The story concerns a decorated English military hero, Lord Arthur Scoresby, a total idiot who triumphs in life through good luck. At the time of the Crimean War Scoresby is a captain. Despite his complete incompetence, everyone misinterprets his performance, taking his blunders for military genius, and his reputation is enhanced with every false step he makes. At the climax of the story, Scoresby mistakes his right hand for his left and leads a charge in the wrong direction, surprising a Russian force which panics and causes a retreat of the Russian army, thus securing an Allied victory.
