#On the River Position
"Where the cliffs lean close enough to be chained."
The sappers of the first garrisons found two places in the Iron Gates where the black basalt pressed in close enough for a boom to be strung from cliff to cliff on no more than eighty yards of forged links. They called the places Gate One and Gate Two. Chain Gate Two is the second, and this entry concerns it alone. The eighty yards is an upper limit taken from the survey of the whole gorge. Nobody has published what Gate Two's chain measures, and I have not asked, because the answer would be a number and the question would become a file.
Below the chain the Danube runs deep and fast, the colour of wet slate. On either side the cliffs climb some three hundred feet of iron-seamed stone that rings when a hammer strikes it, and cannon batteries are cut into both faces. A hull coming down the gorge meets iron at the waterline and guns overhead. That arithmetic was settled when the first battery was cut and nobody has needed to revise it since.
Gate Two has no walls of its own. It belongs to Bastion-Irongate, fifth of the seven bastions of the Sagittal Line, with Bastion-Sibiu to the north and Bastion-Shipka to the south. The Line runs north and south, and the river crosses it here. In this gorge the Line becomes a throat, and Gate Two is one of the two places where the Synod has closed its hand on that throat. The Codex records no distance between the two gates and does not say which one a barge meets first. A reader who wants a diagram of locks and basins may apply to the Bureau of Engineering, which will not supply one.
#On the Gallery Above the Chain
"Halfway between plainsong and artillery."
There is an observation gallery above Gate Two. It is the one part of this position the Codex can describe from personal experience, so the Codex will describe it.
I stood there once, at dusk. The wind had turned easterly and was coming up the gorge against the current. It passed through the sixty-three tunnel mouths bored into the southern cliff face, and the cliff sang. I first felt it through the soles of my boots, then in the wet rail under my gloves, and last in my teeth. I have written elsewhere that the sound was halfway between plainsong and artillery. I have been told since that this is impossible. I heard it anyway, and I still have.
The sixty-three mouths belong to the whole southern face, not to Gate Two. The gallery simply happens to be a good place to stand when they sound. From there the chain sags into the river haze, the batteries are dark shapes on the stone, and the cliff opposite is pierced along its length like a choir-stall carved by a craftsman who never stopped working. The Bureau of Bells classifies the effect as a Category Three Harmonic Anomaly: too beautiful to be natural, too useful to be investigated. The Bureau has sent three commissions anyway. The first came back with a report. The second came back with a hymn. The third did not come back.
What a man hears from the gallery is only the outside of the instrument. The inside is the Transit Spine, the main bore that runs the length of the southern cliff, together with the great chambers that branch from it. One of those chambers is the Choir Nave, where the chant crews assemble for their shifts. They sing in rotating eight-hour watches, and their hymns are calibrated to the seals of each chamber. Channels cut through the rock carry the chant to every gasket in the complex. At dusk the wind is the mountain's contribution. The crews are the Synod's.
The gallery plays no part in that system. Nobody sings stanzas there and nobody reads pressure gauges there. It is a place for looking and, at the right hour, for listening. Anyone who reports otherwise is describing the Nave and has lost his way in the dark.
Nobody at the Irongate trusts a quiet evening. The Great Hush of A.S. 94 began when an atmospheric inversion silenced the tunnel mouths for nine hours. The pressure doors failed one after another, the Third Lung collapsed, and three thousand men were entered in the register of the dead. The rescue crews needed eleven months to dig them out. A man in the gallery on a windless dusk hears the river and the creak of the chain, and he waits for the chant to come through the rock. He does not leave until it has gone round the stanza again.
The Bureau of Engineering once described the Irongate's chant system as "supplementary to conventional bracing."
That description has been withdrawn, as recorded in the parent entry. The iron ribbing carries about thirty-one percent of the load and the chant carries the remaining sixty-nine. These figures apply to the tunnels. Readers who have applied them to the boom below the gallery must withdraw that reading as well. No assessment on file says that Gate Two's chain has to be sung.
#On Passage and Authority
"The smallest piece of brass in the Irongate, and the heaviest."
Gate Two has no commandant and no staff on file, and the Codex records no tariff or timetable for it. The bastion governs the position the same way it governs everything in the gorge, from inside the mountain and on paper.
Commandant Hadrik Sorn commands the garrison. He also controls the Transit Spine, the pressure doors, and the charges set along the main bore for compartmental denial. The batteries above the chain are garrison batteries. Their orders come down through the rock from a man whose sense of humour his superiors have described as absent.
Cantor Ys Varr presides over voice licensing for the Choir Magistracy. A gunner on the cliff above Gate Two is a gunner while he is on watch. When he goes off watch he is a throat with a tier, and his tier decides whether he sleeps warm. About twenty-two thousand souls live in Bastion-Irongate, and every one of them is subject to the same auditions, held under the same pressure gauge.
Seal-Broker Lysa Murne runs the permit desk of the Breath Office. Gate passes, convoy manifests and quarantine clearances all cross her desk, including those for the convoys between Sibiu and Shipka that swell the gorge in surge seasons. The chain decides whether a hull passes. Her seal decides whether a man does. The chain cannot be bribed and cannot be persuaded. Her seal is quicker.
The Codex does not print the inspection order, the hours of the watch, or how many men stand above the river at any moment. The garrison knows them, and so, presumably, does the enemy, who would prefer to learn them from us.
#On Recognition and Defense
"Her replacement arrived an hour early, wearing his face."
Morwen, the Weeping Host and Sin-General of Envy, holds the Danube approaches opposite the Irongate. The chain was forged against fleets, and Morwen does not send fleets. She sends people the garrison already knows. A sapper's partner begins to speak in another man's cadence: the phrases are correct and the intonation is wrong, as though the words had been learned from a transcript rather than lived. A sentry reports that his relief came an hour early, wearing his face.
In a fortress kept standing by voices, an enemy who steals voices has chosen her ground with care. I remember standing in the gallery while the southern cliff sang. Afterwards I lay awake wondering how many of the voices in the Nave that evening belonged to the men who had signed for them.
The Bureau of Purity responds with Mirror Discipline, adopted in A.S. 193 after the Incident at Sector Nineteen. That incident happened inside the mountain, not at the river, and its disposition remains sealed. Under the Discipline no soldier may look at his own reflection for more than three seconds. At dusk the Danube below Gate Two gives back the cliffs, the dark mouths and the underside of the gallery. I looked down, counted to three and looked away. I am vain, not reckless.
The Ledgers of Self record every man stationed in the mountain: his scars, his habits, his confessed sins, the way he holds his mess-tin. The Ledger is definitive. It is also a document, and when two claimants recite it equally well, the document has nothing more to tell the magistrate. The garrison's answer is the Twinning, which executes both claimants. The Bureau of War calls it efficient. The chaplains call it deeply regretted. A boom of forged iron cannot stop a lieutenant whose papers are correct, whose scar sits above the right eyebrow and who knows the name of the right dog. The Twinning does stop him, along with the man he replaced.
#On the Recorded Condition
"If the echo answers, don't answer back."
The Codex holds no construction record for Gate Two. The chain and the gallery have no recorded year of hanging, cutting or ratification. The dates that exist belong to the bastion. Its permanent garrison went onto the southern cliff in A.S. 67, the northern cliff was garrisoned six months later, and the bastion was ratified in A.S. 72. The engineers of those years worked for the Church and its provisional authorities a generation before the formal Synod of A.S. 90. The Bureau of Engineering's claim to them is retrospective, and the Bureau has never been shy about claiming things after the fact. The only survey plate in the Codex shows Gate One. Gate Two has been left to my memory, which I consider the better archive.
The Bureau of Doctrine's assessment of the Irongate, sealed in A.S. 201, gives the bastion's status as ENDURES. Gate Two endures with it. The chain is up and the batteries are manned. Somewhere behind the southern face a crew is singing the third watch, and on an easterly evening the sixty-three mouths will answer them whether the Bureau of Bells has sent anyone to listen or not.
