His excuse for the treachery as expressed at the time was as follows: "My action is not good from a certain point of view, I know. But my policy demands that I shall not leave in my rear, so near to Paris, a dynasty hostile to mine." From this and from other similar remarks, it would seem that his resolve to dethrone the Bourbons was taken while on his march to Jena, but was thrust down into the abyss of his inscrutable will for a whole year, until Junot's march to Lisbon furnished a safe means for effecting the subjugation of Spain. This end he thenceforth pursued unswervingly with no sign of remorse, or even of hesitation--unless we accept as genuine the almost certainly spurious letter of March 29th, 1808. That letter represents him as blaming Murat for entering Madrid, when he had repeatedly urged him to do so; as asking his advice after he had all along kept him in ignorance as to his aims; and as writing a philosophical homily on the unused energies of the Spanish people, for whom in his genuine letters he expressed a lofty contempt.[192] The whole enterprise is, indeed, a masterpiece of skill, but a masterpiece marred by ineffaceable stains of treachery. And at the close of his life, he himself said: "I embarked very badly on the Spanish affair, I confess: the immorality of it was too patent, the injustice too cynical, and the whole thing wears an ugly look since I have fallen; for the attempt is only seen in its hideous nakedness deprived of all majesty and of the many benefits which completed my intention." That he hoped to reform Spain is certain. Political and social reforms had hitherto consolidated the work of conquest; and those which he soon offered to the Spaniards might possibly have renovated that nation, had they not been handed in at the sword's point; but the motive was too obvious, the intervention too insulting, to render success possible with the most sensitive people in Europe. On May 2nd he wrote to Murat that he intended King Joseph of Naples to reign at Madrid, and offered to Murat either Portugal or Naples.[193] He chose the latter. Joseph was allowed no choice in the matter. He was summoned from Naples to Bayonne, and, on arriving at Pau, heard with great surprise that he was King of Spain. Napoleon's selection was tactful. At Naples, the eldest of the Bonapartes had effected many reforms and was generally popular; but the treachery of Bayonne blasted all hopes of his succeeding at Madrid. Though the grandees of Spain welcomed the new monarch with courtly grace, though Charles IV. gave him his blessing, though Ferdinand demeaned himself by advising his former subjects quietly to submit, the populace willed otherwise.
