Since April 1918, the city of Baku had been governed by a
Soviet (council) under the leadership of the
Bolshevik Stepan Shahumyan. The Baku
Sovnarkom or Soviet had been collaborating with the local branch of the Armenian
Dashnaktsutiun party to establish control over the city and its surrounding environs but by the beginning of the summer of that year, it found itself under increasing threat by the advancing armies of the
Ottoman Empire. The armed forces of the two sides clashed in June and July but the forces loyal to the Baku Soviet were unable to halt the joint Ottoman-
Azerbaijani offensive and were forced to retreat. With the Ottomans and Azeris poised to strike Baku and with no promise of material support from
Moscow, the Baku Soviet was forced to turn to a
British expeditionary force which was stationed in the region under the command of Major General
Lionel C. Dunsterville. Although Shahumyan was under orders from Moscow to deny entry to the British, he was overruled by his peers in the Soviet, who formally requested British help in late July. On July 31, Shahumyan and the other Bolshevik members of the Baku Sovnarkom resigned from their posts and control of the city was assumed by the
Centro-Caspian Dictatorship. In August, the Ottoman military, led by the
Army of Islam, launched a new assault against the frontline positions, which were primarily manned by Armenians. Despite some initial victories, the Armenians had to retreat. The size of the British expeditionary force had proved ultimately to be too small to make much of an impact in the
defense of Baku. In the first week of September, a joint Ottoman-Azerbaijani force composed of 15,000 men advanced without much resistance toward Baku and by September 13, had reached the suburbs of the city; meanwhile, Baku's Muslim population prepared to welcome the entry of the Ottoman army. The remaining Armenian troops were too ill-prepared to halt the advance and Dunsterville refused to retain his force any longer. On September 14 his force evacuated from Baku and sailed to
Enzeli, leaving the city virtually defenseless. ==Events of September Days==
