Some smaller cantons gave in their submission; but the Sugambri,
against whom the expedition was primarily directed, withdrew,
on the approach of the Roman army, with those under their protection
into the interior. In like manner the powerful Suebian canton
which oppressed the Ubii--presumably the same which subsequently
appears under the name of the Chatti--caused the districts immediately
adjoining the Ubian territory to be evacuated and the non-combatant
portion of the people to be placed in safety, while all the men
capable of arms were directed to assemble at the centre of the canton.
The Roman general had neither occasion nor desire to accept
this challenge; his object--partly to reconnoitre, partly to produce
an impressive effect if possible upon the Germans, or at least
on the Celts and his countrymen at home, by an expedition
over the Rhine--was substantially attained; after remaining
eighteen days on the right bank of the Rhine he again arrived
in Gaul and broke down the Rhine bridge behind him (699).
