The Group of Forces for Combating Counter-Revolution in the South of Russia (Russian: Группа войск по борьбе с контрреволюцией на Юге России|translit=Gruppa voysk po bor'be s kontrrevolyutsiyey na Yuge Rossii) was a military formation of the Soviet Russian government created in the beginning of December 1917 to invade and occupy various autonomous state formations (the Don Host Oblast and Ukrainian People's Republic) with a goal of establishing the Soviet government.
The formation mainly consisted of Red Guard troops from Petrograd and Moscow under the command of Vladimir Antonov-Ovseenko and Mikhail Muravyov as the chief of staff. The group consisted of some 20,000 troops.
The group started to arrive in Kharkiv on December 21, 1917, and on December 22–23, 1917, with the help of the local squads of Red Guards, it established Soviet power in the city. On December 24–25, 1917, in Kharkiv the First All-Ukrainian Congress of Soviets, which proclaimed the Ukrainian People's Republic of Soviets, took place. The group included the squads of Rudolf Sivers, Yuriy Sablin, Pavel Yegorov, Grigory Petrov, and others, as well as the local squads of Red Guards.
In the beginning of January 1918, without any official declaration of war, the group initiated military actions around Kharkiv (Lozova, Synelnykove, Pavlohrad, Sloviansk). By that time the Soviet government of Russia had concluded a provisional armistice agreement with the Central Powers, seeking to end its participation in World War I (see Treaty of Brest-Litovsk). On January 2, 1918, Sovnarkom appointed Sergo Ordzhonikidze the provisional extraordinary commissar of the Ukrainian region, who arrived in Kharkiv on January 8. In January 1918, under the pretense of helping the Bolsheviks of Ukraine in establishing Soviet power, the group launched an offensive from multiple directions (Kharkiv and Katerynoslav, Bryansk, Homel) against Kiev. A cover for military actions against the Ukrainian People's Republic was a call of the People's Secretariat to an armed struggle against the "counter-revolutionary" Central Council of Ukraine. The command of the offensive was handed to the acting People's Commissar Yuri Kotsiubynsky (acting for Vasyl Shakhrai). On February 8, 1918, the group occupied Kiev and the government of Ukraine relocated to Zhytomyr. On February 9, 1918, it signed a military protection pact with the Central Powers (see Treaty of Brest-Litovsk (Ukraine–Central Powers)).
In the east the group managed to occupy the Donets basin and the territory of the Don Host Oblast, ending the authority of General Alexey Kaledin. In the occupied territories such political formations as the Don Soviet Republic and the Donetsk-Krivoi Rog Soviet Republic were established.
On January 15, 1918, the formation occupied Oleksandrivsk (Zaporizhia), and on January 21, 1918, Kharkiv received a message from Katerynoslav: "Pass this on to the Red Guard headquarters. We attacked Poltava ... the station is occupied, there is fighting in the city. Send urgently to Konstantinograd (Krasnohrad) 1000 Red Guards to connect with Yegorov". The Moscow Red Guard squads led by Yegorov, while traveling from the Lozova Rail Station, intercepted a heavy siege battery of the opponent that was sent to Poltava from Novocherkassk. At the same time Vladimir Antonov-Ovseenko reported to the Narkom of Military Affairs (Soviet Russia): "Yesterday in the evening Poltava was occupied by us through an offensive from Lozova and Kharkiv... [We are] anticipating a report about the occupation of Bakhmach".
On January 28 the 1st Minsk Revolutionary Troops, led by Reingold Berzin, occupied Bakhmach. Bērziņš's unit consisted of 3,500 Red Guards and soldiers, four artillery batteries, and an armored train (Putilov plant) with a team of 77 people and 16 machine guns. The same day, the revolutionary forces met some resistance at the Kruty Rail Station, where they were held off for another day by a few hundred cadets. Another commander of the Moscow Red Guards was Andrei Znamensky, who led the special assignment unit of Blagushe-Lefortovo.
At the Extraordinary All-Russian Railway Congress on January 26, 1918, Vladimir Lenin stated that the Rada was "living out its last days". On January 29 in Kiev an uprising of workers started at the Arsenal city factory. To their help rushed the squads of P. Yegorov, G. Kudinsky, Vitaliy Primakov, Reingold Berzin and others. In the fierce fighting on the outskirts of Kiev and in the city, artillery and armored trains were widely used. On February 6, 1918, the command of the Soviet forces reported back to Lenin in Petrograd that street fighting was taking place in Kiev and the Red Guards were suffering great losses. And it further stated: "We have cleared all the stations in Kiev, as well as the Rail Terminal. Armored trains of the latest technology are pushing out the enemy from the city center. Our artillery is shelling the city day and night. Request urgently that 1,000 Red Guards be sent." But no reinforcements were really needed, as the Ukrainian forces withdrew from the city. On February 8, 1918, Kiev finally became Soviet.
With the situation in Ukraine and the Lower Don river region secured, the group of forces was redirected to the South Ural region against General Alexander Dutov and then Józef Dowbor-Muśnicki in the eastern regions of Belarus.
