Hannibal at the Rhone River. You have changed History!  Bypassing Saguntum would be a major mistake, because the inhabitants truly despise you, and would do everything they could to disrupt your further progress.  You are already far from home, with stretched supply lines, and are surrounded by hostile natives.  You can ill afford to leave a fortified city, with an enemy port in it, standing to the rear of your advance.  You must make allies as you go, or at least, leave them them in fear of your retribution.  Reducing the city was your correct option.


In spite of the time and effort required, you made the right choice to capture Saguntum before moving on.  Ironically, Hannibal almost lost his life here, when a javelin, thrown down from the city wall, rammed through his leg.  He survived quite nicely, and the destruction of Saguntum was assured.  The Saguntines hated Hannibal so much that they burned and melted their precious objects so that he could not use them, and then threw themselves into the fire, rather than become his mercenaries or slaves.
    At home, this victory caused his popularity to grow also, as he was elected suffete (pronounced, according to Durant, as "show-feet", an indication of the Semitic origins of the Carthaginian language).  Suffete was similar to being consul in Rome, and gave Hannibal carte blanche to carry forth his war against Rome.  Though he was, of course, appropriately appreciative and humbled by the honor, he must have been pleased that his plans were proceeding so quickly.  This position virtually guaranteed that he would get the support he needed to bring his plans to fruition.  Here is his next choice.


The conflict with Rome was now in full swing.  Hannibal took his troops north, crossed the Pyrenees, and headed east.  He has what we will call the Replacement Factor.  He is in command of a mostly mercenary army, and cannot generally request more troops from home.  He usually solves this by bringing into his army disgruntled natives of Spain and Gaul who were dissatisfied with Roman rule.  By promising them self-control (following Roman defeat), and the spoils of war, Hannibal convinced many that he was the solution to their problems with Rome.  He showed his benevolence by causing as little disruption as he could in the lives of the tribes that allied with or remained neutral to him, and his ferocity by destroying those who opposed him.
    At the Rhone River, he found himself unable to cross, due to the presence of hostile Gauls on the other side.  Patiently, he had his men learn to build dugout canoes, and prepared for his first "naval" assault.  In the meantime, he sent part of his force upstream to find a better place to ford the river.  He also sent a cavalry detachment downstream to investigate rumors that the Romans had landed a force at the mouth of the Rhone.
    His encounter with the Gauls worked out perfectly.  At an agreed-upon time, Hannibal's men plunged into the river and began to cross.  The Gauls waited in excitement, expecting to cut the Carthaginians to shreds as they tried to leave their canoes.  With the canoes nearly across, Hannibal's upstream force, which had forded the river and circled behind the Gauls, began an attack that forced the Gauls to divide their forces.  Caught so unawares, the Gauls fell into confusion, found themselves now surrounded, and were destroyed.
    Downstream, Hannibal's cavalry detachment found itself in proximity to a Roman cavalry detachment.  Despite their orders to the contrary, both groups decided to attack, and a battle ensued.  Though there was no clear winner, both sides now knew where their enemy was.  After the battle, the remainders of both detachments returned to their camp to report, leading to your next decision.
    Hannibal now knows that the Romans are at the mouth of the Rhone, in great numbers.  His original plan was to continue on to cross the Alps, and descend upon Rome from the north.  Now, however, he has crossed the Pyrenees, and his men have had a taste of high altitudes and bitterly cold temperatures.  The Alps are much higher and more treacherous, and will provide a much more formidable obstacle.
    To travel south and engage the Romans now may mean that Hannibal could destroy their army in one major battle, and therefore leave Rome crippled for the rest of his assault.  He would have to be able to capture their navy, in order to have the ships he would need to land in Italy.  Even if he were successful in this, he would face what we will call the Port Problem.  The geography of Italy is such that there are very few good harbors in which he could land, and these might be fortified against him.
    What choice would you make?
Cross the Alps.
Go down the Rhone.
