As for the matter of Germany ceding territory, we have to mention the extent of the territory Germany had left after World War I.
As a country that had already been carved up once after World War I, Germany had very little land left to cede.
And when all was said and done, among the three countries of Britain, France, and Australasia, only one could effectively annex German territory—and that was France, which was already champing at the bit.
Britain and Australasia did not border Germany directly. Even if they obtained German territory, they were destined to be unable to turn it into part of their mainland.
To prevent the French people from taking too much advantage, the United Kingdom and Australasia reached an agreement: the total area Germany ceded could not exceed 15% of its existing mainland territory, and the occupation would primarily consist of garrisoning troops to effectively guard against the possibility of revenge once Germany regained its strength.
First came the land Germany needed to cede.
The Free City of Danzig and the East Prussia region would be directly annexed by Poland. Poland would establish a Kingdom Government and become the most powerful country in Central Europe.
Everything north of the Kiel Canal would be ceded to Denmark, while the Kiel Canal would be jointly administered by Britain, France, and Australasia.
Saarbrücken, north of Alsace and Lorraine, would be ceded to France. This was also the only territory France could obtain after the war.
Silesia, between Bohemia and Poland, would be placed under the Polish Government's administration for twenty years. After twenty years, a referendum would be held to decide the fate of the entire Silesian region.
Aside from the territories being ceded, Germany as a whole would be divided into three zones occupied by the troops
