o his force a thousand
picked men from the Fifth and Fifteenth legions who had been at Vetera
during the siege, all tough soldiers with a grievance against their
generals. Against his orders, more than the thousand started with him,
openly complaining on the march that they would not put up with famine
and the treachery of their generals any longer. On the other hand,
those who stayed behind grumbled that they were left to their fate now
that part of the garrison had been removed. Thus there was a double
mutiny, one party calling Vocula back, the others refusing to return
to camp.

Meanwhile Civilis laid siege to Vetera. Vocula retired to Gelduba, 36
and thence to Novaesium, shortly afterwards winning a cavalry skirmish
just outside Novaesium. The Roman soldiers, however, alike in success
and in failure, were as eager as ever to make an end of their
generals. Now that their numbers were swelled by the arrival of the
detachments from the Fifth and the Fifteenth[326] they demanded their
donative, having learnt that money had arrived from Vitellius. Without
further delay Flaccus gave it to them in Vespasian's name, and this
did more than anything else to promote mutiny. They indulged in wild
dissipation and met every night in drinking-parties, at which they
revived their old grudge against Hordeonius Flaccus. None of the
officers ventured to interfere with them--the darkness somehow
obscured their sense of duty--and at last they dragged Flaccus out of
bed and murdered him. They were preparing to do the same with Vocula,
but he narrowly escaped in the darkness, disguised as a slave.
When the excitement subsided, their fears returned, and they sent 37
letters round by centurions to all the Gallic communities, asking for
reinforcements and money for the soldiers' pay.

Without a leader a mob is always rash, timorous, and inactive. On the
approach of Civilis they hurriedly snatched up their arms, and then
immediately dropped them and took to flight. Misfortune now bred
disunion, and the army of the Upper Rhine[327] dissociated itself
from the rest. However, they set up the statues of Vitellius again in
the camp and in the neighbouring Belgic villages, although by now
Vitellius was dead.[328] Soon the soldiers of the First, Fourth, and
Twenty-second repented of their folly and rejoined Vocula. He made
them take a second oath of allegiance to Vespasian and led them off to
raise the siege of Mainz. The besieging army
