During World War I, U-96 was launched on February 15, 1917, and commissioned into the Kaiserliche Marine on April 11, 1917.
U-96 conducted 11 patrols, sinking 28 ships totalling 190,094 tons and damaging four others totalling 33,043 tons. On March 30, 1945, U-96 was sunk by US bombs while in the submarine pens in Wilhelmshaven. In her entire career, U-96 suffered no casualties to her crew.
During 1941, a war correspondent named Lothar-Günther Buchheim joined U-96 for a single patrol. His orders were to photograph and describe the U-boat in action for propaganda purposes. From his experiences, he wrote a short story, "Die Eichenlaubfahrt" ("The Oak-Leaves Patrol") and a novel which was to become an international best-seller, Das Boot.
