The London Star of the 11th of April, says, The murder of the Duke d'Enghien by the French tyrant must excite the general indignation of Europe. A private letter received by the mail of yesterday from Hamburg says, the news of this atrocious deed excited there, among people of every opinion in politics a sensation of indignation and horror which no language can describe. "The indecent haste (says the writer) with which the sentence was executed, is of itself, in the minds of all reasonable people, a sufficient proof that it was unjust. Not to mention the violation of the rights of a neutral territory, it is sufficiently clear, that the French Government having long ago deprived the whole family of their Sovereign of the rights of Citizens, no individual of that family can be condemned by a law, which is posterior to this deprivation, and made against French citizens alone. By the same rule they could and ought to shoot every Englishman or person of any other nation whatever, whom they took in arms against France, or who even, at any time in his life, had ever been concerned in the formation or execution of any plan whatever, of the nature of those mentioned in the act of accusation against the Duke: they might as justly require all foreign powers to deliver up to them all Englishmen, now residing in their territory, who are or ever have been agents of the English Government, or have borne arms against France, or might even send troops, as many as they should think necessary to arrest all such persons, and conduct them to Paris to be murdered, after a mock trial of a few hours. The proceeding, with regard to the Prince, as impolitic as it is unjust, is to be regarded as an ebullition of the savage rage of slaves, who have taken the places of their Masters: of men, disappointed in the effect of their gasconading threats, and seizing the first opportunity of satiating with security the transports of their impotent fury. Not any part the prince may or may not have had in the conspiracy (if ever it existed), but the rage of Bonaparte at seeing all his threats against England despised, his vaunted preparations useless, and himself in the disagreeable alternative of suffering the contempt of Europe, or undertaking the expedition which he now sees must fall, has brought the Prince to this untimely death."
