Battle of Stalingrad
In the east, they had captured land including Leningrad in the north and  Rostov-on-Don in the south. There were a number of places where Soviet attacks had pushed the Germans back (to the northwest of Moscow and south of Kharkov) but this did not threaten the Germans. Hitler was confident that he could beat the Red Army after the winter of 1941. Even though Army Group Centre had heavy losses near Moscow the previous winter, 65% of its infantry had not fought and had been rested and given new equipment. Army Groups North and South had also not had a hard time over the winter.  Stalin was expecting German summer attacks to again be directed against Moscow.
