Bierce was a decorated Civil War vet himself, and was infuriated by the white-washing and glorification of the war from both sides afterwards. His war writing will feel very modern in its sarcastic tones and brutal descriptions. You might have read "Incident on the Owl Creek Bridge" in high school, but there are a lot of other revealing portraits and stories as well, some desperately sad and some vicious with satire and bitterly funny. I wouldn't necessarily recommend blasting through all 300 pages in one sitting -- the tone can ultimately get a bit repetitive -- but as a companion to historical readings of the Civil War, or simply as a way to discover one of the great American soldier/writers, this is an extremely good collection, with ample notes and explanations when needed.
