Katzbach (Campaign of Leipsic).
Fought August 26, 1813, between the French, under Macdonald, and the Prussians, under Blucher. Macdonald crossed the Katzbach, and while waiting for his left wing and cavalry under Souham, was attacked by Blucher, and driven back. As Macdonald was retiring Souham appeared on the field, but before he could deploy he was attacked and routed with great slaughter, while the centre under Lauriston also suffered severely in recrossing the river. The French lost 15,000 killed and wounded, and over 100 guns.
