After making repairs and restoring its power, Tyler decides to route the disabled submarine toward Land's End in Cornwall. However, they are spotted by a German reconnaissance plane, which is unaware that "U-571" has been commandeered by Americans. A nearby German destroyer sends over some crew, but before they arrive, Tyler gives orders to fire a shot from the deck gun, which destroys the ship's radio room, preventing it from reporting the situation and revealing that the Allies have the Enigma. The submarine then dives beneath the German destroyer, which begins to drop depth charges. "U-571's" "Kapitänleutnant" Wassner escapes captivity, and kills one of Tyler's crew, but he is subdued before he can sabotage the engines.
