Dum haec aguntur in Thraciis, Gratianus docto litteris patruo, qua industria superaverit Alamanos, pedestri itinere praemissis impedimentis et sarcinis, ipse cum expeditiore militum manu, permeato Danubio, delatus Bononiam, Sirmium introiit, et quadriduum ibi moratus, per idem flumen ad Martis castra descendit, febribus intervallatis afflictus: in quo tractu Halanorum impetu repentino temptatus, amisit sequentium paucos.
While this was going on in Thrace, Gratian, having informed his uncle by letter with what energy he had overthrown the Alamanni, sent on ahead by land all his baggage and packs, and descending the Danube with a band of light-armed troops, came to Bononia and entered Sirmium. Having delayed there for four days, he went on over the same river to the Camp of Mars, although at tacked by intermittent fevers. In that region the Halani unexpectedly fell upon him, and he lost a few of his followers.
