第9章 The Ash Road

The column moved at the pace of its slowest man. Corvinus had learned the rule as a junior officer in the Fourth, and he had watched better commanders pay in blood for breaking it. An army that outran its wounded was a rumor of an army, and the road north from Petra ran under six feet of ash in the hollows and less where the wind had scoured through to the old stone. Two hundred and seventy souls marched out of the ash that first morning. Ten more were buried where the mountain had put them, and the column did not count them twice, because the dead do not keep pace with the living. He put himself at the rear of the column, where the worst of the dust was, because a man who would set the pace had to be the one eating it. Cassius moved beside him with the garrison ledger wrapped in oiled cloth, counting mouths and reckoning rations in the same low mutter he had used over amphorae in the storehouse. The water was rationed by the horn at the morning halt, drawn from the skins they had filled at the deep spring before the passage was closed. The wounded rode the litters made from cloaks and spear shafts, and the carrying detail rotated on the hour so that no man carried the dead weight of a friend past the limit of his own strength. The first order of the march was simple. No one walked ahead of the column. No one fell behind without word. Corvinus planted sentries in the ash desert as if it were frontier country ringed with enemies, and the men grumbled because grumbling was the army's oldest music, and they did as they were told. It was, Maro said later, the first time in three years that Petra's garrison had been marched anywhere at a speed that did not resemble the retreat of a man who owed money. They found the landslide before noon. The road north had already been cut once, in the days before the eruption, and the mountain had added a second and then a third coat of rubble and ash on top of the old scar. The men cleared it by hand, in relays, passing stones down the slope and shoveling the loose ash aside with the flats of their shields and their hands. The ash ran like water back into the cut faster than they could throw it, and the work crawled. Corvinus took his turn in the line, and Maro directed from the top of the spoil, and after an hour the stubborn Greek trick of banking the spoil downstream of the cut turned a losing fight into a slow, grinding win. By dusk the column was moving again through a notch the mountain had not planned to give them. The family was waiting on the far side of the cut, huddled under a cart frame with the wheels gone. A woman and two children and a farmer from the eastern slopes who had walked three days through the ash to find the road. The woman was alive and the children were alive and the farmer had a broken leg set badly, and the column, which was starved and blistered and nine miles from any place a man could lie down in safety, stood in the road and did what Petra had taught them. It made room. Livia walked the length of the column that first night, and Corvinus walked with her as far as the perimeter. The camp was fireless except for the one low flame they fed with fence rails and chair legs carried out of the town's ruin, ringed around with the children and the women who were near to birth. The mountain stood above them, a black shape against a sky that was no longer orange, and the ash fell thin and constant, like the first snow of a winter that did not mean to end. "It is quiet," Livia said. "Quieter than it has been in my lifetime. That is not rest. A man who holds his breath is not resting. He is waiting to see if he is heard." "The seal held." "The first mouth was stopped," she said. "The mountain does not have only one mouth." She said it without drama, the way she had said the water would turn, and Corvinus felt the cold of it settle behind his ribs. "The god does not end his speech with a single word, Tribune. He is old, and he is patient, and he was not finished." They slept in the ash that night, and the morning brought the coast. The ground changed beneath them as the third day climbed: ash thinning to scuffed grey, then the first blades of grass standing out of the spoil, then the dark soil of the coastal plain, and finally, at the noon halt, the sea itself, grey and flat and enormous at the edge of the world. The column quickened without a word being given, a hundred small paces shortening, and Corvinus slowed them with a raised hand, because an army is fastest when it believes it has arrived, and that was how armies died at the gates of cities they had marched three weeks to take. The junction where the mountain road met the coast road was held by a stockade of field stones and palisade posts, and a banner hung from a pole that Corvinus did not know, and men in armor he did not know stood behind the barricade with their spears grounded in the Roman manner. A centurion of the governor's household rode out to meet them, tablet in hand, and read the writ without looking at the column behind Corvinus. No person of the mountain district was to pass to the coast without written authority. The garrison was to encamp outside the stockade and await the clerk of arrivals. Weapons were to be stacked in the compound under guard, and the remuster list was to be handed over by nightfall. The centurion finished reading and finally looked up. He was a thick man with a scar on his jaw that Corvinus had seen before, on a different road, years ago. The recognition crossed the man's face at the same time it crossed Corvinus's own. "Corvinus," the centurion said. "The tribune. From the coast road." "From Petra," Corvinus said. "These people are the survivors of the evacuation. They are not smugglers and they are not deserters. They walked out of the mountain in good order, and they will be recorded as such." The centurion looked past him at the grey, walking dead of the column. Maro's silence had weight. The children were silent because they had been taught silence. The silence of two hundred and seventy people who had outlived their world was a thing that could be heard across water. "I have my orders," the centurion said. "Weapons are stacked. The list comes by nightfall. And the young woman everyone is calling the priestess—" He consulted the tablet, and the scar on his jaw moved when he chewed the word. "—Livia. She is to be brought to the clerk's office in the morning, armed or not. By name. By order of the governor." Corvinus looked past the stockade, past the banner, to the picket line behind the palisade, where the horses stood in the wind off the sea. Among them, tied with a double hitch he would have known anywhere, stood a roan with a white foreleg. He had last seen that horse saddled and ready outside the centurion's quarters in Catania, a week before the mountain spoke. "By order of the governor," Corvinus repeated. His voice was flat. He had practiced it flat in a courtroom in Rome, and it had not failed him in the years since. "Vorenus is inside the stockade." The centurion said nothing, which was an answer. The column encamped in the ash stubble outside the gate. The weapons were stacked in the compound under guard, and the remuster list went to the clerk by nightfall, written in Cassius's careful hand. And Corvinus stood at the edge of the firelight with Livia's silence at his shoulder and Maro's, and the mountain at his back, and understood that the road out of Petra had been a road into a different kind of cage, and that Vorenus, who had been the lawful voice of the garrison, was on the other side of a palisade waiting for him. The sea was grey before them. The mountain was grey behind them. And somewhere between the two, the law of the district had closed like a door he had not seen built.
