The Viking age gave us some of the most iconic battles in British history. There was Edington, Alfred the Great’s against-the-odds triumph in AD 878 over part of a massive Danish invasion force; Brunanburh (AD 937) in which Alfred’s grandson Æthelstan stamped his authority on the British Isles; and Stamford Bridge (1066), where the bones of Harald Hardrada’s Viking army were left to whiten on the field, picked clean by carrion birds.
But the Viking age lasted for almost three centuries: from the end of the eighth until deep into the 11th. Over this period, in England alone, sources document at least 50 pitched battles, plus as many raids, sieges and naval encounters. Most of these have been all but forgotten over the centuries.
Many of them, however, played a critical role in shaping the nascent kingdoms of England and Scotland. Here, then, are five battles of the Viking age: clashes that – though uncelebrated and often unremembered – helped to shape the destiny of Britain.

The battle of Hengest’s Hill (AD 838)
The crushing of the Cornish
Combatants: A Cornish–Viking alliance against Egbert’s kingdom of Wessex
Outcome: Victory for Wessex
King Egbert of Wessex was not a man to be trifled with. In AD 825, he established himself and his kingdom as the pre-eminent power in Britain, crushing the Mercians at a place called Ellendun, just outside Swindon. It was a memorably bloody business. A fragment of poetry recalled that “Ellendun’s stream ran red with blood, was stuffed up with corpses, filled with stink”.
This was only one front in Egbert’s campaign to subdue the other kingdoms of Britain. In AD 815, he had raided Cornwall “from east to west” – a reminder to the still independent Cornish kingdom of the limits of their autonomy. In AD 838, however, the Cornish decided that the time had come to push back against West Saxon domination. This time they had allies – Viking allies.
The Anglo-Saxon Chronicle records that, in AD 838, a “great ship-horde came to Cornwall”, which combined forces with the native Cornish and immediately set about challenging King Egbert’s power. Egbert led an army into Cornwall, bringing his strength to bear at a place called Hengest’s Hill. This was most probably Kit Hill, the massive prominence that dominates the valley of the Tamar, one flank of which is still known as Hingsdon.
We know very little about what happened, except that the Vikings and the Cornish were put to flight. This was to be the last gasp of Cornish independence. The people of Britain’s south-western peninsula would never again pose a military threat to the Anglo-Saxon kingdoms. The same cannot be said of their erstwhile Viking allies.
Since the AD 790s, Viking fleets had been striking from the sea without warning, raiding monasteries and coastal settlements and capturing slaves and treasure. By the AD 830s, these attacks had become increasingly brazen, targeting substantial settlements like Carhampton in Somerset and defeating Anglo-Saxon armies. But this was the first time (that we know of) that Vikings had marched to war alongside a native people in Britain. Although (and sadly for the Cornish) it was not a successful experiment, it would certainly not be the last.

The battle of Cynwit (AD 878)
Ravens and ramparts
Combatants: Odda and the men of Devon against the Vikings
Outcome: Victory for Wessex
In AD 878, things were looking grim for Egbert’s grandson, King Alfred. A Viking army, led by the warlord Guthrum, had burst into Wessex, occupying Chippenham and driving Alfred into exile in his own kingdom.
For several months the king was on the run, living as a fugitive in the marshes and wild places. Eventually he set up camp on the Isle of Athelney in Somerset, from where he orchestrated guerrilla raids on the Viking occupiers. When, however, another Viking army, led by the warrior Ubbe, arrived in the south-west of England, it must have seemed likely that the days of the West Saxon dynasty were numbered in double-digits.
Ubbe’s army was met by forces commanded by Odda, the ealdorman of Devon. The battle that followed, one of the great military reversals of the early Middle Ages, was fought at an unidentified hillfort in the south-west of England called ‘Cynwit’. King Alfred’s biographer, Bishop Asser of Sherborne, explained how the West Saxons, having retreated within the earthen ramparts of the fortress, found themselves trapped inside by the Viking army without food or water. But, as Asser tells it, rather than allow themselves to become enfeebled by a siege, the West Saxons chose to seek victory or a glorious death. At dawn, they hurled themselves down the slopes towards their erstwhile besiegers, overwhelming them with their ferocity and driving the survivors to their ships. Perhaps 1,200 Viking warriors, including Ubbe, were slain.
Defeat for the Vikings was made worse for them by the capture of their raven banner – a magical talisman (said to have been woven by Ubbe’s three sisters, the daughters of the semi-legendary Ragnar ‘Hairy-pants’) that was believed to foretell victory if the raven’s wings caught the wind before battle. Its loss was a bad omen for the Vikings in Wessex.
Alfred would go on to win a famous victory over the Viking forces of Guthrum at Edington in Wiltshire, setting the West Saxon royal house on a path that would lead to the throne of a united kingdom of England. Had it not been for the victory at Cynwit, Alfred – caught between Ubbe and Guthrum – might have met a very different fate indeed.
The battle of the Holme (AD 902)
Æthelwold perishes in the fens
Combatants: King Edward against his rebel cousin and the Vikings
Outcome: (Sort of) Viking victory
Violence between Anglo-Saxons and Vikings didn’t end with Alfred’s death in AD 899. In fact, no sooner had Alfred’s son, Edward, taken his seat on the throne than he was facing a military crisis. Alfred’s nephew, Æthelwold – feeling that he had been unfairly passed over – rebelled against his cousin Edward before fleeing to the parts of England under Viking control (swathes of the north and east of the country sometimes referred to as ‘the Danelaw’). There he was apparently welcomed with open arms and acclaimed as “king of the pagans; king of the Danes”.
Æthelwold began his campaign in the summer of AD 902, bringing an army out of Viking East Anglia and harrying throughout southern England as far as Cricklade and Braydon in Wessex. This was a provocation, and Edward (known later as ‘the Elder’) wasted little time in assembling an army to pursue his cousin back into the bleak and unforgiving fens of East Anglia.
The battle that followed was fought in a place known as the Holme (‘island’) and was a catastrophe for almost everyone concerned. Edward, perhaps realising the difficulties of the terrain, ordered a retreat, but the Kentish contingent refused the summons. In mounting panic, Edward dispatched rider after rider (seven in total) to order his men to fall back. For reasons we will never know, they failed to withdraw.
The only description we have of the fighting proclaims grandly that the belligerents “clashed shields, wielded swords, and shook greatly the spear in either hand”. But to fight in the sucking peat marshes of the fens would have been to live through a waking nightmare. When the men of Kent broke and ran, throwing aside shields and weapons in their desperation, they would have slipped and fallen, trampled in the clawing fens, drowning in mud and brackish bog-water, floundering through the reed-beds into disaster. And, for the men of Kent, disaster it assuredly was: the Kentish ealdorman Sigewulf, and his kinsman Sigehelm, and almost all of the Kentish lords were slain.
For King Edward, however, there was a silver lining: Æthelwold, the pretender, was dead. Who can say what the future might have held in store for Æthelwold had he emerged from Holme victorious. Instead, a serious challenge to Edward’s authority and legitimacy had been removed, and it would be he – Edward – who in the subsequent decades would go on the offensive, conquering all of Viking-held England south of the Humber.
The battle of Stainmore (AD 954)
Bloodaxe’s final stand
Combatants: Eric Bloodaxe and King Eadred of Wessex
Outcome: Northumbria loses its independence
The battle of Stainmore might not have been a battle at all, but it was remembered as one by those who came after – the last breath of independence of the ancient kingdom of Northumbria.
Northumbria had been under Viking domination since AD 866 when the city of York was captured by the Viking micel here (‘great horde’). Over the following nine decades, Scandinavian culture had seeped into many aspects of life in England’s most northerly realm, changing habits of language, dress, belief and identity. But the Northumbrians remained a proud people with a long and distinguished history and, if pushed, they preferred a foreign Viking king to the heavy hand of the West Saxon dynasty. And in the mid-10th century this was precisely what they ended up with when the former king of Norway, Eric Bloodaxe, occupied the Northumbrian throne.
King Eric was not a good man. He had earned his nickname by killing off most of his own brothers to become king of Norway, and he was so brutal and unpopular as king that he was swiftly kicked out by his surviving brother, Haakon ‘Athelstan’s-foster-son’ (a man who, as his nickname suggests, grew up in the English court of King Æthelstan, Edward the Elder’s son). Eric fled to England and, though we don’t know how he managed it (bloody axes may well have been involved), convinced the Northumbrians to adopt him as their king. He proved just as unsuccessful in Northumbria as he had been in Norway, getting kicked out in AD 948 for upsetting King Eadred of Wessex (by slaughtering a West Saxon army at Castleford).
In AD 952 Eric was invited back by the Northumbrians when Eadred wasn’t looking, but in AD 954 he was shown the door for a second time. He travelled west over the Pennines, taking the Stainmore pass through the hills towards Cumbria – striking, perhaps, for the Irish Sea. He never arrived. According to English sources, Eric died a squalid death on the road, “treacherously killed by Earl Maccus”.
But Scandinavian sources tell a different story: that Eric met his foes at the head of an outnumbered army and there on the high, wind-scoured pass, he died the glorious death of the archetypal Viking warlord. A poem commissioned by his wife pictured Eric arriving at Valhalla, welcomed by Valkyries, to feast and fight by Odin’s side until the breaking of the world: a fitting epitaph for the last king of an indepen- dent Northumbria.
The battle of Dane’s Wood (1016)
Carnage in the shadow of the forest
Combatants: Cnut Sveinsson and Edmund Ironside
Outcome: Cnut and Edmund make peace
The year 1016 was a bloody one. It saw the Anglo-Saxon king Edmund ‘Ironside’ taking up the sword wielded so ineffectively by his father, Æthelred the Unready, and standing resolute against the challenge posed by the Danish prince, Cnut Sveinsson. Edmund and Cnut met in battle no fewer than seven times that year – six of these clashes are well known, but the final one was almost lost to history.
Cnut’s father, Svein Forkbeard, had briefly made himself king of England in the winter of 1013/14. Svein had died suddenly – slain, so it was said, by the murderous ghost of St Edmund, the king of East Anglia martyred by the Vikings in AD 869 – and the English crown had reverted to the West Saxon dynasty. Cnut, however, was not a man to drop a claim to power lightly.
In 1016, Cnut and Edmund fought major battles at Penselwood (Somerset), Sherston (Wiltshire), London, Brentford (Middlesex) and Otford (Kent). Edmund prevailed against the Danish challenger in all of these struggles (apart from Sherston, which had ended in stalemate), and it must have seemed that Cnut’s campaign was on the brink of sputtering out.
But at Assandun (probably Ashingdon in Essex), the Danish warlord brought his army to bear once more, and – thanks to the disloyalty of the perfidious West Saxon nobleman Eadric Streona (who fled at the beginning of hostilities) – Cnut pulled off a stunning victory. It was a calamity for the English. As the Anglo-Saxon Chronicle reported it: “There Bishop Eadnoth was killed, and Abbot Wulfsige, and Ealdorman Ælfric, and Godwine the ealdorman of Lindsey, and Ulfcetel of East Anglia, and Æthelweard, son of Ealdorman Æthelwine, and all of the English nobility was destroyed there.”
The battle of Assandun is generally assumed to have been the decisive moment of the war, and the event that paved the way for Cnut to eventually reclaim the throne prematurely vacated by his father. But Edmund was not yet dead, and there was to be one more battle before the English king would lay down his arms and come to terms. It is mentioned only in a single stanza of poetry composed in praise of Cnut by the Viking skald Ottar the Black: “Prince, you won fame with the sword north of mighty Danaskógar, and it seemed a slaughter to your followers.”
Danaskógar means ‘forest of the Danes’, and nowhere in England is known to ever have had such a name. However, it is known that Edmund had retreated with his army towards Gloucestershire, where – beyond the river Severn – the Forest of Dean might have provided arboreal refuge. It is possible that the Old Norse speakers of Cnut’s army, pursuing Edmund’s battered forces into these western woods, heard the word ‘Dean’ and interpreted it, not as Old English denu (‘valley’), but as Old English dena: ‘of the Danes’. Retranslated into Old Norse, the Forest of Dean became the Forest of the Danes – a place won and renamed with the sword.
In the aftermath, Edmund and Cnut made peace. Within a few months, Edmund was dead and Cnut succeeded him as king of all England.
