 Having arrived with reinforcements, he negotiated the surrender of Ocilis and defeated the Nergobriges, before they and the other Celtiberian tribes of the Arevaci, the Belli, and the Titthi, sued for peace with Rome.Marcellus sent ambassadors back to the Senate in Rome, urging them to accept the peace proposals and end the long war in Spain.The Senate however, refused and began gathering a new army to be again sent to Spain the following year, appointing Lucius Licinius Lucullus, Consul-Elect for 151 BC, to replace Marcellus once his term as Consul expired.
