On the recommended reading for 14 years old there were books, including 'The Battle of Tannenberg'. The book includes a passage where it states "A Russian soldier tried to bar the infiltrator's way, but Otto's bayonet slid gratingly between the Russian's ribs, so that he collapsed groaning. There he lay before him, smoke and distinguished, his dream's desire, the Iron Cross." This was used to promote Germany and boast about how they should be proud of the country they live in.
