Four days had passed since the first great Russian tide had fallen upon East Prussia.
Four days of hell.
Four days since 27 July 1914—Oskar's twenty-sixth birthday—when the Russian masses had come crashing across the frontier like a flood, and the Black Legion had answered them with iron, fire, and extermination.
Now it was the evening of 31 July.
In those four days, the world had changed.
The land between East Prussia and the Vistula had become partially a wasteland. Villages had burned. Roads had blackened. Bridges had fallen. Whole stretches of countryside had been stripped or set alight by the retreating Russians in their scorched-earth panic, as though the Empire would rather ruin the land than let Germany take it whole. Smoke had hung for days above forests and fields. Dead horses, abandoned guns, broken carts, smashed wagons, and bloated bodies had become part of the landscape.
And yet not everything had been destroyed.
That was why the new headquarters stood where it did.
The small town of Ciechanów had been taken quickly enough that much of it still lived. The Russians had stripped it in haste—anything portable and valuable had been dragged away eastward if they had the time. Records, silverware, paintings, cash reserves, official seals, liquor stores, office furnishings, even private valuables from homes and shops had vanished wherever frightened officials or looters had managed to seize them. What remained was the shell of a town: solid walls, empty rooms, a ghost town waiting to be claimed by whoever arrived first with discipline and guns.
And now after the Germans had arrived, the town no longer felt like a town at all.
It felt like a military camp pretending to wear civilian skin.
Soldiers stood at intersections. Motor lorries growled in the square. Messengers splashed through the muddy streets with dispatch satchels under their arms. Patrols moved in twos and fours past shuttered shopfronts and darkened homes. Field kitchens smoked behind municipal buildings. Ammunition crates were stacked under awnings. Telephone wires had been run where decorative flags and civic lamps might once have hung. The local stables were now army stables. The schoolhouses quartered troops. The larger homes held officers. Barns and warehouses had become supply depots.
At the center of it all stood the town hall.
Solid, red-brick, old-fashioned, and proud in the provincial way, it still dominated the square. Its façade remained intact. Its clock tower still rose over the streets. Its tall windows still held the memory of petitions, tax disputes, weddings, and civic dinners. But that memory had been driven out.
Now guards stood at every entrance.
Staff cars waited below.
Couriers climbed the front steps at a run.
Behind those tall windows, lamplight no longer shone upon clerks of the town and respectable burghers of peace. It shone on maps, casualty ledgers, artillery reports, radio logs, railway lines, and information regarding the near-utter destruction of the Russian 2nd Army.
That army no longer existed in any meaningful sense.
It had been shattered, encircled, and torn apart. What remained of it had dissolved into fleeing fragments hiding in woods, marshes, and ruined villages. There were still shots in the distance, still small pockets of resistance, still cleanup columns hunting men tree by tree and ditch by ditch—but the battle itself was over.
The result was no longer in doubt.
The First Russian Army had fared little better. Bloodied by artillery, strafed by aircraft, checked by rivers and prepared defenses, it had lost the initiative and been thrown back to lick its wounds. Along the southern arc, the Black Legion had pushed out of East Prussia and down toward the Vistula, where sniper teams, artillery, and aircraft now harassed the remnants of Russian forces on the other side of the river.
As for Oskar, for the first time in four days the need for him to fight personally in the front line had diminished.
Not because the war was finished.
But because the killing had become systematic.
So he had finally stopped.
For a few hours.
He had been bathed, groomed, and cared for by his two personal assistants, Patricia and Elise, who had made a brief journey to headquarters now that the roads were secure enough for it. He had slept, if only for a little while, in an actual bed. When he woke, he was dressed once more like a prince. His hair had been washed. His face shaved. Clean linen. Clean boots. A fresh military uniform cut to fit a ruler and a butcher both.
On the surface, he looked untouched.
As if he had not ridden men down for four straight days.
As if he had not split and crushed bodies in such numbers that his own mind no longer wished to count them.
Shadowmane had been stripped of his barding and taken to the stables behind the square. There too, men worked in hushed caution. The stallion was being washed, brushed, fed, treated, and watched. His wounds had been cleaned. His armor was being repaired. But even at rest, half-dozing over feed and warm water, he did not look tame. He looked like a beast merely pausing between slaughters.
Oskar had visited him after dressing.
Shadowmane had turned one dark eye toward him, snorted once in greeting, and lowered his head again.
For Oskar, that had been enough.
He had smiled faintly, patted the horse once, and walked away.
Now he moved through the town hall in his fresh uniform as though the last four days had not bent him at all.
His posture was straight.
His face was calm.
His steps were measured.
No limp. No stiffness. No weakness.
To anyone who passed him, he looked as he always did—large, composed, broad-shouldered, pale-haired, and unshaken. A prince carved from iron and given flesh.
Only inside was the strain visible.
And only to himself.
Because while his body had recovered with unnatural speed, his mind had not been granted the same mercy. As he walked, flashes still came unbidden—brief, knife-sharp fragments of battle. A Russian running and then suddenly no longer whole. A horse screaming with its guts out. Trees bursting under shellfire. Bone giving beneath a downward stroke. And worst of all, his own men dead in the mud, sometimes whole, sometimes not.
He felt no thrill in it.
No savage pride.
No intoxication of conquest.
Only the conviction that war was a tragedy, and that he would nonetheless do what he believed necessary until peace was brought into the world by force and on his terms.
He walked on.
The corridors of the town hall had been stripped nearly bare. Whatever art, silver, books, or luxuries the Russians had managed to seize, they had taken with them. What remained was mostly structure: walls, floors, doors, old civic furniture too heavy or too worthless to carry. And even that had been rearranged for war.
Maps were pinned to walls.
Tables had been dragged into hallways.
Telephones sat in rows.
Radio sets crackled in former committee rooms.
Clerks moved quickly with files and signal slips.
Mud had been tracked across tiled floors and polished boards alike.
A handful of German women brought from the rear now moved quietly through the building, cleaning where they could, keeping the officers' quarters orderly, trying to impose hygiene and normality on a structure that had become a military machine.
But there was one thing missing.
Smoke.
Or nearly missing.
In another headquarters—another Germany, another age—the rooms would have been thick with cigarette smoke, stale alcohol, and the cough of exhausted officers bent over their maps. But Oskar's reforms had prevented that world from ever taking root. Smoking had been made expensive, unfashionable, and quietly discouraged before it had the chance to become a habit of the nation. What might once have grown into a universal vice among men had instead been strangled early. In this Germany it survived only as a small, private indulgence practiced by a few and nothing more.
So here there were only traces.
A faint curl from one corner.
A crushed stub somewhere discreetly hidden.
Nothing more.
So instead the air smelled of wet wool, ink, leather, machine oil, coffee, and tired men eating sandwiches sent up from the army kitchens.
Oskar preferred it that way.
Outside the tall windows, the last light of evening was dying over the small town of Ciechanów. He moved quietly through the corridors toward the double doors standing open ahead of him. Warm yellow light spilled through them.
The meeting room.
The former council chamber had become the nerve center of the southern headquarters. Even before he reached the doorway, he could hear the room breathing: low, controlled voices, the scrape of a chair leg, the dull tap of a finger or pointer against a map. Men who had survived four days of hell and had already begun planning the next four.
Inside waited the men who now carried the war with him.
At the far side of the great central map table stood General Paul von Hindenburg, deputy commander of the Black Legion and Oskar's great reserve of authority—vast, solid, and still as some old Prussian monument dragged down from its pedestal and forced back into service. Heavy-jawed, broad-faced, immovable through the shoulders, with that enormous walrus moustache and the unreadable calm of a man too old and too seasoned to waste emotion where it served no purpose.
Beside him stood Major General Erich Ludendorff, chief of staff and the operational brain of the army. If Hindenburg was stone, Ludendorff was drawn wire—leaner, sharper, sleepless-eyed, restless even when standing still, the sort of man whose mind never stopped calculating where the enemy would crack next.
Near the southern side of the map was General Hermann von François, commander of I Corps, thick-set and hard-faced, one gloved hand braced against the table edge. Mud still marked one sleeve. With his heavy moustache and scarred attack-dog look, he seemed a man who belonged beside a gun line more naturally than beneath a chandelier.
A little apart from him stood General August von Mackensen, commander of XVII Corps. Tall, aristocratic, and severe, with the proud bearing of an older cavalry age, he seemed almost too elegant for the room—until one noticed how campaign dirt and fatigue had weathered that elegance into something sharp and dangerous.
Colder than the others was General Hans von Seeckt, commander of XX Corps. Slighter in build, refined where François was blunt and cerebral where Hindenburg was monumental, he looked less like a battlefield icon than a mind given rank and uniform—a man built to turn chaos into geometry and victory into timetable.
And then there was Lieutenant General Erwin Rommel, commander of the 1st Armored Division.
Young—shockingly young beside the rest. Lean, compact, sharp-faced, with the contained stillness of a man who knew he had entered rooms meant for older men and intended to prove, day after day, that he belonged in them more than most. Among the old Prussian beasts of command, he looked like the future standing quietly in field-grey.
Staff officers moved around them—clerks, aides, operations men, signal officers, exhausted captains with dispatch cases and notebooks—but those six were the true center of gravity. Around them, the room itself seemed to bend.
It had once been beautiful.
High-ceilinged. Dark wood-paneled. Tall windows half-draped against the night. Civic paintings still hanging where they had not been displaced by maps. Brass lamps and electric fixtures casting warm light over polished tables now scarred by compasses, coffee rings, and mud-stained gloves.
One wall had disappeared behind a vast map of the eastern theater, layered with colored pins, grease-pencil marks, strings, and annotations. Another table held telephones, signal logs, coded dispatches, rulers, pistols, and half-drunk cups of coffee gone cold long ago.
The room still possessed the bones of peace.
War had merely grown inside it.
For a moment, no one spoke.
They saw him standing in the doorway—not in black armor, not in the skull-helm, not fresh from the saddle with Russian blood drying on his gauntlets, but washed, composed, pale-haired, broad-shouldered, terrible in a quieter way.
A prince again.
And yet not.
Oskar stepped across the threshold.
The floorboards gave a low groan beneath his weight.
Every eye in the room turned fully toward him.
And over the maps of the Vistula, Warsaw, and the broken Russian retreat, the next phase of the war waited.
Then Hindenburg broke the silence.
"Your Highness—congratulations."
He lifted his glass, and the others followed at once. Oskar did not refuse them this time. He raised his own glass with them, though where the others had wine, his held only apple juice.
Hindenburg's heavy face had actually softened with satisfaction.
"Thanks to your inventions, and to the transformation of the old Eighth Army into the Black Legion, this victory has not merely been great—it has been decisive. The sort of victory that will be told and retold in history books for generations. And thanks to your war correspondents, much of it has already been captured on film. Naturally, the more gruesome parts will be removed. Only the heroic images will remain. We shall show the world Germany at its best."
Ludendorff nodded sharply.
"Indeed. The men's morale could scarcely be higher. The Russian Second Army is finished in all but name, and if they try to reinforce it, they will only feed more men into ruin. Warsaw will be ours next month, if not sooner. Our losses, though real, are light compared to theirs. A few thousand against devastation on a scale they will not soon recover from."
François joined in, his voice carrying the rough certainty of a man who had seen the front with his own eyes.
"And this was only the opening phase of the eastern war. More than that—I will say this plainly, Your Highness: had you not personally led the right flank, I do not believe we would be standing in such a position now. The men know it as well. Trust me when I say this—they are yours until death. There is no man in the world, alive or dead, whom they would rather follow."
Oskar inclined his head and accepted the praise without false embarrassment.
Yet he felt no real satisfaction.
Not truly.
He had seen too much over the last four days for that.
Soon larger battles would come. More armies. More fronts. More dead. The heaps of Russian bodies he had already seen were vast enough that a smaller nation might have broken from them forever. For Russia, they were only the beginning.
"You praise me too highly," Oskar said at last, his voice calm and measured. "I appreciate it, but I could not have done any of it without you, without the staff, without the officers, and without the soldiers who fought and died to make this possible. This victory was not mine alone. It was won by all of us."
He raised his glass slightly.
"So let us drink not only to victory—but to the men, and above all to the glorious dead who made the ultimate sacrifice to bring us this far."
That, too, was pure Oskar.
Even now, even after four days of industrial slaughter, he spoke as he always had. To him, Germany was like a body. Each organ, each limb, each nerve had its place and purpose. No part could claim the work of the whole.
But Ludendorff shook his head.
"Your Highness, you are too modest."
His tone was sincere, not flattering.
"If not for you, how could the Black Legion have been remade so quickly? How could it have been armed with weapons and systems no other army in Europe possesses? The men did their duty, yes. So did we. But without you there would be no such army, no such victory, and no such war plan."
The others clearly agreed.
Oskar smiled faintly, but said nothing more.
He knew what he had done.
Not only for the army, but for the state itself.
His work ran through every artery of the Empire.
And if Germany won this war, it would be because he had spent years remaking the Empire into something capable of winning it.
The High Seas Fleet alone was no longer what it had once been in that other timeline. It had been transformed. Its gunnery, doctrine, ship design, and readiness had all been dragged forward by force. Behind it stood a submarine arm far stronger than before, and beyond that, two aircraft carriers still in heavy training yet already nearing combat readiness. When the decisive naval struggle came—and Oskar had no doubt it would come—those ships and all the changes behind them would matter. None of it had appeared by accident. It had been built, pushed, paid for, and forced into being by him, and by Karl beside him.
Of course, he knew this war was still far from over.
But Warsaw was close.
And with Warsaw would come not merely a battlefield victory, but a wound cut deep into the Russian Empire itself. So far, he had not managed to prevent the war. That failure still stood. Yet he had already done something else: he had torn Germany away from the destiny that had once awaited it. He had changed not only his own fate, nor only that of the Hohenzollerns, but the fate of the Empire as a whole.
Thinking of that, Oskar felt no real pride.
Only relief.
Relief that Germany had not entered this war blind, weak, and unready.
After a moment, he asked, "How many casualties have we suffered on the Eastern Front so far?"
Germany had over seventy million people, yes. By European standards it was a great population.
To Oskar, it still felt too small.
Every trained German soldier was precious.
Ludendorff answered at once.
"As previously reported, Your Highness, a little over two thousand dead so far. Many of them fell during the night fighting, which was difficult to avoid. Had it not been for the shock effect of the 1st Armored Division and the work of the air arm, our losses would almost certainly have been far worse—perhaps double."
Oskar nodded once, but the number still sat heavily in his mind. Two thousand. Small by the standards of what this war might yet become. Enormous by the standard of any man who had to write to the mothers, wives, and fathers of the dead.
"If not for the reforms," Ludendorff continued, "the butcher's bill would have been much higher."
"I know," Oskar said quietly.
Then he looked at the men around the table.
"The fallen must be properly compensated. The wounded must receive the best treatment we can give them. Those who recover and return will be among our finest veterans and should be honored accordingly. And those who do not return to service—the crippled, the maimed, the permanently broken—we will not discard."
His voice remained calm, but there was iron beneath it.
"We will see that they live," Oskar said. "Properly. With dignity. With pride. Let the people see that the men who bleed for Germany are not discarded once they can no longer carry a rifle. They are not numbers in a ledger. They are not expendable tools. They are human beings, and their lives have value."
"Yes, Your Highness," Hindenburg said at once.
"It will be done," Ludendorff added.
The men around the table understood exactly what he meant.
Most of them were noble-born, wealthy enough that they themselves had never had to fear poverty, debt, or social ruin. But they were soldiers too, and none of them were fools. They knew what became of ordinary men broken by war. A ruined leg, a missing arm, shattered lungs, damaged nerves—such wounds did not end when the guns fell silent. They poisoned the whole rest of a man's life, and often the lives of his family as well.
For the Crown Prince himself to think of such matters—not as sentiment, not as display, but as policy—was not something they took lightly.
It strengthened something that had been growing inside them for years.
Not merely respect.
Loyalty.
Once, many of them had looked at Oskar with doubt. He had been too young, too strange, too ambitious, too willing to tear apart old systems and replace them with things no prudent Prussian officer was supposed to trust. They had obeyed him because the chain of command required it. But obedience was one thing.
Faith was another.
Then came the reforms.
The rebuilding of the Black Legion.
The radios.
The guns.
The new artillery doctrine.
The motorized columns.
The tanks.
The air arm.
The training, the discipline, the logistics, the endless flow of new equipment that actually arrived when promised.
What had seemed reckless fantasy at first had, piece by piece, become reality in their hands. And then reality had become victory.
That won their professional trust.
But Oskar himself won something deeper.
Because he did not merely understand weapons or organization or the movement of armies on maps.
He understood what armies were made of.
Men.
German men.
And he cared what became of them.
That, more than all the tanks and aircraft and new doctrines, had fixed their devotion in place.
By now, if the Emperor himself and Oskar had issued opposite orders, all of the men in this room would have followed Oskar without hesitation.
Not from rebellion.
From belief.
Oskar let the silence settle for a moment, then turned back to the map.
"My men, my generals hear me," he said, "the battle against the Second Russian Army has been effectively won. And while small numbers have escaped, it hardly matters. They are no longer capable of threatening the campaign in any serious way. Our next objective is clear."
His hand moved north-east, then curved south.
"The Seventeenth Corps must remain in place and continue holding the First Russian Army at bay. That is their task."
He tapped the map again, this time at the Vistula crossings and Warsaw beyond.
"The rest of the army will continue to move south. In three days, we must cross the Vistula in force and take Warsaw and its surrounding districts. Before the Russians can restore their second army or move in another army to reinforce it."
The officers around the table leaned in slightly.
Oskar's voice remained even, but the scale of what he was proposing was plain enough. This was no longer merely a defensive victory in East Prussia. This was the beginning of a drive into the heart of Russian Poland.
Ludendorff nodded first.
"That is the correct course," he said. "If the Seventeenth Corps holds the First Army in place, then it will be fixed there. It cannot easily disengage and move south in time. Meanwhile, the main weight of our forces can be turned against Warsaw before the Russians fully recover."
François grunted his approval.
"They've been hit too hard and too fast. If we move now, we'll catch them before they remember how to breathe."
Mackensen's gloved finger traced one of the rail lines.
"And if Warsaw falls quickly, the whole theater changes. Politically as much as militarily."
Seeckt gave a small nod.
"It will also force the Russians to choose. Either they attempt to save the city and weaken their remaining fronts further, or they abandon it and lose more than just Poland. They will have to pull back their armies from the Galician front against Austria-Hungary, or else they would face encirclement with our Black Legion falling upon their backs from the north."
Rommel, who had been silent until then, finally spoke.
"There is only one concern," he said. "The armored division."
Every eye in the room shifted toward him.
Rommel spoke without hesitation.
"The fighting has cost us tanks—more than I would have liked," he said calmly. "Very few to enemy fire. Most were lost to the march itself. We pushed the machines too hard—long distances, broken roads, continuous operations."
He paused briefly, then added with the same dry tone:
"And there was the matter of that wooden bridge."
A few of the officers glanced up.
"Three tanks crossed it at once. The bridge disagreed."
A faint murmur passed through the room.
Rommel continued, unbothered.
"So yes—mechanical attrition has taken its toll. Nearly as much as battle."
That drew no surprise from Oskar.
It was the cost of forcing the future into the present.
Ludendorff took up the explanation.
"The armored division entered the campaign with over one hundred and fifty tanks. By the time of the decisive fighting, operational numbers had already fallen by nearly a fifth because of breakdowns, track wear, engine strain, and transmission failures. After the battle, the number of immediately combat-ready vehicles was reduced sharply again."
He glanced toward Oskar.
"If we intend to use them for the Warsaw advance, they must be replenished."
Oskar did not so much as blink.
"Then replenish them."
Rommel looked at him.
Oskar rested one hand on the edge of the table.
"Imperial Weapons Works has already dispatched replacement vehicles ahead of schedule," he said. "So do not worry, a fresh batch is already en route. I have directed the trains to the town of Soldau, from where they will move south to our assembly area here. The armored division will be re-equipped here at Ciechanów."
That drew a flicker of satisfaction from more than one face in the room.
Rommel allowed himself the slightest hint of a smile.
"Then the problem is solved."
"It was never going to remain unsolved," Oskar said.
That, too, was part of why their loyalty to him had become so absolute.
He did not merely demand results.
He anticipated needs before others had fully voiced them.
Karl and Imperial Weapons Works had turned that habit into iron, engines, and guns, and now the army reaped the reward.
Ludendorff straightened.
"In that case, the movement orders can go out tonight. The Seventeenth Corps holds the First Russian Army in place. The remainder of the Black Legion shifts south, crosses the Vistula by boats in the night, then we build pontoon bridges, and begin the advance on Warsaw."
Oskar nodded once.
"Yes."
His eyes lowered to the map again.
The next major blow against Russia awaited at Warsaw.
