Cassy Fiano has a fine D-Day anniversary post at hotair.com, with clips of the invasion, FDR's speech, and Reagan's 40 years later.
It's also worth taking a look at General Eisenhower's Order of the Day, beginning "You are about to embark upon the Great Crusade," and ending, "And let us all beseech the blessing of Almighty God upon this great and noble undertaking." And do re-read Ike's terse "failure message" (which, thank God, never had to be sent), drafted the day before D-Day in case Operation Overlord failed. The handwritten message is here.
Its last sentence is deservedly well-known and much-admired--"If any blame or fault attaches to the attempt it is mine alone." One thing I hadn't realized until looking again at the reproduction: Ike crossed out in the original, "the troops have been withdrawn," and wrote instead, "I have withdrawn the troops."
An impressive man, and an impressive leader of men.
