In 1908 it was discovered, the Admiralty had, in fact, changed the signal code in November 1803, after the 1799 version had been captured by the French, and new code books had been issued to Nelson's fleet at Cadiz in September 1805.
V roku 1908 však bolo zistené, že britská Admiralita v skutočnosti svoju šifru zmenila už v novembri v roku 1803 potom, ako sa šifru z roku 1799 podarilo ukoristiť Francúzom a nová šifrovacia kniha bola Nelsonovmu loďstvu odovzdaná v Cádize v septembri 1805.
