I bought this for the story "An Occurrence at Owl Creek Bridge" which I'd heard was famous but had never read at school. I already knew of Bierce from his extremely sarcastic Devil's Dictionary.
So far have only read "Occurrence..." which I liked and would recommend.

Mr. Bierce is one of the jewels of American Literature . These are the short stories and some of his journalism on the topic of the great American Trauma. More romantic than the man revealed in the "Devil's Dictionary". ( )

This is a compilation of macabre short stories about the Civil War by the inimitable Ambrose Bierce, himself a veteran of the conflict. The most famous of these is undoubtedly "An Occurrence at Owl Creek Bridge". This was made into a French film which won first prize for short subjects at the 1962 Cannes Film Festival and appeared as the very last episode of The Twilight Zone on 2/28/64. It also won the 1964 Oscar for best short subject. Another story which may be familiar is "Parker Adderson, Philosopher", which was filmed in 1974. ( )
