ten at night
They had all but won . Frederick in vain tried to rally and lead them afresh to the attack . They had done all that men could do , and the battle ceased . Daun scarcely attempted to pursue , and the Prussians marched away , unmolested even by cavalry ; some of the regiments remaining firm in their position until nightfall , repulsing with great loss the one attempt of the Austrians at pursuit ; and Ziethen 's cavalry did not draw off until ten at night . The Austrians had 60,000 men in the field , of whom they lost in killed and wounded 8114 . The Prussians , who began the day 34,000 strong , lost 13,773 ; of whom the prisoners , including all the wounded , amounted to 5380 . The news of the disaster , and with it Frederick 's order to prepare to raise the siege of Prague at once , came like a thunderclap upon the Prussian camp .
