Company K

''Company K'' (1933) by William March (died 1954) is an anti-war novel composed of 113 brief, first-person vignettes told by different Marines in a single company during World War I. Based on the author's own combat experiences, it explores the brutal reality, moral horror, and psychological trauma of war, portraying it as a collective, unforgettable ordeal from training through the aftermath.

The book is a montage or collage of voices, with each chapter titled after a soldier's rank and name, creating a fast-paced effect. March shuns romanticized war stories, focusing instead on themes of lost innocence, fear, cowardice, and the senseless nature of "mass-produced death".

It heavily covers the moral injury of war, including incidents of soldiers executing German prisoners, highlighting the moral degradation of the combatants.
The vignettes go beyond the battlefields of France to show the lingering trauma of survivors attempting to adjust to normal life.

Written by a highly decorated Marine, the book is considered a protest against the brutality of war and is often lauded for its unvarnished, "bare" prose.
