Why was the battle at Stalingrad the true turning point of the war in Europe?

The Battle of Stalingrad, fought from August 1942 to February 1943, marked a significant turning point in World War II in Europe due to the decisive defeat of the German Army. It shattered Nazi Germany's aura of invincibility and halted their eastward expansion, leading to a shift in momentum towards the Soviet Union. The loss of an entire German army not only weakened their military capabilities but also boosted Allied morale and strengthened Soviet resolve, paving the way for subsequent Soviet offensives that would eventually lead to the liberation of Eastern Europe.
