In this wide market-place, this bare spot of open ground which to-day lies cumbered with iron bedsteads, and piled with empty cases, the débris of last market day, the bitterest tragedy of Naples was played out, and a scene enacted of which the infamy rang through all the world. There is no spot in the whole city less beautiful or more interesting than the Mercato; and in the hot afternoon, while the churches are closed, and half the city sits drowsy in the shady spots, I know no better way of passing time than in recalling some of the poignant memories which haunt this place of blood and tears.

In an earlier chapter of this book, when I gave a rapid sketch of the succession of Hohenstaufen, Anjou, and Aragon to the throne of the Two Sicilies, I passed on without pausing on the story of the boy-king Corradino, little Conrad, as the Italians have always called him. It is time now to tell the tale, for it was on this spot that the lad was murdered.

I need not go back on what I have already said so far as to repeat how Charles of Anjou defeated Manfred and slew him outside the walls of Benevento, nor how utterly the party of the Ghibellines, the Emperor's men, were cast down throughout Italy by that great triumph of the Guelf. When Manfred fell and his wife, Queen Helena, passed with her children into lifelong captivity, the House of Hohenstaufen was not extinct. There remained in Germany the true heir of Naples, a king with a better title than Manfred had possessed, Corradino, a boy of five, who grew up in the keeping of his mother, Elizabeth of Bavaria; and as year after year went by found his pride and fancy stimulated by many a tale of the rich heritage beyond the mountains which was his by every right, but was reft from him by an usurper, and lay groaning under the rule of an alien and an oppressor. Tales such as these must have had for the child all the fascination of a fairy story; but as his years increased, and he came to the comprehension of what wrong and injury meant, they touched him far more nearly, and all the courage of his high race, all the spirit which he derived from the blood of emperors and kings, urged him on to strike one stout blow at least for the recovery of that land which was his father's, that sunny kingdom where the blue sea kissed the very feet of the orange groves, and marble palaces gleamed out of the shade of gardens such as the boy had never seen except in dreams.

His mother did her best to scatter these dreams, and bring him back to the plain prose of life. Italy, she said, had always sucked the blood and strength of the Hohenstaufen, and if she could, she would stop the drain ere it robbed her of her only child. But the task was too great for her. Not from Naples only, which was really full of nobles ready to revolt against the tyrant of Anjou and return to their old allegiance, but from a dozen other cities in northern Italy, where the Ghibellines waited for the coming of a leader, the growth of Conradin to manhood was watched impatiently; and when he was turned fifteen, strong, handsome, and kingly in every act, the hopes of his partisans could be restrained no longer. Pisa sent her embassies to bid him hasten. Verona, ancient home of the Ghibellines, assured him of support. Siena, Pavia, implored him to come and free his people. The task they said was easy, and the glory great. More than that, it was a righteous duty to resume what was his own. Many a burning tale of wrong committed by the French was poured into the lad's ears; and the end was that little Conrad broke away from his mother's prayers and tears, and crossed the Alps in the autumn of the year 1267 at the head of 10,000 men, being then fifteen, and by the universal consent of all who saw him both handsome in his person and by his breeding worthy to be the son of many kings.

At first all went well with him. At Verona he was received with the honours of a conqueror. The mere news that his standard had been seen coming down from the high Alpine valleys drew the exiles of Ferrara, Bergamo, Brescia, and many another city in crowds to welcome him. Padua and Vicenza sent him greeting; and in January he moved on to Pisa, where the same joy awaited him. The Pisan fleet was of high power in those days, and it was sent at once to ravage the coasts of Apulia and Sicily, where it inflicted a sound drubbing on the French. Near Florence, too, Conradin's army gained a victory, and when he moved on to Rome, where Henry of Castile, who ruled the city in the absence of the Pope, had joined his party, the hopes of every Ghibelline in Italy were high and proud, while Charles of Anjou was seriously anxious for his throne.

It was on the 18th of August of the year 1268 that Conradin left Rome. Charles expected him by the ordinary route of travellers which lies through Ceperano, San Germano, and Capua. That route was studded with fortresses and was easy to defend—for which sufficient reason Conradin did not take it. His aim was not to make for Naples by the shortest way, but rather to get through the mountains, if he could without a battle, and to raise Apulia, where he was certain of support, not only from the Saracens of Lucera, but from many other quarters also. So he struck off from Tivoli towards the high valleys of the Abruzzi, through which he found a way not only unguarded, but cool, well watered and fresh, considerations of vast moment to the leader of an army through southern Italy in August. It was the line of the ancient Roman road, the "Via Valeria," and he followed it until on the 22nd of August as his troops came down from the hills of Alba, debouching on the plain of Tagliacozzo, some five miles in front, they saw the lances of Anjou gleaming on the heights of Antrosciano, drawn up in a position which was too strong for attack.

Conradin's army lay across the road to Tagliacozzo, offering battle to the king, who looked down upon the host of the invaders, and liked not what he saw. He had pressed on from Aquila, and was uneasy about the loyalty of that stronghold in his rear. Night fell; but before dusk hid the long line of foes upon the plain, Charles had seen an embassy ride into their ranks, and men said it came from Aquila, offering the town to Conradin. This was what Charles chiefly feared. He would trust no man but himself to learn the truth; and spurring his horse across plain and mountain through the night, he rode back headlong till he drew rein beneath the walls of Aquila, and shouted to the warder on the walls, "For what king are you?" Sharp and quick the answer came, "For King Charles"; and the King, reassured, rode back wearily towards his camp sleeping round the fires on the mountains.

He slept long that night, notwithstanding the hazard which lay upon the cast of battle; and when at length he woke, the host of the invaders was already marshalled along the bank of the River Salto, which formed their front. Charles scanned their line, and his heart sank, so great was their multitude. In something like despair he turned for counsel to a famous warrior who had but just landed from Palestine, where he had won world-wide renown, Alard de St. Valery. The wary Frenchman did not question that the chances of the coming fight were against Anjou. "If you conquer," he said, "it must be by cunning rather than by strength." Charles allowed him to make those dispositions which he pleased; and thereupon St. Valery placed a strong force of lances, with the King himself at their head, in a hollow of the hills, where they could not be seen. Then he hurled against Conradin two successive attacks, both of which were repulsed with heavy loss. Charles wept with rage to see his knights so broken, and strove to break out to rescue them, but St. Valery held him back, and Conradin, seeing no more enemies, thought the battle won. His men unhelmed themselves. Some went to bathe in the cool river. Others, after the fashion of the day, plundered the fallen knights. One large body under Henry of Castile had pursued the fleeing French far over plain and mountain. All this St. Valery lay watching in dead silence from his hiding in the hollow of the hills.

At last the moment came, and the serried ranks of the fresh warriors rode down upon their unarmed and unsuspecting enemies. No time was given to arm or form up the troops. Some perished in the water. Others died struggling bravely against the shock of that horrible surprise. The trap was perfect. All either died or fled; and in one brief hour Conradin, who had thought himself the conqueror of his father's throne, was fleeing for his life across the hills, a fugitive devoid of hope. Never, surely, was there so sudden or terrible a change of fortune.

With Conradin fled Frederick of Baden, his close friend, not long before his playmate; and these two princely lads were accompanied by a few faithful followers, the last remnant of what so short a time before was a noble army. All that night they sped across the mountains in the direction of the coast, where they hoped to find some craft which would carry them to Pisa, a safe haven for them all. They struck the sea near Astura in the Pontine marshes. On the shore they found a little fishing boat; and having sought out the men who owned it, they offered large reward for the voyage up the coast. The fellows demurred that they must have provisions for the trip; and Conradin, taking a ring from his finger, gave it to one of them and told him to buy bread at the nearest place he could. It was a fatal imprudence. The sailor pledged the ring at a tavern in exchange for bread. The host saw the value of the jewel, and took it instantly to the lord of the castle near at hand.
