With the acceptance of their surrender the German navy would follow the orders of their new captors. Junior, Warrant and Non-Commissioned Officers would submit to their general POW status while senior officers were taken to isolation without resistance. Those Germans left on their ships would sail to Estonian ports with all systems that posed any military significance disabled while Athenians oversaw them. Many feared what would happen to them now, but all feared what would happen to them and their families if Germany somehow managed to win this war.
The German Air Force was quite frankly in deep shit. Those planes on the ground could not take off and those still in the sky were running out of fuel and hunted by their enemy. In acts of desperation pilots would land wherever they could and if they couldn’t land they would just eject. But Germany had lost its airspace completely. The price of angering the world without state of the art technology. Pilots found after landing or ejecting would be arrested by the Gestapo for cowardice to be prosecuted by emergency military tribunals. Usually those caught would be dead within a day.
The army was the only element of the Greater German Empire still making its country and its Chancellor proud. Reports had confirmed that the Kaiser had died in one of the Athenian airstrikes on his palace, leaving the Chancellor in full control of the country. Without a navy and Air Force, the challenge for the Army was bigger than ever. Facing constant tactical and strategic bombing by the Athenian and Polish Air Force while shore bombardment by their navies created entire no go zones deep into German territory, the German Army could focus only on the defense of its most important locations. Berlin, the industrial heart in the West and the political heart of the movement in the South.
The Athenian Marines would face no trouble taking Wilhelmshaven, however as they marched on and the number of German soldiers increased, resistance was increasingly stronger. For now.
In Hamburg an elderly gentleman entered City Hall, the uniform he was wearing barely fit. Probably owing to the consumption of Bratwurst after retirement. General Reinhard Steiner was the regional commander of the Volkssturm. The reserve and militia force of the German military that served to defend the Empire when all else failed. With the numbers they were facing this force had been activated and integrated into the regular German army. This was something Schmidt would soon find out to be a fatal mistake. Where the German army were zealots, completely brainwashed by the philosophy of the Chancellor, the Volkssturm had not yet been subject to the same. Its command was mostly from the old Republic and its soldiers were politically ambivalent or opposed. There were some that supported Schmidt, but that number was going down by the day. Especially in the North-West of the country that traditionally leaned more to the left. As Steiner walked past the active duty Lieutenants and Colonels, very little thought was spent on the dozen soldiers that escorted Steiner. After all, the elderly were known to suffer from delusions of grandeur and expecting a full force of security to be with them at all times. As he entered the room where the Army Generals prepared their defense of Hamburg the soldiers would raise their rifles and promptly disarm the soldiers standing guard inside. “Gentlemen, I will keep things simple. The German People’s Republic has declared you all war criminals. I have been ordered to arrest you for extradition and prosecution by the Athenian Federation” While Steiner spoke throughout the city units of the Volkssturm overtook their active duty counterparts. The German Army might be more experienced and have better weapons, however the Volkssturm outnumbered them and had the element of surprise with them. As soldiers were disarmed and facilities that held Athenian prisoners placed under Volkssturm control these reserves and militia units would act quickly to prevent a power vacuum and established martial law.
“What the hell are you doing Steiner? The German People’s Republic? Has the beer gone to your head?” General von Appen, Reichskommandant of the province said as he moved towards the Volkssturm general. Only to be stopped by one of the soldiers.
“I am the only one here who hasn’t lost his mind. This war is unwinnable and we deserve to lose it. The Chancellor has betrayed Germany by making the German people responsible for genocide again. If you care about your soldiers you will order them to stand down. The Volkssturm has surrounded this building and is taking over the streets. The Greater German Empire has no authority here.”
The Army commanders were unwilling, however they were even less willing to give up their lives. In the end they would agree to issue the order to all soldiers under their command to submit to the Volkssturm. As this happened a broadcast would be aired within Germany and internationally. From the Hanseatisches Oberlandesgericht a woman with red hair appeared.

"Germany is under attack. Not by the forces from Athens or Warsaw but by those from Berlin. Rudolf Schmidt and those that have condoned his behavior have invited devastation to Germany. Many have warned for years that the policies proposed had only one way they could end, and all have been proven right. It is the responsibility of all good people to rise up against evil. I am pleased to say that there are still good people in Germany. People that will fight injustice, as long as they have a cause then can rally behind. I today offer all of you that cause. I am hereby declaring the existence of the German People’s Republic as the true and rightful German state in line with the peace treaties signed after World War 2 and am declaring the administration of Rudolf Schmidt to be illegal. For their crimes against the German and Athenian people I am ordering their arrest. As we speak the Volkssturm are disarming the German Army and establishing security within Germany. Do not fear these soldiers, they are only here to protect you against the fascist forces.
To the world, in particular the governments in Athens and Warsaw. You do not know me, you likely do not trust me. My name is Julia Bonk and I have fought this government for years. The German people are not your enemy, the crimes committed against the Athenian people are unforgivable but I beg you to not punish innocent Germans for a crime forced upon them by the forces of evil. I will gladly meet with you to discuss the future of a free Germany. I have ordered the Volkssturm to not engage your forces. Germany does not want war, only the fascists do.
As the message was broadcast Polish and Athenian forces in the North would find the resistance very suddenly dropping and likely would even see German soldiers fighting other soldiers as those areas where the Volkssturm and Army were more evenly matched turned violent. When Athenian soldiers arrived in Hamburg the local Volkssturm command would offer to meet with their unit commander. The same would happen in Lubmin.
While the Volkssturm and DVR controlled the North and North-West, the rest of the country was either up in the air or still solidly under control of Berlin. Initial confusion and fights with Volkssturm units meant that Athenian and Polish forces could likely advance quite a distance. But by the time they reached major German cities the defense would once again be solidly under Army control. High Command would issue orders to shoot any traitor on sight and to dig in to halt the enemy offensive as long as possible.
