As a result of the Bolshevik aggression, the government of the Ukrainian People's Republic that initially pursued anti-military policy sought military support after the capital Kyiv was sacked on 9 January 1918, by Mikhail Muravyov. On 9 February, Ukraine signed the Treaty of Brest-Litovsk with the coalition of Central Powers and by March all Bolshevik forces of the Russian SFSR were removed from the territory of Ukraine. The German Army Group Kyiv was created in order to protect Ukraine from further Bolshevik aggression and headed by the German Field Marshal Hermann von Eichhorn.
