The History Underground
A pretty good You Tube channel (for an American), which looks especially at the D-Day landings, amongst other WW2 battle sites visiting and telling the stories of the events.
Obviously he concentrates on the American input, but does visit the British landing sites as well.
On the downside, he mispronounces a lot of the French villages (sorry cities), and whilst visiting the American cemeteries with due reverence, is very rude about the German cemetery he visits.
