But Frederick had prepared for such a stroke; and had placed Draisen, with the left wing of the cavalry, in a hollow sheltered from the fire of the Austrian batteries, and bade him do nothing, attempt nothing, but cover the right flank of the infantry from the Austrian horse.

He accordingly let Lucchesi charge down with his cavalry, and then rushed out on his rear, and fell suddenly and furiously upon him.
Astounded at this sudden and unexpected attack, and with their ranks swept by a storm of Prussian bullets, the Austrian cavalry broke and fled in all directions, Lucchesi having paid for his fault by dying, fighting to the last.

His duty thus performed, Draisen was free to act, and fell upon the flank and rear of the Austrian infantry; and in a few minutes the battle was over, and the Austrians in full retreat.
They made, however, another attempt to stand at Saara; but it was hopeless, and they were soon pushed backwards again and, hotly pressed, poured over the four bridges across the Schweidnitz river, and for the most part continued their flight to Breslau.

Until the Austrians had crossed the river the Prussian cavalry were on their rear, sabring and taking prisoners, while the infantry were halted at Saara, the sun having now set.
Exhausted as they were by their work, which had begun at midnight and continued until now without pause or break, not yet was their task completely done.

The king, riding up the line, asked if any battalion would volunteer to follow him to Lissa, a village on the river bank.
