Trivia: In reality, Adolf Hitler ordered his commanders and troops to stand down and allow Allied forces to escape at Dunkirk. The German General von Blumentritt is quoted as saying "He (Hitler) then astonished us by speaking with admiration of the British Empire, of the necessity for its existence, and of the civilisation that Britain had brought into the world...He said that all he wanted from Britain was that she should acknowledge Germany's position on the Continent." But the exact reason for the order remains unknown.Charles Austin Miller

Question: A few minutes into the movie you see English troops all lined-up on the beach with no obvious means of evacuation. That leaves them very exposed to German gunfire and aerial attack. It would seem that the English soldiers would stay off the beach until actually called-up for evacuation. Not to mention the obvious requirement that some troops would have to stay off the beach to defend the evacuation area. How realistic are those scenes?
