England expects that every man will do his duty

"England expects that every man will do his duty" was a signal sent by Vice Admiral Horatio Nelson, 1st Viscount Nelson, from his flagship HMS Victory as the Battle of Trafalgar was about to commence on 21 October 1805. Trafalgar was a decisive naval engagement of the Napoleonic Wars. It gave the United Kingdom control of the seas, removing all possibility of a French invasion and conquest of Britain. Although there was much confusion surrounding the wording of the signal in the aftermath of the battle, the significance of the victory and Nelson's death during the battle led to the phrase becoming embedded in the English psyche, and it has been regularly quoted, paraphrased and referenced up to the modern day.

As the British fleet closed with the opposing combined fleets of France and Spain, Lord Nelson signalled all the necessary battle instructions to his ships. Aware of the momentousness of events to come, Lord Nelson felt that something extra was required. He instructed his signal officer, Lieutenant John Pasco, to signal to the fleet, as quickly as possible, the message "England confides that every man will do his duty." Pasco suggested to Nelson that expects be substituted for confides (i.e. is confident), since the former word was in the signal book, whereas confides would have to be spelt out letter-by-letter. Nelson agreed to the change (even though it produced a less trusting impression):

His Lordship came to me on the poop, and after ordering certain signals to be made, about a quarter to noon, he said, 'Mr. Pasco, I wish to say to the fleet, ENGLAND CONFIDES THAT EVERY MAN WILL DO HIS DUTY' and he added 'You must be quick, for I have one more to make which is for close action.' I replied, 'If your Lordship will permit me to substitute the confides for expects the signal will soon be completed, because the word expects is in the vocabulary, and confides must be spelt,' His Lordship replied, in haste, and with seeming satisfaction, 'That will do, Pasco, make it directly.'
