Bierce authored “The Devils Dictionary”. He was an author whose service as a major in American Civil War greatly impacted his view of mankind...it wasn’t favorable. He also was one of the very few people who wrote about a serviceman killing a comrade to put him out of his misery.
I haven’t read Bierce in a long time, but for $1.99 I’ll take a flyer on this for kindle:
“Ambrose Bierce: Complete Collection of Works with analysis and historical background (Annotated and Illustrated) (Annotated Classics)”
