You mention 2 or three accomplishments all of which you discount. Apparently, according to you, Patton’s strength was being in the right place at the right time and schussing weak opponents .
Also, you put the lie to the Germans respect of Patton. Apparently, they were poor judges of military commanders.
The fact is that Patton was a compulsive self promoter, at a time when the American press was looking for a heroic commander. It was a match made in heaven, with little substance behind it. I just don't buy the hype.
