Poland held a state burial on Monday for over 700 victims of Nazi Germany's World War II mass executions, recently discovered in the Valley of Death in northern Poland. The ceremony took place in Chojnice, featuring a funeral Mass and military honors at a local cemetery, attended by President Andrzej Duda and officials from the National Remembrance Institute. Exhumations conducted between 2021 and 2024 revealed the remains of Polish civilians, including 218 asylum patients, with some identified as teachers and priests. Historians confirmed that these atrocities began shortly after Germany invaded Poland in 1939, with further executions occurring in January 1945 during the German retreat. The war caused Poland to lose 6 million citizens, including 3 million Jews, alongside significant infrastructural and economic damages.
