Although Gustav Stresemann was elected to the Constituent Assembly of the Albert Cabinet in 1918, he did not approve of this government. The uprising that broke out in the country, Albert used the army to suppress it, but the lack of decisive decision-making led to the expansion of the uprising. There was also a lack of assertiveness in the foreign peace approach, and the weak Ebert government disappointed Stresemann. The Federalist invitation in early October did not give Gustav Stresemann any hope, and Eric Adrian was not heard from after the telegram of the invitation to join the party, and Stresemann was equally unkind to the field marshal who had made great contributions to the Empire. The main reason is that Eric Adrian's businessman aura is too heavy, and if it weren't for the fact that he was about to be hit, he was afraid that it would be difficult to stand up.

Almar Schacht, and Gustav Stresemann were old acquaintances, and they both had their own views on the government formed by Albert, but after all, Schacht had more contact with Adrian and knew Adrian better, so he responded as soon as the latter made a telegram to join the party. While Adrian was passing through Berlin, Armar Schacht was secretly asked to go to Hanover. His first thought was to take Gustav Stresemann with him, who did not resist, so when Adrian formed his cabinet in Hanover, Stresemann was also elected to the Constituent Assembly.

Since he wants to form a cabinet, the selection of the prime minister has become his number one problem, and if this person is not selected well, the entire cabinet will have to collapse together, and it must be in line with his own interests. He agreed to speed up the pace of ending the war, but firmly opposed unconditional surrender, which would be a serious blow to Germany's international standing and to Germany's own strength.

He told Hindenburg what he meant, and the latter expressed his support, and Adrian began to look for someone close to him. Gustav Stresemann came to his sights through a number of recommendations. That evening, Stresemann met Adrian for the first time on Schacht's recommendation, and the conversation between the two did not end until it was getting dark.

The next morning, in his capacity as President of Germany, Eric Adrian sent a telegram to Hermann Müller, who was negotiating surrender with the Entente, asking him to suspend the peace talks. Immediately after an uproar, Friedrich Ebert sent a telegram condemning Eric Adrian's puppet government, demanding that the latter immediately dissolve the puppet government and go to Berlin to stand trial for treason.

On 10 October, Max Gang was ordered to leave the Western Front and return home to assist Eric Adrian in quelling the rebellion, along with the 1st Panzer Division and two adjacent Saxon Infantry Regiments, totaling 35,000 men. While Rundstedt was on his way to Hanover, Eric Adrian announced the appointment of Gustav Stresemann as Chancellor of Germany, tasked with forming a cabinet. On the morning of October 11, Chancellor Stresemann announced the list of cabinet members and sent a telegram to the whole country. Almar Schacht as Minister of Economy, Franz von Papen as Minister of Foreign Affairs, Hermann Müller as Deputy Minister of Foreign Affairs, Heinrich Brüning as Minister of Political Affairs, Walter Brauchitsch as Commander-in-Chief of the Federal National Army, Paul von Hindenburg as Vice President, Max Hoffmann as Chief of the General Staff of the National Army, etc. The German National Army was formally established, with Rundstedt, who led the 1st Panzer Division, as deputy commander-in-chief of the National Army, Max Hoffmann as chief of the General Staff, and Hindenburg as commander-in-chief of the National Army.

By the time Stresemann announced his cabinet list, there was a huge wave of opposition to the Albert government across the country. Friedrich Ebert knew that something was wrong when he learned that the Germans were supporting Eric Adrian on the Western Front, but Eric Adrian did not send any telegrams to his government, not a single one!

Albert was now desperate, since he formed the Provisional Government, there had not been a day of tranquility in Germany, and the whole country had revolts and riots, and troops had been sent to suppress it again and again. Successive waves of uprisings were eroding the credibility of his government, and the people no longer had much hope for his government. And when Eric Adrian announced the formation of a government, the addition of the German army on the Western Front undoubtedly gave everyone hope. The mythical achievements on the Eastern Front are still well known, and his deeds have become the hottest topic in Germany.

In the German Junkers, Albert and Adrian are equally statused. But there were also different factions within the Junkers, and the military-dominated line was clearly more fond of Adrian. In the common class, the contrast between Albert and Adrian is not obvious, and the German Social Democratic Party, with the working class as the main body, is bound to contradict the business owners. Adrian was relatively well behind him, with more business owners to support him. Anthony Fokker ordered the aircraft assembly plant to stop supplying all military supplies to anyone, and sent a telegram to Adrian in Hanover, where the stock was awaited. There are many more people in this situation, but there are also many people who are on the sidelines. Some of them did not dare to gamble with their lives because they were still in the area controlled by Albert, and some did not agree with Adrian's approach, believing that he was adding fuel to the fire.

No matter what Adrian did, there were some people who couldn't agree with him, so he didn't plan to settle the matter peacefully.

On October 14, 1918, Max Hoffmann arrived in Hanover and presented his battle plan to President Adrian.

The Backyard Plan was a rapid and unified plan developed by Max Hoffmann after receiving a secret telegram from Adrian and providing national intelligence. The Albert government's control over the controlled areas in southern Germany was weak, and the southern part of Germany was already the backyard of the insurgents, so Max Hoffmann planned to send the main force to the south to recover the southwestern part of Germany. Due to the strong control of the Albert government, the northern region is not easy, because of the small number of troops, the northern part is mainly contained, supplemented by capture.

Although the troops are not enough, Max Hoffmann appears to be very confident, which is a kind of trust in Eric Adrian.

Adrian put the Backyard Plan on the table of a temporary cabinet in Hanover, where Vice President Hindenburg oversaw the war on the Western Front and Hermann Müller negotiated peace in France.

The meeting ended with the full approval of the "Backyard Plan", and Adrian formed the Lower Saxony garrison with the arriving German troops on the Western Front into the National Army, which was divided into three corps: 1, 2, and 3. The command of the 1st Army was Admiral Rundstedt. The 2nd Army was commanded by William Loeb and Erich Manstein as chief of staff. The commander of the 3rd Army was Erwin Witzleben as commander, and Heinz Guderian as chief of staff.

On October 17, Max Hoffmann ordered the start of the operation at the Provisional General Staff in Hanover.
