Rosbach (Seven Years' War).
Fought November 5, 1757, between 80,000 French and Austrians, under Marshal Soubise, and 30,000 Prussians, under Frederick the Great. Frederick, who occupied the heights of Rosbach, was attacked by the allies. The Prussian cavalry, however, under Seidlitz, charged down upon the Austrians, and threw them into disorder, and the infantry falling upon the broken columns utterly routed them, with a loss of 4,000 killed and wounded, 7,000 prisoners, including 11 generals and 63 guns. The Prussians lost 3,000 only.
