This is the first time I've heard that any major generals favored the move south. It appears many historians (at least the ones I've read) have neglected to dwell on this fact.
Most historians writing after the War were relying on the testimony, affidavits, studies done for the U.S. Army, by the German generals, including Halder. Their common themes were: all the mistakes were Hitler’s [if only he’d listened to us], and all the criminal acts were committed by the SS, including the same Waffen SS that saved their bacon more than once.
I first read of the dissension over the Kiev encirclement in, I believe, Alan Clarke’s “BARBAROSSA”.
