On 11 March 1895 there was an Exchange of Notes Between Great Britain and Russia. The notes defined British and Russian spheres of influence east of Lake Sari-Qul by defining the northern boundary of the Wakhan Corridor east of the lake. This boundary was subsequently demarcated by a mixed commission. The Great Game is proposed to have ended on 10 September 1895 with the signing of the Pamir Boundary Commission protocols, when the border between Afghanistan and the Russian empire was defined. The Pamir Boundary Commission was conducted by Major-General Gerard who met with a Russian deputation under General Povalo-Shveikovsky in the remote Pamir region in 1895, who were charged with demarcating the boundary between Russian and British spheres of interest from Lake Victoria eastwards to the Chinese border. The report of the Commission proved the absolute impracticality of any Russian invasion of India through the Pamir mountains. The result was that Afghanistan became a buffer state between the two powers.
