The great Danish invasion of the ninth century was successful, since it gave half of England to the Pagans. It is a sad thing to contemplate. Civilization was doubtless retarded. Whole districts were depopulated, and monasteries and churches were ruthlessly destroyed, with their libraries and works of art. This could not have happened without a fearful demoralization among the Saxons themselves. They had become prosperous, and their wealth was succeeded by vices, especially luxury and sloth. Their wealth tempted the more needy of the adventurers from the North, who succeeded in their aggressions because they were stronger than the Saxons. So slow was the progress of England in civilization. As soon as it became centralized under a single monarch, it was subjected to fresh calamities. It would seem that the history of those ages is simply the history of violence and spoliations. There was the perpetual waste of human energies. Barbarism seemed to be stronger than civilization. Nor in this respect was the condition of England unique. The same public misfortunes happened in France, Germany, Italy, and Spain. For five hundred years Europe was the scene of constant strife. Not until the Normans settled in England were the waves of barbaric invasion arrested.
The Danish conquest made a profound impression on Alfred, and stimulated him to renewed efforts to preserve what still remained of Christian civilization. His whole subsequent life was spent in actual war with the Northmen, or in preparations for war. It was remarkable that he succeeded as well as he did, for after all he was the sovereign of scarcely half the territory that Egbert had won, and over which his grandfather and father had ruled. He preserved Wessex; and in preserving Wessex he saved England, which would have been replunged in barbarism but for his perseverance, energy, and courage. That Danish invasion was a chastisement not undeserved, for both the clergy and the laity had become corrupt, had been enervated by prosperity. The clergy especially were lazy and ignorant; not one in a thousand could write a common letter of salutation. They had fattened on the contributions of princes and of the credulous people; they saw the destruction of their richest and proudest abbeys, and their lands seized by Pagan barbarians, who settled down in them as lords of the soil, especially in Northumbria. But Alfred at least arrested their further progress, and threw them on the defensive. He knew that the recovery of the conquests which the Saxons had made was a work of exceeding difficulty. It was necessary to make great preparations for future struggles, as peace with the Danes was only a truce. They aimed at the complete conquest of the island, and they sought to rouse the hostility of the Welsh.
Alfred showed a wise precaution against future assaults in constructing fortresses at the most important points within his control. Before his day the Saxons had but few fortified positions, and this want of forts had greatly facilitated the Danish conquest. But the Danes, as soon as they gained a strong position, fortified it, and were never afterwards ejected by force. Probably Alfred took the hint from them. He rebuilt and strengthened the fortresses along the coast, as he had four precious years of unmolested work; and for this his small kingdom was doubtless severely taxed. He imported skilled workmen, and adopted the newest improvements. He made use of stone instead of timber, and extended his works of construction to palaces, halls, and churches, as well as castles. So well built were his fortifications, that no strong place was ever afterwards wrested from him. In those times the defence of kingdoms was in castles. They marked the feudal ages equally with monasteries and cathedral churches. Castles protected the realm from invasion and conquest, as much as they did the family of a feudal noble. The wisdom as well as the necessity of fortified cities was seen in a marked manner when the Northmen, in 885, stole up the Thames and Medway and made an unexpected assault on Rochester. They were completely foiled, and were obliged to retreat to their ships, leaving behind them even the spoil they had brought from France. This successful resistance was a great moral assistance to Alfred, since it opened the eyes of bishops and nobles to the necessity of fortifying their towns, to which they had hitherto been opposed, being unwilling to incur the expense. So it was not long before Alfred had a complete chain of defences on the coast, as well as around his cities and palaces, able to resist sudden attacks,–which he had most to fear. His great work of fortification was that of London, which, though belonging to him by the peace of Wedmore, was neglected, fallen to decay, filled with lawless bands of marauders and pirates, and defenceless against attack. In 886 he marched against this city, which made no serious resistance; rebuilt it, made it habitable, fortified it, and encouraged people to settle in it, for he foresaw its vast commercial importance. Under the rule of his son Ethelred, it regained the pre-eminence it had enjoyed under the Romans as a commercial centre.
Having done what he could to protect his dominion from sudden attacks, Alfred then turned his attention to the reorganization of his army and navy. Strictly speaking he had no regular army, or standing force, which he could call his own. When the country was threatened the freemen flew to arms, under their eorls and ealdormen; and on this force the king was obliged to rely. They sometimes acted without his orders, obeying the calls of their leaders when danger was most imminent. On the men in the immediate neighborhood of danger the brunt of the contest fell. Nor could levies be relied upon for any length of time; they dwindled after a few weeks, in order to attend to their agricultural interests, for agriculture was the only great and permanent pursuit in the feudal ages. Everything was subordinate to labors in the field. The only wealth was in land, except what was hoarded by the clergy and nobles.
How well Alfred paid his soldiers it is difficult to determine. His own private means were large, and the Crown lands were very extensive. One-third of his income was spent upon his army. But it is not probable that a large force was under pay in time of peace; yet he had always one third of his forces ready to act promptly against an enemy. The burden of the service was distributed over the whole kingdom. The main feature of his military reform seems to have been in the division of his forces into three bodies, only one of which was liable to be called upon for service at a time, except in great emergencies. In regard to tactics, or changes in armor and mode of fighting, we know nothing; for war as an art or science did not exist in any Teutonic kingdom; it was lost with, the fall of the Roman Empire. How far Alfred was gifted with military genius we are unable to say, beyond courage, fertility of resources, activity of movement, and a marvellous patience. His greatest qualities were moral, like those of Washington. It is his reproachless character, and his devotion to duty, and love of his people which impress us from first to last. As has been said of Marcus Aurelius, Alfred was a Saint Anselm on a throne. He had none of those turbulent and restless qualities which we associate with mediaeval kings. What a contrast between him and William the Conqueror!
Alfred also gave his attention to the construction of a navy, as well as to the organization of an army, knowing that it was necessary to resist the Northmen on the ocean and prevent their landing on the coast. In 875 he had fought a naval battle with success, and had taken one of the ships of the sea-kings, which furnished him with a model to build his own ships,–doing the same thing that the Romans did in their early naval warfare with the Carthaginians. In 877 he destroyed a Danish fleet on its way to relieve Exeter. But he soon made considerable improvement on the ships of his enemies, making them twice as long as those of the Danes, with a larger number of oars. These were steadier and swifter than the older vessels. As the West Saxons were not a seafaring people, he employed and munificently rewarded men from other nations more accustomed to the sea,–whether Frisians, Franks, Britons, Scots, or even Danes. The result was, he was never badly beaten at sea, and before the end of his reign he had swept the coast clear of pirates. Within two years from the treaty of Wedmore his fleet was ready for action. He was prepared to meet the sea-kings on equal terms, and in 882 he had gained an important naval battle over a fleet that was meditating an invasion.
In the year 885 the Danes again invaded England and laid siege to Rochester, but fled to their ships on the approach of Alfred. They were pursued by the Saxon king and defeated with great slaughter, sixteen Danish vessels being destroyed and their crews put to the sword. Nor had Guthrun Athelstan, the ex-viking, been true to his engagements. He had allowed two additional settlements of Danes on the East Anglian coasts, and had even assisted Alfred's enemies. Their defeat, however, induced him to live peaceably in East Anglia until he died in 890. These
