The Guns of August

Barbara Tuchman opens The Guns of August at the funeral of Britain's King Edward VII in May 1910, a gathering of European royalty so grand it reads like the last moment before an entire order fell apart, then spends the rest of the book explaining exactly how that order collapsed into world war within four years. She moves through the rigid war plans each great power had drawn up years in advance, schedules of mobilization that, once set in motion by the assassination at Sarajevo, proved almost impossible to stop even as the diplomats who might have stopped them kept talking past one another. The book's real subject is miscalculation: generals certain of a quick victory, politicians who underestimated how completely a violation of Belgian neutrality would draw Britain into the fight, and an assumption on every side that economic interdependence made a long war unthinkable.

Tuchman narrates the August fighting itself, on both the Western and Eastern fronts, with the same close attention she gives the diplomatic failures that preceded it, and the book ends with an afterword on the First Battle of the Marne, the moment the short war both sides expected instead locked into the trench stalemate that would define it for four more years. She builds the account from generals' memoirs and diplomatic correspondence rather than from later scholarship, rendering statesmen and commanders as flawed people making decisions under pressure rather than as case studies in a textbook.

Reading it means following a genuinely gripping narrative that historians have since criticized for leaning too hard on memoir sources and for implying the war's course was more inevitable than it really was, criticism worth knowing going in, though it does nothing to slow the book down as a story. It suits any reader who wants to understand how nations can talk themselves into a catastrophe nobody actually wanted, told with a novelist's instinct for pacing and character even though every person in it is real.
