On 1918, the same the day Bolshevik forces captured Kiev, the Central Rada signed the
Peace of Brest with the Central Powers. In cooperation with the UPR military, the Rada allowed the German and Austro-Hungarian forces to occupy Ukraine, which began a few days later. The Soviet forces panicked as soon as they heard of the Central Powers' intervention, and all Bolshevik government and party organisations immediately began evacuating eastwards in a hurry. The Soviet leadership fled from Kiev towards
Poltava around 11/24 February, and one week later on 1918, the Central Powers and UPR troops entered Kiev. The Soviets had only been in control of the capital for 20 days, and did not even offer token resistance to the Central Powers as they chaotically retreated.
Ukrainian People's Army forces under
Symon Petliura, along with
German and
Austro-Hungarian troops, would retake Kiev on 1 March. The Bolshevik government
recognized Ukraine's independence on 3 March. Meanwhile, the Bolsheviks attempted to regroup in eastern Ukraine. The new situation caused disagreements between the various Soviet factions. The expelled left-leaning Kievan Bolsheviks sought to ally themselves with the peasant masses and engage in partisan guerrilla warfare without Russian help, and urged on their communist comrades in Kharkiv to try and retake the capital from the Rada, Germans and Austro-Hungarians. However, the right-leaning Kharkiv and Katerynoslav (Dnipro) Bolsheviks expressed separatist tendencies, striving to break with Kiev and rather "join the Russian federation" for various socio-economic and political reasons, arguing that the rest of Ukraine lacked an industrialised proletariat, and that complete subordination to the central communist party organs in Moscow was necessary. These internal divisions within the Ukrainian communist movement weakened their overall capabilities. The left-wing faction would prevail for the time being at the
Second All-Ukrainian Congress of Soviets in Katerynoslav on 17–19 March 1918, where it was decided that all of Ukraine would be united in a single Ukrainian Soviet Republic, separate from Soviet Russia, with its own separate communist party. However, just a few weeks later in April, the Central Powers and UPR troops expelled all Bolshevik forces from the remaining territory of Ukraine, forcing them to flee to Moscow after all. Subsequently, during May to October 1918,
peace negotiations were held between Soviet Russia and Ukraine. ==Order of battle==
