On 20 November 1918, an issue of eight postage stamps was produced by applying typographic surcharges with new denomination numerals to stamps of the 17th and 21st issues of the Russian Empire. The overprints were made in Rostov-on-Don. The stamps remained in postal circulation within the Don Region until their official withdrawal on 15 July 1919.
In October 1918, a decree of the Great Host Circle followed on the "de-Cossackization" of all Cossacks who at the front had gone over to the side of the Red Army. In total, during the Krasnov regime, that is, from May 1918 to February 1919, at least 45,000 supporters of Soviet power on the Don were brutally exterminated. In October 1917, even before Soviet power was established, Krasnov actively supported Kaledin's act of separating the Don from Russia and the formation, under the aegis of the Don White Cossacks, of the South-Eastern Union (the Don, Kuban, Terek, the mountain peoples of the North Caucasus, and the Stavropol region), which opposed the Center. This gave a powerful impulse to the breakup of Russia as a single state. And in 1918, having come to power on the Don, Krasnov proclaimed the creation of an independent Don Republic and, with renewed energy, set about forging a bloc hostile to Soviet Russia under the name "Don-Caucasian Union."
