The determining factor in his subsequent action was undoubtedly supplied in the autumn of 1806 by the conduct of the Spanish government during the campaign of Jena. There was a moment, just before that decisive battle had been fought, during which European public opinion was expecting a check to the French arms. The military prestige of Prussia was still very great, and it was well known that Russia had not been able to put forth her full strength at Austerlitz. Combined it was believed that they would be too much for Napoleon. While this idea was still current, the Spanish king, or rather his favourite Godoy, put forth a strange proclamation which showed how slight was the bond of allegiance that united them to France, and how hollow their much vaunted loyalty to the emperor[7]. It was an impassioned appeal to the people of Spain to take arms _en masse_, and to help the government with liberal gifts of men, horses and money. ‘Come,’ it said, ‘dear fellow countrymen, come and swear loyalty beneath the banners of the most benevolent of sovereigns.’ The God of Victories was to smile on a people which helped itself, and a happy and enduring peace was to be the result of a vigorous effort. It might have been pleaded in defence of Charles IV that all this was very vague, and that the anonymous enemy who was to be crushed might be England. But unfortunately for this interpretation, three whole sentences of the document are filled with demands for horses and an instant increase in the cavalry arm of the Spanish military establishment. It could hardly be urged with seriousness that horsemen were intended to be employed against the English fleet. And of naval armaments there was not one word in the proclamation. [7] For the full text of this bombastic appeal see Appendix, No. I. Godoy speaks throughout in his own name, not in that of his master.
