Misconception 1 One of the more common misconceptions about the fateful mission to Dresden, is that the RAF and USAAF bombed the city in some sort of spiteful vengeful fury, using a flimsy excuse of transport targets as cover. However, if one takes a closer look at this, the facts seem to be somewhat different from such post-war interpretations. At the time of the mission, Dresden was the sixth largest producer of arms and materiel for the war effort in Germany, with 127 products marked as originating in the city according to the Oberkommando der Heeres origin code system (Liste der Fertigungskennzeichen für Waffen, Munition und Gerät, Heereswaffenamt Berlin 1944). Many industries that had previously produced civilan goods had been integrated into the war economy and shifted production to such supplies and equipment. Some examples of the companies located in the city are Zeiss-Ikon (employing some 16,000 people), Seidel & Nauman, Siemens, Sachsenwerke and the Radio-Mende, as well as numerous smaller high-tech indutries. Military production taking place in the city were, among others, Zeiss-Ikon optical equipment (sights and field glasses), the Siemens glass factory, as well as industries producing Junkers aircraft engines, cockpits for Messerchmitt fighters, radar components, electronic components, delayed-reaction anti-aircraft artillery fuses, guidance systems, turbines, communications equipment and gas masks. Misconception 2 The industries were located outside the city. In fact, many industries, especially the small high-tech firms, were located in the city, with the important Friedrichstadt industrial area located next to the RAF target aiming point for the first raid.
