest of his life, which is: it was never her. Come off that road with me for a minute. I need to lay out what the war becomes, because it stops being a story about a palace and turns into something much larger and much worse, and I don't want you to lose the thread of it. At Mawei the court splits. The old emperor goes on, south, over a terrifying mountain road into Shu — the region you would call Sichuan — a broken man carried into exile past cliffs, and he is finished; within weeks his own son is proclaimed emperor far to the north, at a place called Lingwu, by an army that needed a ruler who was not running away. So now there are three men calling themselves emperor at once: an old one in the mountains who abandoned his capital, a rebel one sitting in it, and a son crowned on a battlefield because somebody had to be. And the rebels take Chang'an — the city you walked through, the market, the wards — and they loot it, and they kill the members of the imperial family who did not get out. And here is the part that should be a triumph and is instead the darkest joke in the whole war. The rebel emperor, An Lushan — the enormous, watchful, brilliant man — does not enjoy his victory, because by now he is going blind. His eyes are failing, probably from diabetes, and for a man whose entire life was reading rooms, reading faces, that is a specific terror, and it makes him violent, and he beats his servants, and he shuts himself away in the Luoyang palace in agony. And in January 757, his own son, afraid of being passed over, has him murdered in his bed — by his own personal eunuch, a man he had beaten too often, who does it in the dark. He is said to have cried out that the thief was of his own household. The man who took an empire could not hold his own bedchamber for fourteen months. And the rebellion does not even pause. That is the horror of it: killing the man who started it changes nothing. It has become bigger than any person in it. And trapped inside the occupied capital that whole first winter is a middle-aged, failed, minor official who has been trying to reach the new emperor's court and got caught on the road — a man nobody has heard of, who is about to make, out of exactly this, the most famous eight lines in the language. Come and be him. He is the reason we know any of this at all. Chang'an again, in the spring of 757 — the same city, and I promised you that you wouldn't recognise it, and you won't, because the first thing, the thing that stops me in the street, is that it is quiet. You heard this city. You stood in that market and it came off the ground like heat, a million people all being alive at once. Now stand here. There is a wind, and the wind is the loudest thing. The great avenue — a hundred and fifty metres wide, built to move an empire down — has grass growing up it, and weeds, tall ones, because no feet and no cart-wheels have worn them down in months. The ward gates hang open or burned. There are no night-soil carts and there is a smell under everything that I am not going to describe to you except to say that a great many people died here and not all of them have been dealt with. It is the same map with the people subtracted. It is the most terrible thing I have shown you and there is no violence in it at all — the violence has already happened, and this is the quiet after, which is worse. And this body. Oh, this body. He is in his forties, lean, careworn, a plain grey robe gone shabby at the cuffs, the soft black head-wrap of an ordinary man, and hands that will not stay still — that pick up a phrase and turn it over and set it down, testing the weight, while the rest of him does something else. He is called Du Fu. He is a failed examinee — he took the great imperial examination twice and failed it twice, once in a year the chancellor passed nobody — and he has spent twenty years since submitting poems to the palace hoping for a job, and got one, a tiny one, in 755, weeks before the world came apart. He is nobody. He has no money and no post and, at this moment, no way through the rebel lines to the family he moved to safety or the court he was trying to reach. He was caught on the road and he is being held in the occupied city, and he is not important enough for anyone to bother about, which is the only reason he is alive. And he walks through it. That is what he does. He walks through the wreck of the greatest city on earth and he attends — he cannot not — he sees the specific things, the exact things, the ones you would look away from, and he keeps them. A looted house with the door off. The place by the river where the court used to come out in spring, empty now, and the specific memory of a beautiful woman there once, which the whole city is quietly not saying her name about. The imperial clansmen were killed in the palace and the birds have come back before the people have. He counts things — mouths, days, the price of grain, which has gone insane — he cannot stop counting, it is how he holds the horror still enough to look at. And on a spring morning, in a city that has stopped, he sits down and he makes eight lines. And I am going to give them to you, because they are the seed of the whole thing, and because every literate person in that civilisation for the next twelve hundred years is going to know them by heart, and here is the man, in the ruins, making them, with nobody watching and no audience anywhere in his mind. He writes: the state is shattered; the mountains and the rivers remain. Spring in the city; the grass and the trees grow deep. And it goes on — the flowers that make him weep, the birds that startle his heart, the beacon-fires that have burned for three months, a letter from home worth ten thousand in gold, and his own hair going thin and grey and too sparse now to even hold the pin that keeps it up. Look at what that is. The state is shattered — and the mountains and rivers remain. The country is gone and the land it stood on has not even noticed. Everything human is broken and the spring has come exactly as it always comes, indifferent and beautiful, grass in the avenue, and that gap — between the catastrophe and the blossom that does not care about it — is the whole feeling of the eighth century collapsing, held in four…
