In Odessa, between 80,000 and 90,000 of the city's roughly 180,000 Jews remained at the time the Germans and Romanians captured the city on October 16, 1941. Six days later, a bomb exploded in the Romanian military headquarters in Odessa, prompting a massacre of Jews; many were burned alive. In October and November 1941 alone, Romanian troops in Odessa killed about 30,000 Jews. Transnistria was the site of two concentration camps and several "de facto" ghettos (which the Romanian wartime government referred to as "colonies"). In addition, most of the remaining Jews in Bessarabia (84,000 of 105,000) and northern Bukovina (36,000 of 60,000) were herded into these as well. A striking paradox is the fact that most of Romanian Jews (375,000) under Antonescu regime survived WW2. The "Holocaust Encyclopedia" (United States Holocaust Memorial Museum) writes that "Among the most notorious of these ghettos… was Bogdanovka, on the west bank of the Bug River… In December 1941, Romanian troops, together with Ukrainian auxiliaries, massacred almost all the Jews in Bogdanovka; shootings continued for more than a week." Similar events occurred at the Domanevka and Akhmetchetkha camps, and (quoting the same source) "typhus-devastated Jews were crowded into the 'colony' in Mohyliv-Podilskyi." Other camps, also with very high death rates, were at Pechora and Vapniarka, the latter reserved for Jewish political prisoners deported from Romania proper. Many Jews died of exposure, starvation, or disease during the deportations to Transnistria or after arrival. Others were murdered by Romanian or German units, either in Transnistria or after being driven across the Bug River into the German-occupied Ukraine. Most of the Jews who were sent to the camps in Transnistria never returned. Those who survived, around 70,000, returned to Romania in 1945 to find that they had lost their houses.
