On the 5th December, Buonaparte was at Smorgoni, where he again received a welcome reinforcement, being joined by Loison, advancing at the head of the garrison of Wilna, to protect his retreat to that place, and whose opportune assistance gave a new rear-guard, to supply that commanded by Maison, which the war and weather had already rendered as incapable of effectual service as those whom they had protected from the banks of the Beresina to Smorgoni. Loison had orders to take in his turn this destructive duty, for which purpose he was to remain a day's march, as usual, behind the mass of what had been the army. The order of the march to Wilna thus arranged, Napoleon determined on his own departure. Three sledges were provided; one of which was prepared to carry him and Caulaincourt, whose title the Emperor proposed to assume while travelling incognito, although their figures were strikingly dissimilar, the Duke of Vicenza being a tall, raw-boned, stiff-looking man. In a general audience, at which were present the King of Naples, the viceroy, Berthier, and the maréchals, Napoleon announced to them that he had left Murat to command the army, as generalissimo. He talked to them in terms of hope and confidence. He promised to check the Austrians and Prussians in their disposition for war, by presenting himself at the head of the French nation, and 1,200,000 men;--he said he had ordered Ney to Wilna, to re-organise the army, and to strike such a blow as should discourage the advance of the Russians;--lastly, he assured them of winter-quarters beyond the Niemen. He then took an affectionate and individual farewell of each of his generals, and, stepping into his traineau, a lively emblem of the fishing-boat of Xerxes, he departed from Smorgoni at the late hour of ten at night.[224]
