(later Panzerjäger-Abteilung 27)). Wehrmacht Panzerjäger-Abteilung 27 was later moved to Füssen. The MAN factory at Augsburg was the largest German manufacturer of engines for U-boats in World War II and became the target of the Augsburg Raid. When the Avro Lancaster bomber was new in service, the RAF sent 12 at low level to bomb the factory in daylight, on 17 April 1942. The bombers were intercepted en-route and only five returned, all damaged. The factory was damaged but production continued; the factory was repeatedly bombed later. A subcamp of the Dachau concentration camp outside Augsburg supplied approximately 1,300 forced labourers to local military-related industry, especially the Messerschmitt AG military aircraft firm, headquartered in Augsburg. In 1941, Rudolf Hess, without Adolf Hitler's permission, secretly took off from a local Augsburg airport and flew to Scotland, crashing in Eaglesham. His objective was to meet the Duke of Hamilton in an attempt to mediate the end of the European front of World War II and join sides for the upcoming Russian Campaign. The Reichswehr Infanterie Regiment 19 was stationed in Augsburg and became the base unit for the Wehrmacht Infanterie Regiment 40, a subsection of the Wehrmacht Infanterie Division 27 (which later became the Wehrmacht Panzerdivision 17). Elements of Wehrmacht II Battalion of Gebirgs-Jäger-Regiment 99 (especially Wehrmacht Panzerjäger Kompanie 14) was composed of parts of the Wehrmacht Infanterie Division 27. The Infanterie Regiment 40 remained in Augsburg until the end of the war, finally surrendering to the United States when on 28 April 1945, the U.S. Army occupied the city. The city and its Messerschmitt works were bombed on three occasions during the war. Collateral damage included the destruction of just under 25% of all homes in the city and the deaths of several hundred people. Following the war, the three Kaserne would change hands confusingly between the American and Germans, finally ending up in US hands for the duration of the Cold War. They became the three main US barracks in Augsburg: Reese, Sheridan and FLAK. US Base FLAK had been an anti-aircraft barracks since 1936 and US Base Sheridan "united" the former infantry barracks with a smaller Kaserne for former Luftwaffe communications units. The American military presence in the city started with the U.S. 5th Infantry Division stationed at FLAK Kaserne from 1945 to 1955, then by 11th Airborne Division, followed by the 24th Infantry Division, U.S. Army VII Corps
