On March 4, the Bulgarians placed most of the Jews in Thrace, which had been annexed to Bulgaria in 1941, in confinement. According to Bulgarian statistics, 4,058 Jews were handed to the Germans and sent to Treblinka, where they were murdered at once. Approximately 200 Jews survived in Thrace amongst the partisans or hidden by their Christian neighbors, including 42 young men who were in Bulgarian labor camps.
