My grandfather was left behind at Dunkirk, taken prisoner, spent the rest of the war in Poland and returned home in one piece but very thin (6ft 4 and weighing around 8 stone according to family legend). He died aged 48 a year before I was born - heart problems, which might be expected I suppose.

I'm now working with the jigsaw of records and archives in the UK to try and find a little more about what happened and where as a result of the film mainly.
