At Brest-Litovsk Trotsky shocked the Germans by rejecting their harsh peace terms but then informing them that Russia will fight them no more. The Bolsheviks hope that this ‘No War, No Peace‘ strategy will expose the Germans as naked aggressors if their army resumes its advance in the east, triggering revolution from Germany’s war weary working class.
Ludendorff is Germany’s Quartermaster General and the effective dictator of his country. He does not care about being seen as a naked aggressor; he wants the war in the East brought to an end as soon as possible so that he can concentrate his efforts on the Western Front offensive he is planning. Today German and Austro-Hungarian troops launch Operation Faustschlag, an offensive intended to force the Russians to sign the peace treaty. They encounter no meaningful resistance; by now the old Tsarist army has been disbanded and the recently established Red Army is in no position to take the field against the Kaiser‘s juggernaut. The Germans and their allies advance at a speed that would be unimaginable on the Western Front.
