It's been six decades since the Second World War came to an end, but those grim years are still seared into the memories of those who fought and suffered in the conflict.

One man who certainly hasn't forgotten that time, despite his 84 years, is Bert Evans.

He can especially recall the day when, retreating from the German Panzers, his unit was captured and herded into a barn.

Bert was one of only five men who came out alive after the Germans threw in grenades, slaughtering 80 of his comrades.

Bert also doesn't need reminding of the name of the German general giving the orders on that horrific day.

He spent more than 50 years trying to have Wilhelm Mohnke indicted for war crimes, until Mohnke's death in 2001.

So when Mohnke's name came up again in a new German film about the end of the Third Reich, he didn't have to rack his brains to place him.

But the portrayal of Mohnke in the film, Downfall, didn't quite chime with Bert's own recollections.

Mohnke was depicted as a humanitarian who pleaded for lives to be saved. Wrong. He was a monster, says Bert.

Downfall has been praised as a brave attempt to accurately capture the last doomed days of arguably the most evil man who ever lived - despite accusations that it 'humanises' Hitler.

However, it looks like the film-makers didn't do their homework quite well enough.

For most of us, Downfall is of historical interest only.

But for Bert, it's personal.
