At the time that General Kaufmann sheathed his sword under the influence of the Treaty of Berlin, in 1878, there remained another representative of Russia--General Stolietoff--who had been quietly negotiating with the Ameer of Afghanistan, Shere Ali, the terms of a "Russian treaty," whose characteristics have already been described. Hearing of this, the English Ambassador at St. Petersburg questioned the Russian Minister, who answered him "that no mission had been, nor was intended to be, sent to Kabul, either by the Imperial Government or by General Kaufmann." This denial was given on July 3d, the day after Stolietoff and his mission had started from Samarcand. After the envoy's arrival at Kabul, another remonstrance met with the reply that the mission was "of a professional nature and one of simple courtesy," and was not, therefore, inconsistent with the pacific assurances already given. The real nature of this mission became known from papers found by General Roberts at Kabul in 1879. These showed that Shere Ali had been invited to form a close alliance with the Russian Government. General Kaufmann had advised Shere Ali to try and stir up disaffection among the Queen's Indian subjects, promising to aid him, eventually, with troops. Finding that this scheme was impracticable at the moment, Russia dropped the Ameer, who fled from the scene of his misfortunes, and died soon after. For the moment England breathed more freely. There were still great natural obstacles between the empires of Russia and of India. Not only the friendly state of Afghanistan, but on its northwestern border the neutral territory of Merv, hitherto an independent province, and inhabited by warlike tribes of Turcomans difficult to reach through their deserts and likely to harass a Russian advance to Herat to an embarrassing extent. It was seen that the possession of this territory would at once free Russia from much difficulty in case of an advance and give her the means of threatening Herat as well as Kabul from her base in Turkestan, and even to some extent to carry forward that base beyond the Oxus. On the part of Russia, the success of General Skobeleff in capturing the fortified position of Geok Tepe, January 24, 1880, marked the beginning of negotiations with the Turcomans for the acquisition of Merv. For a long while these were unsuccessful, but early in 1884 it was cabled to London, that "The Queen of the World" had accepted the White Czar as her future liege lord.
