The negotiation for this important pacification was not conducted in the usual style of diplomacy, but in that which Napoleon had repeatedly shown a desire to substitute for the conferences of inferior agents, by the intervention, namely, of the high-contracting parties in person. The armistice was no sooner agreed upon, than preparations were made for a personal interview betwixt the two Emperors.[281] It took place upon a raft prepared for the purpose, and moored in the midst of the river Niemen, which bore an immense tent or pavilion. At half-past nine, 25th June, 1807, the two Emperors, in the midst of thousands of spectators, embarked at the same moment from the opposite banks of the river. Buonaparte was attended by Murat, Berthier, Bessières, Duroc, and Caulaincourt; Alexander, by his brother the Archduke Constantine, Generals Bennigsen and Ouwarrow, with the Count de Lieven, one of his aides-de-camp. Arriving on the raft, they disembarked and embraced, amid the shouts and acclamations of both armies, and entering the pavilion which had been prepared, held a private conference of two hours. Their officers, who remained at a distance during the interview, were then reciprocally introduced, and the fullest good understanding seemed to be established between the sovereigns, who had at their disposal so great a portion of the universe.[282] It is not to be doubted, that on this momentous occasion Napoleon exerted all those personal powers of attraction, which, exercised on the part of one otherwise so distinguished, rarely failed to acquire the good-will of all with whom he had intercourse, when he was disposed to employ them.[283] He possessed also, in an eminent degree, the sort of eloquence which can make the worse appear the better reason, and which, turning into ridicule the arguments derived from general principles of morality or honesty, which he was accustomed to term idiosyncrasy, makes all reasoning rest upon existing circumstances. Thus, all the maxims of truth and honour might be plausibly parried by those arising out of immediate convenience; and the direct interest, or what seemed the direct interest, of the party whom he wished to gain over, was put in immediate opposition to the dictates of moral sentiment, and of princely virtue. In this manner he might plausibly represent, in many points, that the weal of Alexander's empire might require him to strain some of the maxims of truth and justice, and to do a little wrong in order to attain a great national advantage.
