"In October 1938, after reading Infantry Attacks, Hitler selected Rommel to be his escort during his march into the Sudetenland. In this position, Rommel had charge of over 300 men and received a promotion to colonel after completing his service to the Fuhrer. As colonel, he would take up a new teaching position at the war school south of Vienna.[59] When he was called back to guard duty for Hitler after the full German invasion of Czechoslovakia in March of 1939, Rommel seemed to believe his fortunes were improving and described for his wife how he "persuaded [Hitler] to drive on [in face of a missing SS escort] under my personal protection. He put himself in my hands." An impressed Rommel then ventured a question: "Isn't it wonderful that we have this man?"
