ETO: At Bedzin, 200 Polish Jews are burned alive in a synagogue by the Germans who charge Poles with the crime, and then execute 30 of them in a public square.
A typical burning Jewish synagogue during WWII
The Germans instituted a special campaign of burning down synagogues, or, after destroying their interiors, turning them into stables, warehouses, bathhouses, or even public latrines. In Bedzin, flames from the burning synagogue spread to neighboring Jewish houses. The area was cordoned off by soldiers and SS-men who did not permit anyone to escape or to fight the fires. The rabbi of the community was forced to sign a "confession" that the Jews themselves had started the fire and was ordered to pay heavy fines as punishment for the "arson." The Jewish community was also compelled to bear the cost of tearing down the remaining walls of the houses and clearing the rubble.
