 FACT: Patton is shown having read a book, "The Tank in Battle", by  his adversary, Erwin Rommel. The book "Panzer greift an" was however  never finished by Rommel. Most of what was to be in "The Tank in  Attack" (which is the correct translation of the German title) can  be found in the book The Rommel Papers, which is made from notes and  diary entries by Field Marshal Rommel during the Africa campaign.
