As part of the rearmament of the German re-armament, starting in 1934 the Hindenburg barracks and the Ludendorff barracks were built as tank units and Kornwestheim became a garrison town in 1935/36. The Second World War demanded numerous victims: allied air raids killed 162 people and destroyed 160 buildings. At the military front 478 resident soldiers were killed. On April 21 in 1945, the US troops took over the occupation using the existing barracks until 1993 and renamed the Hindenburg barracks into Wilkin Barracks. Since the Second World War the population has doubled due to the influx of exiles and guest workers. This resulted in an increased growth and designation of new living and commercial districts. On April 1, 1956, Kornwestheim became a large district town. Due to its location between the cities of Stuttgart and Ludwigsburg, the city was unable to incorporate neighboring communities during the 1973 regional reform. Only the restructuring undertaken by the US Army in 1954 added a new district called Pattonville to the city, although the eastern, larger part of Pattonville now belongs to the town of Remseck am Neckar.
