This summer marks the 80th anniversary of the fall of France. The fall was as sudden as it was shocking: six weeks after German panzers, sweeping north of the Maginot Line, punched through the thick forest of the Ardennes in mid-May, the newly appointed leader of the French government, Marshal Philippe Pétain, addressed the nation: “It is with a heavy heart that I announce that hostilities must end.” Among those who heard the radio address was a French army captain who, though a decorated veteran of World War I, had again insisted on seeing combat. In a matter of weeks, he dashed off “a statement of evidence” of the events in which he had just participated.
Penned in what the author, Marc Bloch, confessed was “a white heat of rage,” the resulting book, L’Étrange défaite, or Strange Defeat, remains among the most incisive analyses of France’s collapse. An iconoclastic historian of medieval France, Bloch developed an influential, though elusive, notion of what he called mentalités: the intellectual and emotional structures that, no less certainly than material factors, shaped how past generations conceived their world. Not surprisingly, Bloch believed that any worthwhile explanation of how France came to suffer “a defeat no one would have thought possible” required a foray into the mentalities of its political and military elites.
