Ariovistus on the Middle Rhine
The war was prolonged for some years with varying success; on the whole the results were unfavourable to the Haedui. Their leader Eporedorix at length called out their whole clients, and marched forth with an enormous superiority of force against the Germans. These obstinately refused battle, and kept themselves under cover of morasses and forests. It was not till the clans, weary of waiting, began to break up and disperse, that the Germans appeared in the open field, and then Ariovistus compelled a battle at Admagetobriga, in which the flower of the cavalry of the Haedui were left on the field.
The Haedui, forced by this defeat to conclude peace on the terms which the victor proposed, were obliged to renounce the hegemony, and to consent with their whole adherents to become clients of the Sequani; they had to bind themselves to pay tribute to the Sequani or rather to Ariovistus, and to furnish the children of their principal nobles as hostages; and lastly they had to swear that they would never demand back these hostages nor invoke the intervention of the Romans.
