In the spring of 208BC, Hasdrubal moved to engage Scipio at the Battle of Baecula. The Carthaginians were defeated, but Hasdrubal was able to withdraw the majority of his army in good order. Most of his losses were among his Iberian allies. Scipio was not able to prevent Hasdrubal from leading his depleted army over the western passes of the Pyrenees into Gaul. In 207BC, after recruiting heavily in Gaul, Hasdrubal crossed the Alps into Italy in an attempt to join his brother, Hannibal.
