Hasdrubal Gisco
The Scipio brothers launched a major offensive in 211 BC. The Carthaginian armies were separated, Hasdrubal Gisco being near Gades (modern Cádiz) with 10,000 troops, Mago near Castulo with another 10,000, and Hasdrubal with 15,000 soldiers near Amtorgis. The Scipios planned to confront the Carthaginians simultaneously and comprehensively destroy their armies.
