In fact, while Ney was attacking, Murat scoured his flanks with his cavalry, without being able to bring it into action; woods on the left, and morasses on the right, obstructed his movements.  But while they were fighting in front, both were anticipating the effect of a flanking march of the Westphalians, commanded by Junot.

From the Stubna, the high-road, in order to avoid the marshes formed by the various tributary streams of the Dnieper, turned off to the left, ascended the heights, and went farther from the basin of the river, to which it afterwards returned in a more favourable situation.  It had been remarked that a by-road, bolder and shorter, as they all are, ran straight across these low marshy grounds, between the Dnieper and the high-road, which it rejoined behind the plateau of Valoutina.

It was this cross-road which Junot pursued after crossing the river at Prudiszy.  It soon led him into the rear of the left of the Russians, upon the flank of the columns which were returning to the assistance of their rear-guard.  His attack was all that was wanted to render the victory decisive.  Those who were engaged in front with Marshal Ney would have been daunted at hearing an attack in their rear; while the uncertainty and disorder into which, in the midst of an action, it would have thrown the multitude of men, horses, and carriages, crowded together in one road, would have been irreparable; but Junot, though personally brave, was irresolute as a general.  His responsibility alarmed him.

Meanwhile Murat, judging that he must have come up, was astonished at not hearing his attack.  The firmness of the Russians opposed to Ney led him to suspect the truth.  He left his cavalry, and crossing the woods and marshes almost alone, he hastened to Junot, and upbraided him with his inaction.  Junot alleged in excuse, that “He had no orders to attack; his Wurtemberg cavalry was shy, its efforts feigned, and it would never be brought to charge the enemy’s battalions.”

These words Murat answered by actions.  He rushed on at the head of that cavalry, which, with a different leader, were quite different troops; he urged them on, launched them against the Russians, overthrew their tirailleurs, returned to Junot and said to him, “Now finish the business:  your glory and your marshal’s staff are still before you!” He then left him to rejoin his own troops, and Junot, confounded, remained motionless.  Too long about Napoleon, whose active genius directed every thing, both the plan and the details, he had learned only to obey:  he wanted experience in command; besides, fatigue and wounds had made him an old man before his time.

That such a general should have been selected for so important a movement, was not at all surprising; it was well known that the emperor was attached to him both from habit, (for he was his oldest aid-de-camp) and from a secret foible, for as the presence of that officer was mixed up with all the recollections of his victories and his glory, he disliked to part from him.  It is also reasonable to suppose that it flattered his vanity, to see men who were his pupils commanding his armies; and it was moreover natural that he should have a firmer alliance on their attachment, than on that of any others.
