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, and in those four days the world had changed.
Much of the land between East Prussia and the Vistula had become a wasteland. Villages had burned, roads had blackened and bridges had fallen. Whole stretches of countryside had been stripped or deliberately destroyed by the retreating Russians in their scorched-earth panic, as though the Empire would sooner ruin the land than allow Germany to take it intact. Smoke had hung for days above forests and fields, while dead horses, abandoned guns, shattered wagons and swollen bodies had become as much a part of the landscape as hedgerows and trees.
Yet not everything had been destroyed.
That was why the Black Legion's new headquarters stood where it did.
Ciechanów had fallen quickly enough that most of the town still remained standing. The Russians had stripped it in their haste to retreat, carrying east whatever could be removed and seemed worth taking. Records, silverware, paintings, cash reserves, official seals, liquor, furniture and private valuables had vanished wherever frightened officials, soldiers or looters had found the time to seize them. What they left behind was the shell of a functioning town: solid walls, empty rooms and intact streets waiting to be claimed by whoever arrived next with sufficient discipline and guns.
Once the Germans came, however, Ciechanów ceased to feel like a town at all. It became a military camp wearing civilian skin.
Soldiers guarded intersections while motor lorries growled across the square. Messengers hurried through muddy streets with dispatch satchels under their arms, patrols passed shuttered shops and abandoned homes, and field kitchens smoked behind municipal buildings. Ammunition crates were stacked beneath awnings. Telephone wires crossed streets where civic decorations had once hung. Stables belonged to the army now, schoolhouses quartered troops, larger homes sheltered officers, and barns and warehouses had become depots filled with fuel, food and ammunition.
At the centre of everything stood the town hall.
It was a solid red-brick building, old-fashioned and proud in the provincial manner, still dominating the town square beneath its clock tower. Its façade had survived intact, and its tall windows retained something of the world they had once looked upon: petitions, tax disputes, weddings, council meetings and civic dinners.
That world was gone.
Guards now stood at every entrance. Staff cars waited beneath the steps, couriers hurried through the doors, and behind the tall windows lamplight no longer fell upon clerks and respectable burghers. It illuminated maps, casualty ledgers, artillery reports, radio logs, railway schedules and the accumulating evidence of the near-total destruction of the Russian Second Army.
In every meaningful sense, that army no longer existed.
It had been broken, encircled and torn apart. What remained had dissolved into scattered groups hiding among woods, marshes and ruined villages. There were still occasional shots in the distance, still pockets of resistance and columns combing the countryside for fugitives, but the battle itself was finished. Nothing that happened now could alter its outcome.
The First Russian Army had fared little better. Hammered by artillery, strafed from the air and checked by rivers and prepared defensive positions, it had lost the initiative and been forced back to recover. Along the southern arc, meanwhile, the Black Legion had driven out of East Prussia and toward the Vistula, where artillery, aircraft and sniper teams were already harassing Russian forces across the river.
For the first time in four days, there seemed to be no immediate need for Oskar himself to remain at the front. And so, while his men continued their work in the field, he finally allowed himself what he had denied both body and mind since the fighting began: a few hours of genuine rest.
Shadowmane was resting as well.
To Oskar's considerable surprise, Patricia and Elise had made the journey forward from Königsberg as soon as the roads were judged secure enough, leaving the children safely behind. Officially they had come as his personal attendants. In practice, both women had arrived with the determined air of people who had already decided that their prince was going to be cleaned, fed, comforted and put to bed whether he cooperated or not.
They began by bathing him.
Four days of sweat, grime and blood were washed from his body with considerably more care than any ordinary maids would ever have dared show. Patricia and Elise worked over him patiently, cleaning every trace of the battlefield from his skin, tending the few places that required attention and gradually coaxing the tension from muscles that had scarcely relaxed since the Russians crossed the frontier. Their care soon became far more intimate than simple washing, affection mingling naturally with duty as kisses, embraces and the warmth of familiar bodies helped quiet a mind that soap and hot water alone could not reach.
By the time they were satisfied—and he considerably more relaxed—both women practically forced him into an actual bed.
Even then sleep did not come easily. Oskar had spent too long surrounded by artillery, engines, screaming horses, burning countryside and dead men. His body understood that the room was safe; some part of his mind had not yet accepted it.
Patricia and Elise remained beside him until it did.
Between their warmth, their softness, their familiar scents and their stubborn refusal to let him rise again, the tension gradually drained from him. Eventually his breathing slowed, his enormous body relaxed between them, and for the first time in days Oskar truly slept. It was an almost startling luxury.
And when he woke, the women had already seen to everything else.
His battle-stained clothing had been washed or replaced. His hair was cleaned and combed back, his face shaved smooth, and fresh linen replaced everything that still carried the smell of smoke or blood. Clean boots followed, then a fresh Black Legion uniform: severe, dark and sharply tailored, combining the dignity expected of a Crown Prince with the unmistakable austerity of the army he commanded.
By the time Patricia and Elise were finished with him, Oskar looked almost untouched.
As though he had not spent the previous four days riding through battle drenched in the blood and filth of men he had killed. As though he had not taken so many lives that even his own mind had stopped trying to count them.
Shadowmane, too, had finally been allowed to rest. The great black stallion had been stripped of his barding and taken to the stables behind the square, where sisters of the Church of the New Dawn worked around him with careful familiarity. A priest with exceptional medical skill supervised the treatment of his wounds while grooms washed him, brushed him and brought fresh feed and water. His armour had been taken away for temporary repairs, although both horse and rider would eventually require Oskar's own attention; he had made their armour himself, and no ordinary army workshop truly understood its construction.
Even standing quietly over his feed, Shadowmane did not look tame. He looked like some enormous creature of war merely pausing between battles.
Oskar had visited him after dressing. The stallion turned one dark eye toward him, gave a low snort of recognition and lowered his head again.
That was enough.
As payment for four days of faithful service, Oskar had ordered enough carrots and apples brought in to make the stablemaster stare at him, along with several mares to provide considerably more agreeable company than soldiers, priests and mechanics.
The thought had earned the faintest smile from him. He had patted Shadowmane once before leaving the stable and returning to headquarters.
Now he moved through the town hall in his fresh uniform as though the past four days had failed to bend him at all. His posture remained straight, his stride measured and his face composed. There was no limp, no visible stiffness and no sign of physical weakness. His armour had absorbed nearly everything capable of seriously injuring him.
To the soldiers and staff who stepped aside as he passed, Oskar looked exactly as he always did: enormous, broad-shouldered, pale-haired and unnervingly calm.
A prince carved from iron and somehow given flesh.
Only Oskar knew how tired he truly was.
The slaughter had brought him no pleasure. There was no thrill in killing, no intoxication in conquest and no private delight hidden behind the skull mask. If anything, the last four days had reinforced what he had always believed: war was a tragedy, perhaps the greatest tragedy human beings repeatedly chose to inflict upon themselves.
That belief did not make him hesitate.
He would continue doing what he considered necessary until the war ended, and if peace could only be forced upon Europe through overwhelming violence, then he intended to impose it upon his own terms.
Oskar walked on.
The Russians had stripped the town hall of almost everything worth carrying, leaving behind little more than heavy furniture, bare walls and the building itself. The Germans had wasted no time filling that emptiness with war.
Maps covered the corridors. Telephones occupied former offices, radios crackled behind open doors, and tables had been dragged wherever staff officers needed them. Men and women worked side by side as clerks, signal staff and administrators, carrying reports and coded messages between departments, while women in maid uniforms cleaned muddy floors, changed linen and kept the officers' quarters in order. The headquarters was busy without feeling chaotic, an improvised military machine already settling into its rhythm.
What struck Oskar most was what the building did not smell of.
Smoke.
In another Germany, headquarters such as this might have been buried beneath cigarette haze and stale tobacco. Oskar's years of taxes, restrictions and relentless discouragement had prevented smoking from becoming the universal military habit it might otherwise have been. A few men still indulged privately, but here there were only occasional traces.
Instead the corridors smelled of wet wool, polished leather, ink, machine oil, coffee and hot food from the army kitchens.
Oskar preferred it that way.
Outside the tall windows, the last evening light was fading over Ciechanów. Electric lamps were beginning to glow around the square below as staff cars and lorries moved through the gathering darkness.
Near the end of the corridor, Oskar came upon a pair of heavy double doors standing slightly ajar. Warm yellow light spilled through the gap, accompanied by subdued voices and, unexpectedly, laughter.
He pushed them open.
The conversation stopped almost at once.
Around the great round strategic table stood the six senior commanders who had carried the eastern campaign with him. All wore the severe black dress of the Black Legion: dark tunics, polished leather, the traditional shoulder boards and collar insignia of the Imperial German Army marking their individual ranks, while their peaked caps bore the Legion's unmistakable golden eagle-and-death's-head badge.
Hindenburg and Ludendorff stood near the head of the table. François of I Corps occupied one side, Seeckt of XVII Corps the other, while Mackensen of XX Corps and the much younger Rommel of the 1st Armoured Division stood nearer the southern portion of the enormous operational map.
Dispatches, grease-pencil markings and coloured counters covered nearly every available space.
Yet for once, nobody seemed particularly interested in them.
There were bottles on the table instead.
One champagne bottle already stood open among the glasses. Ludendorff had another braced between his hands and was wrestling with the cork when he glanced toward the doorway.
His entire expression changed.
"Your Highness!"
Hindenburg turned as well, and the old general's usually grave face broke into a broad smile.
"Ah! Just in time."
The others immediately straightened.
For a moment Oskar simply stood there, his enormous frame nearly filling the doorway. Freshly bathed, shaved and dressed, with his pale hair combed neatly back and his black uniform immaculate, he looked almost absurdly untouched by the four days of slaughter behind him.
Then the room erupted.
"Our Iron Prince!"
"The hero of East Prussia!"
"Hear, hear!"
The cork finally surrendered beneath Ludendorff's assault and shot toward the ceiling with a sharp pop. Champagne foamed over his hand as François laughed, Mackensen grinned and even Hindenburg joined in.
Oskar stared at them with genuine surprise.
These were men he normally knew as granite-faced professionals who discussed corps movements, ammunition expenditure and casualty returns with all the emotion of accountants balancing ledgers.
Tonight they were grinning like schoolboys.
"You have arrived at precisely the right moment," Hindenburg announced. "We have decided that, for perhaps half an hour, the Russian Army may continue collapsing without our personal supervision."
The corner of Oskar's mouth twitched.
"I see."
Movement at the edge of the room caught his attention.
Patricia and Elise had apparently been waiting for him. Both wore the neat maid uniforms they used while attending him, though among the six men gathered around the table there was little real mystery left about their place in Oskar's private household. Their unmistakably British accents, imperfect German and Patricia's rather recognizable face had made secrecy difficult long ago.
No one spoke of it.
What precisely existed between Oskar and the two women was understood to be private, and these men had neither the desire nor the disloyalty to turn it into gossip. If the Iron Prince wished a former British princess and her petite blonde companion at his side, then that was his affair—and the matter would remain inside rooms such as this one.
Elise approached with a tray of pastries while Patricia carried a heavy square-cut crystal decanter filled, rather incongruously, with apple juice. Behind the table waited an enormous reinforced chair prepared specifically for Oskar.
He crossed the room, towering over both the table and everyone gathered around it.
Patricia poured his drink. As she leaned closer, a loose strand of hair slipped across her face, and Oskar brushed it aside almost without thinking. A faint blush touched her cheeks. Elise placed the pastries beside him, and Oskar thanked both women with the same quiet familiarity before they withdrew together toward the wall.
The generals noticed.
None reacted.
It was simply another confidence entrusted to them.
The floorboards creaked beneath Oskar as he lifted the comparatively delicate glass into one hand and turned back toward his commanders.
Hindenburg raised his own.
"Well then, Your Highness—allow us to say it properly. Congratulations."
The others immediately followed.
Oskar did not refuse them this time. He raised his apple juice while champagne and wine glittered in the surrounding glasses.
Hindenburg's heavy face had softened with unmistakable satisfaction.
"What has happened these past four days will be studied long after all of us are dead. Thanks to your inventions, your reforms, and the transformation of the old Eighth Army into the Black Legion, this has not merely been a great victory. It has been decisive."
His gaze moved briefly toward the map.
"The Russian Second Army has been destroyed as an effective field army. Their air forces over this theatre have been broken. The First Army remains pinned farther east. Four days ago we were still inside East Prussia preparing for what many expected to become a desperate defensive campaign."
His smile widened.
"Now we stand upon the Vistula with Warsaw almost before us."
Ludendorff nodded sharply.
"What remains of the Second Army is being finished off as we speak. If Russia attempts to rebuild it immediately, they will merely feed fresh formations into a front that has already collapsed."
He lifted his glass slightly.
"Give us time to refuel, repair and reorganise, and Warsaw—and perhaps much more of Poland beyond it—becomes a matter of preparation rather than possibility."
François joined in, his voice carrying the rough certainty of a man who had seen much of the fighting with his own eyes.
"Their command structure is in ruins as well. Reports indicate that several senior Russian officers have been killed, lost or cut off during the retreat. That young pilot, Manfred von Richthofen, apparently followed the retreating Russian's from Soldau far enough to locate their headquarters and bomb it before they could properly organise the withdrawal."
He glanced toward the shrinking red pockets on the map.
"The results rather support his account. Much of the Second Army remained trapped north of the river and is being destroyed now. South of the Vistula, what remains of it appears to number fewer than fifty thousand effective men, though fresh conscripts continue arriving."
A few approving murmurs followed.
Then François looked directly at Oskar.
"But I will say something more plainly, Your Highness. Had you not personally led the attack at Soldau, I do not believe we would be standing in this position tonight."
Oskar's expression shifted slightly.
François continued.
"The men know it as well. They watched their Crown Prince ride over their positions and into the Russians. They watched bullets strike you. They watched you disappear into the fighting."
His hard face softened into the faintest smile.
"And then they watched you come back."
He raised his glass.
"Believe me when I tell you this: they are yours now. There is no commander alive whom those men would rather follow."
Rommel, standing among generals old enough to be his father, straightened with unmistakable pride.
"Until death, if necessary."
The words were spoken without hesitation.
François placed a closed fist over his heart. Mackensen followed, then Seeckt, Ludendorff and finally Hindenburg.
"With you until death, Your Highness."
For a moment the room fell silent.
Oskar drank with them, while Patricia and Elise watched from the edge of the room with quiet pride. He inclined his head and accepted the devotion without false modesty, yet the words brought him little of the satisfaction the others clearly expected.
Death.
He had seen rather too much of it already.
More battles were coming. More armies. Longer fronts. More graves. The Russian dead he had seen during the previous four days would have been enough to cripple a smaller nation for a generation.
For Russia, they were only the beginning.
"You praise me too highly," Oskar said at last.
His voice remained calm and courteous, though something heavier lay beneath it.
"I appreciate what you are saying. Truly. But I could not have done any of this without you."
His eyes travelled around the table.
"Hindenburg. Ludendorff. François. Seeckt. Mackensen. Rommel. The staff. The officers beneath you. The engineers, railwaymen, mechanics, aircrews and soldiers."
He lifted his glass.
"I gave you ideas. You turned them into an army."
The generals listened in silence.
"You trained the men. You moved the formations. You adapted when the situation changed and acted without waiting for me to tell you what you already knew needed to be done. While I was riding around the countryside with a sword, you were directing hundreds of thousands of men."
That earned several disbelieving looks. Oskar continued before anyone could interrupt.
"This victory is not mine alone. It belongs to all of us."
He raised the glass a little higher.
"And most of all, it belongs to those who are no longer here to celebrate it."
The cheerfulness around the table softened.
"So let us drink not merely to victory, but to the army—and to the glorious dead who paid for that victory."
Hindenburg raised his glass.
"To the army."
"And the fallen," Oskar added.
The others repeated it.
They drank.
That, too, was pure Oskar.
Even after four days of industrial slaughter, he thought of Germany as he always had: not as a throne with millions beneath it, but as a single living organism in which every hand, factory, railway, farm, soldier and officer performed some necessary function. No one part could honestly claim the achievements of the whole.
Ludendorff nevertheless shook his head.
"Your Highness, you are entirely too modest."
There was no flattery in his voice.
"If not for you, there would be no Black Legion to command. No armoured divisions. No air arm of this kind. No wireless network. No motorised supply system. No industries capable of replacing what we lose almost as quickly as we expend it."
He gestured toward the maps around them.
"The men did their duty. We did ours. But you created the circumstances in which our duty could produce this."
The other generals nodded with complete seriousness.
Oskar merely smiled faintly and said nothing more. He knew what he had done. Not only to the army, but to the Empire itself. His work now ran through nearly every artery of Germany: its factories, roads, fuel networks, railways, weapons, medicine, communications and military institutions. The victory unfolding around them had not appeared from nowhere. It was the result of years spent forcing the German state to become something capable of surviving the war he had always feared would come.
And if Germany ultimately won this war, it would be because Oskar had spent those years remaking the Empire into something capable of winning it.
The High Seas Fleet alone bore little resemblance to the force he remembered from the other history. Its gunnery, doctrine, ship design and readiness had all been dragged forward by years of relentless pressure. Behind it stood a submarine arm far stronger than anything Germany should yet have possessed, and beyond even that were two aircraft carriers still undergoing intensive trials and training, but already approaching combat readiness. When the decisive naval struggle came—and Oskar had little doubt that it would—those ships and everything built around them would matter.
None of it had appeared by accident. It had been imagined, financed, argued over and forced into existence by Oskar, with Karl beside him through almost every stage. Yet the war was still far from over.
Warsaw, however, was close. Its fall would mean far more than another victory on a battlefield. Warsaw was the political and military heart of Russian Poland, and taking it would drive a wound deep into the Russian Empire itself. Oskar had failed in his greatest original ambition: he had not prevented the war.
That failure remained. But he had accomplished something else.
Germany had been torn away from the fate awaiting it in the history he remembered. Not merely Oskar's fate, nor that of the Hohenzollerns, but that of the Empire itself.
Thinking of that brought him little pride. Mostly, it brought relief. Relief that Germany had not entered this war blind, weak and unprepared.
Oskar lowered his glass slightly.
"How many casualties have we suffered on the Eastern Front?"
The warmth of the celebration diminished at once.
"And I do not mean the Black Legion alone," he continued. "What of the border troops? The police fighting the Cossack raiders? The civilians? I want all of it."
Germany possessed more than seventy million people now. By European standards it was an enormous population.
To Oskar, it still seemed terribly small. Every trained soldier mattered. Every worker mattered. Every farmer, engineer, mother and child mattered because beneath the numbers were human beings, each carrying a life that existed only once.
Ludendorff answered first.
"A little over two thousand Black Legion casualties, Your Highness. The final returns are still being compiled, but the figure should not change greatly. Most occurred during the night fighting, the assaults upon the more stubborn positions and the pursuit through forests where our artillery and armour could provide less protection."
He glanced toward Rommel.
"Without the 1st Armoured Division, the air arm assisting us, I suspect the number could easily have been much higher."
Oskar nodded slowly.
Two thousand casualties. Most were wounded rather than dead, and measured against the destruction of the Russian Second Army the number was extraordinarily small.
He still could not bring himself to think of it as small.
Two thousand men represented two thousand lives interrupted by bullets, shell fragments, burns, broken bones or worse. Some would recover. Some would return to duty. Others would never walk properly again.
And some families were already receiving letters.
Ludendorff seemed to recognize what was passing behind Oskar's eyes.
Without the reforms, he explained, without the improved weapons, protective equipment, armour, aircraft and motorised support, the butcher's bill would have been considerably higher. Perhaps twice as high. Perhaps worse.
Oskar understood that.
It did not make two thousand casualties feel small.
"But that does not make the dead any less dead," he said quietly, "or the wounded any less wounded."
Nobody answered.
After a moment, Oskar looked toward Hindenburg.
"Now tell me about Germany."
Whatever remained of the celebration disappeared.
Hindenburg's expression hardened into the familiar impassive mask of the old Prussian general as he drew another report toward himself.
After the catastrophe in East Prussia, he explained, the Russians appeared to have sought revenge—or at least some desperate means of forcing the Black Legion to look backward. Beginning on the morning of 29 July, something approaching two thousand Cossacks had attempted to cross the frontier across a wide stretch of country.
Most never penetrated very far. Prepared crossings, border strongpoints, police patrols and local garrisons had stopped or destroyed hundreds. But the frontier was too long and too broken by forests, streams, farms and forgotten roads to seal completely, and enough raiders had slipped through to cause serious damage.
They had struck isolated farms and villages, cut communications, stolen livestock and horses, looted homes and businesses and burned whatever they could not carry. Some bands had reached considerably farther than expected.
The worst incident had occurred at Posen.
Hindenburg delivered the numbers with professional restraint. They remained provisional, but the reports already suggested roughly two hundred civilians killed, together with perhaps another hundred policemen, border guards, reservists and other armed defenders. The wounded numbered several times that. Property losses were approaching twenty million marks and still rising.
Then came the uglier reports.
Murder.
Arson.
Looting.
And atrocities committed against women and girls.
Oskar's face became very still.
At the side of the room, Elise visibly paled. Patricia's fingers tightened around the crystal decanter she still held, her earlier amusement gone completely. Neither woman said anything. They had heard stories of war before.
Hearing what armed men had done to civilians only a few days' journey from where they stood was something different.
Hindenburg stopped there.
Ludendorff did not.
Perhaps because he saw the question already forming upon Oskar's face, or perhaps because he understood that withholding the worst part would accomplish nothing.
There were captives.
The exact number remained unknown, but reports spoke of dozens of German women and girls carried east before the border cordons finally closed. Some may already have been recovered or scattered among different raiding parties. Others had unquestionably crossed back into Russian Poland.
That brought a darkness into the room deeper than the casualty figures had managed.
But Ludendorff had something else.
Hope.
German reconnaissance aircraft had sighted several retreating Cossack groups moving southeast after leaving the Reich, many following roads ultimately leading toward Warsaw. They could not prove the captives had gone with them all the way, but the timing made it unlikely that they had travelled much farther.
More importantly, Warsaw itself had remained largely untouched.
Oskar's standing orders prohibited indiscriminate bombing of culturally important cities, churches, historic monuments and civilian districts wherever military necessity did not absolutely require it. The royal complex and much of central Warsaw therefore still stood intact.
Russian forces had apparently begun using parts of that complex for military administration.
And with the Second Army's command structure shattered, Warsaw had become one of the obvious places toward which surviving officers, couriers, stores and headquarters personnel were retreating.
Whoever had authorised the raids might well be there.
And if the men responsible wished to inspect what their Cossacks had brought home—money, jewellery, captured property and human beings—then the captives might be there as well.
Nobody needed Ludendorff to explain the implications further.
Patricia lowered her eyes.
Elise looked sick.
François's jaw clenched.
Whatever had been done, he said, would be avenged.
Oskar looked at him.
"Revenge does not rescue anyone."
That silenced the room.
If the captives were already dead, vengeance could come afterward. If they were alive, every hour spent preparing vengeance was another hour in which they remained prisoners.
Yet the generals had already prepared the sensible solution.
The map around Warsaw was covered with it.
Several promising crossing sectors along the Vistula had been identified. Sniper teams, artillery and aircraft had spent days weakening Russian positions around them. Engineers had measured approaches and currents, pontoon trains were coming forward, and reconnaissance had marked the roads, forts and railway junctions surrounding the capital.
Seeckt's XVII Corps would remain farther northeast, fixing Rennenkampf's battered First Army in place. François's I Corps and Mackensen's XX Corps would concentrate southward, supported by Rommel's armour and the air arm. Once rested, refuelled and reorganised, assault detachments would cross in boats, secure bridgeheads and allow the engineers to throw pontoon bridges across the river.
Then the tanks could follow.
Given time, nobody around the table doubted Warsaw would fall.
Strategically, there was little reason to hurry.
East Prussia was safe. The Russian Second Army was effectively destroyed. The First Army remained pinned and too badly shaken to resume the offensive without reinforcement. Any additional Russian formations sent against the Black Legion would have to be taken from somewhere else, easing the pressure upon Austria-Hungary in Galicia and allowing Germany's ally greater freedom against Serbia.
The Black Legion could rest, repair and wait.
Behind it, Oskar's Germany was already consuming the conquered territory.
German Energy pushed fuel stores, tanker columns and pump stations southward. Greenway repaired roads, drainage and damaged farmland while railway crews restored the lines the Russians had torn apart. Volksbau surveyed sites for barracks, depots, worker accommodation and eventually permanent housing.
Alongside them came the Church of the New Dawn.
Its sisters, priests and doctors were no strangers to war. The Balkan conflicts had taught them what overflowing hospitals looked like, what happened when refugees outran food and sanitation, how quickly infection could kill more efficiently than bullets and how much human suffering could arrive upon a single railway platform.
Now those lessons were being applied directly behind the Black Legion.
Field hospitals appeared. Casualty stations opened. Ambulances and evacuation trains moved north and west. Kitchens fed wounded men and exhausted civilians. New Dawn clergy buried the dead, comforted families and tried to impose order upon places where war had torn ordinary life apart.
The army advanced.
The state followed behind it.
And wherever both passed, reconstruction had already begun.
Oskar looked across the map for a long moment.
Then he issued his first decree.
Every man wounded in the eastern campaign would receive the finest medical treatment Germany could provide. No economies. No bureaucratic calculations about whether saving a crippled soldier cost more than replacing him.
Those permanently disabled would receive pensions, medical support and ten years of tax exemption. Families that had lost their principal provider would receive the same protection.
Police officers, border guards and civilians killed or permanently injured resisting the Cossack raids would not be excluded merely because they had not worn Black Legion uniforms.
Then Oskar added something else.
Land.
The generals looked up.
Much of the territory before them had already been emptied by retreat, evacuation and scorched-earth destruction. Farms stood abandoned. Estates had been stripped. Villages would require rebuilding whether Germany kept them or not.
If the land remained under German rule when the war ended, Oskar declared, those who had paid for it would receive the first right to settle it.
A soldier crippled taking the east could claim vacant farmland if he desired it. The widow and children of a man killed there would inherit the same right. Policemen, border guards and others permanently injured defending German soil would be considered as well.
And every town that had lost men would remember them.
Names carved in stone. Memorials raised where families could see them. Stones of remembrance for those who had gone east and never returned.
"I will not have a man give Germany his arm or his leg at twenty," Oskar said, "and spend the next fifty years begging because Germany has forgotten him."
His hand rested over the conquered territory.
"They are not ammunition. They are not numbers in a ledger. If they bleed for this land, then their sacrifice gives them a claim upon it."
The declaration was extraordinary.
The war was barely days old and Oskar was already speaking as though the new frontier were his to shape.
Yet nobody challenged him.
This was the Iron Prince.
When Oskar decided upon something, the question increasingly became not whether it would happen, but how quickly everyone else could make it real.
And beneath the radicalism was something none of the soldiers around him could dismiss.
He cared.
Not abstractly.
Not in speeches.
He cared what happened to a twenty-year-old private after the parade ended and everyone stopped applauding.
The generals knew perfectly well what war normally did to such men. A missing arm remained missing after peace was signed. A ruined leg could condemn a labourer and his entire family to poverty. Damaged lungs, blindness and shattered nerves did not disappear merely because politicians declared victory.
Oskar intended to make the state share the cost.
That mattered to them.
Years earlier, many of those same officers had regarded him as a strange young prince with too much money and too many impossible ideas. They had obeyed because Prussian discipline demanded obedience.
Then the impossible ideas had become factories. Factories became weapons. Weapons became formations. And formations had destroyed an army.
Professional trust had followed. Soldau had created something else.
They had watched their Crown Prince do what men usually encountered only in histories of Alexander, Frederick and the warrior kings of another age. He had ridden personally into the enemy, placing himself ahead of the soldiers whose lives he supposedly valued.
Those old heroes belonged to books.
Oskar had done it before their eyes.
Professional loyalty was becoming devotion.
Perhaps even faith.
If the Kaiser and Oskar somehow gave opposite orders that evening, every senior commander around that table knew which voice his instincts would tell him to obey.
Not because they considered themselves rebels.
Because they believed in him.
Oskar seemed almost entirely unaware of how far that belief had gone.
He returned his attention to the map.
His second decree was considerably more immediate.
"The celebration is over."
Something in his voice changed. The officers straightened. Oskar pointed northeast toward Seeckt's XVII Corps.
"Seeckt remains where he is. Keep Rennenkampf occupied. Make him believe our attention is still divided and give him no opportunity to move south."
Seeckt nodded.
Then Oskar's hand moved toward the Vistula.
"The rest of us move tonight."
The room froze. The generals had expected days of preparation.
Oskar intended to give them hours.
The crossing sectors already weakened by German artillery and marksmen would be used immediately. Assault parties and engineers were to move before darkness had fully settled. Boats would cross first, bridgeheads would be carved out on the far bank and pontoon bridges begun under cover of night.
François's I Corps would force the western approaches.
Mackensen's XX Corps would strike farther east.
Rommel would divide the mobile strength of the 1st Armoured Division between them as soon as the bridges could carry his vehicles.
By dawn, Oskar wanted German armour moving on Warsaw from both sides.
Not directly into the city.
Around it.
The two advances would curve inward from east and west, severing roads, railways and reinforcement routes until Warsaw found itself caught between the river and two closing armoured fists.
One avenue south would deliberately remain open.
Not generosity.
Calculation.
A completely surrounded army might decide there was nothing left to do but fight to the death. Give frightened soldiers an apparent road to safety and many would take it.
That southern route would become the escape valve through which the remnants of the Russian Second Army could abandon Warsaw rather than destroy it in a final defence.
German aircraft would watch the road beyond the civilian districts, striking retreating military columns once they had cleared the city.
The Russians would be allowed to run.
The Black Legion would make certain they kept running.
Hindenburg listened to the outline with growing disbelief.
The army was exhausted. Rommel's vehicles needed repair. Ammunition and fuel were still moving forward. A river crossing conducted at night against an enemy defending its own capital was precisely the sort of operation sensible generals preferred to plan carefully.
Oskar knew all of that.
He did not change his mind.
The captives did not have several days.
If they were alive in Warsaw, he intended to reach them before the battle for the city gave frightened Russian officers time to move or kill them.
That was when his eyes settled upon the tiny parachute symbols already scattered around the map.
The staff had considered airborne operations and rejected their immediate use for good reason. Ordinary infantry possessed nowhere near the training required to jump into darkness, assemble under enemy conditions and accomplish anything useful.
Oskar picked up one of the parachute markers.
"Ordinary infantry will not do it."
Another marker followed.
"But the Eternal Guard will."
The room became utterly silent.
Oskar placed the small symbols around Warsaw. Third Company, his own men.
The H-1 bombers would carry them over the city before dawn. Under cover of darkness, the Eternal Guard would make the first deliberate combat parachute assault in history.
But they would not go first.
Oskar placed his glass of apple juice directly upon Warsaw. The base covered the city.
"That piece moves first."
For several seconds nobody understood. Then Hindenburg did, and his expression changed.
"Surely you cannot mean—"
"I do."
Oskar would enter Warsaw ahead of them. Quietly this time. No black armour announcing his presence from hundreds of metres away. No red cloak. No death's-head riding openly beneath artillery fire.
He would infiltrate the city during the night, locate the Russian command if he could, search the royal complex and wherever else the captives might have been taken, and create the opening the Eternal Guard required.
Hindenburg stared at him. Even Oskar could be killed if an entire city closed around him.
Oskar agreed. That was why he would not remain alone.
He arranged the parachute markers around the glass.
The Third Company would fall from the night sky around Warsaw before first light, assemble upon whatever ground Oskar secured and tear into Russian communications and command positions from inside the city.
They would create confusion, find the captives and hold. And unless the Black Legion reached them quickly enough, they would eventually be surrounded and destroyed.
Oskar looked around the table.
That was where his generals came in. He would give them their bridgeheads. He would give them chaos inside Warsaw. They had to give him an army before the Russians recovered.
The scale of it finally settled over the room.
By dawn on 1 August, François and Mackensen were expected to be crossing the Vistula. Rommel's armour would be moving behind them. The air arm would control the sky. Eternal Guards would already be fighting inside Warsaw. And Oskar himself would be somewhere ahead of everybody.
It was outrageous, extremely dangerous, possibly insane.
Ludendorff studied the map. Then, slowly, he smiled, for it had worked once.
At Soldau, Oskar had attacked where no rational Russian commander expected him to attack, and the resulting shock had helped break an entire flank.
Now he intended to do the same thing on a vastly larger scale.
Hindenburg looked considerably less amused, but even he understood the logic. The Russian command was already shattered. Their Second Army scarcely existed. Their officers expected Germany to pause and reorganise after four days of fighting.
Nobody expected the enemy to attack Warsaw tonight. And absolutely nobody expected soldiers to come out of the sky.
Oskar lifted the glass of apple juice, drained what remained, and set it down directly over Warsaw.
"We are not doing this for another city on a map."
His eyes moved across the generals gathered around him.
"There are Germans waiting for us. And while I command this army, no German—soldier or civilian, least of all women and girls carried away in chains—will be abandoned in enemy hands if there is any chance they can still be saved."
There was nothing more to discuss.
Oskar stepped back from the table and gave the assembled commanders one final look.
"I leave the timetables to you, gentlemen. I shall be counting on you to reach Warsaw before my welcome there becomes unpleasant."
With that, he turned and started for the doors.
Patricia stared after him for all of half a second before realizing that he genuinely intended to leave without another thought for himself. She immediately gathered up the crystal decanter and hurried after him, skirts swaying around her ankles as she tried to keep pace with his enormous stride.
"Oskar! At least take some more apple juice with you!"
Elise looked from the untouched pastries to the rapidly disappearing prince and made a small sound of exasperation. She swept up the tray with both hands and rushed after Patricia.
"And you have not eaten a single one! Not one!"
Their footsteps followed his into the corridor, Patricia calling after him to slow down while Elise continued protesting about the perfectly good pastries she had apparently carried there for nothing.
Oskar's reply drifted back through the doorway, already growing more distant.
"Yes, yes. I will eat something."
"You always say that!" Elise called after him.
Patricia's softer voice followed immediately. "Then prove it and take one!"
Whatever Oskar answered next was lost as the doors swung closed behind them.
For several seconds, the six generals remained exactly where they were, staring at the map in silence.
Hindenburg's eyes moved first to the empty apple-juice glass sitting squarely over Warsaw, then to the parachute markers surrounding it, and finally to the doors through which their commander and his two determined attendants had vanished.
The old general released a long sigh.
"So much for half an hour of peace."
That finally broke the tension.
François laughed, Rommel shook his head with an incredulous smile, and Ludendorff had already forgotten the champagne entirely and reached for a pencil.
Hindenburg looked around the table.
"Well, gentlemen, apparently we are taking Warsaw tomorrow."
"Technically," Ludendorff observed, glancing toward the clock, "tomorrow is the first of August."
Mackensen smiled as he leaned over the map.
"Then let us give the month a memorable beginning."
Seeckt, meanwhile, looked toward the XVII Corps marker sitting far to the northeast, well away from the glory rapidly gathering around Warsaw. The faintest trace of annoyance disturbed his otherwise controlled expression.
"So all of you get Warsaw while I remain behind watching Rennenkampf."
That drew another round of laughter.
François reached across and clapped him once on the shoulder.
"Do not look so wounded, Seeckt. At this rate, Saint Petersburg may yet be waiting at the end of your road."
Seeckt glanced toward him, then down at the northeastern edge of the map.
His irritation slowly gave way to the smallest of smiles.
Hindenburg looked at the lot of them and shook his head.
"God help Russia."
Then he reached for the telephone.
The champagne was forgotten. The glasses were left half full. Elise's pastries disappeared down the corridor with their maker.
Around the great table, pencils began scratching, telephones rang, and coloured markers started moving south.
Before the evening of 31 July had ended, the Black Legion was already preparing to march on Warsaw.
