During the Second World War, Germans fought a “two-front war.” A “community of fate” bound together Germans at home and Germans in uniform who carried the war beyond Germany's borders. “Between 1939 and 1945, there was no doubt that civilians were no longer excluded from the fighting; they found themselves right in the middle of it—as actors, as observers, and as those who bore the suffering” (part 1, p. 2) of the war. The Nazi leadership knew this from the start, and only days after the Nazi invasion of Poland, Hermann Göring was exhorting a factory workforce to remember: “We are now all fighters at the front!”(part 1, p. 8). Jörg Echternkamp reminds us of this in his introduction to this massive two-part volume, the latest installment in the history of Germany in the Second World War that has occupied historians of the Military History Research Office (Militärgeschichtliches Forschungsamt, or MGFA) for the last twenty-five years. Echternkamp is the editor, and he deserves enormous credit for pulling together a collection of twenty essays—some of which could easily stand on their own as monographs, all of which are grounded in staggering amounts of original research—that not only summarize what we know about the impact of the war on the homefront in Germany, but also add considerably to that knowledge. Previous volumes in the MGFA series (seven of which are available from Oxford University Press in English translation) have focused primarily on the military planning, the war at the front, and the organization of the war economy at home. In the more than 2,000 pages of this two-part volume, contributors turn their attention to the impact of the war on German society. The results are extremely impressive, and what Echternkamp has brought together will be the starting point for anyone who wants to understand the war at home in Germany.
