As Hannibal's chances of winning the Second Punic War began to fade, and the conflict turned in Rome's favour, the network of alliances and vassals that Carthage had forged and stolen from Rome began to unravel. The Romans found themselves able to renegotiate many treaties, and forge new ones also. Macedon, with whom Carthage had entreated aid in the war, signed the Treaty of Phoenice with Rome in 205BC, after it became obvious the conflict had reached a stalemate. This deprived Hannibal of the fresh Greek reinforcements he sought which, along with the loss of his brother Hasdrubal's army and the defection of Numidian tribes, signalled an irreversible change in Carthaginian fortunes.
