Question

What does a Western Front have to do with the "German sandwich" strategy?

Answer 1

Answer:

Believe this is WWII strategy of the allies.  Early in the war Russia was bearing the brunt of German military might.  He begged, chastized England and USA for not opening a western front (land invasion in France to "sandwich" the Whermact /German army to defend two fronts.

Explanation:

England, America and other allies were tieing up German and Italian Axis forces in North Africa, then Sicily, on to Italy.  That was not enough, seaboard invasion on D-Day June 6,1944 finally brought the second front that sandwiched Germany between Russia/USSR on the East and Anglo-American on the Western front

May God Bless all who gave so much to defeat Nazi tyranny.  Civilians in Europe, Russia, Poland etc. suffered mightily.
