In 1919, the troops of the Armed Forces of South Russia (generals A. Denikin and P. Wrangel) occupied Left-Bank Ukraine and Crimea. In August–October 1920, the administration of General P. Wrangel in Crimea carried out the 4th issue of stamps of the Armed Forces of South Russia.
In early October 1920, the question was raised of increasing postal rates and revaluing the remaining stocks of stamps. In connection with this, several trial impressions were made of a new four-line typographic overprint in black ink with the words "South of Russia", the value figure, and the word "rubles" on Russian stamps of the 17th and 21st issues. Two stamps of the fifth issue of the Armed Forces of South Russia with the overprint "100 rubles" on 1 kopek, perforated and imperforate, were released after the evacuation of the White forces from Crimea on 11 November 1920.
