[3] During the later stages of the Gallic War he commanded two legions on the southern slope of the heights during the siege of Alesia, where Caesar's defences were weakest.
[4] With great difficulty, and the timely support of Titus Labienus, he withstood the last major attack on the Roman position there on 2 October 52 BC.
[7] Two years after Alesia, the Andecavi, led by Dumnacus, continued war against Rome and laid siege to Limonum (present-day Poitiers), an oppidum of the Pictones.
[8] On the outbreak of the civil war in 49 BC, Rebilus accompanied Caesar in his march into Italy and he was sent to Brundisium as an unsuccessful negotiator to Pompey.
[10] He pushed Curio to take advantage of a break in the enemy lines to achieve victory at the Battle of Utica,[11] and after the latter's defeat and death, he was one of the few who escaped from Africa.
