Driven out, Pyrrhus' Sicilian campaign ended in failure. Despite initial victories against the Carthaginians, Pyrrhus faced mounting resistance and dwindling support. The Carthaginians, with their superior naval power, blockaded Pyrrhus' supplies and reinforcements. Facing a protracted and costly war, Pyrrhus was forced to withdraw from Sicily in 278 BC, leaving the island under Carthaginian control.
