It’s interesting how the documentary makers use clips from the 1955 film, without stating their source – what we would now call a dramatised reconstruction. These are mixed in with real wartime stills and film clips. Be that as it may, it is still a mainly accurate telling of the story, and well repays a repeat viewing.
