"STEPHEN CRANE CONVEYED WAR’S HORROR, EXISTENTIAL ANGST LIKE NO OTHER"

From the Internet webzine "Coffee or Die": OPINION & ESSAY By J.E. McCollough | 

"Stephen Crane wrote about war long before he ever saw combat as a journalist. Crane was born after the Civil War, and despite never having pulled a trigger in that conflict, he wrote vivid prose in The Red Badge of Courage about combat he hadn’t seen. The novella was a plotless narrative of a single soldier’s [Henry Fleming] humiliating cowardice and eventual redemption in the Civil War. It made Crane internationally famous in 1895 because he wrote so viscerally readers thought he must be a combat veteran."

Indeed! While a schoolboy in grammar school [primary education] I very well remember reading the "Red Badge of Courage" and absolutely thinking that events as described in the novella the more or less personal experience and account of Crane himself. Crane was Fleming and Fleming was Crane. But this was just not so!

Also indeed the cinematic version of "Red Badge" having in the lead role Audie Murphy. The most decorated [?] American war hero of World War Two. See the movie trailer at the IMDB web site.
