In the immediate aftermath of the First World War, the army of the resurrected Polish state wore both German and French uniforms.
French uniforms were worn by members of the Haller Army, a formation formed in France commanded by General Haller. It fought on the Western Front as part of the French Army, and returned to Poland in 1919. Because of its wartime experience as a unit, it formed the backbone of the new Polish Army.
Units raised in Poland after the end of the war and the establishment of an independent Polish state generally were equipped with surplus German uniforms and equipment. General Pilsudski and the men of his POlish Legion wore Austrian uniforms.
What happened in Posen Province in 1920-22, after it was handed over to Poland under the provisions of the Versailles Treaty, was that Polish nationalists tried to drive out the ethnic German minority by force of arms. The German Freikorps entered the province to protect the ethnic Germans.
The bitterness created by the Polish attempt to ethnically cleanse the Posen Province (or Poznan to give it its Polish name) provided the fuel for the atrocities committed by German forces when they retook the region in 1939.
