besieging the town, which sent a herald to ask for peace again. Marcellus said that he would not grant peace unless the Arevaci, Belli, and Titti asked for it together. The Nertobriges sent ambassadors to these tribes and asked Marcellus for leniency and for the renewal of the treaty made with Tiberius Gracchus. This was opposed by some rural people who had been incited to war. Marcellus sent envoys from each party to Rome to carry on their dispute there and sent private letters to the senate letters urging peace. For details about these deputations in Rome see the main article. Marcellus wanted to bring the war to an end himself and gain glory this way. The Senate rejected the peace and sent a new consul, Lucius Licinius Lucullus, to continue the war. Marcellus told the Celtiberians about the impending war and gave them back their hostages on their request. He held a conference with the Celtiberians. After this 5,000 Arevaci took Nergobriga.

He crossed the River Tagus and encamped near the town of Cauca (Coca in the province of Segovia).

This was agreed and Lucullus ordered 2,000 picked soldiers to seize the city. Then the rest of the Roman army, which had been ordered to kill all adult males, was let in. Only a few out of 20,000 managed to escape. Some of them
