During 869 the ‘Army’ streamed back to York, and it was now, perhaps, that they began to think of settling. But their restless and predatory instincts could not die down quickly, and in 870 the bulk of the host set forth again, ‘rode over Mercia into East Anglia, and made their winter quarters at Thetford.’ The great monasteries of the Fens, Peterborough, Ely, Crowland, and Bardney, went up in flames, and Eadmund of East Anglia, taken prisoner after a vain attempt at resistance, was murdered in cold blood. Though there is no authority earlier than Abbo (circa 980), the story is probably true, for shortly afterwards one finds his memory honoured, and churches raised to him by the very men who had murdered him, which could hardly have happened unless they had been deeply impressed by his heroic end. All East Anglia and Essex were soon in Danish hands, and the ‘Great Army’ prepared to advance against Wessex.

Ingvar and Hubba now pass from the scene, though Hubba reappears for a brief space some years later. The army that marched upon Wessex was led by Halfdene, another son of Ragnar, a second king named Baegsceg, and several jarls—a division of command which could hardly make for efficiency.

The defence of Wessex was in capable hands. The gallant King Aethelred was admirably assisted by his brother Alfred,[C] soon to be the greatest of English kings. Everything possible appears to have been done to facilitate mobilization, for the Wessex men were in the field with the least delay. Better still, there was no standing on the defensive; the royal brothers appear determined from the first to attack their foes and drive them out of the country.

[C] The name Alfred has become so much a part of English history that the time-honoured orthography is retained.

The Danish army advanced from Thetford to the Thames, contemptuously ignoring Mercia, and entrenched itself at Reading in the triangle formed by the junction of the Kennet with the Thames. The kings appear to have established this camp while the jarls began to ravage. But they were quickly to learn that they could not play the game with impunity. Three days after their arrival two of the jarls were attacked by the Berkshire fyrd, under Ealdorman Aethelwulf, at Englefield Green, in Windsor Forest, and defeated; one of them was slain. Four days afterwards the King and Alfred arrived at Reading unexpectedly with the army of Wessex. The Northmen were off their guard, and were driven back within the palisades. But when the English attempted to storm the camp they were heavily repulsed, with the loss of the brave Aethelwulf, and obliged to retreat westward.

The Viking host pursued. The retreat and pursuit went on for four days, until Aethelred and Alfred had called in reinforcements sufficient to enable them to fight again. Somewhere on Aesc-Dune (Ashdown)—i.e., the Berkshire Downs, a great battle was fought. It is impossible to locate the field; all that can be said is that it must have been a long distance west of Reading. The plan of the battle itself is quite clear, but the movements which preceded it are by no means so. It would appear that the army of Wessex, coming from the south or south-east, was halting before breasting the slopes of Aescdune when the Vikings suddenly crowned the heights. They were in two masses, one led by the kings, the other by the jarls. The English were also in two divisions, commanded respectively by Aethelred and Alfred. Alfred was already at the front, and he apparently made up his mind that it was far better to meet than to await a downhill charge. He gave the word for the whole army to advance, and informed his brother, who was hearing Mass in the rear. Aethelred, perhaps because he knew that matters were quite safe in his brother’s hands, and because at the price of a few minutes’ absence from the field he was quite ready to enhearten his superstitious followers by a little pious posing, declined to come until service was over. The story is probably true. Asser distinctly says that he had excellent authority for it, very likely that of Alfred himself.

The English uphill charge had the best effect. The Vikings were brought to a stand, and the fight raged furiously on the slopes of Aescdune, the focus of the fray being a stunted thorn, the only tree on the hillside. Alfred’s tactical insight had its reward, and the day went steadily in favour of the English. King Baegsceg and five jarls were slain, and the Northmen broke and fled headlong. They were pursued all night and into the next day, and Asser says that ‘many thousands’ of them were slain.

It is sad to record that this splendid victory had no results. Halfdene and the surviving jarls succeeded in reaching Reading, and only a few days later they were joined by large reinforcements from the Continent. Thus recruited, Halfdene again took the offensive, and fourteen days after Aescdune was able to fight Aethelred at Basing, this time with success. Still no decisive victory had been gained, and two months later the armies are found confronting one another at Marden, near Hungerford. Evidently the Northmen were still confined to the neighbourhood of Reading. The army of Wessex was formed in two divisions as at Aescdune, and for a great part of the day had the advantage, but in the end the Northmen were victorious. Aethelred himself was perhaps mortally wounded; certainly he died a few days after. His death would have been an irreparable loss but that his great brother was at hand to take up his sword.

The Northmen were now advancing into the heart of Wessex, and so heavy had been the losses in the campaign that it was a task of exceeding difficulty to reorganize the army. About a month after Marden Alfred took up a position at Wilton with the small force which he had been able to collect. Says Asser: ‘The Saxons had been worn out by eight battles in one year against the pagans, of whom they had slain one king, nine dukes, and innumerable troops of soldiers.’ Alfred and his little army made a gallant resistance, and for long beat back the assaults of their enemies; but the favourite Viking stratagem of a feigned retreat and a counter-attack turned the day against them. Defeated, and with the Northmen in the heart of his ancestral kingdom, Alfred was forced to sue for terms. The invaders also had suffered very severely, and were ready to depart for a time to some other more promising field of plunder. Asser and the Chronicle merely say that Alfred made peace with the pagans. We must assume that they were bought off with a subsidy. The respite could not be a long one—the Northmen of the ninth and tenth centuries were the most perjured of mankind—but Alfred might be trusted to turn the interval in the fighting to the best advantage.

The position of England at the end of 871 could scarcely have been worse. The results of the lack of national unity were terribly apparent. Northumbria and East Anglia had practically disappeared from the roll of English kingdoms; Mercia was tottering. Only Wessex had succeeded in retaining its independence, and was still ready to fight fiercely for liberty. The situation was similar to what it had been four centuries before, when the first assaults of the English, after occupying the east, were checked by Ambrosius and Artorius. But while the British leaders left no successors worthy of them, it was otherwise with Ecgberht and Aethelwulf. The youngest son of the latter was to be the greatest and noblest of English kings, and to pass on his sceptre to successors worthy of his name.
