ex Alamannis vero sex milia corporum numerata sunt, in campo constrata, et alii inaestimabiles mortuorum acervi per undas fluminis ferebantur.
Translation :
But of the Alamanni there were counted six thousand corpses lying on the field, and heaps of dead, impossible to reckon, were carried off by the waves of the river.
