In 1936, a Nazi sergeant was among the German forces carried aboard the U-boat Wurrfler, serving under Colonel Herman Dietrich following the Nazi excavation for the Ark of the Covenant at Tanis outside Cairo, Egypt.
Following American archaeologist Indiana Jones and bar owner Marion Ravenwood's interference and claiming the Ark, the two were to be ferried to England by pirates led by Captain Simon Katanga aboard the Bantu Wind. However, the Nazis intercepted them in the Mediterranean Sea and sent a boarding party onto the ship, the sergeant among them.
The Nazis held Captain Katanga and his crew at gunpoint as they searched the vessel for the artifact in addition to Jones and Ravenwood. The sergeant led two men below deck, where they found Marion. Ravenwood angrily told the sergeant not to touch her, but he ignored her and brought her to the main deck with the Ark. When Marion saw Dietrich, she attempted to slap him, but Katanga pulled held her back, much to the amusement of the pirates.
Dietrich questioned the whereabouts of Jones to which another man responded that there was no trace of him. Katanga protected the archaeologist, hiding in a nearby vent, by saying that he had killed Jones. The Nazis, including the sergeant, then returned to the Wurrfler with Marion and the Ark, and headed for Geheimhaven.
Behind the scenes
In the third draft of the film's script, written by Lawrence Kasdan, the Sergeant had a speaking role, saying "Not a trace yet, sir!" after Colonel Shliemann (Dietrich's original name in the script) asks if the soldiers have found Jones. Although this line is preserved in the film, another Nazi soldier says it. The comic book adaptation likewise has him saying the aforementioned line in place of the soldier from the film.
