Hannibal on the Ebro
At length, certainly, the greater part of the army and of the fleet was got ready for the expedition to Africa, and the second consul Publius Cornelius Scipio was ordered to the Ebro; but he took time, and when an insurrection broke out on the Po, he allowed the army that was ready for embarkation to be employed there, and formed new legions for the Spanish expedition.
So although Hannibal encountered on the Ebro very vehement resistance, it proceeded only from the natives; and, as under existing circumstances time was still more precious to him than the blood of his men, he surmounted the opposition after some months with the loss of a fourth part of his army, and reached the line of the Pyrenees.
That the Spanish allies of Rome would be sacrificed a second time by that delay might have been as certainly foreseen, as the delay itself might have been easily avoided; but probably even the expedition to Italy itself, which in the spring of 536 must not have been anticipated in Rome, would have been averted by the timely appearance of the Romans in Spain.
Hannibal had by no means the intention of sacrificing his Spanish "kingdom," and throwing himself like a desperado on Italy. The time which he had spent in the siege of Saguntum and in the reduction of Catalonia, and the considerable corps which he left behind for the occupation of the newly-won territory between the Ebro and the Pyrenees, sufficiently show that, had a Roman army disputed the possession of Spain with him, he would not have been content to withdraw from it; and--which was the main point--had the Romans been able to delay his departure from Spain for but a few weeks, winter would have closed the passes of the Alps before Hannibal reached them, and the African expedition would have departed without hindrance for its destination.
