Although the Hungarian army attached to Rundstedt’s Army Group South did not take part in mass killings, the Romanians attacking Odessa, a city with a large Jewish population, committed appalling atrocities. Already in the summer of 1941 Romanian troops were said to have killed about 10,000 Jews when seizing back the Soviet-occupied areas of Bessarabia and the Bukovina. Even German officers regarded the conduct of their ally as chaotic and unnecessarily sadistic. In Odessa, the Romanians killed 35,000.
