U-571 is a 2000 submarine film directed by Jonathan Mostow from a screenplay he co-wrote with Sam Montgomery and David Ayer. The film stars Matthew McConaughey, Bill Paxton, Harvey Keitel, Jon Bon Jovi, Jake Weber and Matthew Settle. The film follows a World War II German submarine boarded by American submariners to capture her Enigma cipher machine.

Although the film was financially successful and received generally positive reviews from critics,^[1][2] winning the Academy Award for Best Sound Editing, the fictitious plot attracted substantial criticism. British sailors from HMS Bulldog captured the first naval Enigma machine from U-110 in the North Atlantic in May 1941, seven months before the United States entered the war and three years before the US Navy captured U-505 and its Enigma machine.^[3] Anger over the film’s inaccuracies reached the House of Commons, where the Prime Minister, Tony Blair, called the film an "affront" to British sailors.^[4]

In 1942, during the Battle of the Atlantic, after sinking a merchant ship from an Allied convoy, the German U-boat U-571 has her engines badly damaged by depth charges from a British destroyer, with all of their engineers and mechanics killed in a flash fire. U-571's skipper Kapitänleutnant Günther Wassner makes a distress call that is intercepted by American intelligence. The US Navy has its submarine S-33 modified to resemble a German resupply U-boat, to try to steal the Enigma machine coding device and sink the U-571. Before the crew of S-33 receives its assignment, the submarine's executive officer Lieutenant Tyler is unhappy about a recommendation for command of his own submarine being blocked by his commanding officer, Lieutenant Commander Dahlgren. Dahlgren tells Tyler that even though he has the qualifications, Tyler cannot make immediate, even questionable, orders without hesitation, which Dahlgren believes is a crucial quality that a submarine captain needs to have.

During a storm, S-33's boarding party surprises and overwhelms the crew of U-571. After securing U-571, the American S-33 is torpedoed by the arriving German resupply submarine. Dahlgren is blown off the deck and mortally wounded; struggling in the sea he refuses rescue and orders Tyler on the captured U-boat immediately to submerge, along with the remaining crew on board: Chief Keough, Lt. Hirsch from Naval Intelligence, and seamen Mazzola, Tank, Rabbit, Trigger, and Wentz. As Dahlgren dies, Tyler takes command of U-571 and dives below the surface, where they subsequently engage and sink the resupply submarine.

Tyler orders the sub to surface for survivors, but they are only able to find and rescue two: the cook from the S-33, Eddie, and Wassner, who disguises himself as being the sub's electrician. After Tank makes repairs and gets the sub operating again, Tyler decides to route the disabled submarine toward Land's End in Cornwall. However, they are spotted by a German reconnaissance plane and a nearby German destroyer approaches. Wassner escapes captivity, knocks out Tank, and kills Mazzola, but he is subdued by Eddie and Tyler before he can sabotage the sub. The destroyer sends over some crew, but before they arrive, Tyler gives orders to Wentz and Rabbit 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. Tyler attempts to deceive the destroyer into stopping its attack, by ejecting debris and Mazzola's corpse out of a torpedo tube, faking their own destruction. However, the destroyer continues to drop depth charges. U-571 goes down to 200 metres (660 ft), and is damaged by high water pressure. They start to sink, and can only reverse this by ascending uncontrollably. Tyler orders Trigger to submerge himself in the bilge underwater 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 not reach. The crew finds that Wassner, despite being shackled, is using Morse Code to tap out a signal that the submarine has been captured, so Hirsch kills him. U-571 surfaces heavily damaged and begins to flood, unable to fire her last torpedo. The pursuing destroyer fires with her 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 destroyed. As the crew sighs in relief, Tank reports Trigger's death. However, the submarine has taken severe damage, and so the crew abandons her with the Enigma in their possession. They watch U-571 as she slips beneath the waves. They are eventually spotted in their lifeboat by a US Navy PBY Catalina flying boat.

The movie's credits then mention the successful captures of German U-boats and Enigma machines by the British and US during the Battle of the Atlantic.

U-571 was filmed in the Mediterranean, near Rome and Malta.^[5] Footage, sets and models from the movie have been reused for other productions, including Submerged, depicting the loss of USS Sailfish, and the fictional Ghostboat. A non-diving replica of the US submarine S-33^{[citation needed]} is located in Grand Harbour, Valletta.^[6]

In the U.S. the film was originally rated "R", because of a scene where Lt. Emmett is beheaded by flying debris. To get a "PG-13", the shot was redone with Emmett instead knocked overboard. This left the audience not knowing what had happened to his character. A death scene was also filmed for Major Coonan, but the effect did not work well, so it was cut.^[7]

The film was generally well received by critics. On Rotten Tomatoes, the film holds a score of 68% based on 117 reviews, with an average rating of 6.3/10. The consensus reads: "Excellent cinematography and an interesting plot accompanied by a talented cast and crew make U-571 a tense thriller."^[1] Metacritic assigned the film a weighted average score of 62 out of 100, based on 35 critics, indicating "generally favorable reviews".^[8] It performed well at the box office.^[9]

However, Roger Ebert of the Chicago Sun-Times gave the film two out of four stars, writing, "U-571 is a clever wind-up toy of a movie, almost a trailer for a video game. Compared to Das Boot or The Hunt For Red October, it's thin soup. The characters are perfunctory, the action is recycled straight out of standard submarine formulas, and there is one shot where a man is supposed to be drowning and you can just about see he's standing on the bottom of the studio water tank."^[10]

The film was nominated for two awards at the 73rd Academy Awards: Best Sound (Steve Maslow, Gregg Landaker, Rick Kline and Ivan Sharrock) and Best Sound Editing. It won the sound editing award, while losing the sound award to Gladiator.^[11][2]

The film does not portray any historical event. The British Royal Navy had captured the first naval Enigma machine in May 1941, before the US had entered the war. The American portrayal offended some of the British military and public. The Allies captured Enigma-related codebooks and machines about fifteen times during the War; all but two of these by British forces. The Royal Canadian Navy captured U-744 in March 1944 and the US Navy Coast Guard Cutter USS Campbell seized U-505 in June 1944. By this time, the Allies were already routinely decoding German naval Enigma traffic.

On the film's release, Labour MP Brian Jenkins used Prime Minister's Questions in June 2000 to state that the film was an "affront to the memories of the British sailors who lost their lives on this action." Prime Minister Tony Blair said, "I agree entirely with what you say... we hope that people realise these are people that, in many cases, sacrificed their lives in order that this country remained free."^[4] Paul Truswell, for the constituency of Pudsey, a town closely associated with HMS Aubrietia, wrote to the U.S. president Bill Clinton, who acknowledged that the film's plot was only a work of fiction.^[12] The director of the local Horsforth Museum lamented the rewriting of history, saying: "You can't rewrite history and we have to pass on the facts to the younger generation through the schools."

The first capture of a naval Enigma machine with its cipher keys from a U-boat was made on 9 May 1941 by HMS Bulldog of the Royal Navy, commanded by Captain Joe Baker-Cresswell assisted by HMS Aubrietia. The U-boat was U-110. In 1942, the Royal Navy also seized U-559, capturing additional Enigma codebooks. According to Britain's Channel 4, "the captured codebooks provided vital assistance to British cryptographers such as Alan Turing, at the code-breaking facility of Bletchley Park."^[13]

The United States's involvement in the European Theatre of the Second World War did not commence until mid-1941 with Lend-Lease, and direct, open participation did not begin until the US Navy began engaging the Kriegsmarine in the fall of 1941, months before Pearl Harbor, by which time Enigma machines had already been captured and their codes broken in Europe. An earlier military Enigma had been examined by Polish Intelligence in 1928; the Polish Cipher Bureau broke the Enigma code in 1932 and gave their findings to Britain and France in 1939, just before the German invasion of Poland.^[13]

Sub Lt. David Balme, the Royal Navy officer who led the boarding party on U-110, called U-571 "a great film"^[14] and said that it would not have been financially viable without being "americanised". The film's producers did not agree to his request for a statement that it was a work of fiction, but^[12] the end credits dedicate the film to the "Allied sailors and officers who risked their lives capturing Enigma materials" during the Second World War. The credits acknowledge the Royal Navy's role in capturing Enigma machines and code documents from U-110, U-559 and the U.S. Navy's capture of U-505.^[14]

In 2006, screenwriter David Ayer admitted that U-571 had distorted history, and said that he would not do it again.^[15] He told BBC Radio 4's The Film Programme that he "did not feel good" about suggesting that Americans, rather than the British, had captured the naval Enigma cipher: "It was a distortion...a mercenary decision...to create this parallel history in order to drive the film for an American audience. Both my grandparents were officers in the Second World War, and I would be personally offended if somebody distorted their achievements."^[15]

The Kriegsmarine destroyers rarely ventured out into the open Atlantic Ocean, but usually stayed in European coastal waters. During the destroyer's depth charge attack more than eighty depth charges are detonated in the film, despite the fact that they rarely carried more than thirty.^[16]

The German resupply U-boat would most likely not have been sunk by U-571. This would have been difficult for a German U-boat to achieve, as German sonar was not as advanced as British during the war. The only instance of a submerged submarine sinking another submerged vessel was in February 1945 when HMS Venturer sank U-864 with torpedoes.^[17]

German Type XIV supply U-boats or Milchkühe ("milk cows") did not have torpedo tubes or deck guns, being armed only with anti-aircraft guns for defense, and therefore could not have attacked other vessels.^[18]

A character mentions S-26 sinking in a test dive. The real S-26 did not sink in a test dive, instead sinking in a collision with a patrol combatant, PC-460, in January 1942.^[19]

The film portrays U-boat sailors machine-gunning Allied merchant crewmen who have survived their ship's sinking, so that they are not able to report the U-boat's position. In reality, U-boat crewmen are far more often known to have assisted survivors with food, directions and occasionally medical aid.^[20] Such assistance only stopped after Admiral Karl Dönitz issued the "Laconia order" following a U.S. air attack on U-boats transporting injured survivors under a Red Cross flag in 1942. German U-boat crews were thereafter under War Order No. 154 not to rescue survivors, which parallelled Allied policy. Afterward, U-boats still occasionally provided aid for survivors. In fact, out of several thousand of sinkings of merchant ships in World War II, there is only one verifiable case of a U-boat's crew deliberately attacking the survivors: that of U-852 after the sinking of the Greek ship Peleus in 1944.^[21]

The actual U-571, captained by Oberleutnant zur See Gustav Lüssow, was never involved in any such events, was not captured, but was in fact lost with all hands on 28 January 1944, west of Ireland.^[22] She was hit by depth charges, dropped from a Short Sunderland Mk III flying boat, EK577, callsign "D for Dog", belonging to No. 461 Squadron, Royal Australian Air Force (RAAF) ^[23] and based at RAF Pembroke Dock in Wales. The aircraft's commander, Flt Lt Richard Lucas, reported that most of the U-boat's 52 crew managed to abandon ship, but all died from hypothermia.^[24]

The real USS S-33 was stationed in the Pacific Ocean from June 1942 until the end of the war. She was sold for scrap in 1946.^[19]

The Kriegsmarine destroyer Z-49 was ordered on 12 June 1943 but never laid down, let alone completed and sailed.^[25]
