Soviet Union, obviously. Joseph Stalin wasn't happy with Hitler, along with many others at that point.
He hoped to get the Russian army to engage in battle early but the Russians kept retreating until Borodino and then they fell back beyond Moscow. Napoleon was welcomed to Moscow by a burning city and the Russian winter.
He was attempting to swiflty take over the USSR. This battle as other failed sieges like it on Leningrad, Moscow, and St. Petersbourgh (back then Peterborough) lengthened Hitler's army into the winter. They were caught completely off-guard and had no winter equipment. Stalingrad was also a key point, because the oil fields were located just beyond Stalingrad. The oil kept the USSR war effort running strong. Taking the oil away would give the German army a boost and pull the Soviets to a halt.

Supplies were lost or spoiled. The Russian army kept retreating. The harsh climate.
no history was kept on lugers

Operation Barbarossa was a failure. It was Hitler's plan to invade and take over the Soviet Union. But the Soviet Union kept him out of Moscow and kept pushing him East until they got to Berlin and the Soviets took the city.
