 The people of Segeda, whose wall had not been completed, fled and sought refuge among the Arevaci of Numantia (7 km north of Soria), who welcomed them.The Arevaci initially tried to mediate, but Nobilitor would only accept complete surrender ("deditio").Consequently, the Celtiberians raised an army of 20,000 infantry and 500 cavalry, and chose a Segedan, Carus, as its commander.
