But the peace was not of very long duration, for the king of the Scots raised the standard of revolt, and the old Chronicler, or perhaps a successor, tells us that in the year 933, "Athelstan went into Scotland, as well with a land army as with a fleet, and ravaged a great part of it." This defeat of the Scottish king for a time restored Athelstan's dominion, but the peace which followed was, four years afterwards, broken by a powerful combination of Athelstan's enemies, which shook the "overlordship" of the English monarch to its foundation, and threatened the safety of his inherited kingdoms. The Scots, the Cumbrian Britons, the North and West Welsh, entered into a league with Anlaf of Dublin and the Danish chiefs of Northumbria and their Scandinavian allies to lower the prestige of the English monarch, and to seat the son of Sihtric on the throne of his ancestors. This fierce conflict culminated in the great battle of Brunanburh, in the year 937, in which, after a desperate two days' struggle, the confederate forces of his enemies were utterly routed, and Athelstan reigned supreme monarch to the end of his kingly career.

There is some difficulty in determining the exact date of this celebrated engagement. Sharon-Turner gives it as 934. Worsaae in his "Danes and Norwegians in England," says 937. Ethelwerd's Chronicle says 939. Sharon-Turner refers to the fact that one MS. of the Anglo-Saxon Chronicle gives the date 937, notwithstanding which he prefers 934. Dr. Freeman in his "Old English History" adheres to 937, which seems to be the most probable date.

We find that British Christians, as on previous occasions, espoused the cause of the heathen Danes, rather than fraternize with their hated Anglo-Saxon rivals, the disciples of Augustine and Paulinus. Thus many elements combined to render this battle one of the bloodiest and most destructive ever fought on British soil. The great struggle did not take place immediately on the arrival of Anlaf and his allies. Athelstan's two governors, Gudrekir and Alfgeirr first confronted the invaders. The former was slain and the latter fled to his sovereign, with the news of their discomfiture. Athelstan, with wise forethought, tried the effect of diplomacy, if only for the purpose of gaining sufficient time for the assembling of all his forces before staking his sovereignty upon the issue of a single battle.

The authorities, contemporary or nearly so, for the details of this decisive campaign, although meagre in comparison with those of more recent struggles, are nevertheless fuller than usual for the period. We have the poem in the Anglo-Saxon Chronicle, a notice in Ethelwerd's Chronicle, and some Scandinavian accounts, notably Egil's Saga. Sharon-Turner, however, regards the northern authorities as not entitled to implicit reliance, as their great object was the laudation of Egil and Thorolf, Scandinavian mercenaries in the pay of Athelstan, who, they contend, mainly contributed to the victory by the annihilation of the "disorderly Irish" contingent.

Athelstan, when his diplomatic finesse had answered his purpose, suddenly appeared at Brunanburh, and pitched his camp in front of the enemy. It is related that Anlaf, taken by surprise, imitated Alfred's stratagem, and entered the royal camp in the disguise of a harper. He was admitted into the presence of Athelstan, who was ever liberal in his patronage of poets and musicians, and the Danish king played, sang, and danced before the assembled chieftains, at a banquet, in the enjoyment of which he found them engaged previously to the holding of a council of war. On his dismissal a purse, filled with silver groats, was given to him as a reward for his services. Anlaf's observant military eye had detected the weakest point in his adversary's position, and the exact locality in which the royal tent was pitched, and he determined to surprise the camp by a sudden night attack, and either slay or carry off the king a prisoner. One false step, however, robbed him of the advantage his daring had gained. On leaving the enemy's lines, he was observed by a sentinel, who had formerly served under him, to bury the king's gratuity, which he disdained to appropriate to other use, in a hole in the earth. This aroused the soldier's suspicion, and Athelstan was informed of the circumstance. The king, in the first instance, was disposed to treat the man somewhat harshly, and demanded why the information as to the identity of the pretended itinerant minstrel had not been communicated to him before his departure. To this the faithful soldier replied, "Nay, by the same oath of fealty which binds me to thee, O king, was I once bound to Anlaf; and had I betrayed him, with equal justice mightest thou have expected treachery from me. But hear my counsel. Whilst awaiting further reinforcements, take away thy tent from the spot upon which it now stands, and thus mayest thou ward off the blow of thine enemy." This advice Athelstan followed, and shortly afterwards the Bishop of Sherborne arrived with his contingent, and pitched his tent in the locality vacated by his royal master, which circumstance cost him his life during the night surprise which followed. We have Alfred's harper story on the authority of Ingulf and William of Malmesbury, the former of whom was born in 1030, and the latter in 1095 or 1096, so that they were recording events which had transpired between one and two centuries before their own adult experience. The Anlaf tale is too exact a counterpart of the one related about Alfred, not to suggest doubt as to its veracity; or, if it be a veritable incident in the life of the Scandinavian warrior, the doubt will have to be transferred to the story related of his Saxon predecessor. It is not very probable so transparent an artifice would succeed a second time, especially when played upon such a clear-headed chieftain as Alfred's grandson.[35] But, however Anlaf gained his information, the night the attack took place, Adils, a Welsh prince, detected the strategy of Athelstan. After the death of the Bishop of Sherborne, he and Hyngr (a chieftain described in Egil's Saga as a Welshman, but whose name, Sharon-Turner thinks, sounds very like a Danish one), led the attack on the main body of the English army. But Athelstan was prepared, and Thorolf and Alfgeirr's detachments were instantly opposed to them. Alfgeirr was soon overpowered and fled, on perceiving which Thorolf threw his shield behind him, and hewed his way with his heavy two-hand sword through the opposing mass until he reached the standard of Hyngr. A few moments decided the fate of that chieftain. Thorolf ordered Egil, though weakened by the defeat and flight of Alfgeirr, to resist Adils, but to be prepared to retreat to the cover of a neighbouring wood, if necessary. Adils, mourning the death of his colleague, at length gave way, and the preliminary nocturnal combat ended. After a day's rest,[36] Egil led the van of the Anglo-Saxon army, and Thorolf opposed the "irregular Irish," which formed part of Anlaf's own division, and extended to the wood previously mentioned. Turketal, the English chancellor, a man of stalwart proportions, who commanded the citizens of London, and Singin of Worcestershire, were opposed to Constantine, king of the Scots, while Athelstan, at the head of his West Saxons, confronted Anlaf in person. Thorolf attempted to turn the enemies' flank, when Adils rushed from his ambush in the wood, and countered the movement. Egils saw with dismay Thorolf's banner retreating. He knew by this that he must have fallen; and, rushing to the spot, he rallied the scattered band, successfully renewed the attack, and, in Sharon-Turner's words, "sacrificed Adils to the manes of Thorolf." The Councillor pierced the enemy's centre, heedless of the arrows and spears which fastened on his armour. Constantine and he met and fought hand to hand for some time, and Singer slew the prince, his son, who fought valiantly by his father's side. This vigorous and successful onslaught produced a panic among the Scots, and correspondingly elated the English. In the meanwhile Athelstan and his brother, Edmund, the Atheling, were engaged with the main body of the enemy under Anlaf. The grandson of the Great Alfred and the presumed grandson of Radnor Lodbrog contended both for dominion and renown. In the midst of the fight Athelstan's sword-blade snapped near the handle. Another was supplied to him, it was said, by miraculous agency, which saved his life. At length the tremendous struggle, which lasted throughout the day, was brought to a close by Turketal chasing the Scots from the battle-field, and turning Anlaf's flank. Immense slaughter ensued; the enemy's ranks began rapidly to thin; the English shouted "victory!" and Athelstan, profiting by the auspicious opportunity, ordered his banner to the front, and by a determined and well-directed onslaught, broke the enemy's now enfeebled ranks. They fled in various directions, and, according to Egil's saga, "the plain was filled with their bodies." Anlaf and his immediate followers narrowly escaped to their ships and embarked for Ireland. Sharon-Turner says—

"Thus terminated this dangerous and important conflict. Its successful issue was of such consequence, that it raised Athelstan in the eyes of all Europe. The kings of the continent sought his friendship, and England began to assume a majestic port amid the other nations of the west. Amongst the Anglo-Saxons it excited such rejoicings that not only their poets aspired to commemorate it, but the songs were so popular, that one of them is inserted in the Saxon Chronicle as the best memorial of the event."

The following is Dr. Giles's literal rendering of this remarkable poem into modern English:—

A. 937.—Here Athelstan, king,
of earls the lord,
of heroes the bracelet giver,
and his brother eke,
Edmund etheling,
life-long glory
in battle won
with edges of swords
near Brunanburh.
The board-walls they clove,
they hewed the war-lindens,

Hamora lafan'
offspring of Edward,
such was their noble nature
from their ancestors,
that they in battle oft
'gainst every foe
the land defended,
hoards and homes.
The foe they crushed,
the Scottish people
and the shipmen
fated fell.
The field 'dæniede'
with warriors' blood,
since the sun up
at morning tide—
mighty planet—
glided o'er grounds,
God's candle bright,
the eternal Lord's—
till the noble creature
sank to her settle.
There lay many a warrior
by javelins strewed;
northern men
over shield shot;
so the Scots, eke,
weary, war-sad.
West Saxons onwards
throughout the day,
in bands,
pursued the footsteps
of the loathed nations.
They hewed the fugitives
behind, amain,
with swords mill-sharp.
Mercians refused not
the hard hand-play
to any heroes
who, with Anlaf,
over the ocean,
in the ship's bosom,
this land sought
fated to the fight.
Five lay
on the battle-stead,
youthful kings,
by swords in slumber laid:
so seven, eke,
of Anlaf's earls;
of the army countless,
shipmen and Scots.
There was made flee
the North-men's chieftain,
by need constrained,
to the ship's prow
with a little band.
The bark drove afloat;
the king departed,
on the fallow flood
his life preserved.
So there, eke, the sage
came by flight
to his country north,
Constantine,
hoary warrior.
He had no cause to exult
in the communion of swords.
Here was his kindred band
of friends o'erthrown
on the folk-stead,
in battle slain;
and his son he left
on the slaughter-place
mangled with wounds,
young in the fight.
He had no cause to boast,
hero grizzly haired,
of the bill-clashing,
the old deceiver;
nor Anlaf the moor,
with the remnant of their armies;
they had no cause to laugh
that they in war's works
the better men were
in the battle-stead,
at the conflict of banners,
meeting of spears,
concourse of men,
traffic of weapons,
that they on the slaughter-field
with Edward's
offspring played.
