If you get the chance, the D-Day Museum in New Orleans is a stirring visit. It has thousands of artifacts from the invasion, including a copy of this letter (if not the original) and Eisenhower’s speeches for after the operation. He actually prepared two: one for a successful landing, one for if it was repulsed. In the former, he gave credit to the GIs who bore the burden. In the latter he took full responsibility for the failure.
Very moving.
Unlike the present POS who now occupies the WH and knows not the simplest meaning of the word "honor".
