Therefore, on 18 February 1918, the Germans began Operation Faustschlag on the Eastern Front, encountering virtually no resistance in a campaign that lasted 11 days. Signing a formal peace treaty was the only option in the eyes of the Bolsheviks because the Russian Army was demobilized, and the newly-formed Red Guard could not stop the advance. They also understood that the impending counterrevolutionary resistance was more dangerous than the concessions of the treaty, which Lenin viewed as temporary in the light of aspirations for a world revolution. The Soviets acceded to a peace treaty, and the formal agreement, the Treaty of Brest-Litovsk, was ratified on 3 March. The Soviets viewed the treaty as merely a necessary and expedient means to end the war.
