The Rhone River is located in France and must be crossed to reach the Alps. Hannibal's plan of persuading the Roman allies to join him required him to take the Second Punic War to Italy
The feat alone of transporting an entire army of men and elephants to Italy is evidence of Hannibal's military aptitude.
Awaiting the Carthaginian army on the left bank of the Rhône was a tribe of Gauls called the Cavares.
Hannibal needed to reach the Alps quickly in order to beat the onset of winter. He knew that if he waited until springtime on the far side of the mountains, the Romans would have time to raise another army.
The army rested here for two days. It was the end of October and snowy weather, the length of the campaign, ferocity of the fighting, and the loss of animals sapped morale in the army's ranks
After the two days of rest, Hannibal ordered the descent from the Alps to begin.
