When the Western Allies launched the amphibious invasion of Normandy on 6 June 1944, Panzer Lehr, as a part of the strategic armored reserve (Panzer Group West), was held back from the fighting during the crucial first days. It was soon released, reached the front, and was committed to battle against the British and Canadians on June 8. It was placed in the front line adjacent to the 12th SS "Hitlerjugend" Division, where it defended Caen and fought several British offensives to a standstill.
