The army of the King thence marched to Eulenburg. The Austrian troops that had encamped in that vicinity retired, through Mochrena to Torgau, with so much precipitate haste that they abandoned a part of their tents. The army encamped with the right at Thalwitz and the left at Eulenburg. Hulsen was obliged to pass the Mulde with some battalions. He took a position between Belzen and Gostevra, opposite the Prince de Deuxponts, whose army was at Taucha. Under the present circumstances the first thing necessary was to drive the troops of the circles to a distance, as well because they were on the rear of the Prussians as to prevent their union with the Austrians. This cost but little trouble; Hulsen gave them the alarm, and they decamped the same night, passed the Pleisse, and then the Elster, and retreated to Zeitz. Major Quintus, with his free battalion, vigorously charged their rear-guard; from which he took four hundred prisoners. After so happily terminating this expedition, the Prussians recovered possession of Leipsic, and Hulsen rejoined the army. Every event hitherto (November) had turned to the advantage of the King. The irruption of the Russians and the taking of Berlin, which might appear to induce consequences so great, ended in a manner less afflicting than could have been expected. Contributions and money only were lost. The enemy was driven from the frontiers of Brandenburg. Wittenberg and Leipsic were recovered; and the troops of the circle were repulsed to a distance too considerable for it to be feared they should join the Imperialists with promptitude; but all was not yet done, and the projects that remained were the most difficult part of the whole. The Russians kept at Landsberg on the Wartha and there might remain peaceful spectators of what should pass in Saxony. The King, however, was informed that other reasons engaged them not to march to too great a distance; for their design was, should the Austrians obtain any advantages over the army of the King, or should Marshal Daun maintain Torgau, to reënter the electorate of Brandenburg, and, conjointly with the Austrians, to take up their quarters on the banks of the Elbe. The consequence of such a project would have been fatally desperate to Prussia. By this position they would cut off the army, not only from Silesia and Pomerania, but from Berlin itself--that nursing mother which supplied clothing, arms, baggage, and every necessary for the men. Add to which the troops would have no quarters to take except beyond the Mulde, between the Pleisse, the Saale, the Elster, and the Unstrut. This would have been a space too narrow to supply the army with subsistence through the winter. And whence should magazines for the spring, uniforms, and recruits be obtained? The army thus pressed, and thrown back upon the allies, would have starved them by starving itself.
