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. Tyler attempts to deceive the destroyer into stopping its attack, by ejecting debris and a dead crew member out of a torpedo tube, faking their own destruction. However, the destroyer continues to drop depth charges. U-571 drops below , and is damaged by high water pressure. They start to sink, and can only reverse this by ascending uncontrollably. Tyler orders crewman Trigger to submerge himself in the bilge under water to repressurize the single remaining torpedo tube. Trigger uses an air hose to breathe inside the flooded compartment. He closes the air valve to the stern tube, but finds a second leak, which he can't reach. The crew realizes that Wassner, despite being shackled, is using Morse Code to tap out a signal that the submarine had been captured, so Hirsch kills him. U-571 surfaces heavily damaged and begins to flood, unable to fire its last torpedo. The pursuing destroyer fires with its main guns: the damage pins Trigger's legs when he is beyond reach of the air hose. Unable to turn back, he manages to close the valve just before he drowns. Tyler orders Tank to fire the torpedo; the destroyer is unable to take evasive action and is sunk. As the crew sighs in relief, Tank reports Trigger's death. However, the submarine has taken severe damage, and so the crew abandons it with the Enigma in their possession. They watch U-571 as it slips beneath the waves once and for all. They are eventually spotted and rescued from their lifeboat by a US Navy PBY Catalina flying boat.
