Why were Germanys forces turned back for the first time in the world was ll at?

Germany's forces were turned back for the first time during World War II at the Battle of Stalingrad, which took place from August 1942 to February 1943. The Soviet Union's fierce resistance, combined with harsh winter conditions and overextended German supply lines, led to significant losses for the German army. The encirclement and eventual surrender of the German 6th Army marked a turning point in the war, shifting the momentum in favor of the Allies. This defeat also boosted Soviet morale and initiated a series of successful offensives against German forces.
