At the ill-governed realms of Spain and Portugal it is certain that he must have taken a specially long glance. He had against the house of the Bourbons the grudge that men always feel against those whom they have injured. He knew that they could never forgive the disappointed hopes of 1799, nor the murder of the Duc d’Enghien, however much they might disguise their sentiments by base servility. What their real feelings were might be guessed from the treacherous conduct of their kinsmen of Naples, whom he had just expelled from the Continent. The Bourbons of Spain were at this moment the most subservient and the most ill-used of his allies. Under the imbecile guidance of his favourite Godoy, Charles IV had consistently held to the league with France since 1795, and had thereby brought down untold calamities upon his realm. Nevertheless Napoleon was profoundly dissatisfied with him as an ally. The seventy-two million francs of subsidies which he was annually wringing from his impoverished neighbour seemed to him a trifle. The chief gain that he had hoped to secure, when he goaded Spain into war with England in 1804, had been the assistance of her fleet, by whose aid he had intended to gain the control of the narrow seas, and to dominate the Channel long enough to enable him to launch his projected invasion against the shores of Kent and Sussex. But the Spanish navy, always more formidable on paper than in battle, had proved a broken reed. The flower of its vessels had been destroyed at Trafalgar. There only remained in 1806 a few ships rotting in harbour at Cadiz, Cartagena, and Ferrol, unable even to concentrate on account of the strictness of Collingwood’s blockade. Napoleon was angry at his ally’s impotence, and was already reflecting that in hands more able and energetic than those of Charles IV Spain might give aid of a very different kind. In after years men remembered that as early as 1805 he had muttered to his confidants that a Bourbon on the Spanish throne was a tiresome neighbour--too weak as an ally, yet dangerous as a possible enemy[6]. For in spite of all the subservience of Charles IV the Emperor believed, and believed quite rightly, that a Bourbon prince must in his heart loathe the unnatural alliance with the child of the Revolution. But in 1806 Bonaparte had an impending war with Prussia on his hands, and there was no leisure for interfering in the affairs of the Peninsula. Spain, he thought, could wait, and it is improbable that he had formulated in his brain any definite plan for dealing with her. [6] See, for example, the very interesting story told by Marshal Jourdan in his _Mémoires_ (p. 9) of the long conversation which the emperor had with him at Verona on June 16, 1805: ‘Tant pour l’affermissement de ma dynastie que pour la sûreté de France,’ concluded Napoleon, ‘un Bourbon sur le trône d’Espagne est un voisin trop dangereux.’
