The year 70 started with the odds favoring the rebels. Two legions were still besieged at Castra Vetera and the rest of the Roman army was not large enough to cope with the revolt. Apart from the Batavian rebellion, the Trevirans and Lingones had declared the independence of Gaul. Julius Sabinus, the rebel emperor, managed to persuade the I "Germanica" and XVI "Gallica" to come over to his side. At Castra Vetera the situation was desperate. Food supplies had run out and the besieged legions were eating horses and mules to survive. With no prospect of a relief, the commander of the troops, Munius Lupercus, decided to surrender.
