Quick answers
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
How many died on 6 June?
Allied dead on D-Day are usually given in the thousands (often about 4,000+ killed, with wider casualty figures higher). German and French civilian deaths add more. Campaign totals are much larger.
Why Normandy, not Calais?
Calais was closer and more obvious -- hence Fortitude. Normandy offered space and a deception payoff.
What was Omaha?
The US beach under the highest bluffs, where the first waves took the worst punishment. It is not the whole of D-Day.
Who commanded?
Eisenhower (SHAEF), Montgomery (ground), Bradley (US First Army), Ramsay (navy), Leigh-Mallory (air) -- a coalition staff.
Did D-Day win the war?
It opened a Western Front that Germany could not resource beside the east. The war still had eleven months and a Soviet drive from the other side.
Neptune was a day; Overlord was a campaign. Teaching only the first hour of Omaha mis-teaches both.
Cobra and Falaise are the operational payoff.
