Even before the reports had been published in Europe’s newspapers Napoleon had settled the affairs of Charles and Ferdinand. The latter was sent into exile at Talleyrand’s estate at Valençay, to spend his remaining days under close watch. He would live comfortably enough, but in isolation from the rest of society and his countrymen. Charles, meanwhile, had hardened his position and negotiated a much better deal than his son received. A number of estates in France and an annual pension of some seven and a half million francs was the price he demanded for surrendering any claim to his former kingdom.

Napoleon announced to Europe that Murat would remain in charge of the government in Spain until a new ruler was chosen. Again Napoleon approached Louis, who once more refused to abandon his palace in Holland, and so the Emperor turned to his older brother, Joseph.

One day, soon after the conference at Bayonne had ended, Napoleon and his staff, together with his brothers, went out to shoot in the surrounding countryside. Berthier had learned from his experience with the rabbits and made sure that this time there would be no question of the event’s turning into a farce. It was early in May and the first growths of spring were bursting from every tree, while new flowers sprinkled bright colours across the rolling, verdant countryside. Birds sang lustily in the trees, little knowing that the band of laughing men passing beneath them in open carriages would shortly be turning their guns on any feathered prey that came into their field of vision.

The hunting party arrived at the site chosen for the shoot: a small hillock overlooking an expanse of flat, marshy ground.A light buffet had been prepared, and Napoleon chewed on a savoury game pie as he spoke to his brother, who was sitting beside him on a grassy bank.

‘Joseph, you will recall the conversation we had about what might happen should the throne of Spain fall vacant.’

‘I recall it very well,’ Joseph replied flatly.

‘Well, what do you say to my offer now?’

‘It is very generous of you, but I am not sure that I am the right man to rule Spain. Besides, I am in the midst of reforming the government of Naples. It is a task I must complete if we are to win the people over.’

‘That work can be easily continued by another,’ Napoleon said dismissively. ‘And you would have the chance to improve a much more significant country. In time your reforms could make Spain a great power once again.You would be loved by the people and envied for their affection by many of the other rulers in Europe.What say you?’
