local Muslims of up to "ten thousand well-armed men". The British sympathy to the Aras Republic was later reversed when Major-General William M. Thomson became the highest-ranking officer in the South Caucasus—believing that Pan-Turkism was influential in the region, especially in consideration of the presence of Azerbaijani and Ottoman agents Samed Bey and Colonel Halil Bey, respectively. Thomson believed that they were scheming to "forge a bridge between the Ottoman Empire and Azerbaijan and ultimately between Nationalist Turkey and Soviet Russia." Following the British announcement of the dissolution of the governorship and the plans to annex the region to Armenia, was selected to become the first governor of the district. Armenia's formal annexation of Nakhichevan was officially declared on 3 May 1919, after which Armenian forces commanded by Drastamat Kanayan and accompanied by British representative General K. M. Davie advanced southward into the district along the railway. When the force had reached Davalu (present-day Ararat), Thomson ordered them to stop, believing that Armenia was encouraging the defiance of Zangezur in refusing to submit to British–Azerbaijani authority in a "severe breach of faith". The restriction Thomson had placed was later revoked after acting prime minister Alexander Khatisian met him in Tiflis to assure him that the Armenians of Zangezur were acting independently of the Armenian government. On 13 May 1919, when Armenian forces had advanced to Bashnorashen (present-day Sharur), Khatisian arrived in Nakhichevan and met the minister of war of the Aras Republic, , after which the Aras Republic effectively capitulated. Anti-Armenian uprising Despite the apparent defeat of the Ottoman Empire, agents of the Turkish National Movement were reported to be fostering rebellion amongst the Muslims of Nakhichevan, eventually culminating in a large-scale anti-Armenian uprising in July 1919. Fearing retaliation by the Volunteer Army, Azerbaijan did not openly intervene to assist the Nakhichevan rebels, however, on 14 July they provided covert assistance. On 20 July, a pogrom began against the Armenian inhabitants of the city of Nakhichevan—within a few days, the Armenian administration was completely ousted and its Armenian inhabitants expelled. As the uprising spread throughout the Nakhichevan uezd, Armenians in Jugha (present-day Gülüstan) were forced to escape across the Aras river into Iran. Some 6,000 Armenians from Nakhichevan living in the Ararat Valley managed to escape to Daralayaz, Nor Bayazet, and Zangezur (present-day Vayots Dzor, Gegharkunik and Syunik provinces, respectively). During the uprising, Halil Bey coordinated the destruction of 45
