Scipio Goes to Andalusia - Hasdrubal Crosses the Pyrenees
Scipio employed the winter of 545-6 in breaking up his fleet and increasing his land army with the men thus acquired, so that he might at once guard the north and assume the offensive in the south more energetically than before; and he marched in 546 to Andalusia. There he: encountered Hasdrubal Barcas, who, in the execution of his long-cherished plan, was moving northward to the help of his brother.
A battle took place at Baecula, in which the Romans claimed the victory and professed to have made 10,000 captives; but Hasdrubal substantially attained his end, although at the sacrifice of a portion of his army. With his chest, his elephants, and the best portion of his troops, he fought his way to the north coast of Spain; marching along the shore, he reached the western passes of the Pyrenees which appear to have been unoccupied, and before the bad season began he was in Gaul, where he took up quarters for the winter.
