The 1920s saw the so-called "war book boom," during which many men who had fought during the war were finally ready to write openly and critically about their war experiences. In 1929, Erich Maria Remarque's "All Quiet on the Western Front" was a massive, worldwide bestseller. Also significant were Ernest Hemingway's "A Farewell to Arms" (1929), Richard Aldington's "Death of a Hero" (1929), Arnold Zweig's "The Case of Sergeant Grischa" (1927), Charles Yale Harrison's "Generals Die in Bed" (1930) and William March's "Company K" (1933).
