Stephen Crane 
The Red Badge of Courage (Centaur Classics) [The 100 greatest novels of all time – #57] 

‘If there were in existence any books of a similar character, one could start confidently by saying that it was the best of its kind. But it has no fellows. It is a book outside of all classification. So unlike anything else is it that the temptation rises to deny that it is a book at all.’ —Harold Frederic
‘A masterpiece.’ —George Wyndham
‘[‘The Red Badge of Courage’] is one of the finest books of our literature, and I include it entire because it is all as much of a piece as a great poem is.’ —Ernest Hemingway

First published in 1895, this small masterpiece set the pattern for the treatment of war in modern fiction. The novel is told through the eyes of Henry Fleming, a young soldier caught up in an unnamed Civil War battle who is motivated not by the unselfish heroism of conventional war stories, but by fear, cowardice, and finally, egotism. However, in his struggle to find reality amid the nightmarish chaos of war, the young soldier also discovers courage, humility, and perhaps, wisdom. Although Crane had never been in battle before writing The Red Badge of Courage, the book was widely praised by experienced soldiers for its uncanny re-creation of the sights, sounds, and sense of actual combat. Its publication brought Crane immediate international fame and established him as a major American writer. Today, nearly a century later, the book ranks as an enduring landmark of American fiction.
