Bi rce edited the twelve volumes ofThe Collected Works of Ambrose Bierce, which were published from 1909 to 1912. The seventh volume consists solely ofThe Devil's Dictionary.

Bierce has been criticized by his contemporaries and later scholars
for deliberately pursuing improbability and for his penchant toward 'trick endings'. In his later stories, apparently under the influence ofMaupassant< a>,
Bierce 'dedicated himself to shocking the audience', as if his purpose
was 'to attack the reader's smug intellectual security'.

Bierce's bias towardsNaturalism has also been noted: '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'.

Stephen Crane was of the minority of Bierce's contemporaries who valued Bierce's experimental short stories. 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 thehorror genre and some shine as great examples ofweird fiction.

Ambrose Gwinnett Bierce (June 24, 1842 - circa 1914) was an American Civil War soldier, wit, and writer.

Bierce's storyAn Occurrence at Owl Creek Bridge has been described as 'one of the most famous and frequently anthologized stories in American literature'; and his bookTales of Soldiers and Civilians (also published asIn the Midst of Life) was named by theGrolier Club as one of the 100 most influential American books printed before 1900.

A prolific and versatile writer, Bierce was regarded as one of the most influential journalists in the United States. For his horror writing,Michael Dirda ranked him alongsideEdgar Allan Poe andH.P. Lovecraft.' as a pioneering writer of realist fiction. His war stories influencedStephen Crane,Ernes Hemingway, and others, and he was considered an influential and feared literary critic. In recent decades Bierce has gained wider respect as afabulist and for his poetry.

In December 1913, Bierce traveled toChihuah a, Mexico, to gain first-hand experience of theMex can Revolution. He disappeared, and was rumored to be traveling with rebel troops. He was never seen again.

His vehemence as a critic, his motto 'Nothing matters' and the sardonic view of human nature that informed his work all earned him the nickname 'Bitter Bierce'. Despite his reputation as a searing critic, Bierce was known to encourage younger writers, including poet George Sterling and fiction writer W. C. Morrow. Bierce employed a distinctive style of writing, especially in his stories. His style often embraces an abrupt beginning, dark imagery, vague references to time, limited descriptions, impossible events and the theme of war.
