It was only when Bonaparte had returned to France from his long campaign in Poland that the affairs of the Iberian Peninsula began to come seriously to the front. The Emperor arrived in Paris at the end of July, 1807, and this was the moment at which he might have been expected to produce the rod, for the chastisement which the rulers of Spain had merited by their foolish proclamation of the preceding year. But no sign of any such intention was displayed: it is true that early in August French troops in considerable numbers began to muster at Bayonne[12], but Bonaparte openly declared that they were destined to be used, not against Spain, but against Portugal. One of the articles of the Peace of Tilsit had been to the effect that Sweden and Portugal, the last powers in Europe which had not submitted to the Continental System, should be compelled--if necessary by force--to adhere to it, and to exclude the commerce of England from their ports. It was natural that now, as in 1801, a French contingent should be sent to aid Spain in bringing pressure to bear on her smaller neighbour. With this idea Godoy and his master persisted in the voluntary blindness to the signs of the times which they had so long been cultivating. They gave their ambassador in Lisbon orders to act in all things in strict conjunction with his French colleague. [12] The first notice of the ‘Corps of Observation of the Gironde’ is to be found in a dispatch of Masserano, the Spanish ambassador at Paris, dated July 30, which gives notice of the approaching concentration at Bayonne. But the quiet movement of troops in this direction had begun long before the Russian war was over.
