The answer to this question is:
German U-boat U-571 is immobilized by a British destroyer. The US Navy submarine S-33 has been modified to resemble a German U-boat to steal the Enigma coding device and sink the U-571.During a storm, the S-33 comes across U-571 and sends a boarding party over. After securing the ship and transporting the captured crew back to the American S-33 sub, the S-33 gets sunk by the arrival of a German resupply sub. The captain of the S-33, Lieutenant Commander Dahlgren, dying in the water, orders his men on the captured U-boat to submerge. Lieutenant Tyler takes command of the enemy U-boat and dives to engage the resupply sub in an underwater battle before destroying it.After making repairs and restoring power Tyler decides to route the disabled submarine to Land's End in Cornwall, England.

The sub dives underneath the German ship, which then begins to drop depth charges to sink U-571.Tyler attempts to trick the destroyer into stopping its attack by ejecting debris and a corpse out of a torpedo tube, faking their own destruction. The German destroyer continues dropping depth charges. U-571, hiding at below 600 feet (180 m), is damaged by the high water pressure. Control of the main ballast tanks is lost and the ship ascends uncontrollably. Tyler orders crewman Trigger to submerse himself in the bilge underwater to repressurize the torpedo tubes.Trigger uses an air hose to enter the flooded compartment. He closes the air valve to the torpedo tubes, but a second leak and broken valve are found, which Trigger can't reach. U-571 surfaces, unable to fire its last torpedo. The destroyer fires on the ship, which is heavily damaged and...
