In early June 1940, after reaching the English Channel following the breakthrough in the Ardennes, the Panzergruppe Guderian was formed from the XIX Army Corps, and thrust deep into France, cutting off the Maginot Line.
The rasputitsa season (literally "roadlessness", due to heavy rains and sluggish muddy roads) began to slow down the formation's progress to a few kilometres a day.
The Group's divisions had suffered heavy attrition since the beginning of the invasion and experienced shortages in fuel and ammunition due to the breakdown in logistics.
Nonetheless, Guderian expected the Red Army's resistance to collapse and, driven by National Socialist military thinking, including the idea that the "will" was key to success, continued to direct his forces to attack.
By early December, the final advance on Moscow failed in the face of stiffening Soviet resistance and due to shortages in men and equipment.
Until the Soviet counter-offensive, the Germans enjoyed complete domination of the skies and numerical advantage in material and men power during the Battle of Moscow.
Throughout 1943-44, the 2nd Panzer Army was progressively stripped of its heavy armor destined for the war on the Eastern Front, and became a primarily motorized infantry force.
The army became primarily an infantry formation at this point and found itself committed to anti-partisan operations, and personnel were accused postwar of multiple atrocities against civilians and partisans.
2nd Panzer Army took part in the Battle of the Transdanubian Hills in March 1945 before surrendering at the end of the war to both Soviet and Anglo-American forces.
