"So war it is" These are only words what Poles waking up in the morning of September 1st heard from their radio's and one's that they shall remember. Poland was getting invaded by Germany,  Polish soliders are currently dying for thier homeland and Polish government is trying to contact it's allies in Paris and London since it heard the news. When Polish Ambassador in France managed to contact French foreign minister he immediately informed President of France that Polish Ambassador needs to talk with him.
"Germany started war" These words said by the Pole in front of him made French president go pale.

"German troops entered Pomeranian, Silesian and Poznan voivodeship and we need France and Britain act fast or we'll be doomed" French president just stood there trying to understand what's actually happening but after realizing he ran off to call British prime minister.
They were talking till September 6th while getting letter's from Poland, and one day later they decided that they shall  attack from the west.
French troops entered Germany crossing Maginot line with British soldiers not meeting any big resistance from Germans.

Situation in Berlin was getting worse when they heard that Allies decided to intervene. Hitler was shouting at his generals that they should move armies to the west and that they will crush Poland anyways when these filthy communist's from Russia get into this ugly product of Versailles. German minister of foreign affairs sent letter to Warsaw.
"We want armstice to not spill any more blood of innocent people, our demands are that Polish troops shall leave West Prussia , Danzig and Silesia they shall remain in provinces of Posen"
Polish foreign affairs minister just looked at it trying to think of what to do but later he got convinced by British to agree for this for at least short term.
When letter accepting German offer came to Berlin it felt like a huge relief for German general's because they could move armies to the west only leaving small border guard in the east. But then on September 17th exactly 6 days later Polish troops after reorganization started offensive into east Prussia, Silesia , and Pomerania.
Hitler meanwhile finally managed to convince Musolini to join the war tho it only led to Italy losing its African colonies and surrendering swearing neutrality, Führer was furious trying to convince his general's that they should punish cowards from Italy but they knew situation was getting worse because Czechoslovak partisans started uprising in Prague and were winning it already taking big part of it with help of hated by them but not hostile towards them Poles.
On night of September 29th Stalin still did nothing to help German's and Hitler was woken up at 4AM tho it was rather just breaking into his room because he couldn't sleep.
"Kanzler Hitler, you're getting arrested in the name of his Imperial Majesty Herman Von Göring" solider said calmly when other 2 disarmed Führer of the Reich. Civil war started with Hitler's old allie all the way up as new emperor of military government of German empire.
Göring's army was ordered to not fight Allies only soldiers still loyal to Hitler and Goebbels. He even sent letter with proposal of peace saying that National socialism is their enemy too.
But after a week when Poles with Brits and French were getting close to Berlin at October 4th he knew that they were disarming his soldiers so he took the poison and was found dead in the KaiserBunker it was end of short lived IV Reich
When Allied armies entered Berlin they found Hitler , Goebbels, Himmler and Ribbentrop in prisoned and they got sure they kept them here until they can finally punish these main war criminal's to kill the third Reich at it's heart.
At the noon time of October 18th Himmler , Goebbels and Ribbentrop got sentenced and publicly hanged, meanwhile what happened to Hitler is unsure after the war but there were speculations he ran off.
On October 20th Germany capitulated and got divided into 3 occupation zones and Poland annexed east Prussia, Danzig and rest of Silesia. Meanwhile Czechoslovaks got part of historical Bohemian lands and new Slovak government united with Czechs making new Czechoslovak federation which still had claims towards southern Slovakia and Carpathian Ruthenia to Hungary but didn't took any Claims towards Poland.
It was end of the Germany we all knew in 30s. And it ended with 3 Flags of victorious countries waving above Berlin.

So it's first chapter of the Remake, hope it will be worth it!
