Case Blue
Operation Braunschweig ("Brunswick"), named after Braunschweig, 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 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.
