  • General Hans Cramer, last commander of the German Afrika Korps, was repatriated due to ill health; before he departed Britain, he was shown evidence of the massive Allied build-up, but was misinformed as to the location of these forces; when he was later debriefed in Berlin, Germany, this misinformation helped deceive the Germans as to the actual target of the invasion. On the same day Cramer was repatriated, a single USAAF B-24 bomber ("Lorelei" 41-29300), escorted by eight P-51 fighters, loaded with the new top-secret Azon bombs successfully destroyed four bridges leading into Normandie, France; Lieutenant Colonel F. M. O'Neil (commanding officer of 753rd Squadron) and Captain Fred DeNeffe were the mission pilots; the entire crew was awarded the Distinguished Flying Cross. ww2dbase [Main Article | TH, AC]
