Definitely not a chance for victory for Germany. Not even a draw. But losing the AG center´s men is a shame for Hitler´s war planning. And this was the famous "not a step back" command and making fortress cities etc. So it definitely would have looked alot different with retreating in some kinda order and not losing all those men. I bet Hitler could have kept the war in East ( and West ) going on for another 6 moths or more at least with similar tactics as in Italy, letting the troops move backwards to new prepared defensive lines.
