Order issued from Constantinople by Talat Pasha 27 May 1915 (Tehcir Law). Erzurum, a major regional centre with an Armenian population of approximately 25-30 thousand in the city plus surrounding rural villages, was emptied in three columns through July-August 1915. Eyewitness reports collected by Bryce and Toynbee include the consul Leslie Davis report from neighbouring Mamuretulaziz, the German military attaché Otto von Lossow's reports compiled in Gust, and the testimony of survivors collected by Morgenthau at the U.S. embassy in Constantinople. Standard demographic estimate (Hovannisian, Karpat triangulated) places the killed-and-died at approximately 220,000 from a pre-war community of approximately 215,000-260,000.
