The conquest of Carthage and the North African provinces was just the beginning for Justinian's ambition. He must have Rome. But like Carthage, he must find a reason to attack the Ostrogoths who now hold it. And like Carthage, this reason is given to him when the Ostrogothic Queen Amalsuntha, his ally, is murdered. But unlike Carthage, Belisarius now has only 7500 men, barely half of what he had for North Africa. He sails out anyway, making his first stop at the island of Sicily. All the cities except Panormus surrender to him, and Panormus he takes quickly by seizing their harbor with his ships. Meanwhile, Justinian has bribed the Franks to invade Italy from the north while another his generals marches from the east. But just when the Ostrogothic king is on the verge of surrender, disaster strikes. The other Byzantine general dies, and Belisarius is forced to return to Carthage to quell a revolt. The conquest loses its momentum and the Ostrogothic king imprisons the Roman ambassador. Justinian will not be stopped, and orders Belisarius to return to Italy once North Africa is secure. Alone, Belisarius marches up the coast of Italy until he meets resistance at Neapolis. With his forces too thinned to mount a siege, he engineers a sneak attack by invading through the pipe of a dried, broken aqueduct. Neapolis falls and the way now lies open to Rome.
