Napoleon's plan for the 27th was, as usual, simple in its outline. As at Friedland, a ravine separated a part of the hostile line of battle from the rest. The villages west of the Plauen ravine and even Löbda were occupied in the early morning by General Metzko with the leading division of Klenau's corps from Freiberg, and upon Metzko Napoleon intended first to throw the weight of his attack, giving to Victor's infantry and the cavalry of Murat, king of Naples, the task of overwhelming the isolated Austrians. The centre, aided by the defences of the Dresden suburbs, could hold its own, as the events of the 26th had shown, the left, now under Ney, with whom served Kellermann's cavalry and the Young Guard, was to attack Wittgenstein's Russians on the Pirna road. Thus, for once, Napoleon decided to attack both flanks of the enemy. His motives in so doing have been much discussed by the critics; Vandamme's movements, it may be suggested, contributed to the French emperor's plan, which if carried out would open the Pirna road. Still, the left attack may have had a purely tactical object, for in that quarter was the main body of the Prussians and Russians, and Napoleon's method was always to concentrate the fury of the attack on the heaviest masses of the enemy, i.e. the best target for his own artillery. A very heavy rainstorm during the night seriously affected the movements of troops on the following day, but all to Napoleon's advantage, for his more mobile artillery, reinforced by every horse available in and about Dresden, was still able to move where the Allied guns sank in mud. Further, if the cavalry had to walk, or at most trot, through the fields the opposing infantry was almost always unable to fire their muskets. "You cannot fire; surrender," said Murat to an Austrian battalion in the battle. "Never," they replied; "you cannot charge us." On the appearance of Murat's horse artillery, however, they had to surrender at once. Under such conditions, Metzko, unsupported either by Klenau or the main army beyond the ravine, was an easy victim. Victor from Löbda drove in the advanced posts and assaulted the line of villages Wolfnitz-Töltschen; Metzko had to retire to the higher ground S.W. of the first line, and Murat, with an overwhelming cavalry force from Cotta and Burgstädl, outflanked his left, broke up whole battalions, and finally, with the assistance of the renewed frontal attack of Victor's infantry, annihilated the division. The Austrian corps of Gyulai arrived too late to save it. A few formed bodies escaped across the ravine, but Metzko and three-fourths of his men were killed or taken prisoners.
