Monongahela (Seven Years' War).
Fought July 9, 1755, between 900 French and Indians, under Contrecœur, and about 1,400 British and Virginians, under Braddock. The English were attacked shortly after crossing the river, and though the officers and the Virginians fought gallantly, the troops, ignorant of Indian warfare, gave way to panic, and after three hours' fighting, were driven across the Monongahela, with a loss of 877 killed and wounded. Of 86 officers, 63 fell, including Braddock, who was mortally wounded. The French lost 16 only; their Indian allies somewhat more heavily.
