Ernst Jünger was one of twentieth-century Germany's most important--and most controversial--writers. Decorated for bravery in World War I and the author of the acclaimed memoir from the western front, Storm of Steel, he frankly depicted the war's horrors even as he extolled its glories. As a Wehrmacht captain during the Second World War, Jünger faithfully kept a journal in occupied Paris and continued to write on the eastern front and in Germany until its defeat--writings that are of major historical and literary significance. Jünger's Paris journals document his Francophile excitement, romantic affairs, and fascination with botany and entomology, alongside mystical and religious ruminations and trenchant observations on the occupation and the politics of collaboration. Working as a mail censor, he led the privileged life of an officer, encountering artists such as Céline, Cocteau, Braque, and Picasso. His notes from the Caucasus depict chaos and misery after the defeat at Stalingrad, as well as candid comments about the atrocities on the eastern front. Returning to Paris, Jünger observed resistance and was peripherally involved in the 1944 conspiracy to assassinate Hitler. Ernst Jünger, one of twentieth-century Germany’s most important and controversial writers, faithfully kept a journal during the Second World War in occupied Paris, on the eastern front, and in Germany until its defeat—writings that are of major historical and literary significance.
