Spoken by George C. Scott in the film Patton, portraying his defeat of what he thought were forces under the command of Erwin Rommel; however, the book portrayed in that film is purely fictional — Rommel never finished the book he was writing on tank warfare, but did write a book on his experiences in WW I. It was widely read, regarded a classic of modern military tactics, and published in abbreviated form for study by US army officers.
