Between 1939 and 1943, hundreds of thousands of Jews were trapped in over 400 ghettos in the occupied lands of Eastern Europe. By the summer of 1944, all the ghettos had been evacuated and most of the prisoners had been exterminated. When did the world learn about the genocide that was taking place in the heart of Europe? What did the Allies do to stop the slaughter? Why was the Jewish leadership in Palestine so slow to react? Was there a Jewish resistance? What was the role of the Greek Jews in the Sonderkommando revolt? Could Chief Rabbi Koretz have prevented the extinction of the Jewish community of Thessalonica? Why were the Jews who had gathered in Athens saved? Who organized the rescue operation in the Aegean? The agreements between the British secret services, the Jewish Agency and the National Resistance Front of Greece opened the way for the escape from Euboea.
