During his lifetime, Bierce was better known as a journalist than as a fiction writer. His most popular stories were written in rapid succession between 1888 and 1891, in what was characterized as "a tremendous burst of consummate art".[34] Bierce's works often highlight the inscrutability of the universe and the absurdity of death.[35][36]
Bierce wrote realistically of the terrible things he had seen in the war[37] in such stories as "An Occurrence at Owl Creek Bridge", "A Horseman in the Sky", "One of the Missing", and "Chickamauga". His grimly realistic cycle of 25 war stories has been called "the greatest anti-war document in American literature". To the end of his life, nothing would so infuriate him as hearing accounts of the honor and glory of war from people who'd never seen or experienced it personally.[38]
According to Milton Subotsky, Bierce helped pioneer the psychological horror story.[39] In addition to his ghost and war stories, he also published several volumes of poetry. His Fantastic Fables anticipated the ironic style of grotesquerie that became a more common genre in the 20th century.
One of Bierce's most famous works is his much-quoted The Devil's Dictionary, originally an occasional newspaper item, first published in book form in 1906 as The Cynic's Word Book. Described as "howlingly funny",[40] it consists of satirical definitions of English words which lampoon cant and political double-talk. Bierce edited the twelve volumes of The Collected Works of Ambrose Bierce, which were published from 1909 to 1912. The seventh volume consists solely of The Devil's Dictionary.
Bierce has been criticized by his contemporaries and later scholars for deliberately pursuing improbability and for his penchant toward "trick endings".[35] In his later stories, apparently under the influence of Maupassant, Bierce "dedicated himself to shocking the audience", as if his purpose was "to attack the reader's smug intellectual security".[41]
Bierce's bias towards Naturalism has also been noted:[42] "The biting, deriding quality of his satire, unbalanced by any compassion for his targets, was often taken as petty meanness, showing contempt for humanity and an intolerance to the point of merciless cruelty".[43]
Stephen Crane was of the minority of Bierce's contemporaries who valued Bierce's experimental short stories.[44] In his essay "Supernatural Horror in Literature", H. P. Lovecraft characterized Bierce's fictional work as "grim and savage." Lovecraft goes on to say that nearly all of Bierce's stories are of the horror genre and some shine as great examples of weird fiction.[45]
Critic and novelist William Dean Howells said, "Mr. Bierce is among our three greatest writers." When told this, Bierce responded, "I am sure Mr. Howells is the other two."[46]
