During the invasion of Poland, Germany bombed Polish civilian refugees on the road from Warsaw to Siedlce, and the city was captured and then occupied by Germany until 1944. The Polish government evacuated the Polish gold reserve, part of which was stored in Siedlce, to Polish-allied France. In mid-September 1939, the German "Einsatzgruppe V" entered the city to commit atrocities against Poles. Siedlce was included within the Warsaw District of the General Government (German-occupied central Poland). During the war, the area of Siedlce was home to a large partisan force of the Home Army and other underground organizations, such as Armia Ludowa. Due to German terror, the town lost one-third of its population, including its entire Jewish community deported to extermination camps during the Holocaust. In late July 1944 (see Operation Tempest), Home Army units freed the town, together with the Red Army. After the war, 50% of Siedlce was in ruins, including the town hall.
