I'm not sure what PJ meant with this statement, but anyone who has studied Patton's campaign's in NA, Sicily, and France surely could not characterize his tactics as 'indelicate' grind. The end-around to Palermo....the Lorraine Campaign......the relief of Bastogne........” The Crossing of the Rhine that is fact was a complete strategic mistake.
If Market Garden had succeeded it would have opened the road to Berlin to the Western Allies.
Patton move just distract material and men to a useless front where the Allies were stacked.
