Mirbach took part in the Soviet-German peace negotiations at Brest-Litovsk (December 1917 to March 1918). In April 1918 he was appointed German ambassador to the government of the RSFSR in Moscow. He was killed by the Left Socialist Revolutionary la. G. Bliumkin on instructions from the Central Committee of the party of the Left Socialist Revolutionaries who attempted to provoke a war with Germany. Mirbach’s murder served as the signal for the outbreak of the Left Socialist-Revolutionary revolt in Moscow in 1918.
