Upon this, deserting their commander and their camp, they dispersed themselves through the several towns, each wishing to take care of his own effects.

[4] At this time, Clastidium was burned, and the legions were led thence against the Ilvatian Ligurians, who alone refused to submit. [5] That state, also, on learning that the Insubrians had been defeated in battle, and the Boians so terrified that they had not dared to try the fortune of an engagement, made a submis- [p. 1431]sion.
