Hasan Tahsin was the code name of Osman Nevres (1888 – 15 May 1919), a Turkish nationalist,[1] [2] patriot, and journalist of Dönmeh descent. [3] [4] [5] [6]
Hailed as a Turkish war hero, his name has been given by the Turkish Armed Forces to the Information Center of the Turkish General Staff (Genelkurmay İletişim Başkanlığı'nın Hasan Tahsin Bilgi Merkezi). A member of the Ottoman Special Organization, he unsuccessfully tried to assassinate Noel and Charles Roden Buxton in Romania during World War I.[7] He was sentenced to five years imprisonment for the attempt but released when German forces overran Romania.[8]
He opened fire on the Greek soldiers who landed at Smyrna (present day İzmir) on 15 May 1919[9] in the opening act of the Greek occupation of more than three years that extended over a large part of western Anatolia, as well as of the Greco-Turkish War. He was killed on the spot on 15 May 1919 after killing the Greek standard-bearer. At the time of his death he had been publishing and writing for the newspaper Hukuk-u Beşer(Ottoman Turkish for Human Rights).[10]
