 In the same year (76 BC) Sertorius was joined by Marcus Perpenna, who brought the remnant of the army of rebellious consul Marcus Aemilius Lepidus from Sardinia.However, Perperna had only reluctantly agreed to put himself under Sertorius's command; he had sailed his army to Liguria and was raising troops from among the Ligurians and Gauls there, when his men heard that Pompey was marching north to deal with them, they demanded that Perpenna take them to Hispania and join up with Sertorius.Perpenna brought a substantial force of fifty-three cohorts (almost five-and-a-half legions) with him to Spain.
