On the occasion of the 100th anniversary of the tragedy that struck the Hellenism of Asia Minor and Thrace, historical research continues to present opportunities that shed new light on the developments of that time. The unpublished material is vast in volume, and this book is a prime product of unknown information and data. Focusing on the controversial figure of Aristeidis Stergiadis, High Commissioner of Smyrna from 1919, the narration of the tragic days of August 1922 unfolds through the correspondence of the responsible authorities from the war front and the General Headquarters in Smyrna to the High Commission of Smyrna and the government in Athens. With the help of archival sources and previously unknown official documents, the reader will discover new unexplored aspects of the entire drama. In the short period of 14 days from the Kemalist attack to the capture of Smyrna, the correspondence of the High Commissioner with the government, the information and proposals he submitted, the governmental crisis that erupted, the initiative for a possible Allied intervention in the city of Smyrna, and the unprecedented situation that developed with the refugees who flocked are revealed. At the same time, an evaluation of the subsequent explanations of the High Commissioner is attempted, leading to the dispelling of erroneous impressions and entrenched judgments about the Asia Minor Catastrophe, with the valuable material from the relatively unknown Aristeidis Stergiadis Archive as a focal point.
