In January and again in February, Lenin urged the Bolsheviks to accept Germany's proposals. He argued that the territorial losses were acceptable if it ensured the survival of the Bolshevik-led government. The majority of Bolsheviks rejected his position, hoping to prolong the armistice and call Germany's bluff. On 18 February, the German Army launched Operation Faustschlag, advancing further into Russian-controlled territory and conquering Dvinsk within a day. At this point, Lenin finally convinced a small majority of the Bolshevik Central Committee to accept the Central Powers' demands. On 23 February, the Central Powers issued a new ultimatum: Russia had to recognise German control not only of Poland and the Baltic states but also of Ukraine, or face a full-scale invasion.
