Providing a full account of Trotsky's role during the Russian Civil War and concentrating on his time as an active participant in Russian revolutionary politics, rather than his ideological writings of emigration, Swain gives a very different picture of the Bolshevik Commissar of War. This radically new interpretation of Trotsky's career spanning 1905-1917 incorporates the tense relationship between Trotsky and Lenin until 1917, and pays particular attention to the Russian Civil War and Trotsky's military organisation and contribution to the war.
