Final answer:
The German soldiers conducted mass arrests of Jewish community leaders on November 9-10, 1938, during Kristallnacht, with further arrests and resistance such as the Warsaw Ghetto Uprising in April 1943.
Step-by-step explanation:
German soldiers arrested leaders of the Jewish community and tens of thousands of Jewish men during the Kristallnacht, or Night of Broken Glass, which occurred on November 9-10, 1938. This event marked a significant escalation in the Nazi regime's persecution of Jews, which included orchestrated violent attacks, destruction of synagogues, and mass arrests.
The Warsaw Ghetto Uprising began on April 19, 1943, when the ghetto's residents took up arms in resistance against the deportations to concentration camps. Sadly, the organized resistance came to an end on May 16, 1943, with individual efforts continuing thereafter.
During the war, other significant roundups and arrests occurred as the Nazis implemented their genocidal policies across Europe. This includes the formation of ghettos in Polish cities such as Warsaw, mass executions by the Einsatzgruppen, and the systemic forced labor and eventual mass deportation of Jews to extermination camps, with the Holocaust research showing the tragic depth of these atrocities.
