Military unit
Army Group A (German: Heeresgruppe A) was the name of three distinct army groups of the Heer, the ground forces of the Wehrmacht, during World War II.
The first Army Group A, previously known as "Army Group South", was active from October 1939 to June 1941 and notably served in the Battle of France as the decisive army group in the implementation of the "Sickle Cut" military plan that inflicted crushing subsequent defeats on the French armed forces at occasions such as the Battle of Sedan, Battle of Boulogne and Battle of Dunkirk and that ultimately led to the Armistice of 22 June 1940. Army Group A was subsequently used in the German occupation of France and temporarily became the first Oberbefehlshaber West in German-occupied France. It was eventually replaced in this function by Army Group D and redeployed to German-occupied Poland in preparation for Operation Barbarossa. At the commencement of that attack, Army Group A was renamed "Army Group South" on 22 June 1941, ending the first deployment.
The second Army Group A was inserted into the German line on 7 July 1942, when Army Group South was split during the German 1942 summer offensive ("Case Blue") into Army Group B in the north (directed towards Stalingrad) and Army Group A in the south (directed towards the Caucasus). It advanced towards the Terek river, but was eventually forced to withdraw by the winter of 1942/43, concurrent with the decisive defeat of Army Group B in the Battle of Stalingrad. Initially confined to the Kuban bridgehead and the Crimean peninsula, Army Group A fought a rearguard action against the Red Army during its westwards withdrawal through Ukraine. On 2 April 1944, it was renamed "Army Group South Ukraine".
The third and final Army Group A came into existence on 23 September 1944, when the previous Army Group North Ukraine was renamed "Army Group A". It existed for about five months that were marked by constant withdrawals from the advancing Red Army and eventually left Army Group A at the Oder river line. On 25 January 1945, Army Group A was one of several army groups to be renamed, receiving the designation "Army Group Center". No subsequent Army Group A was formed.
