In 1918, the Entente defeated the Triple Alliance and divided German territory between France, England and Poland. Russia, as an ally of Germany (after the conclusion of the Brest-Litovsk Treaty), also fell under the territorial division of America, Poland, Japan, England and France. The Poles began building Greater Poland on the territory of Russia and Germany. Polish sanitation legions cleared the lands of local residents, driving them into concentration camps, preparing them for settlement by Poles. Whites and Reds stopped shooting at each other and united against a common enemy. The population began to join the partisans. At the same time, the Germans of the Ruhr region received an order from the French to destroy all factories and destroy equipment. After the French shot at a demonstration of German workers, the Germans opened military warehouses and armed themselves. The book then tells about the military actions of the Russians and Germans against the Poles, French and Americans on land, water and in the air.
