Snot-nosed, scrawny children wearing little more than rags swarmed in, clamouring for a coin or a crust, while their lank-haired, pregnant mothers gazed at them with eyes deadened by a life of misery. Half-dressed girls posed provocatively in some doorways, their rouged cheeks and lips unable to conceal the fact that they were barely out of childhood. Unshaven, ill-clad men lounged around, rolling sheep tail bones in the dirt for a few worn coins. They stared suspiciously, but none dared hinder the friends' progress. At night it might be a different matter, but already they were under the shadow of the great wall, with its smartly turned out sentries marching to and fro along the battlements. Although common, lawlessness was punished where possible by the authorities, and a shout of distress would bring help clattering down one of the many sets of stairs. It was a shame, thought Hanno with a backward glance at the pitiable specimens, that such men weren't expected to fight for their country, as ordinary Roman citizens were. Given a purpose, their lot would improve infinitely, as would that of Carthage.

The tang of salt grew strong in the air. Gulls keened overheard, and the shouts of sailors could be heard from the ports. Feeling his excitement grow, Hanno charged down a narrow alleyway, and up the stone steps at the end of it. Suniaton was right behind him. It was a steep climb, but they were both extremely fit, and reached the top without breaking sweat. A red concrete walkway extended the entire width of the wall – thirty paces – just as it did for the entire length of the defensive perimeter. Strongly built towers were positioned every fifty steps or so. The soldiers visible were garrisoned in the barracks which were built at regular intervals below the ramparts.

The nearest sentries, a quartet of Libyan spearmen, glanced idly at the pair, but seeing nothing of concern, looked away. In peacetime, citizens were allowed on the wall during the hours of daylight. Perfunctorily checking the turquoise sea below their section, the junior officer fell back to gossiping with his men. Hanno trotted past, admiring the Libyans' massive round shields, which were even larger than those used by the Greeks. Although made of wood, they were covered in goatskin, and rimmed with bronze. The same demonic face was painted on each, and denoted their unit. He didn't envy them their heavy bronze helmets and padded linen cuirasses, though. Despite the fact that they were doing nothing, the Libyans' sallow faces were covered with sweat. Hanno wasn't naive: he had trained with similar armour and weapons. In spite of his dreams, the idea of marching long distances and fighting under the hot sun was intimidating. He was glad that diversions like fishing were still an option.

Trumpets blared one after another from the naval port, and Suniaton jostled past, outstripping him. 'Quick,' he shouted. 'They might be launching a quinquereme!'

Hanno chased eagerly after his friend. The view from the walkway into the circular harbour was second to none. In a masterful feat of engineering, the Carthaginian warships were invisible from all other positions. Protected from unfriendly eyes on the seaward side by the city wall, they were concealed from the moored merchant vessels by the naval port's slender entrance, which was only just wider than a quinquereme, the largest type of warship.

Hanno scowled as they reached a good vantage point. Instead of the imposing sight of a warship sliding backwards into the water, he saw only a purple-cloaked admiral strutting along the jetty which led from the periphery of the circular docks to the central island, where the navy's headquarters were. Another fanfare of trumpets sounded, making sure that every man in the place knew who was arriving. 'What has he got to swagger about,' Hanno muttered angrily. Malchus reserved much of his anger for the incompetent Carthaginian fleet, so he had learned to feel the same way. Carthage's days as a superpower of the sea were long gone, smashed into so much driftwood by Rome during the two nations' bitter struggle over Sicily. Remarkably, the Romans had been a non-seafaring race before the conflict. Undeterred by this major disadvantage, they had learned the skills of naval warfare, adding a few tricks of their own in the process.

Since her defeat, Carthage had done little to reclaim the waves.

Hanno sighed.

Truly all their hopes lay on the land, with Hannibal. Some time later, Hanno had forgotten all his worries. Nearly a mile offshore, their little boat was positioned directly over a mass of tunny. The shoal's location had not been hard to determine, thanks to the roiling water created by the large silver fish as they hunted sardines. Fishing boats dotted the location and clouds of seabirds swooped and dived overhead, attracted by the prospect of food. Suniaton's source had been telling the truth, and neither youth had been able to stop grinning since their arrival. Their task was simple. While one rowed, the other lowered their small net into the sea. Although they had seen better days, the plaited strands were still capable of landing a good catch. Small pieces of wood along the top of the net helped it to float, while tiny lumps of lead pulled its lower edge down into the water. Their first throw had netted nearly two dozen tunny, each one longer than a man's forearm. Subsequent attempts were just as successful, and now the bottom of the boat was calf deep in fish. Any more, and they would risk overloading their craft.

'A good morning's work,' Suniaton declared.

'Morning?' challenged Hanno, squinting at the sun. 'We've been here less than an hour. It couldn't have been easier, eh?'

Suniaton regarded him solemnly. 'Don't put yourself down. Think of the money we'll make selling this lot. I think our efforts deserve a toast.' He reached into his pack and with a flourish, produced a small amphora.

Amused by his friend's irrepressible character, Hannibal laughed, which encouraged Suniaton to continue talking as if he were serving guests at an important banquet.

'Not the most expensive wine in Father's collection, I recall, but a palatable one nonetheless.' Using his knife, he prised off the wax seal. Raising the amphora to his lips, he gulped a large mouthful. 'Very tasty,' he declared, handing over the clay vessel.

'Philistine. Taste it slowly.' Hanno took a small sip and rolled it around his mouth as Malchus had taught him. The red wine had a light and fruity flavour, but possessed little undertone. 'It needs a few more years, I think.'

'Now who's being pompous?' Suniaton kicked a tunny at him. 'Shut up and drink!'

Grinning, Hanno obeyed, taking more this time.

'Don't finish it,' cried Suniaton.

Despite his protest, the amphora was quickly drained. At once the ravenous pair launched into the bread, nuts and fruit which Suniaton had bought. With their bellies full, and their work done, it was the most natural thing in the world to lie back and close their eyes. Unaccustomed to consuming much alcohol, they were both snoring before long. It was the cold wind on his face which woke Hanno. Why was the boat moving so much, he wondered vaguely. He shivered, feeling quite chilled. Opening gummy eyes, he took in a prone Suniaton opposite, still clutching the empty amphora. At his feet, the heaps of blank-eyed fish, their bodies already rigid. Looking up, Hanno felt a pang of fear. Instead of the usual clear blue sky, all he could see were towering banks of blue-black clouds pouring in from the northwest. He blinked, refusing to believe what he was seeing. How could the weather have changed so fast? Mockingly, the first spatters of rain hit Hanno's upturned cheeks a moment later. Scanning the choppy waters around them, he could see no sign of the fishing craft which had surrounded theirs earlier. Nor could he see the land. Real alarm seized him.
