The real cause of seizing the territories of an unoffending prince, who was totally helpless, unless in so far as right or justice could afford him protection, was Buonaparte's previous resolution, already hinted at, to incorporate Hesse-Cassel with the adjacent territories, for the purpose of forming a kingdom to be conferred on his youngest brother Jerome. This young person bore a gay and dissipated character; and, though such men may at times make considerable sacrifices for the indulgence of transient passion, they are seldom capable of retaining for a length of time a steady affection for an object, however amiable. Jerome Buonaparte, as before stated, had married an American young lady, distinguished for her beauty and her talents, and had thus lost the countenance of Napoleon, who maintained the principle, that segregated as his kindred were from the nation at large, by their connexion with him, his rank, and his fortunes, they were not entitled to enter into alliances according to the dictates of their own feelings, but were bound to form such as were most suitable to his policy. Jerome was tempted by ambition finally to acquiesce in this reasoning, and sacrificed the connexion which his heart had chosen, to become the tool of his brother's ever-extending schemes of ambition. The reward was the kingdom of Westphalia, to which was united Hesse-Cassel, with the various provinces which Prussia had possessed in Franconia, Westphalia Proper, and Lower Saxony; as also the territories of the unfortunate Duke of Brunswick. Security could be scarcely supposed to attend upon a sovereignty, where the materials were acquired by public rapine, and the crown purchased by domestic infidelity. About the middle of November, Mortier formally re-occupied Hanover in the name of the Emperor, and, marching upon Hamburgh, took possession of that ancient free town, so long the emporium of commerce for the north of Europe. Here, as formerly at Leipsic, the strictest search was made for British commodities and property, which were declared the lawful subject of confiscation. The _Moniteur_ trumpeted forth, that these rigorous measures were accompanied with losses to British commerce which would shake the credit of the nation. This was not true. The citizens of Hamburgh had long foreseen that their neutrality would be no protection, and, in spite of the fraudful assurances of the French envoy, designed to lull them into security, the merchants had availed themselves of the last two years to dispose of their stock, call in their capital, and wind up their trade; so that the rapacity of the French was in a great measure disappointed. The strict search after British property, and the confiscation which was denounced against it at Hamburgh and elsewhere, were no isolated acts of plunder and spoliation, but made parts of one great system for destroying the commerce of England, which was shortly after laid before the world by the celebrated decrees of Berlin.[253]
