Buonaparte, well aware of the total irregularity of the proceedings in this extraordinary case, seems, on some occasions, to have wisely renounced any attempt to defend what he must have been convinced was indefensible, and has vindicated his conduct upon general grounds, of a nature well worthy of notice. It seems that, when he spoke of the death of the Duke d'Enghien among his attendants, he always chose to represent it as a case falling under the ordinary forms of law, in which all regularity was observed, and where, though he might be accused of severity, he could not be charged with violation of justice. This was safe language to hearers from whom he was sure to receive neither objection nor contradiction, and is just an instance of an attempt, on the part of a conscientiously guilty party, to establish, by repeated asseverations, an innocence which was inconsistent with fact. But with strangers, from whom replies and argument might be expected, Napoleon took broader grounds. He alleged the death of the Duke d'Enghien to be an act of self-defence, a measure of state policy, arising out of the natural rights of humanity, by which a man, to save his own life, is entitled to take away that of another. "I was assailed," he said, "on all hands by the enemies whom the Bourbons raised up against me; threatened with air-guns, infernal machines, and deadly stratagems of every kind. I had no tribunal on earth to which I could appeal for protection, therefore I had a right to protect myself; and by putting to death one of those whose followers threatened my life, I was entitled to strike a salutary terror into the others."[58] We have no doubt that, in this argument, which is in the original much extended, Buonaparte explained his real motives; at least we can only add to them the stimulus of obstinate resentment, and implacable revenge. But the whole resolves itself into an allegation of that state necessity, which has been justly called the Tyrant's plea, and which has always been at hand to defend, or rather to palliate, the worst crimes of sovereigns. The prince may be lamented, who is exposed, from civil disaffection, to the dagger of the assassin, but his danger gives him no right to turn such a weapon even against the individual person by whom it is pointed at him. Far less could the attempt of any violent partisans of the House of Bourbon authorise the first consul to take, by a suborned judgment, and the most precipitate procedure, the life of a young prince, against whom the accession to the conspiracies of which Napoleon complained had never been alleged, far less proved. In every point of view, the act was a murder; and the stain of the Duke d'Enghien's blood must remain indelibly upon Napoleon Buonaparte.
