The battle of Stalingrad was fought between the invading forces of Nazi Germany and the forces of Soviet Union (Russia) who were defending the city. The battle was fought from August 1942 to February of 1943. This was the decisive battle of World War II because it ended the German offensive as well as destroying much of the German armies.
