The escape from Stalag Luft III is one of the greatest stories of the Second World War, an enduring example of raw courage and ingenuity. The story of the making of The Great Escape, by contrast, is an enduring example of the way that Hollywood can twist history to meet the requirements of American patriotism and the demands of pampered actors.

The problem with the true story of the escape, from Hollywood’s point of view, was that it involved no Americans. True, the camp had contained American prisoners, but all of these were moved out before the escape took place. The director, John Sturges (who also made The Magnificent Seven), was told by his Hollywood bosses to write American heroes into the script or abandon the project. The resulting film not only included fictional American characters, but was also dominated by them: Steve McQueen, James Garner, James Coburn and Charles Bronson.

McQueen, who played The Cooler King, insisted that his role be even bigger, with a scene in which he could show off his motorcycling skills. The fictional motorbike escape scene was created, with a growling Triumph 650 — which was not built until 1963. Bud Elkins, McQueen’s stunt double, performed the more dangerous jumps.

This, then, was the Hollywood take on history: an event that never took place, involving an American who was not there, played by a double, on a motorbike that had not yet been invented. No wonder the veterans booed the Steve McQueen character at the 65th anniversary gathering in Zagán.

American film-makers have been invading and occupying feats of British heroism ever since the war, although Churchill himself did his best to repel the invasion. Britain’s wartime Prime Minister strongly objected to Objective Burma! (1945), starring Errol Flynn, because it installed American heroes in a conflict waged by British, Indian and Commonwealth troops.

The film even prompted an editorial in The Times: “It is essential both for the enemy and the allies to understand how it came about that the war was won . . . nations should know and appreciate the efforts other countries than their own made to the common cause.” The film was withdrawn from release here and only reached cinemas in 1952, accompanied by an apology.

Steven Spielberg’s Saving Private Ryan has been criticised for depicting Tom Hanks and his American soldiers battling the crack 2nd SS “Das Reich” Panzer tank division, when that conflict was actually fought by British and Canadian troops 100 miles to the east.

Undoubtedly the most egregious example of America’s cultural colonisation of the best war stories is U-571 (2000), which depicts American submariners stealing the Enigma code machine from a German U-boat. The capture and breaking of the Enigma code was carried out by the British, before America had even entered the war.

While Hollywood misrepresents history, it also confers immortality. The Great Escape may not be great history but it is a great film. It may Americanise and edit the facts but without it one of the most remarkable episodes in wartime history might languish virtually unknown.
