Army Group A (Heeresgruppe A) was the name of several German army groups during World War II. During the Battle of France, Army Group A was composed of 45½ divisions, including 7 panzer divisions. It was responsible for breaking through the heavily-forested Ardennes region. The operation, which was part of Fall Gelb (Case Yellow), was resoundingly successful for the Germans, as the army group outflanked the best troops of France and its allies, eventually leading to France's surrender. In 1942, Army Group South on the Eastern Front against the Soviet Union was split into Army Group A and Army Group B, and Army Group A was responsible for the invasion into the Caucasus. In 1945, months before the fall of Nazi Germany, Army Group A was renamed Army Group Centre.
