The Yalova Peninsula massacres
were a series of massacres and ethnic cleansing
during 1920–21, the majority of which occurred during March – May 1921. They were committed by local Greek and Armenian gangs and the invading Greek army
against the Turkish Muslim population of the Gemlik-Yalova peninsula.
Michael Smith adds that Circassian irregulars also took part in the massacres.
However, this is not mentioned in the report of the commission nor by Toynbee. There were 27 villages burned
and in Armutlu women were systematically raped.
Approximately 5,500 were killed
or 6.000 had disappeared at Yalova where 16 villages had been burned
The Ottoman and Turkish documents on massacres indicate that at least 9,100 Muslim Turks were killed
