The Army of Islam, under the control of Nuri Pasha, moved forward and attacked Australian, New Zealand, British, and Canadian troops led by General Lionel Charles Dunsterville at Baku. General Dunsterville ordered the evacuation of the city on 14 September, after six weeks of occupation, and withdrew to Iran. As the Army of Islam and their Azerbaijani allies entered the city on September 15 following the Battle of Baku, up to 30,000 Armenian civilians were massacred.
