Codebreaking is not an easy subject to make plain, or to make exciting. There have been a number of good accounts of the work of Alan Turing and the crew at Bletchley Park, accounts that were aided by the memories of the participants and an exciting tale of successful boffins who made a difference against the Nazis. Codebreaking in previous wars has not had as spectacular a story, but in _The Man Who Broke Napoleon's Codes_ (HarperCollins) by Mark Urban, we can read about a similar victory through brainpower. Oddly, Wellington's one-man cryptography staff is only now, almost two hundred years after the fact, getting his recognition.George Scovell was of humble background, a matter that was to bedevil his entire career. He was a brilliant linguist in school and got his break in the army when he was put in charge of Wellington's communications. He had a knack for decoding, but then his first efforts were easy. But when Wellington stepped up his campaign, the French started using their "grand cipher," a fiendishly difficult code in which a single word could be encoded in multiple ways, eliminating the easy patterns that made previous codebreaking possible. Urban describes the decipherment in sufficient detail to appreciate the intellectual challenge; Scovell cracked the code when teams in London could not do so. By the eve of the decisive Battle of Salamanca in July 1812, Scovell had chipped away enough at the code to be able to tell how big an army Wellington would be facing and how long before it would be reinforced with more soldiers. It is possible that because he was working with captured documents from many sources, Scovell had such information to give Wellington that it may have been more than the on-scene French general had himself.
