On this day in 1941, more than 23,000 Hungarian Jews are murdered by the Gestapo in occupied Ukraine.

The German invasion of the Soviet Union had advanced to the point of mass air raids on Moscow and the occupation of parts of Ukraine. On August 26, Hitler displayed the joys of conquest by inviting Benito Mussolini to Brest-Litovsk, where the Germans had destroyed the city’s citadel. The grand irony is that Ukrainians had originally viewed the Germans as liberators from their Soviet oppressors and an ally in the struggle for independence. But as early as July, the Germans were arresting Ukrainians agitating and organizing for a provisional state government with an eye toward autonomy and throwing them into concentration camps. The Germans also began carving the nation up, dispensing parts to Poland (already occupied by Germany) and Romania.
