What were the main causes of the Bolshevik success in the Russian Civil War?

White Army weaknesses:Disunited and quarrelsome (no united goal or leader)Organisation of directory (coalition) lasted 2 months : Sept-Nov 1918Kolchak unable to establish an understanding with the allies, Czech's or SR's (different goals), led to a retreat as they were too weak as a unit (after reaching Perm and Ufa March 1919)Geographical separation = poor communicationEconomically weak due to WW1 Voluntary army (unskilled)Failed to capture hearts and minds of peasants who saw them as invaders rather than humanitarians
Red Army Strength Trotsky's leadership and organisation of commanders such as Frunze led to the tackling of opposition and success at OmskCoherent policy (stay in power and spread communist influence)Rigid structure and hierarchy (one central leader - Trotsky appointed by Lenin)Better supplied (seized control of the trans-Siberian railway, can carry personnel across inhabitable areas)Occupied capital = geographic advantage/centralised power (Moscow)Red army soldiers were professionally trained (retained expertise from Sino-Japanese war and Crimean war)
