Kolin (Seven Years' War).
Fought June 18, 1757, between 34,000 Prussians, under Frederick the Great, and 54,000 Austrians, under Marshal Daun. Daun occupied the heights between Kolin and Chotzewitz, where he was attacked by Frederick, who had nearly succeeded in turning his right flank when the Prussian right broke and fled. The Prussian cavalry charged gallantly six times, but could make no impression on the Austrian defence, and Frederick was beaten back with a loss of 14,000 men and 43 guns. The Austrians lost 9,000.
