eleven o'clock
Frederick and Schwerin spent much time in surveying the position , and agreed that on two sides the Austrian position was absolutely impregnable ; but that on the right flank , attack was possible . Schwerin would fain have waited until the next morning , since his troops were fatigued by their long marches , and had been on foot since midnight . The Austrians , however , were expecting a reinforcement of thirty thousand men , under Daun , to join them hourly ; and the king therefore decided on an attack , the terrible obstacles presented by the swamps being altogether unnoticed . With incredible speed the Prussians moved away to their left , and by eleven o'clock were in readiness to attack the right flank of the Austrian position . Browne , however , was in command here and , as soon as the intention of the Prussians was perceived , he swung back the right wing of the army at right angles to its original position , so that he presented a front to the Prussian attack ; massing thickly at Sterbold , a village at the edge of the swamps . Rapidly the whole of the artillery and cavalry were formed up on this face and , quick as had been the advance of the Prussians , the Austrians were perfectly ready to meet them . Led by General Winterfeld , the Prussians rushed forward ; but as they advanced , a terrific artillery fire was opened upon them .
