LEIPZIG, Germany – About three miles southeast of the center of Leipzig stands the Volkerschlachtdenkmal, a 300-foot high monument commemorating the defeat of Napoleon by a coalition of European powers in 1813. It is a deeply eerie place, in part because of the knowledge that 127,000 soldiers died there and in part because of its awesome scale, which itself hints at two other details: it was constructed in a spirit of nationalistic German militarism on the eve of the First World War, and it was so beloved by Hitler that he held a number of key meetings within its granite walls.
