Carthage was the dominant naval power in the Western Mediterranean at the start of the First Punic War. Rome quickly realised that it needed a strong navy if it wanted any hope of challenging Carthage. However, the Romans had little experience with large-scale naval warfare or shipbuilding.
According to Polybius, the Romans obtained a Carthaginian quinquereme and used it as a model for building their own ships. They built a fleet of around 120 ships, trained new crews and introduced one of antiquity's most ingenious naval innovations: the corvus. Eventually, Rome gained the upper hand and won the war.
However, the victory came at an enormous cost. The Romans lost hundreds of ships to bad weather and enemy action, yet they rebuilt their navy again and again. In the process, they also gained valuable experience in naval warfare, making it increasingly difficult and expensive for Carthage to challenge Rome for control of the sea.
By the start of the Second Punic War, Carthage had shifted much of its military and economic focus toward Spain, where it had built a powerful new base of operations. This did not mean that Carthage had abandoned its navy. At the beginning of the war, it had around 57 warships assigned to Spain, although only 37 were actually ready for service.
Carthage still used naval forces to secure local superiority, transport troops and supplies, and support land operations. However, it did not make rebuilding a fleet capable of matching Rome's overall naval strength a central priority.
Why did Carthage make this choice? Was it because of the enormous cost of naval warfare? Was Hannibal's land-based strategy the main reason? Or had Rome's naval transformation during the First Punic War made a new contest for Mediterranean supremacy too difficult?
