in 40 bc. From this date to 16 bc we see the Wrst round of
active imperial policing on the Rhine, involving Agrippa (38 bc),
C. Carrinas and Nonius Gallus (30–29 bc), M. Vinicius (25 bc), and
Agrippa again (21 bc). These took action against Germanic raiding,
the hiring of Germanic mercenaries by communities west of the
Rhine, Germanic action against Roman traders, and generally
showed the imperial Xag.19 In 16 bc, however, we have apparent
conWrmation of the continuing existence of the Germanic threat.
Sugambri, Usipetes and Tencteri cruciWed a number of Romans in
their own territories, then crossed the Rhine and plundered eastern
Gaul. They fell on the army of M. Lollius, commander-in-chief in the
region, and captured the standard of the Fifth legion. The incident
forced Augustus to travel to Gaul, where he remained for three
years.20 It is not surprising that this ‘Lollian disaster’ (Lolliana
clades)21 has been seen as the immediate stimulus for the subsequent
concentration of Roman forces on the Rhine and, from 12 bc, a great
push into Free Germany.22 This is unconv incing. Dio tells us that, in
16 bc, agreement was soon reached with the Germani; and Suetonius
comments that what happened to Lollius was more shameful than
damaging.23 We are again in the presence of high-level raiding, not
invasion. Probably, as was to happen in the mid-fourth century,24
Roman complacency led to events getting out of hand, with relatively
minor casualties (Lollius himself survived) but great Roman embar-
rassment.25 More likely is that, having arrived in Gaul, Augustus
took stock of the situation in the west and only then determined
on expansion into Germania. The time was ripe. Spain and Gaul
were now for the most part subdued. On the upper Rhine and
upper Danube all that remained was the subjugation of the Alpine
areas, achieved by the campaigns of Drusus and Tiberius, Augustus’
stepsons, in 16–15 bc.26 The transportation infrastructure that en-
