In using the Trafalgar campaign as a basis for a novel I have not consciously meddled with history. All the major events actually took place and many of the characters existed. I have used a novelist's freedom in interpreting the actions of some of these, such as Camelford, who remains an enigma to this day. As for the others, I have used their written or recorded words or opinions to preserve historical accuracy.
There is no doubt that Napoleon's intention to invade Great Britain some time between 1803 and 1805 was very real indeed. That he swung his army away from the Channel to defeat Austria and Russia does not diminish that intent; it merely illustrates his disillusion with his admirals, an understandable desire to secure his rear after the formation of the Third Coalition, and the strategic adaptability of his genius.
A great deal has been written about Trafalgar and its consequences. Perhaps the most lamentable of these is an improper appreciation of our opponents. It was this reflection that attracted me to the character of Pierre de Villeneuve, the noble turned republican, whose abilities have been entirely eclipsed by the apotheosis of Nelson. It was Villeneuve's prescience that made him the 'coward' his contemporaries took him for. Ten months before the battle, Villeneuve outlined the precise method by which Nelson would attack. Realising this and the comparative qualities of the two fleets, Villeneuve was astute enough to foresee the likely outcome of action, notwithstanding his plan for a counter-attack. Of his personal courage or that of his fleet, there is no doubt. I hope I have done justice to their shades.
None of these assertions detract from the British achievement; quite the contrary. The Battle of Trafalgar remains the completest example of annihilation of a battlefleet until the Japanese attack on Pearl Harbor. Nevertheless there were grave misgivings about Nelson's ideas of how a blockade ought to be conducted, and these were freely expressed at the time. History vindicated Nelson, but contemporary opinion was not always so kind, and French officers like Santhonax wanted to exploit what was held to be a weakness. Napoleon always disclaimed any part in the death of John Wesley Wright and profoundly regretted that of D'Enghien. Between denial and admission lie a number of other mysterious deaths, particularly that of Pierre de Villeneuve. Despite the official verdict of suicide, I find it inconceivable that Villeneuve stabbed his own heart six times and I have laid the blame elsewhere. As to Villeneuve's curious letter of denunciation, one authority states that such a document of unproven origin came to light among the papers of a British diplomat employed at the time. It seemed to me that it might have formed some part of those supplementary revelations of unrecorded history which the adventures of Nathaniel Drinkwater have exposed.
