The two consuls also opposed a proposal by the tribunes to purchase grain from abroad because the price of grain was going up. Scipio Nasica made a speech which quieted the restless plebs.

, their main city. He convinced Brutus, who was the commander of Hispania Ulterior and his brother-in-law, to join him. Messengers from the senate arrived and asked why Aemilius sought a new war. They warned him not to continue the attacks on the Vaccaei. Aemilius sent them back to Rome and wrote that it would be dangerous to abandon the war. The siege lasted a long time, during which the Romans run short of food and many men and all the animals died. Aemilius and Brutus eventually had to withdraw, doing so in a very disorderly manner. The Pallantines harassed their flanks and rear and killed many men. When Rome heard of this, Aemilius was recalled, stripped of his command and consulship, and fined. Brutus does not seem to have been punished.


Family

Callaicus was married to a Clodia (who had previously been married to Publius Licinius Crassus Dives Mucianus and had three children with him) and with her had at least two children, a son named Decimus Junius Brutus and a daughter named Junia who became the mother of Gaius Claudius Marcellus.
