Bending the truth is an understatement. Hollywood is in the business of making money & I don't mind what they do providing it's made clear that it's entertainment & not presented as history. Unfortunately if the film is successful most people come to accept the Hollywood version as fact.
I'm using Hollywood as a general term for the film industry as a whole as they're all guilty of this practice. Some famous British war films have influenced the general public's ideas on recent history. As history is no longer taught in schools it has become accepted as the truth.
There is a glaring error in that Telegraph article which serves to illustrate my point.
U-571 (2000)
Story of how American submariners stole the Enigma code machine from a German U-boat. Fine, except in real life the submariners were British.
The only submariners were German. The film U-571 is based on 3 separate incidents involving 3 different U-Boats. One incident involved the US Navy.
May 1941. U-110 was boarded by crew from the Royal Navy destroyer HMS Bulldog. They recovered an example of the German Navy Enigma machine intact.
October 1942. U-559 was forced to the surface by the Royal Navy destroyer HMS Petard. The vital Enigma codebooks were salvaged before it eventually sank taking Lt. Tony Fasson & Able Seaman Colin Grazier with it.
June 1944. U-505 was captured by the US Navy destroyer USS Pilsbury & towed into port where a new type of Enigma machine was recovered.
True story here.
