The bombing of Stuttgart in World War II was a series of 53 air raids that formed part of the strategic air offensive of the Allies against Germany. The first bombing (by 20 aircraft of the Royal Air Force) occurred on August 25, 1940, and resulted in the destruction of 17 buildings. The city was repeatedly attacked over the next four and one-half years by both the RAF and the 8th Air Force as it had significant industrial capacity (including the Daimler and Porsche automotive factories) and several military bases, and was also a center of rail transportation in southwestern Germany. Stuttgart endured 18 large-scale attacks by the Royal Air Force (RAF) during the war (the first and last of which were on 5 March 1942 and 13 February 1945 respectively), during which of bombs were dropped on the city, but the RAF concluded that its attacks against Stuttgart were not as effective as they could have been: Stuttgart's experience was not as severe as other German cities. Its location, spread out in a series of deep valleys, had consistently frustrated the Pathfinders and the shelters dug into the sides of the surrounding hills had saved many lives. History of Stuttgart Even before World War II, in 1916, Stuttgart had been a potential target for air raids because of its short distance from the Western Front of the First World War. In the next two years, the city would be attacked by Allied aviators on several occasions throughout 1917 and 1918, the Daimler plant in Stuttgart being of special interest to them. When the Royal Air Force's Bomber Command began its strategic bombing command during the Second World War, it initially targeted airstrips in Norway and France and U-boat pens in northern France, but soon added civilian targets, such as Stuttgart, to its target list in March 1940. As early as May of that year, the RAF attempts to bomb targets in Württemberg, of which there were two among the mostly rural region: Stuttgart and Friedrichshafen.
