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 western front memoir Storm of Steel, he frankly depicted war’s horrors even as he extolled its glories. As a Wehrmacht captain during World War II, 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. While 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 the chaos after Stalingrad and atrocities on the eastern front.
