At last, in the spring of the year 429, the Vandals and the Alani, having joined forces on the Spanish coast under their King, Genseric, crossed the Straits of Gibraltar. It was devastation on a large scale this time. An army of eighty thousand men set themselves methodically to plunder the African provinces. Cherchell, which had already been sorely tried during the revolt of Firmus the Moor, was captured again and burned. All the towns and fortified places on the coast fell, one after another. Constantine alone, from the height of its rock, kept the invaders at bay. To starve out those who fled from towns and farms and took refuge in the fastnesses of the Atlas, the Barbarians destroyed the harvest, burned the grain-houses, and cut down the vines and fruit trees. And they set fire to the forests which covered the slopes of the mountains, to force the refugees out of their hiding-places.

This stupid ravaging was against the interest of the Vandals themselves, because they were injuring the natural riches of Africa, the report of which had brought them there. Africa was for them the land of plenty, where people could drink more wine than they wanted and eat wheaten bread. It was the country where life was comfortable, easy, and happy. It was the granary of the Mediterranean, the great supply-store of Rome. But their senseless craving for gold led them to ruin provinces, in which, nevertheless, they counted upon settling. They behaved in Africa as they had behaved in Rome under Alaric. By way of tearing gold out of the inhabitants, they tortured them as they had tortured the wealthy Romans. They invented worse ones. Children, before their parents' eyes, were sliced in two like animals in a slaughterhouse. Or else their skulls were smashed against the pavements and walls of houses.

The Church was believed to be very rich; and perhaps, as it had managed to comprise in its domains the greatest part of the landed estates, it was upon it chiefly that the Barbarians flung themselves. The priests and bishops were tortured with unheard-of improvements of cruelty. They were dragged in the rear of the army like slaves, so that heavy ransoms might be extracted from the faithful in exchange for their pastors. They were obliged to carry the baggage like the camels and mules, and when they gave out the Barbarians prodded them with lances. Many sank down beside the road and never rose more. But it is certain that fanaticism added to the covetousness and ferocity of the Vandals. These Arians bore a special grudge against Catholicism, which was, besides, in their eyes, the religion of the Roman domination. This is why they made their chief attacks on basilicas, convents, hospitals, and all the property of the Church. And throughout the country public worship was stopped.

In Hippo, these atrocities were known before the Barbarians arrived. The people must have awaited them and prepared to receive them with gloomy resignation. Africa had not been tranquil for a century. After the risings of Firmus and Gildo, came the lootings of the southern Nomads and the Berber mountaineers. And it was not so long since the Circoncelliones were keeping people constantly on the alert. But this time everybody felt that the great ruin was at hand. They were stunned by the news that some town or fortified place had been captured by the Vandals, or that some farm or villa in the neighbourhood was on fire.

Amid the general dismay, Augustin did his best to keep calm. He, indeed, saw beyond the material destruction, and at every new rumour of massacre or burning he would repeat to his clerics and people the words of the Wise Man:

"Doth the firm of heart grieve to see fall the stones and beams, and death seize the children of men?"

They accused him of being callous. They did not understand him. While all about him mourned the present misfortunes, he was already lamenting over the evil to come, and this clear-sightedness pained him more than the shock of the daily horrors committed by the Barbarians. His disciple Possidius, the Bishop of Guelma, who was with him in these sad days, naively applied to him the saying out of Ecclesiastes: "In much wisdom is much grief." Augustin did really suffer more than others, because he thought more profoundly on the disaster. He foresaw that Africa was going to be lost to the Empire, and consequently to the Church. They were bound together in his mind. What was there to do against brutal strength? All the eloquence and all the charity in the world would be as nothing against that unchained elemental mass of Vandals. It was as impossible to convert the Barbarians as it had been to convert the Donatists. Force was the only resource against force.

Then in despair the man of God turned once more to Cæsar. The monk appealed to the soldier. He charged Boniface, Count of Africa, to save Rome and the Church.

This Boniface, a rather ambiguous personage, was a fine type of the swashbuckler and official of the Lower-Empire. Thracian by origin, he joined the trickery of the Oriental to all the vices of the Barbarian. He was strong, clever in all bodily exercises like the soldiers of those days, overflowing with vigour and health, and even brave at times. In addition, he was fond of wine and women, and ate and drank like a true pagan. He was married twice, and after his second marriage he kept in the sight and knowledge of everybody a harem of concubines. He was sent, first of all, to Africa as a Tribune—that is to say, as Commissioner of the Imperial Government, probably to carry out the decrees of Honorius against the Donatists; and ere long he was made commander of the military forces of the province, with the title of Count.

In reality, while seeming to protect the country, he set himself to plunder it, as the tradition was among the Roman officials. His officium, still more grasping than himself, persuaded him to deeds which the Bishop of Hippo, who was, however, anxious to remain on the right side of him, protested against by hints. Boniface was obliged to overlook much robbery and pillage on the part of his subordinates so as to keep them faithful. Moreover, he himself stole. He was bound to close his eyes to the depredations of others, that his own might be winked at. Once become the accomplice of this band of robbers, he had no longer the authority to control them.
