which was added to the municipality of Dewangen. Forst, Rauental and Vogelsang were added to Essingen (in 1952 the entire former municipality of Unterrombach was merged into Aalen, with the exception of Forst, which is part of Essingen until present). In September 1944, the Wiesendorf concentration camp, a subcamp of Natzweiler-Struthof, was constructed nearby. It was designated for between 200 and 300 prisoners who were utilized for forced labor in industrial businesses nearby. Until the camp's dissolution in February 1945, 60 prisoners died. Between 1946 and 1957, the camp buildings were torn down; however, its foundations are still in place in house Moltkestraße 44/46. Also, there were several other labour camps which existed where prisoners of war along with women and men from occupied countries occupied by Germany were pooled. The prisoners at these other camps had to work for the arms industry in major businesses like Schwäbische Hüttenwerke and the Alfing Keßler machine factory. In the civic hospital, the deaconesses on duty were gradually replaced by National Socialist People's Welfare nurses. Nazi eugenics led to compulsory sterilization of some 200 persons there. Fortunately, Aalen avoided most of the combat activity during World War II. It was only during the last weeks of the war that Aalen became a target of air warfare, which led to the destruction and severe damage of parts of the town, the train station, and other railway installations. A series of air attacks lasting for more than three weeks reached its peak on 17 April 1945, when United States Army Air Forces planes bombed the branch arsenal office and the train station. During this raid, 59 people were killed, more than half of them buried by debris, and more than 500 lost their homes. Also, 33 residential buildings, 12 other buildings and 2 bridges were destroyed, and 163 buildings, including 2 churches, were damaged. Five days later, the Nazi rulers of Aalen were unseated by the US forces. Post-war era Aalen became part of the State of Baden-Württemberg, upon its creation in 1952. Then, with the Baden-Württemberg territorial reform of 1973, the District of Aalen was merged into the Ostalbkreis district. Subsequently, Aalen became seat of that district, and in 1975, the town's borough attained its present size (see below). The population of Aalen exceeded the limit of 20,000, which was the requirement for to gain the status of Große Kreisstadt ("major district town") in
