Congress made a decision to get a close alliance with Russian Republic (also Soviet) and elected Central Executive Committee (Ukrainian: ЦВК).

It was reformed on March 19, 1918, at the Second All-Ukrainian Congress of Soviets in Yekaterinoslav, following the signing of the Treaty of Brest-Litovsk by the Russian Soviet Federative Socialist Republic (Russian SFSR) on March 3.

Military forces of Soviet government of Ukrainian Republic of that time are known as Red Cossacks Army, later integral part of Red Army of the Soviet Union.

It was soon overrun, however, by forces of the Central Powers and the Ukrainian People's Republic.

On April 18, 1918, in Taganrog,[1] the next session of the Central Executive Committee of Soviets announced that the government of Soviet Ukraine, the Central Executive Committee of Ukraine and the People's Secretariat were now combined as the "Ukrainian Bureau" to guide the insurgent struggle against the German occupation.
