Operation Braunschweig (Eng: Brunswick), named after the German city, was the German summer offensive that began on 28 June 1942. The operation was initially named Fall Blau (Case Blue), which is the common name used for the whole offensive. The name was changed from Blau to Braunschweig on 30 June. The plans following the original Case Blue (originally named Blue I and Blue II) were renamed to Operation Clausewitz (1942) and Operation Dampfhammer. Clausewitz detailed the beginning of the operations of Army Group A in July 1942, Dampfhammer the follow-up operations in July 1942.
