Final answer:
During the first Punic War, Carthage had the advantage of a strong navy, but the Romans developed a tactic called the 'corvus' which allowed them to turn a sea battle into a land battle and neutralize Carthage's advantage.
Step-by-step explanation:
During the first Punic War, Carthage had an advantage over Rome in terms of their navy. Carthage had the largest fleet at the time, which gave them control of the seas. However, the Romans found a way to deal with this disadvantage by developing a tactic known as the 'corvus' (hook). This device was a boarding ramp with a sharp metal spike that could be dropped onto an enemy ship, allowing the Romans to board and fight the enemy on their own ship, turning a sea battle into a land battle where the Romans excelled. With this tactic, the Romans were able to neutralize Carthage's naval advantage and achieve victory.
