In the next year the meaning of the French alliance was revealed in the Treaty of St. Ildefonso, which required Spain to furnish troops, ships, and subsidies for the war against England, a state of vassalage which was made harder by Napoleon.  The results are well known.  After being forced by him to cede Trinidad to us at the Peace of Amiens, she sacrificed her navy at Trafalgar, saw her colonies and commerce decay and her finances shrivel for lack of the golden streams formerly poured in by Mexico and Peru.

In the summer of 1806, while sinking into debt and disgrace, the Court of Madrid heard with indignation of Napoleon’s design to hand over the Balearic Isles to the Spanish Bourbons whom he had driven from Naples and proposed to drive from Sicily.  At once Spanish pride caught fire and clutched at means of revenge.[182] Godoy was further incensed by the sudden abandonment of the plans which he had long discussed with Napoleon for the partition of Portugal, plans which gave him the prospect of reigning as King over the southern portion of that realm.[183] Accordingly, when the Emperor was entering upon the Jena campaign, he summoned the Spanish people to arms in a most threatening manner.  The news of the collapse of Prussia ended his bravado.  Complaisance again reigned at Madrid, and 15,000 Spaniards were sent, at Napoleon’s demand, to serve on the borders of Denmark, while the autocrat of the West perfected his plans against the Iberian Peninsula.  As was noted in the previous chapter, the Emperor renewed his offers of a partition of Portugal in the early autumn of 1807; and in pursuance of the secret Treaty of Fontainebleau, Junot’s corps marched through Spain into Portugal, where they were helped by a Spanish corps.

It is significant that, as early as October 17th, 1807, Napoleon ordered his general to send a detailed description of the country and of his line of march, the engineer officers being specially charged to send sketches, “which it is important to have.”  Other French divisions then crossed the Pyrenees, under plea of keeping open Junot’s communications with France; and spies were sent to observe the state of the chief Spanish strongholds.  Others were charged to report on the condition of the Spanish army and the state of public opinion; while Junot was cautioned to keep a sharp watch on the Spanish troops in Portugal, to allow no fortress to be in their hands, and to send all the Portuguese troops away to France.  Thus, in the early days of 1808, Napoleon had some 20,000 troops in Portugal, about 40,000 in the north of Spain, and 12,000 in Catalonia.  By various artifices they gained admission into the strongholds of Pamplona, Monjuik, Barcelona, St. Sebastian, and Figueras, so that by the month of March the north and west of the peninsula had passed quietly into his hands, while the greater part of the Spanish army was doing his work in Portugal or on the shores of the Baltic.[184]
