Passage: While Hannibal was marching through Gaul, Scipio had landed with his army at the allied Greek city of Massilia. He then sent a cavalry patrol north, up the eastern bank of the Rhone River, which clashed with a similar force of Numidian light cavalry and, after a hard fought skirmish, drove off the Carthaginians. Scipio marched north from his base, while Hannibal marched east towards the Alps. Arriving at the deserted Carthaginian camp, Scipio learned that Hannibal was three day's march away and decided to send his forces to Iberia under the command of his elder brother Gnaeus, who had been consul in 221 BC, while he himself returned to Northern Italy to organize the defences against Hannibal.

Question: Who commanded the fighting men in Massilia while Hannibal was in Gaul?
Scipio
