Friedrich "Fritz" Schubert (; 21 February 1897, Dortmund – 22 October 1947, Heptapyrgion) was a Greek-speaking German NCO Oberfeldwebel (Sergeant) of the Nazi Wehrmacht. As head of the Jagdkommando Schubert, a semi-independent paramilitary force he terrorized the civilian population during the Nazi occupation of Greece in World War II and he committed numerous atrocities in Crete and Macedonia. Tried by a special court for war criminals in Athens, he was found guilty over the killing of over 250 civilians, sentenced 27 times to death and executed. Earlier life Few details of Schubert's pre-WWII life have been verified. Some Cretans believed that Schubert was born as Petros Konstantinidis () (the name he used when he was arrested by the Greek Police), son to a rich tobacco merchant in Smyrna and a Turkish mother and emigrated to Germany at a young age. There, he joined the National Socialist Party and became a dedicated Nazi. However, it is verified that Schubert was German, born in Dortmund in 1897. During WW I He served in the Imperial German Army, and possibly fought in Turkey. He claimed that he was decorated with the Iron Crescent medal and he was proudly displaying it. In 1918 he possibly returned to Dortmund and became machine fitter (machinen monteur). He returned to Turkey in 1920s, where he worked for the Turkish authorities. Schubert in 1925 married an Italian woman in Smyrna and emigrated in Alexandria, Egypt where he stayed for about fifteen years. He became a member of NSDAP in January 1934 and after the outbreak of WW II, Schubert returned to Dortmund, Germany. In April 1941 when Germany invaded Greece he joined the Ersatzheer, he was trained as a military interpreter (he already spoke Greek, Turkish, Italian and Arabic) during April and May 1941 and was promoted to Unteroffizier (corporal) in June 1941. As a Wehrmacht non commissioned officer Schubert made his first appearance on Crete in summer 1941 as military interpreter to the Local German Command (Ortskommandatur) in Chania under general Alexander Andrae commander of occupied Crete. Possibly during August 1941 he was transferred to the Regional German Command (Kreiskommandatur) in Rethymno. In autumn 1941 Schubert was transferred again to Heraklion to the Abwehr (counter-espionage) detachment under the command of Greek speaking major Hartmann (first name unknown). As he could speak Turkish and had a strong Turkish accent when speaking Greek, Cretans nicknamed him "the Turk". Major
