Many Nazi soldiers who were of lower ranks stated that they were simply "following orders" which became known as the Nuremberg Defense. The Allies anticipated such a defense and stated that: "The fact that a person acted pursuant to order of his Government or of a superior does not relieve him from responsibility under international law, provided a moral choice was in fact possible to him.". Despite this declaration, very few low-rank soldiers were tried. This may be due in part to a difficulty to find evidence against these men, when their victims would not have known their names. For the higher-ups, however, things were much different. High ranking officers would likely have been easier to correlate with reports of war crimes, and some who were captured were tried at the Nuremberg Trials, along with other highest ranking people captured from the Nazi administration. They were sentenced to prison terms, and in a few cases, death.
Most soldiers were treated fairly. Americans became friends with many German soldiers and have said that they felt at home the most in Germany. The SS and the men who worked and controlled the concentration and death camps, on the other hand, was sentenced to life in prison. EDIT: The Germans and Russians hated each other through the entire war.
