When the Bourbons of Spain saw that the British Government had succeeded in forming a new alliance against Napoleon, which would compel the French Emperor to take his armies hundreds of leagues north to struggle against the united armies of Prussia and Russia, it was thought that Napoleon must inevitably fall. Spain decided again to make common cause with the Allies, as we have before mentioned. A vehement proclamation was issued, calling the Spaniards to arms. The utter crushing of Prussia on the fields of Jena and Auerstadt literally frightened Spain out of her wits. She sent an ambassador extraordinary to _congratulate Napoleon upon his victory, and to assure him of the continued friendship of the Spanish Government_. Napoleon concealed his just resentment. The time to rectify the wrong had not yet come. Queen Caroline, the wife of Charles IV. of Spain, was one of the most infamous of women; still she could not be worse than her husband. There was a very handsome young fellow in the body-guard, named Godoy. Caroline fell in love with him, made him her intimate friend, lavished upon him titles and wealth and posts of responsibility. He was called the Prince of Peace, in consequence of the agency he had in effecting the treaty of Basle. He was in all respects a very weak and worthless creature, but he had become in reality the sovereign of Spain, governing with unlimited power. This man, in his anxiety to disarm the anger of Napoleon, sent an ambassador to the Emperor to renew his pledges of friendship, and to give assurance of his entire submission in all things to Napoleon's will. A secret treaty was accordingly made on the 27th of October, 1807, which enabled Napoleon, among other concessions, to station large bodies of French troops within the Spanish territory. The King's eldest son, Ferdinand, the heir to the throne, was then twenty-five years of age, and bore the title of the Prince of Asturias. His mother had truly characterized him as having "a mule's head and a tiger's heart." He hated Godoy, and was accused of attempting to poison his father and mother, that he might get the crown. His arrest and threatened execution by his father roused the masses of Madrid to a fury of insurrection. Much as they detested Ferdinand, they hated still more implacably the King and Queen, and the Queen's infamous paramour, Godoy. A raging insurrection swept the streets of Madrid. The King was terror-stricken, and implored help from Napoleon. He wrote: "SIRE, MY BROTHER,--I have discovered with horror that my eldest son, the heir presumptive to the throne, has not only formed the design to dethrone me, but even to attempt the life of myself and his mother. Such an atrocious attempt merits the most exemplary punishment. I pray your Majesty to aid me by your light and council."
