 Upon learning of this, Marcellus nevertheless remained resolved to make peace in Spain and end the war before Lucullus' arrival.However, the Arevaci then attacked Nergobriga, the city of the Nergobriges, and broke the truce agreed with Marcellus.In retaliation, the Romans marched to besiege the Arevaci capital of Numantia; however, before the assault could begin, the Numantines re-opened negotiations for peace and, in a conference with Marcellus, the Numantine leader, Litenno, offered to make peace with Rome on behalf of the Arevaci, Belli and Titthi.
