Rufus, the governor of Germany, set out to make war on Vindex; but when he reached Vesontio, he proceeded to besiege the city, for the alleged reason that it had not received him. But Vindex came to the aid of the city against him and encamped not far off, whereupon they sent messages back and forth to each other and finally held a conference by themselves at which no one else was present and came to a mutual agreement against Nero, as was conjectured.

Notes :
The army of Rufus, seemingly not being aware of the agreement their leader had made with Vindex, attacked the latters army, described in: "The army of Verginius Rufus attacks and kills many of the army of Vindex, believing them to be enemies."
