149 BC The Roman army moved to Carthage and twice attempted to scale the city walls, from the sea and the landward sides, being repulsed both times, before settling down for a siege. Hasdrubal moved up his army and harassed the Roman supply lines and foraging parties. The Romans built two very large
battering rams and partially broke down a section of the wall. They
stormed the breach but fell into disorder while clambering through and were thrown back by the waiting Carthaginians. The Romans would have been in difficulty except for the actions of Scipio Aemilianus, who was serving with the 4th Legion as a
tribunea middle-ranking military position. Rather than join the attack as ordered, Scipio held back and spaced his men along the partially demolished wall, and so was able to beat off the pursuing Carthaginians when the Romans in front of him fled back through the
ranks of his unit. Censorinus's camp was badly situated and by early summer was so pestiferous that it was moved to a healthier location. This, however, was not as defensible, and the Carthaginians inflicted losses on the Roman fleet with
fire ships. Separately, a night attack was launched against Manilius's camp; a dangerous outcome for the Romans was again averted by Scipio's prompt action. The Romans made repetitions of these attacks more difficult by building additional field fortifications.
148 BC The Romans elected two new consuls in 148 BC, but only one of them was sent to Africa:
Calpurnius Piso;
Lucius Mancinus commanded the navy as his subordinate. He pulled back the close siege of Carthage to a looser
blockade and attempted to mop up the other Carthaginian-supporting cities in the area but failed. Meanwhile, Hasdrubal, commander of the Carthaginian field army, overthrew the civilian leadership of Carthage and took command himself. A Numidian chief came over to the Carthaginians with 800 cavalry. Carthage allied with
Andriscus, a pretender to the
Macedonian throne, who invaded Roman Macedonia, defeated a Roman army, had himself crowned King Philip VI, and sparked the
Fourth Macedonian War.
147 BC Scipio intended to stand in the 147 BC elections for the post of ; this was a natural progression for him and at age 36 or 37 he was too young to stand as consul, for which the minimum age requirement was 42. But the public demand to appoint him as consul, and so allow him to take charge of the African war, was so strong that the Senate put aside the age requirements for all posts for the year. There was considerable political manoeuvring behind the scenes, much of which is opaque in the sources, and it is not known to what extent, if any, Scipio helped orchestrate this outcome. In any event, he secured sole command in Africa, the usual right to conscript enough men to make up the numbers of the forces there, and the unusual entitlement to enroll volunteers. Meanwhile, early in 147 BC Mancinius seized an unexpected opportunity to capture a
sally port and forced 3,500 men into the city, 3,000 of whom were lightly armed and armoured sailors. Mancinius sent messages asking for reinforcements. Sources have Scipio arriving at Utica that evening to take up his post. He sailed overnight for Carthage and arrived just in time to evacuate Mancinius's hard-pressed force as it was expelled by a Carthaginian counterattack. Scipio moved the Roman main camp back to near Carthage, closely observed by a Carthaginian detachment of 8,000. He made a speech demanding tighter discipline and dismissed those soldiers he considered ill-disciplined or poorly motivated. He then led a night march with a strong force that culminated in an assault against what the Romans considered to be a weak point in Carthage's main wall. A gate was seized and 4,000 Romans pushed into the city. Panicked in the dark, the Carthaginian defenders, after an initial fierce resistance, fled. However, Scipio decided that his position would be indefensible once the Carthaginians reorganised themselves in daylight, and so withdrew. Hasdrubal, horrified at the way the Carthaginian defences had collapsed, had Roman prisoners tortured to death on the walls, in view of the Roman army. He was reinforcing the will to resist in the Carthaginian citizens; from this point there could be no possibility of negotiation or even surrender. Some members of the city council denounced his actions and Hasdrubal had them too put to death and took full control of the city. The renewed close siege cut off landward entry to the city, but a tight seaward interdiction was all but impossible with the naval technology of the time. Frustrated at the amount of food being shipped into the city, Scipio started to build an immense
mole to cut off access to the harbour. As work on this progressed, the Carthaginians responded by cutting a new channel from their harbour to the sea. They had built a new fleet of 50
triremesmedium-sized, manoeuvrable, oared warshipsand a large number of smaller ships since sacrificing their original fleet two years before. Once the channel was complete this sailed out, taking the Romans by surprise. A few days were necessary to trim the new-built ships and to train the new crews who had not been to sea for over two years and were out of the habit of operating together, and by the time the Carthaginians felt ready to give battle the Romans had concentrated their own naval forces. In
the engagement which followed, the Carthaginians held their own, with their lighter craft proving difficult for the Roman ships to deal with. Breaking off the engagement, the Carthaginian triremes were covering the withdrawal of their lighter vessels when a collision blocked the new channel. With the Carthaginian ships pinned against the city's sea wall with no room to manoeuvre, the Romans sank or captured many of them before the blockage was cleared and the Carthaginian survivors were able to escape back into harbour. The Romans now attempted to advance against the Carthaginian defences in the harbour area. Carthaginians swam across the harbour at night and set fire to several siege engines and many legionaries panicked and fled. Scipio intercepted them in the dark; when they disregarded his orders to halt he had his mounted bodyguard attack them. Nevertheless, the Romans eventually gained control of the quay and constructed a brick wall as high as the city wall. This took months to complete, but once in place it enabled 4,000 Romans to shoot onto the Carthaginian ramparts from short range.
146 BC Scipio's position as the Roman commander in Africa was extended for a year in 146 BC, and in the spring he launched the final assault. It came from the harbour area and Hasdrubal, expecting it, set fire to the nearby warehouses. Despite this, a Roman advance party broke through to the military harbour and captured it. The main assault force reached the city's main square, where the legions camped overnight. The next morning Scipio led 4,000 men to link up with the group at the military harbour; this group was delayed when they diverted to strip the gold from the Temple of Apollo. Scipio and his officers were helpless to prevent them and furious. The Carthaginians did not take advantage, having withdrawn to defensive positions. Having regrouped, the Romans systematically worked their way through the residential part of the city, killing everyone they encountered and firing the buildings behind them. At times, the Romans progressed from rooftop to rooftop, to prevent missiles being hurled down on them. It took six more days to clear the city of resistance, and on the last day Scipio agreed to accept prisoners. The last holdouts, including 900 Roman
deserters in Carthaginian service, fought on from the Temple of Eshmoun and burnt it down around themselves when all hope was gone. At this point, Hasdrubal surrendered to Scipio on the promise of his life and freedom. Hasdrubal's wife, watching from a rampart, then blessed Scipio, cursed her husband, and walked into the temple with her children, to burn to death. There were 50,000 Carthaginian prisoners, a small proportion of the pre-war population, who were sold into slavery. After the final week of fighting, Scipio gave the city over to the soldiers to plunder. After this, a commission of ten senators arrived, ordering Scipio to destroy whatever remained of Carthage and decreed nobody was allowed to settle there or rebuild; however, it was not forbidden to go upon the ground nor was the land
cursed, the notion that Roman forces then
sowed the city with salt is a 19th-century invention. Many of the religious items and cult-statues which Carthage had pillaged from Sicilian cities and temples over the centuries were returned with great ceremony. ==Aftermath==
