In the course of the night, Buonaparte was joined by Macdonald, Oudinot, and Gerard, with the forces with which they had lately held the defensive upon the Seine; and the anxious question remained, whether, thus reinforced, he should venture an action with the grand army, to which he was still much inferior in numbers. Schwartzenberg, agreeably to the last resolution of the allies, drew up on the heights of Mesnil la Comtesse, prepared to receive battle. On consideration of the superior strength of the enemy, and of the absence of some troops not yet come up, Napoleon finally determined not to accept a battle under such disadvantageous circumstances. He therefore commenced a retreat, the direction of which was doomed to prove the crisis of his fate. He retired as he had advanced, along both sides of the Aube; and though pursued and annoyed in this movement (which was necessarily executed through Arcis and all its defiles,) his rear-guard was so well conducted, that he sustained little loss. A late author,[11] who has composed an excellent and scientific work on this campaign, has remarked--"In concluding the account of the two days thus spent by the contending armies in presence of each other, it is equally worthy of remark, that Buonaparte, with a force not exceeding 25,000 or 30,000 men, should have risked himself in such a position in front of 80,000 of the allies, as that the latter should have allowed him to escape them with impunity." The permitting him to retreat with so little annoyance has been censured in general by all who have written on this campaign.[12] FOOTNOTES: [1] See _ante_, vol. iv., p. 356. [2] Moniteur, March 11.
