On June 15th 1941, ten Polish residents were shot dead in public execution on the wall of a church in Gąbin, Poland, which was under German occupation, on the Eastern Front of World War II.

 　On the eastern front of World War II, ten Polish residents were shot dead in public execution on the wall of the church in Gąbin, Poland, which was under German occupation, on June 15th 1941. The residents of Gąbin were forced to gather in the market square to watch the public execution.

　　Gąbin was invaded by the German army during the invasion of Poland, which marked the beginning of World War II on September 1st 1939. The German army entered Gąbin and the surrounding towns on September 17th 1939, and a cruel period of occupation began. The Polish people suffered various cruelties at the hands of the German army. The German army immediately arrested a large number of local Poles and deported them to the Mauthausen concentration camp, where they were killed. The Germans also carried out massacres of Poles in Gąbin itself.

　　From the beginning of the war against Poland, the German army carried out massacres and executions of civilians. Many German soldiers massacred and executed civilians. Mass executions were carried out in public places such as town squares to instill fear. Between December 7, 1939 and July 17, 1941, around 1,700 Poles were killed in secret executions.

　　It is estimated that around 6 million Polish citizens died during World War II. Most of these were civilian Poles killed by military action by Nazi Germany, the Soviet Union and the Lithuanian Security Police. Others included Ukrainian nationalist organizations and factions. In occupied Poland, war crimes were committed on a scale that was unprecedented in the rest of Europe.
