reign, further imperial laxness appears to have encouraged habitual
raiding over the upper Rhine.57 Large-scale renewal of Roman
aggression threatened in the late 30s. Tiberius died in 37 and was
succeeded by Gaius, who showed an interest in Germania. The details
of Gaius’ notorious Germanic ‘campaign’ of 40 are very diYcult to
establish from our hostile sources, Suetonius and Dio. Contrary to
what they claim, the emperor must have journeyed to the Rhine on
more than a whim.58 Gaius needed military success, and it would
have suited him to distance himself from political troubles in Rome.
As a descendant of Julius Caesar, the grandson of Drusus I and the
son of Germanicus, it was Wtting for him to carry Roman arms over
the Rhine on a grand scale.59 That, in the event, there was little more
than small-scale Wghting, may have resulted from panic caused by the
supposed conspiracy of Cn. Cornelius Lentulus Gaeticulus in Upper
Germany. This cut across Gaius’ preparations, prompting him to
leave Italy in haste and making him nervous of unpredictable long-
distance undertakings.60 The western Germani continued to be left
for the most part in peace.
More border control characterized the reigns of Gaius’ successors,
Claudius (41–54) and Nero (54–68). (The former conWned his cam-
paigning to Britain; the latter, to his cost, took no interest in military
aVairs.) In 41, Gabinius Secundus, commander of Lower Germany,
fought against Chauci, was victorious, but perhaps exaggerated the
signiWcance of his achievements. In the same year, Sulpicius Galba,
the future emperor, then commanding Upper Germany, overcame
Chatti.61 In 47, the Cherusci asked for a king since—a further sign of
disruptive Roman inXuence on Germanic society—civil war had
destroyed their nobility. Claudius returned to them the sole surviving
member of their royal house, Arminius’ nephew, then resident in
Rome.62 In 48, temporary Roman administrative weakness allowed
Chauci to practise piracy along the coasts of Gaul. This was ended by
