Four thousand nine hundred prisoners of war were taken, with fifty-one guns and 7000 pounds in money.
Three days later Frederick, with forty thousand men, was off; deceived Daun as to his intentions, entered Moravia, and besieged Olmuetz.

Keith was with him again, and Fergus had returned to his staff.

The march was conducted with the marvellous precision and accuracy that characterized all Frederick's movements, but Olmuetz was a strong place and stoutly defended.
The Prussian engineers, who did not shine at siege work, opened their trenches eight hundred yards too far away.

The magazines were too far off, and Daun, who as usual carefully abstained from giving battle, so cut up the convoys that, after five weeks of vain endeavours, the king was obliged to raise the siege; partly owing to the loss of the convoy that would have enabled him to take the town, which was now at its last extremity; and partly that he knew that the Russians were marching against Brandenburg.
He made a masterly retreat, struck a heavy blow at Daun by capturing and destroying his principal magazine, and then took up a very strong position near Koeniggraetz.

Here he could have maintained himself against all Daun's assaults, for his position was one that Daun had himself held and strongly fortified; but the news from the north was of so terrible a nature that he was forced to hurry thither.
The Cossacks, as the Russian army advanced, were committing most horrible atrocities; burning towns and villages, tossing men and women into the fire, plundering and murdering everywhere; and the very small Prussian force that was watching them was powerless to check the swarming marauders.
Frederick therefore, evading Daun's attempts to arrest his march, crossed the mountains into Silesia again.
