Quick question why did you choose Rommel? Rommel, is a good commander it's just that why not other German commanders? Leeb, Bock, Kluge, or maybe generaloberst Gotthard Henrici? The latter may not work as he was more defensive-minded. You get the point.
Leeb, Bock, and Kluge could have been good choices and both were skilled commanders in their own right. What happened to them in your story just curious.
