Quintus Fulvius Nobilior
Quintus Fulvius Nobilior was in charge of a major military campaign in Spain, which was largely unsuccessful. The Roman army was initially deployed against the oppidum of Segeda, whose Celtiberian inhabitants, the Belli, had been strengthening the walls. Segeda was destroyed, but the Belli assembled an army which ambushed the Roman army inflicting heavy losses. Moving west to the meseta, Nobilior laid siege to Numantia, an oppidum whose inhabitants were to give Rome trouble for years. The Roman army faced difficult conditions in the winter and had to withdraw. Nobilior was replaced as consul in 152 BC by Marcus Claudius Marcellus.
