A detailed breakdown of cracking 12 Napoleonic-era telegrams: a 1,450-word codebook numbered alphabetically was the key, out-of-codebook words were spelled syllabically (General de Cotte = 248 co + 1240 t + 1249 te), and readings were graded green/yellow/grey by confidence. Includes the June 9 Milan entry telegram.
