The Great War, 'The war to end all wars' as someone optimistically called it, had ended on 11 November 1918. Forgotten Valour is the story of Arthur Sullivan VC and other Australian soldiers who enlisted in the Great War but went on to fight in the Russian Civil War. The story focuses on Corporal Arthur Percy Sullivan, a 22-year-old soldier from South Australia, who was amongst the column of men pinned down in the muddy waters of Russia while bullets whistled past them. What happened went on to change his life and earn him the Victoria Cross.
