Pre-WWII US exercises, influenced by Patton and his peers, successfully showcased armored warfare. Patton was eccentric, boring audiences with detailed lectures on Roman generals and claiming to be the reincarnation of Napoleon, which disconnected him from his troops. Montgomery, leading the Third Division, trained his men endlessly and formed a cohesive team before the Dunkirk evacuation, seeing the retreat as a challenge to rebuild. Rommel was given command of the 7th Panzer Division in 1940 and, due to his aggressive success, became known as the commander of the "phantom division," celebrated by Nazi propaganda.
