The fate which Mr. Drake dreaded, and perhaps narrowly escaped, actually befell Sir George Rumbold, resident at the free German city of Hamburgh, in the capacity of his British Majesty's envoy to the Circle of Lower Saxony. On the night of the 25th October, he was seized, in violation of the rights attached by the law of nations to the persons of ambassadors, as well as to the territories of neutral countries, by a party of the French troops, who crossed the Elbe for that purpose. The envoy, with his papers, was then transferred to Paris in the capacity of a close prisoner, and thrown into the fatal Temple. The utmost anxiety was excited even amongst Buonaparte's ministers, lest this imprisonment should be intended as a prelude to further violence; and both Fouché and Talleyrand exerted what influence they possessed over the mind of Napoleon, to prevent the proceedings which were to be apprehended. The King of Prussia also extended his powerful interposition; and the result was, that Sir George Rumbold, after two days' imprisonment, was dismissed to England, on giving his parole not to return to Hamburgh. It seems probable, although the _Moniteur_ calls this gentleman the worthy associate of Drake and Spencer Smith, and speaks of discoveries amongst his papers which were to enlighten the public on the policy of England, that nothing precise was alleged against him, even to palliate the outrage which the French ruler had committed. The tenor of Buonaparte's conduct in another instance, towards a British nobleman of distinction, though his scheme was rendered abortive by the sagacity of the noble individual against whom it was directed, is a striking illustration of the species of intrigue practised by the French police, and enables us to form a correct judgment of the kind of evidence upon which Buonaparte brought forward his calumnious accusation against Britain and her subjects.
