Haven't seen the film yet and probably won't till its on TV, but have read many books and have been to Dunkirk many times on ship refits, always winter time so no museums open etc, I normally go for my run along the beach front and take different routes to the beech, last time I was there I took a different route that led to one of the evacuation points on the east side, (pics have gone since photo bucket highjacked my account) but am sure I posted them ?? one of the later Germanfortifications was there a bigger version of our "PILL box" one thing that does catch the eye on the west side of the beech front is a big fortification that looks like they couldn't destroy it so used part of it as a house (I'll try and get some pics next time)
Something that really hit home for me was a visit to the Town Cemetery the previous year, one Grave in particular stood out with a photograph on, lifting it up on the back was written "His Mum and Dad" ........ can only guess they visited there sons grave not long after the War as it still retains a wooden cross. Certainly brings a lump to the throat and a tear to the eye
Again I don't have the pics anymore but they are in the link below.
