But just when all preparation nears completion, you learn of a Gallic tribe - the Cavares - who occupy the far side of the Rhone's bank to prevent your crossing. Do you:

• Send a surprise attack. Send your trusted lieutenant Hanno with a detachment upstream, while you prepare the main camp to ferry the river and hold the attention of the Cavares. This way Hanno will clear the banks for your arrival.
• Cross Anyway. Load up your forces onto rafts and canoes, ferry the river, and crush them upon your landing.
• Surprise + Cross. Combine the two strategies. Send Hanno with his detachment with orders to strike on the third day while preparing the crossing of your main forces.
