Factual error: U-571 was sunk on January 8, 1944, by an Australian Sunderland. She was previously damaged by an Allied destroyer on March 22, 1943, but managed to come back to the base. All supply submarines (Type XIV or Type VIIF) were actually sunk by Allied planes or surface ships. I know that the movie is entertaining rather than historical, but why didn't the movie makers choose boats that disappeared without a trace instead?
Trivia: U-571 cause quite a stir in England especially in the small northern town of Horsforth (where I actually live), because we felt the movie 'Hollywood-ised' a British victory. The people of Horsforth raised an astonishing £241,000 in one week (about £4million today) to fund the building of the HMS Aubretia, the ship that captured the first enigma machine when it depth charged U-110. It caused so much upset amongst people that President Bill Clinton wrote a letter to the people of Horsforth praising the town for their part in the war effort. The letter is now on display in the local museum.
Question: At first we learn that Tyler is not getting his own submarine, but then a few scenes later and he's being fired from the navy. What happened?
