I had no idea that Choszczno, former Arnswalde, a big town, was fully destroyed and never reconstructed. Its bricks were sent to rebuild Warsaw. Only the cathedral was rebuilt. Pity.
en.wikipedia.org/wiki/Choszczno In 1939, short after the beginning of Second World War, the prisoner of war camp Oflag II B was established on the outskirts of the town. At the beginning, the majority of the prisoners were Polish and French. The Poles were used in the city as slave labor by the Germans.
With the collapse of the German eastern front throughout the Red Army Vistula-Oder Offensive of 1945, Arnswalde was on the front line. Because of the town's strategic position of protecting Stargard and Stettin seaport, a strong German garrison had been concentrated within the town to defend it. During the Russian offensive bitter fighting occurred, which resulted in almost 80% damage of the town's infrastructure. After the German resistance stopped on 23 February 1945, Arnswalde, now Choszczno again, was handed over to the Poles for administration as a part of the so-called Recovered Territories.
The German inhabitants either fled westwards or were expelled. The town was mainly repopulated by Polish expellees from the Polish territories lost to Soviet Union, now part of Lithuania, Belarus, and Ukraine—the so-called Kresy, lands eastern to the Curzon Line. It was initially renamed as Choczno, later as Choczen in 1945. It was finally renamed as "Choszczno" on 7 May 1946.
