Final answer:
Germany did not drive the Russians into full retreat in either World War I or World War II.
Step-by-step explanation:
No, Germany did not drive the Russians into full retreat. While the German armies made significant advances into Russian territory during World War I, the Russian forces were able to mount a furious defense and check the German advance in the winter of 1916-1917. However, due to the dire situation on the home front and increasing desertions by soldiers, Russia eventually faced defeat, leading to the Russian Revolution and their withdrawal from the war. In World War II, Germany initially made progress on the eastern front but ultimately faced resistance and defeats, most notably in the battles of Stalingrad and Kursk.
