In 1919, the troops of the Main Command 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 Main Command 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. Several trial impressions were made of a new typographic overprint in four lines, 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 Main Command of the Armed Forces of South Russia, overprinted "100 rubles" on 1 kopek, perforated and imperforate, were issued after the evacuation of the White forces from Crimea on November 11, 1920.
