Romanian soldiers and gendarmes also worked with the "Einsatzkommandos", German killing squads, tasked with massacring Jews and Roma in conquered territories, the local Ukrainian militia, and the SS squads of local Ukrainian Germans (Sonderkommando Russland and Selbstschutz). Romanian troops were in large part responsible for the Odessa massacre, in which from October 18, 1941, until mid-March 1942, Romanian soldiers in Odessa, aided by gendarmes and police, killed up to 25,000 Jews and deported more than 35,000.
