Despite being defeated on African soil, the Romans with their newfound naval abilities, roundly beat the Carthaginians in naval battle again – largely through the tactical innovations of the Roman fleet – at the Battle of the Aegates Islands. Carthage was left without a fleet or sufficient coin to raise a new one. For a maritime power, the loss of their access to the Mediterranean stung financially and psychologically, and the Carthaginians again sued for peace, during which negotiations, Rome battled the "Ligures" tribe in the Ligurian War and the "Insubres" in the Gallic War.
