How Prussia Learned to Fight, 1757–1870

What the Drums No Longer Said

Frederick II, Scharnhorst, Moltke, the Duke of Brunswick, MacMahon, Wimpffen, and Napoleon III are historical figures, and the battles here follow the documented record as closely as fiction allows. Martin Lenz, Ludwig von Arnstett, Georg Bartel, and Reinhold Achterberg never existed. This time the through-line is not a family but an idea — how a Prussian army was ordered to fight, and how, four times across a century, that answer had to be entirely relearned. A note on sources sits at the end.


I. The King's Gamble

Parchwitz and Leuthen, Silesia — 3–5 December 1757

At Parchwitz, three days before the battle, King Frederick II of Prussia gathered his generals into a room and told them, in words that no two men who heard them would afterward remember quite the same way, that he intended to attack an Austrian army very nearly twice the size of his own, in open defiance of every accepted rule of war, and that any officer who did not feel equal to the risk could resign his commission on the spot without reproach. He said, or was remembered to have said, that he would answer for the outcome with his own life; that a battle won would restore Silesia and the war both; that a battle lost left nothing further to discuss.

He did not tell them, because a king does not, that he had spent much of that autumn closer to the edge of his own composure than any account written for public consumption would ever admit. Breslau had fallen to the Austrians three weeks before. His army, thinned by a summer of hard marching and a defeat at Breslau's gates, numbered barely thirty-six thousand against Prince Charles of Lorraine's sixty-odd thousand dug in along a low ridge above the village of Leuthen. He was thirty-five years old, had been at war with one coalition or another for most of his adult reign, and understood — better than any general in the room, because he alone carried the whole calculation of it — that a second Silesia lost this year, on top of Kolin in June, might be a Prussia lost for good. He had learned, in the years since his own father had forced him at seventeen to watch a friend's execution rather than let him escape into desertion together, to keep whatever this cost him entirely off his face. It was, by that December, less a discipline than a second skin.

Two miles off and three days later, in the dark before the march began, a Musketier of one of the Silesian-raised companies named Martin Lenz stood in the ranks with no more idea of what the King intended than the horse in front of him, and considerably more reason than most of the men beside him to feel two ways about the coming day at once. Lenz had been a subject of the Austrian Empress until he was fourteen, when Frederick's first invasion of Silesia in 1740 redrew the ground under his family's feet without asking anyone's leave, and the King's canton officers had registered him for the army the same year his new sovereign's soldiers first marched through his village. He had worn the Prussian coat for six years now, well enough that his sergeant no longer needled him about his accent, but he was about to spend this particular morning killing men who might, under a different throw of dynastic dice, have been recruited from the farm two fields over from the one he'd grown up on. He kept this thought, like the King kept his despair, entirely off his face.

The march that carried him there began at four in the morning in a column that moved without drums, screened behind a low chain of hills — the Schleierberg, the Sophienberg — that hid the army's whole intention from the Austrian pickets who could see, and were meant to see, only a cavalry detachment left drifting near Frobelwitz as a decoy. Lenz understood none of the design. He understood the cold, and the particular strain of marching for hours at a pace nobody would explain, and the moment, past eight, when the column bent left as one body and he grasped — the way a man grasps a joke a half-second late — that they had spent the whole morning walking clean around the enemy's flank in order to come at its weakest end from a direction it had never thought to guard.

The King, riding with the leading division, had staked the entire war on that half-second's realization occurring to sixty thousand Austrians a great deal too late.

It did. The assault went into the village of Sagschütz on the Austrian left with the bayonet and almost no volley fire at all — the theory, drilled into every battalion for two decades now, being that a line which does not stop to reload does not stop — and the Württemberg and Croatian troops holding the place broke before most of the steel arrived. Lenz's own company came up in support through smoke already thickening over ground it could not see ten paces into, and for the two hours that followed his entire war narrowed to the back of the man ahead of him, the tear of a cartridge paper between his teeth, the flat kick of the musket, and the discipline — cut two years before from four ranks to three, so that a Prussian line could put more muskets into a volley than an Austrian line the same length — that let his hands go on loading long after his mind had stopped following any of it as a story with a shape.

By early afternoon the fighting had reached the second Austrian position along the rise where the windmill at Leuthen stood, and the close, ugly work of clearing the village itself cost his company more men than the whole morning had. Snow began falling through the smoke sometime after three — Lenz would remember, decades on, the strangeness of a field littered with the dead going quietly white, as though the sky had simply declined to notice what was happening under it — and by full dark the Austrian army no longer existed as a fighting force, six thousand Prussian casualties against something near twenty-two thousand Austrian, twelve thousand of those taken prisoner outright.

He found a place that night in the ruined church at Leuthen, packed with wounded of both armies brought in out of the cold because it was the only roof left with any repair to it, and it is there, in the retelling that would run through the following century and beyond, that the grenadiers of the army are supposed to have begun singing the old chorale Nun danket alle Gott until the sound carried the length of the field in the dark and the snow. Whether that happened exactly as it would be told, or whether a handful of men sang badly to themselves and forty thousand grateful voices were built onto it afterward by a nation that needed the story, Lenz never much troubled himself to settle. He heard two men near him take it up, off-key and out of time with each other, and did not, that night, feel much like singing anything himself.

The King rode the field the next morning in the manner every account of him from this period agrees on: dismounting nowhere in particular, speaking to no soldier by name, already turning the next three moves of the war over in a mind that had, by long practice, stopped expecting to be understood by the men it commanded and had long since stopped much wanting to be. He had gambled the kingdom on one morning's march and won it. He would spend the next six years of war learning, at considerable further cost, that the trick did not repeat itself indefinitely merely because it had once worked so completely.


Interlude: The Drill Becomes a Creed

By the time Frederick died in 1786, the oblique order that had been, at Leuthen, an audacious improvisation forced on him by a desperate arithmetic of numbers had calcified, in the hands of the generation that inherited his army, into something closer to scripture. The King himself, in his last years, had begun to sense the danger of it — a note to a nephew wondered aloud what would become of an army that mistook a dead king's genius for a set of instructions any competent colonel could follow by rote — but armies, like courts, tend to preserve exactly the parts of a great man's example that require the least of his successors' actual judgment.

A young grenadier named Ludwig von Arnstett had stood, at nineteen, on the field at Kunersdorf in August of 1759, two years after Leuthen, on the single worst day of Frederick's military life — a battle so completely lost that the King, watching his army break apart around him under Russian and Austrian guns, was heard by more than one officer that evening to speak of ending his own life rather than carry the news of it home, and had to be argued out of the field by men junior enough that recounting the conversation afterward cost several of them their composure for years. Arnstett had helped carry a wounded major off that ground and had seen, at close range, a king's face with the mask entirely gone from it for perhaps the only time in four decades of public life. He never told the story often. When he did, in his own old age, it was always to make the same point: that the King's genius had never been the absence of catastrophe, only the discipline of appearing, the next morning, as though catastrophe were simply one more variable already priced in.

Arnstett carried that lesson into a colonelcy of his own, and carried with it, less usefully, an unexamined faith that the specific tactics of 1757 — the three ranks, the oblique march, the bayonet advance without firing — were themselves the substance of the lesson rather than one generation's particular answer to one particular arithmetic of ground and numbers. He was not a stupid man. He was, like a great many capable officers of his generation, a man who had been given no reason by anyone above him to ask whether the answer needed updating, in an army and a court that had spent thirty years treating Frederick's methods as a kind of natural law rather than a set of choices made by one mortal king against one particular set of enemies on one particular winter morning.


II. The Doctrine Breaks

Auerstedt — 14 October 1806

Oberst Ludwig von Arnstett was sixty-six years old on the morning the Duke of Brunswick led the main Prussian army west out of its camp near Auerstedt into a fog thick enough to lose a column in, and he rode that morning with the specific, settled confidence of a man who had spent forty-seven years certain he already understood the one thing about war that mattered. His regiment drilled, in the autumn of 1806, almost exactly as it had drilled in 1780 — three ranks, the same manual of arms, the same trust that a disciplined line, once formed, was itself close to an unanswerable argument. He had grown old inside an army that had not, in any tactical particular that mattered, changed since the year of his colonelcy, and had taken the absence of change for a kind of proof.

What came out of the fog against him that morning was Marshal Davout's III Corps, twenty-six thousand Frenchmen already deployed along the high ground above the Lissbach stream, fighting in a manner Arnstett's whole career had given him no vocabulary to describe: not the ordered, rolling volley-fire of his own youth but something faster, denser, more willing to break formation and reform it under fire than any doctrine he had ever drilled a man in permitted. The Duke of Brunswick, seventy-one and riding forward to see the position for himself, was struck in the face and blinded within the first hours of the fight, carried from the field a dying man; the King, left in nominal command of a battle whose full shape no one had shown him, believed for some part of that morning that he faced Napoleon in person rather than one of his marshals doing extraordinarily well without him, and husbanded reserves against a blow that had, in every sense that counted, already landed.

Arnstett's own regiment was fed into that collapsing morning in the manner his whole career had trained him to trust: formed, dressed, advanced by the manual, and cut apart by French fire delivered with a flexibility his three ranks had no answer for at all. He did not break. He held his line exactly as long as a line so instructed could be held, watched it come apart anyway by early afternoon, and rode off the field past four that afternoon among wagons abandoned in the ditches and men who had stopped, entirely, believing in anything the morning had told them to believe. Fifteen thousand Prussian dead and wounded lay behind the retreat, three thousand more taken prisoner, fifty-seven guns lost, against a French bill of a little over seven thousand — a single corps, outnumbered nearly two to one on paper, having beaten an army that still, that morning, believed itself the possessor of Frederick's unrepeatable trick.

Arnstett lived another eleven years, long enough to watch a Hanoverian officer of no great family named Gerhard von Scharnhorst walk the wreckage of the old army with a commission's authority to rebuild it from the ground, and long enough to sit, twice, examinations for continued rank alongside men half his age whose fathers had been merchants rather than colonels, and to lose those examinations on points of terrain reading and combined-arms doctrine that his own forty years of parade-ground certainty had simply never required him to learn. He said, near the end of his life, to a young relation about to take a commission of his own, that he had spent his whole career believing he understood Frederick's war, and had discovered too late that what he had actually understood was Frederick's tactics — which were not, whatever his generation had assumed, the same thing at all.


Interlude: The Mission and the Needle

Scharnhorst's commission built, out of the wreckage Arnstett's generation had left behind, an answer aimed less at any single battlefield trick than at the problem the trick had always concealed: that an army whose subordinate officers could not be trusted to think would always, eventually, meet an enemy whose subordinate officers could. The reforms that followed over the next decade — a General Staff trained as one professional body rather than a scatter of well-born amateurs, promotion increasingly by examination rather than birth, the abolition of the old brutal disciplinary code, and, threaded through all of it, a doctrine that would come to be called Auftragstaktik — asked something of a Prussian officer that Frederick's army had never asked and Frederick's temperament, by every account, would have found close to unbearable: that a commander state his intent and largely leave the method to the man on the ground, trusting that the man who could see the actual terrain would usually decide faster and better than the man reading a map two miles behind him.

Alongside it, more quietly, came a weapon that would not be tested in earnest for another two decades: a breech-loading rifle developed by a gunsmith named Johann Nikolaus von Dreyse, adopted by the Prussian army in 1841, that let an infantryman reload lying flat on his stomach behind whatever cover the ground offered rather than standing exposed to ram a charge down a muzzle. It fired perhaps six aimed rounds in the time an Austrian musket, still loaded from the front, managed one or two. Nobody in Berlin in 1841 could have said with any confidence what that difference would mean once it met, on open ground, an enemy who had not troubled to make the same change. In July of 1866, outside a Bohemian town called Königgrätz, the whole army found out together.


III. The Rate of Fire

Königgrätz — 3 July 1866

Unteroffizier Georg Bartel lay on his stomach in the wet ground at the edge of the Swiepwald a little before eight in the morning, working the bolt of his needle rifle with hands that had, over four hours of fighting, stopped needing his eyes to guide them, and understood, in the specific and uncomplicated way a soldier understands the thing directly in front of him rather than the shape of the whole day, that the war he had trained for and the war he was actually fighting were not, in one crucial particular, the same war his own father had described from 1815.

The Austrians came at the wood in the close, dense columns their own doctrine still prized — a doctrine built, like Arnstett's had been sixty years before, on the conviction that resolve and cold steel would settle what rifles could not, that a determined bayonet charge closed the distance before firepower had time to matter. It had been true enough in an age of muzzle-loaders, when a defending line got one shot and then a long, exposed silence in which to reload standing upright under fire. It was no longer true. Bartel and the men on either side of him put round after round into the advancing columns from cover, reloading without ever rising off the ground, and watched entire companies of brave men be cut down before they came within bayonet range of anything at all. The wood changed hands more than once that morning regardless — courage counted for something even against arithmetic this lopsided, and the fighting in among the trees was close and desperate enough that Bartel lost, by mid-morning, two men he'd trained alongside for three years — but the exchange rate of the thing was not, by any measure either army could later agree on, remotely even.

For most of that same morning, word running back down the lines made it plain that the battle further south might be lost entirely before the Crown Prince's Second Army — delayed since dawn by an order that had itself been slow to reach it — arrived to matter at all. Prussian headquarters, a few miles to the rear, is said to have spent those hours with a composure that struck more than one officer on the staff as faintly inhuman: Field Marshal Moltke, the quiet Chief of the General Staff who had built the doctrine Bartel was, without ever using the word for it, currently practising on his stomach in the mud, had staked the entire risk of the day on subordinates whose judgment and timing he could not personally supervise, and appeared to have decided, having built the system, that there was nothing further useful for him to do but trust it.

It was rewarded a little after one in the afternoon, when the leading elements of the Guard Corps came up unexpectedly against the village of Chlum — the hinge of the whole Austrian position, thinly held — and took it without waiting for permission from anyone further back than their own colonel's judgment of the ground in front of him. By three the battle was, without any single dramatic reversal, simply over. Bartel came out of the Swiepwald that evening with powder burns on his hands and a private, unheroic understanding that would take the rest of the army rather longer to fully absorb: that a rifle a man could reload without standing up had just quietly finished the tactical argument Frederick's bayonet advance had settled, on different terms, a hundred and nine years before.


IV. The Gun That Sees Farther

Sedan — 1 September 1870

Leutnant Reinhold Achterberg stood beside his battery on the high ground above the village of Bazeilles a little before five in the morning, watching the last of the river fog lift off the Meuse, and had under his hand a weapon that made the entire argument Bartel had settled with a rifle look, by comparison, almost quaint. His guns were cast steel, breech-loaded, rifled — built at Krupp's works in Essen and carried to this ground by a rail network laid out with the same patient thoroughness Scharnhorst's staff had once brought to reorganising an officer corps — and they reached ground the French guns opposite, still bronze, still loaded from the muzzle, simply could not answer. For most of that long day his crews would fire at targets they could see clearly and be fired back at, at worst, ineffectively.

Below him, Bavarian troops had begun crossing the Meuse on pontoon bridges an hour before dawn, moving into Bazeilles while the French Marine garrison there still slept through the last of the fog, and by nine that morning the encirclement Moltke's staff had designed with the same patient trust in subordinate timing that had won Chlum four years before — Saxons and the Guard across the river to the east, Bavarians pressing from the south, two further corps closing from the north — had drawn itself entirely shut around Marshal MacMahon's Army of Châlons, more than a hundred thousand Frenchmen with the Emperor Napoleon III among them, trapped in a bend of the river under guns sited on every height around it. MacMahon had been wounded by a shell splinter a little after six; the command that passed to General Ducrot at seven was taken from him again within the hour by General Wimpffen waving an old ministerial letter naming him successor, a piece of administrative confusion that meant no single French officer held real authority long enough, for the whole of that morning, to use it.

Achterberg's crews had time, in the long gaps between corrections his own tradition would once have called idleness and his instructors now called opportunity to rest and feed the men — because even here, even now, a gunner's blistered hands and empty stomach did not stop mattering just because history had chosen the field he stood on — to watch the smoke over Bazeilles thicken from rifle-smoke into something heavier, a village actually burning, and to hear, distantly, the specific close and ugly sound of house-to-house fighting that no rifled steel gun on a hilltop could do anything to soften from this distance.

The worst of the day, for him, came past two in the afternoon at a village called Floing on the western edge of the closing ring, where General Margueritte led the last intact French cavalry — cuirassiers and chasseurs in bright coats that belonged, visibly, to an older and slower war than the one being fought around them — in a charge meant to blow a gap through the Prussian line before the trap finished closing. Margueritte went down mortally wounded in the very first charge, before it had even reached the infantry it was aimed at, and the two further charges pressed home after him by men who could by then see plainly enough what the ground ahead held were not so much attacks as an argument conducted entirely in the bodies of horses and riders against a fact that breech-loading rifles had already settled, the same fact Bartel's needle gun had settled at Königgrätz four years before, now delivered at a scale and a range the Austrians had never had to answer. Nearly eight hundred French cavalrymen were down or scattered within the hour. Achterberg watched it through a field glass with an unwilling, cold-throated respect he did not examine too closely at the time, and did not order his own guns to add to it once the range closed past any use; there seemed, by then, no further argument left for the guns to make.

A white flag went up over the citadel wall at Sedan itself sometime after four that afternoon, the particular white that every soldier on that height, in whichever coat, understood without needing it explained. Wimpffen asked that evening for terms he could call honourable; Moltke, from his own headquarters, declined to soften what the guns had already decided, and the surrender was signed the following morning a little past eleven. A little over a hundred thousand French soldiers went into captivity, the Emperor among them, riding out under guard toward a small château to wait for whatever the men who had beaten him chose to do with an empire once its army had ceased, in any practical sense, to exist.

Achterberg wrote home that week that the guns had done most of what needed doing before the infantry were much called upon at all, and did not, in the letter, dwell on what he privately understood well enough: that the argument settled at Sedan had begun, in its essentials, on a foggy morning near Leuthen a hundred and thirteen years before, in the mind of a king who had never once, in any of the intervening iterations, been asked whether he wanted the answer carried this far.


Coda

In January of the following year, in the Hall of Mirrors at Versailles, King Wilhelm of Prussia was proclaimed German Emperor, and the four ideas this account has followed — a king's desperate oblique march, a doctrine of trusted subordinate judgment born out of one army's total collapse, a rifle that let a man reload without standing up, and a gun of cast steel that could kill at a range its target could not answer — had between them built the dominant military power of the European continent, entirely without needing any one of the men who had carried them to still be present to take credit. Bartel was by then a Feldwebel training recruits on a rifle already being quietly superseded by something better. Achterberg's guns went on to other wars he did not live to see the ends of. The King who had gambled at Parchwitz had been dead for eighty-four years, and the tactics he had staked his kingdom on that December morning had been proven wrong, refined, discarded, and replaced three separate times by men who never once stopped invoking his name while doing it.

None of the four men in this account would have called that progress, exactly, if anyone had troubled to ask them. It was simply what the century had required of the idea, each time the previous answer met an enemy who had also been paying attention.


A Note on the History

Martin Lenz, Ludwig von Arnstett, Georg Bartel, and Reinhold Achterberg are invented. Frederick II, the Duke of Brunswick, Davout, Scharnhorst, Moltke, MacMahon, Ducrot, Wimpffen, Margueritte, Napoleon III, and Wilhelm I are historical figures, and the battles are set down as closely to the documented record as fiction allows.

Leuthen was fought 5 December 1757 near the village of Lutynia (then Leuthen), Poland, roughly 10 km northwest of Wrocław. The oblique march behind the Schleierberg and Sophienberg hillocks to strike the Austrian left near Sagschütz, the fighting through Leuthen village, the snowfall as the battle closed, and the casualty figures used here (around 6,300 Prussian, roughly 22,000 Austrian including some 12,000 captured) are all in the standard record. Frederick's Parchwitz address of 3 December is genuinely documented as an event, but no verbatim transcript survives that historians agree on — the version given here is a compressed, invented rendering in that same uncertain tradition, not a claimed quotation. The story of grenadiers singing Nun danket alle Gott that night is treated here, as most modern historians treat it, as beloved tradition rather than verified fact. Frederick's despair at Kunersdorf in August 1759, including his reported talk of suicide on the field, is documented by his contemporaries and by later biographers, though the precise words are, again, not preserved verbatim.

Auerstedt was fought the same day as Jena, 14 October 1806, near the Thuringian village of that name. Marshal Davout's single corps of roughly 26,000 did defeat a main Prussian force half again its size in dense morning fog; the Duke of Brunswick was mortally wounded early in the fighting, and Prussian losses are usually given at around 15,000 killed and wounded, 3,000 prisoners, and 57 guns.

Königgrätz (Sadowa) was fought 3 July 1866 near Hradec Králové in Bohemia. The Dreyse needle gun's roughly sixfold rate-of-fire advantage over the Austrian Lorenz muzzle-loader, the heavy Austrian losses from bayonet-charge tactics pressed against it in the Swiepwald, the delayed Second Army, and the Guard Corps' capture of Chlum a little after one in the afternoon as the battle's turning point are all part of the documented record.

Sedan was fought 1 September 1870, surrender signed the following morning. The Bavarian dawn crossing at Bazeilles, MacMahon's wounding and the Ducrot–Wimpffen confusion, the completed encirclement by roughly nine that morning, Krupp's steel breech-loading artillery's decisive range advantage over French bronze guns, General Margueritte's mortal wounding in the first cavalry charge at Floing, and the casualty and capture figures follow the standard accounts. Wilhelm I's proclamation as German Emperor at Versailles followed on 18 January 1871.
