In May 1871, four months after German artillery forced the surrender of Paris, Blackwood’s Magazine published an anonymous novella called “The Battle of Dorking”. A German army lands on the English coast; the volunteers break on a ridge in Surrey; England falls within days. The author turned out to be a serving army engineer officer, George Chesney, and his pamphlet became a sensation — more than 80,000 copies, imitations across Europe, and a new literary genre: the future-war story.
It took months, not decades, for the genre to be identified for what it was. Gladstone, the Prime Minister, publicly attacked the novella — not as bad fiction, but as alarmism designed to stampede the country into military spending. He read it correctly. Chesney’s invasion was imaginary; his appeal for army reform and bigger budgets was entirely real. The fiction was the delivery mechanism.
Lawrence Freedman, the King’s College London historian who traced the whole 150-year literature in The Future of War: A History, found that the founding case set the pattern. The stories keep the same furniture — the surprise blow, the war decided in days, the nation caught unprepared — and the same function underneath: forecasts of war are rarely neutral acts of analysis. They are, in his reading, about the present as much as the future. Someone is warning, someone is budgeting, someone is selling — a service’s share, a weapon, a reform, a book.
That does not make the forecasts worthless; Chesney’s Britain did, after all, have real defects worth fixing. It makes them evidence of a particular kind. A confident picture of the next war tells you something reliable about who painted it and what they want — and something far less reliable about the war. So the first question to put to the next one is not whether it is right. It is what it is asking you to buy.
