 To secure their rear, they consolidated their network of alliances with the Numidians.To keep the Romans in check, soldiers and supplies were sent to Hannibal in Bruttium and Mago, and an embassy to Philip V of Macedon with the mission to negotiate a Macedonian invasion of either Italy or Sicily.All these measures had little effect, because Philip had just concluded the peace of Phoenice with P. Sempronius Tuditanus, a Roman general, thereby bringing the First Macedonian war to an end, and the Carthaginian alliance with the most powerful Numidian king Syphax did not stop Scipio from sailing to Africa in 204 BC.
