Edward R. Murrow is the narrator and interviewer in this wartime look at Dover, the closest approach to German-held Europe during the Second World War. He gives a brief description of the events around Dunkirk, and then it's on to the inhabitants, who recite their canned speeches of English-muddle-through attitudes with little polish but obvious sincerity.
It was made by the British Ministry of Information for the American audience. We had just entered the war, and so documentaries like the fierce LONDON CAN TAKE IT! we're replaced by ones like this. Murrow was an obvious choice for the narration, and he took it. Americans were used to his voice, talking turkey to them about the problems in Europe, and had been for four years, since his earlier reports on the Munich Conference. There was never any doubt that he was an American, and his loyalty was to this country, even if he had an opinion about the war, based on his own experiences. That was his reputation, that was what people expected, and it was probably the man who he was. He always had an opinion and was never afraid to voice it. People wrote him letters telling him he was wrong, and he sent the, all the same postcard with the same reply: "Dear Sir Or Madam: you may be right."
