The Middle Parts of Fortune is a novel by Frederic Manning that depicts the experiences of ordinary British soldiers, particularly Private Bourne, fighting in the trenches of World War I.

Primarily focused on the brutal realities of the Battle of the Somme, including the trauma, camaraderie, boredom, and moments of bloodlust they faced, the book has been praised, since its publication in 1929, for its authenticity and raw depiction of war's psychological impact.
