Transport Ez-St 66 left Prague (Praha) to Theresienstadt on 13.09.1943. It consisted of 15 Jewish deportees. This transport was listed as Ez-St, the German initials for special transport of individuals (Einzelreisende Sondertransport). These transports usually consisted of the relatives of members of the Jewish council in Theresienstadt, Jews arrested by the Gestapo, or Jews who had been brought to Prague from other cities in the Protectorate.
Between December 1943 and October 1944 ten of the 15 deportees that had arrived to Theresienstadt with transport Ez-St 66 were re-deported to Auschwitz and subsequently murdered. One additional deportee perished in Theresienstadt. Only 4 of the 15 people survived the Shoah.
