Heeresgruppe C
The 7th Army was activated in Stuttgart on August 25, 1939 with General Friedrich Dollmann in command. At the outbreak of the war, the 7th Army defended the French border and manned the Westwall in the Upper Rhine region. At the start of the Campaign in the West in 1940, the 7th Army was part of General Wilhelm Ritter von Leeb's Army Group C. On 14 June 1940, Army Group C attacked the Maginot Line after it had been cut off by armored units of the XXXXI Panzer Corps. Lead elements of the 7th Army reached the area in front of Colmar and later pursued parts of the French 2nd Army Group into Lorraine. At the conclusion of the campaign, the 7th Army was in eastern France. From July 1940 until April 1941, the 7th Army guarded a region of the coast in southwestern France. From 18 April 1941, the 7th Army was responsible for coastal defense in Brittany and Normandy. By mid-1944, the 7th Army was part of Erwin Rommel's Army Group B.
