Subsequently, in South Russia, a mission of 10 officers and 55 other ranks of the British Royal Tank Corps trained more than 200 volunteer officers of the Armed Forces of South Russia
(AFSR) at the Russian Tank School (Opportunities for the deployment of tanks by anti-Bolshevik forces in North Russia were limited by the forested and swampy terrain, but a North Russian Tank Detachment (of four Mark Vs and two Mark Bs), under Major J. N. L. Ryan, was formed at Arkhangel′sk on 11 August 1919, to fight alongside the Whites’ Northern Army
. Three of the tanks were deployed alongside an armored train on the Vologda railway on 29 August 1919, and 34 officers and men of the North Russian Tank Corps were trained by Bryan at his headquarters at Solombala, before the final British evacuation of Arkhangel′sk on 27 September 1919. Two British tanks were left behind for the Russians and saw action in October against Red forces around Plestetskaia station. On 19 February 1920, as Red forces entered Arkhangel′sk, their crews loaded the tanks onto barges and sank them in the Dvina River. They were subsequently salvaged by the Reds and sent to Moscow for analysis.The British North-West Russian Tank Detachment, comprising 22 officers, 26 men, and 6 Mark V (composite) tanks, under Lieutenant Colonel E. Hope-Carson, arrived at Revel (Tallinn) starting on 6 August 1919. They saw action in the Narva region during the advance toward Petrograd of the Whites’ North-West Army
in September–October 1919 and were used to train 22 officers and 9 enlisted men of the Russian Tank Battalion. On 18–25 October 1919, the tanks were deployed at Gatchina and Tsarskoe Selo, alongside three Russian-crewed Renault FT-17s that had been loaned by Finland. When the White forces retreated, the tanks were entrained and sent back to Revel. The Finnish tanks were returned to Helsinki, and the British tanks were given to the Estonian Army.
