The mismanagement of the Prussian generals in these calamitous battles, and in all the manœuvres which preceded them, amounted to infatuation. The troops also, according to Buonaparte's evidence, scarcely maintained their high character, oppressed probably by a sense of the disadvantages under which they combated. But it is unnecessary to dwell on the various causes of a defeat, when the vanquished seem neither to have formed one combined and general plan of attack in the action, nor maintained communication with each other while it endured, nor agreed upon any scheme of retreat when the day was lost. The Duke of Brunswick, too, and General Schmettau, being mortally wounded early in the battle, the several divisions of the Prussian army fought individually, without receiving any general orders, and consequently without regular plan or combined manœuvres. The consequences of the defeat were more universally calamitous than could have been anticipated, even when we consider, that no mode of retreat having been fixed on, or general rallying place appointed, the broken army resembled a covey of heathfowl, which the sportsman marks down and destroys in detail and at his leisure. Next day after the action, a large body of the Prussians, who, under the command of Mollendorf had retired to Erfurt, were compelled to surrender to the victors, and the marshal, with the Prince of Orange Fulda, became prisoners. Other relics of this most unhappy defeat met with the same fate. General Kalkreuth, at the head of a considerable division of troops, was overtaken and routed in an attempt to cross the Hartz mountains. Prince Eugene of Wirtemberg commanded an untouched body of sixteen thousand men, whom the Prussian general-in-chief had suffered to remain at Memmingen, without an attempt to bring them into the field. Instead of retiring when he heard all was lost, the prince was rash enough to advance towards Halle, as if to put the only unbroken division of the Prussian army in the way of the far superior and victorious hosts of France. He was accordingly attacked and defeated by Bernadotte. [Sidenote: PRINCE HOHENLOE--BLUCHER.]
