The Jungle movement that had started in 1914 gained momentum after the victory of the Bolsheviks in Russia. In May 1920 the Soviet Caspian Fleet, led by Fedor Raskolnikov and accompanied by Sergo Orzhonikidze, entered the Caspian port of Anzali. This mission was declared to be only in pursuit of the Russian vessels and ammunition taken to Anzali by the White Russian counter-revolutionary General Denikin, who had been given asylum by British forces in Anzali. The British garrison in Anzali soon evacuated the town without any resistance, retreating to Manjil.
