U571 which was a mockery of an actual event in WW2 in which two Royal Navy men died.There were many events in that war of which the US Navy can be justly proud , why they had to make such a film is beyond me.
The film's plot, though a complete work of fiction, is minutely based on real events. Though the film was generally well received,[1] the plot attracted criticism for two reasons: first, it was British personnel from HMS Bulldog who first captured a naval Enigma machine, from U-110 in the North Atlantic May 1941, before the United States entered the war. Second, German U-boat crews were portrayed in a negative light.
The real U-571 was never involved in any such events, was not captured, and was in fact sunk in January 1944, off Ireland, by a Short Sunderland flying boat from No. 461 Squadron, Royal Australian Air Force.
