Histories 2.106

1The writers of those times who, while the Flavian house held power, composed records of this war, have reported concern for peace and love of the state as the motives, corrupting the causes into flattery: to us it seems that, besides their inborn fickleness and a loyalty that had become cheap once Galba was betrayed, rivalry and jealousy too, lest they be outstripped by others in Vitellius' favour, led them to ruin Vitellius himself. 1Caecina, having overtaken the legions, was by various arts undermining the minds of the centurions and soldiers, who were stubbornly loyal to Vitellius: Bassus, working at the same thing, had less difficulty, since the fleet was quick to change its loyalty because of the memory of its recent service for Otho.
