#On Its Use Before Fire
The Litany of Correct Arc is the prayer Gun-Cantor Marshal Vonn recites before each salvo from the casemates of Bastion-Brest. That is its whole public definition, and I will not inflate it for the comfort of archivists. The record gives the Litany no composer, no adopting council, no ratification year, and no authorized text. What it gives is use: a commander with a brass plate at his throat, a loaded gun in a riveted gallery over the Bug, and words spoken before the powder is allowed to speak.
Brest is a bridge-fortress of brass ribs and wet decking in the northern Bug sector of the Line. Every crossing there is confessed, stamped and watched from the casemates. Vonn holds the casemate fire keys, the curfew bells, the safety salvos and the discipline of the artillery choir. The Litany belongs to the last of these. It answers to the first.
This tract surveys the practice as it stands under his command in A.S. 201. I leave its origin where I found it, unrecorded.
#On Recitation and Range
Brest command describes the procedure as a sequence of voices. Vonn recites the Litany. Cantor-Lieutenant Sera sings the range tables. These are separate offices, and anyone who has stood in a casemate during loading will keep them separate. The prayer belongs to the Marshal and the numbers belong to the Lieutenant. No account I have received puts the range tables inside the Litany's words, and I will not put them there to tidy the liturgy.
Sera's voice carries distance as pitch. The crews mark fuse and elevation against what they hear, hands on cold screws, sleeves black to the elbow, the gallery smelling of gun oil, wet iron and the river that never quite stays outside. The casemate bells answer with iron clappers, and the answer passes from rib to rib through the brass. Powder receives a thumb-mark of ash. Shells go to the breech under numbers alone, never under personal names, because junior gunners grow fond of anything they carry and a shell is carried only so that it can leave. Then the guns discharge in chorus.
Gun-Cantors are trained to bind range, powder, bell and psalm into a single firing discipline. Outsiders hear a choir that happens to be standing near cannon. The crews hear an order of work. I have seen the inside of enough chapels and enough batteries to say that the difference is smaller than either the Bureau of Bells or the Bureau of War would like.
What I will not supply is a refrain, a stanza count, or a score for Sera's tables. Brest has not released them, and I have not invented them. A clerk who prints a gunnery hymn from imagination deserves to hear it sung back at him with live elevations.
#On Prayer and Accuracy
The Bureau of War reports that Vonn's prayers have never improved his accuracy. I accept the measurement. Bureau surveyors can count impacts, pace craters and divide one column by another as well as any clerk in the Synod's employ. Their mistake is the assumption behind the survey.
Vonn does not pray to aim better, because he already aims well. He prays because of where the arc ends. A gun on the Brass Ribs points along a deck where people queue with candles and papers, and the man who sets its elevation knows the trajectory before the shell does. If he troubles the Creator with that knowledge before the gun troubles the crowd, the practice is accountancy of the soul. Bureau ballistic tables have no column for it.
The procedure's practical value is also easy to see. One voice settles the gallery, another carries the numbers, and iron answers for crews who cannot see the commander. Men who drill to the same sequence every time make fewer of the small errors that put powder where hands are. That is a reasonable account of the coordination. It remains unmeasured, and I claim no timing gain the Bureau has not recorded. I claim no miracle either. The shells fall where good gunnery sends them, and so far the Creator has not been asked to correct the elevation.
A War Bureau training note describes Vonn's pre-salvo rite as "morale theatre."
Corrected under Brest objection, as entered in the Marshal's dossier. Theatre requires an audience. The gunners take part in the rite, witness it and share in what follows.
#On the Arc Across the Bridge
Brest's defence doctrine is interlocking casemate fire and kill zones along the deck. The phrase reads cleanly in a manual. On the bridge it means that a correctly calculated arc can come down on a lane of the queued, a convoy, a widow carrying the wrong token, or a crowd that has begun to run because the bells rang in an unfamiliar order. A correct arc tells you the angle was right. It tells you nothing about whether the target was.
The Litany authorizes none of that. It is no crossing writ, no tribunal judgment and no sacramental license to fire. Those powers are kept elsewhere, by people who distrust one another for good reason. Judge Elsbeth Krail and the Bridge Tribunal judge crossings. Seal-Registrar Hett Ruis holds the stamps and identity corrections. Vonn holds the guns. A rite spoken in one of those three houses becomes, inevitably, part of how the bridge is governed. Every civilian on the deck knows the sequence of bells that comes before a safety salvo, even if they will never hear the words of the Litany.
The street's fear has a name: the "accidental" shot on the deck. Vonn's crews would rather frighten a crowd than bury it, and his warning fire has been the subject of complaint, ridicule and grudging relief. The prayer does not make that power gentle. It keeps the man who holds the power from pretending it is gentle.
#On Voices Near Loaded Guns
The Confession Echo makes every vocal rite on Brest a matter of risk. Sins spoken into the booths come back later as whispers from shutters, vents, wet plating and rope. Candle flames bend toward the booths, and mist under the ribs gathers into shapes the provosts are told not to call faces. Men already full of fear have panicked, confessed again, and on occasion climbed the rail.
A gun gallery holds powder, iron, tired men and a commander reciting aloud. Vonn ordered casemate crews to stop confessing in the lanes closest to loaded galleries. Tribunal routing objected and Doctrine's equal-access policy objected. Both published command accounts report that misfires then fell by half. I record that figure as Brest reports it. It does not prove that the Litany guards against the Echo or that the Echo answers to the Litany. It shows only that Vonn took the confessing voices away from his powder, and the powder behaved better afterwards.
Booth 77 repeats confessions before they are spoken. No source says it has ever recited the Litany or given a firing command, and I mention it only because of what it means for a firing discipline. A procedure carried by voices relies on knowing which voice is speaking. Vonn has asked to burn the booth and fire the residue east. Doctrine advised observation.
East is where the Nameless Tide gathers against the wire. It does not respond to hymns. It does not respond to relics. Since the A.S. 200 eastern wire incident, when a patrol found the forward stakes bowed inward with no alarm sounded, Vonn has suspected a relationship between the Tide and the Grey at Königsberg. The two share a suppression tier and are classified as distinct, and the suspicion is his alone. The Litany is said before the guns fire on that approach. No one at Brest claims the Tide hears it.
#On Its Present Employment
As of A.S. 201, the Litany of Correct Arc is recited before each salvo from Brest's casemates, as long as Vonn holds command. Sera sings the tables. The bells answer. Ash marks the powder, numbers mark the shells, and the guns fire in chorus over a bridge whose booths sometimes repeat sins nobody has confessed yet. The Bureau of War has found no gain in accuracy. Brest command has recorded a drop in misfires once the confessing voices were moved away from the powder. The record holds no words and no origin, and it shows no effect of the Litany on anything that lives east of the wire.
