The Battle of Stalingrad was a turning point in the war because it marked the end of Germany's advancement.

Explanation:

The Battle of Stalingrad took place between the summer of 1942 and February 2, 1943. It opposed the soldiers of the Red Army to the German, Italian, Romanian and Hungarian forces for the control of the strategic region between the Don and the Volga and the important political and economic center of Stalingrad.

The battle, which began with the advance of the Axis troops to the Don and the Volga, came to an end after a series of dramatic and bloody phases, with the annihilation of the 6th German Army surrounded in Stalingrad and with the destruction of great part of the other Germanic and Axis forces engaged in the southern strategic area of the eastern front.  

This battle marked the first great political-military defeat of Nazi Germany and its allies and satellites on the eastern front as well as the beginning of the Soviet advance westward, which would end two years later with the conquest of the Reichstag building during the Battle of Berlin.
