My question is about German Army Surrender in Reims. The unconditional surrender was signed by Colonel General Alfred Jodl, on behalf of the Oberkommando der Wehrmacht and General Walter Bedell Smith on behalf of the Supreme Commander of the Allied Expeditionary Force. Supreme Commander Eisenhower was in the same building, on the second floor (Jodl and Smith signed the act in the map room on first floor). After the signing Eisenhower received the German delegation in his office.
So, my question is, why Eisenhower didn't sign the act?
I've tried to find some explanation and found two answers:
Now, I don't know if one, both or none of these answers is true. I don't know how to compare ranks, but Generaloberst ("Colonel General") is supposed to be above four-star full general and below five-star field marshall. Eisenhower was the General of the Army which is a five-star rank. So Jodl was four-and-a-half-star and Eisenhower was five star. Did this difference really matter?
