Patton is one of the most interesting characters in WW2.
First of all look at how the Germans feared him. They were terrified of the man. Secondly a good many of Patton’s strategic and tactical viewpoints came to pass about both the 2nd World War and the Cold War. The man also had a sense of justice. He forced German civilians that tried to ignore the existence of the concentration camps to walk through the horrors there. As a tactician and commander I doubt we had anyone better than Patton.
The man had his faults certainly. The two incidents of slapping a soldier (he discharged a firearm in at least one of those, not sure about the second), he always seemed to have trouble managing his supply lines, and he always had trouble keeping his opinions quiet. He blundered severely sending troops to liberate a POW camp that happened to have his son in law as a prisoner. Patton never believed in shell shock, “battle fatigue”.
I really enjoyed Rick Atkinson’s first two books (Army at Dawn and Day of Battle). Patton is a major player in Army At Dawn (focused on North Africa). In the second book Patton is involved briefly but you learn many of his predictions about the fight in Italy prove to be correct. I look forward to third which focuses from D-day to the end of the war. I was disappointed in the amount of time Jeff Shaara devoted to Patton in “No Less Than Victory”. True a wealth of information is already recorded about Patton but writing any WW@ novel without Patton would be like writing about the Shenandoah Valley without mentioning Stonewall Jackson.
I believe that some authors portray Patton with a bias and marginalize Patton (most notably alternative writer Harry Turtledove). Part of this is because Patton offers so much stuff to criticize in his character. Part of it also comes from the fact it is popular to criticize anyone that could be considered conservative today.
