The Inter-Allied commission, consisting of British, French, American and Italian officers, and the representative of the Geneva International Red Cross, M. Gehri, prepared two separate collaborative reports on their investigations of the Gemlik-Yalova Peninsula Massacres. These reports found that Greek forces committed systematic atrocities against the Turkish inhabitants. And the commissioners mentioned the "burning and looting of Turkish villages", the "explosion of violence of Greeks and Armenians against the Turks", and "a systematic plan of destruction and extinction of the Moslem population". In their report of the 23rd May 1921, the Inter-Allied commission stated also that "This plan is being carried out by Greek and Armenian bands, which appear to operate under Greek instructions and sometimes even with the assistance of detachments of regular troops". The Inter-Allied commission also stated that the destruction of villages and the disappearance of the Muslim population might have as its objective to create in this region a political situation favourable to the Greek Government. The Allied investigation also pointed that the specific events were reprisals for the general Turkish oppression of the past years and especially for the Turkish atrocities committed in the Marmara region one year before when several Greek villages had been burned and thousands of Greeks massacred.
