In the first half of March 1943, Bulgarian military and police carried out the deportation of the majority of non-Bulgarian Jews, 13,341 in total, from the occupied territories, beyond the borders of Bulgaria before the war, and handed them over into German custody. On the eve of the planned deportations, the Bulgarian government made inquiries regarding the destination of the deportees and asked to be reimbursed for the costs of deportation. German representatives indicated that the deportees would be used as labor in agricultural and military projects. As recorded in the German Archives, Nazi Germany paid 7,144.317 leva for the deportation of 3,545 adults and 592 children destined for the Treblinka extermination camp. 4,500 Jews from Greek Thrace and Eastern Macedonia were deported to Poland, and 7,144 from Vardar Macedonia and Pomoravlje were sent to Treblinka. None survived. On March 20, 1943, Bulgarian military police, assisted by German soldiers, took Jews from Komotini and Kavala off the passenger steamship "Karageorge", massacred them, and sank the vessel.
