II. KING EADMUND OF THE EAST ANGLES, PART ONE
Eadmund, King of the East Angles
While scarce information is known about the invasion itself, the Anglo-Saxon Chronicle has this entry:
“A.D 867. This year the army rode over Mercia into East-Anglia, and there fixed their winter-quarters at Thetford. And in the spring King Eadmund fought with them, in which the East-Angles gained the victory; but at great cost, as the Danes had slew his brother. The name of his brother was Osweald…”
More light is shed on the ensuing conflict, with the Chronicle mentioning four battles of comparable importance occurring in East Anglia and the surrounding Fenlands as far as Mercia, with significant monarchs, notably Ælfred the Great of Wessex and Burghred of Mercia, both pledging fyrds to East Anglia’s defence.

East Anglia, thanks to the efforts of Eadmund’s strategic prowess, and his powerful, but short-time West Saxon allies, was spared from the Great Heathen Army’s conquest. However, the land was ravaged. With monasteries burned and villages pillaged, much of East Anglia’s tumultuous 9th-century history was lost. While East Anglia may have been successful in the defence of their realm, the same cannot be said for those north of the River Nene. The East Angles had only defeated a contingent of the Pagan onslaught, notably the armies led by the mythical Ivar ‘the Boneless.’ Mercia, particularly, had borne the brunt of the Great Heathen Army, and in their defeat, lost much of their eastern lands to the Danes. This land came to be known as the ‘Five Boroughs,’ consisting of Derby, Leicester, Lincoln, Nottingham and Stamford respectively. The Mercians would never see these lands returned as an independent kingdom.
The victories against the Great Heathen Army granted little but a short amount of reprieve from the Norse onslaught. Far outnumbered by the victorious northern army of the Danes, Eadmund had sent his firstborn son, the 1-month-old Æthelric to be a hostage of the Norse King of Northumbria, Halfdan Ragnarsson in late-September of 871.
While such unfortunate circumstances presented themselves to the King of the East Angles, progress was made in affirming a more long-term relationship with the West Saxons. Eadmund’s trusted diplomatic adviser, Beorhtric, had created a more amicable environment between the two monarchies, with both Ælfred and Eadmund convening in Winchester to forge a more unified front against repeated Northmen invasions. A little over a week later, Eadmund had pledged his nephew’s – the late Osweald’s son – future education in Ælfred’s hands. In the following nine months, a firm alliance was established between the West Saxons and the Angles, with the joint Anglo-Saxon
(aha!) victory against the Norse raid of Colchester in September of 872, and the subsequent betrothal of Eadmund’s second son, Beorn, and Ælfred’s daughter, Osburh in November affirming the practicality of such an alliance.
While providing Æthelric as a hostage to the Northmen may have achieved short-term goals of peace, it proved more troublesome to Eadmund by 873. As long as King Ragnarsson held his son hostage, he had all the cards. Any declaration of war – even to support his West Saxon allies – would result in a swift execution for the young Ætheling. When a call to arms was given to Eadmund by Ælfred in early-January of 875, in defence of southern England against the Northmen, Eadmund chose to sacrifice his son in favour of the alliance with Wessex. Expectedly, Æthelric was executed by Ragnarsson’s men six months before his fourth birthday.
On the eve of August, 875, Halfdan’s armies had sailed from Grimsby and made landfall in Bracklesham Bay, southwest of Chichester with 4,300 men at his command. This outnumbered Ælfred’s army by little over 1,000. While Eadmund’s own force consisted of roughly 1,250 men – this did not tip the scales by a significant margin – as Ragnarsson had negotiated an alliance with his brother and Swedish King, Björn Ironside. Ironside had command of roughly 5,000 men – and his arrival into the war caused an enormous tipping of the scales. While record of the Battle of Southwark is scarcely found – largely due to the destruction of many monasteries and villages in Wessex – it is nonetheless, a significant turning point in the war for England. From what is understood, the West Saxons suffered a great defeat at the hands of a hodgepodge of Polish mercenaries and Swedish warbands – all led by Björn Ironside.
Such a defeat prevented King Ælfred from relieving the siege of Winchester, with the city and the surrounding shire ravaged by pillaging Northmen and Polish mercenaries. The outcome of the siege being that Eadmund’s second son, Beorn, was captured during the sacking of the city. After the defeat at Southwark, Ælfred was forced to move his seat of government to Wareham for the remainder of his reign. Eadmund, instead of reinforcing his ally’s efforts to retake Winchester, had instead opted to strike the heartland of the Danes’ rule, and marched his armies through Stamford and Lincoln – employing a highly successful strategy of Chevauchée – whereupon he besieged York in July of 875. The siege lasted the duration of the year-long war, with the city captured 2 days before peace was agreed upon by both Ælfred and the Loðbrók brothers.
The defeat in Hampshire represented the momentum that the Great Heathen Army still carried with them, with small respite granted to the remaining independent realms. Eadmund, in particular, in the immediate aftermath of the war, began to prepare his armies to rebuff any future incursions into his Kingdom. In 878, Eadmund had issued a royal charter granting funds to develop Ipswich’s ports. However, this was rescinded in 880 in order to expand and reorganise his fyrd.
In early-May of 878, Eadmund’s third son, Beornwulf, was born, with his sister, Æthelflæd, born two years later. In this time, logistical matters were delegated to Eadmund’s trusted adviser, Beorhtric, Reeve of Sudbury – with the King lacking the patience to learn logistical matters himself.
In 881, after four years of relative peace, the calm of England swiftly erupted once more into violence. However, in this instance, it was not the Northmen who were the aggressors. Instead, the East Angles had come for vengeance. On the 20th of May, the West Saxons had pledged their forces to rebuff the Viking invaders. On the 23rd of May, Duke Otto of Saxony had heeded Eadmund’s call to war. Combined, Eadmund’s coalition of Anglo-Saxons and Germans had 5,700 men under their command. While impressive, this was, regardless, still dwarfed by the 9,000 men under both Halfdan and Ironside. The silver lining of the war, being Ironside's armies – consisting of roughly 70% of the Northmen’s total strength – needed to travel from Scandinavia to aid in Halfdan’s defence. Additionally, while officially part of the war, the Swedish already had military commitments in Finland during the same period. In this time, the joint Anglo-German armies won five important battles against the Great Heathen Army.
The Battle of Hertford, the largest and most important engagement, ended in an Anglo-German victory. Being the most notable battle of the war, it is described in great detail by scholars. Outnumbered 2:1, Halfdan’s army was intercepted in their march to Wessex. Having no cavalry of his own, Saxon mounts barreled downhill into their bowmen, causing a rout behind Halfdan’s forces. While his own infantry was engaged in fighting the Anglo-Saxon spear front, Eadmund’s Huscarls flanked Halfdan’s forces, causing an encirclement and subsequent slaughter of the Northmen. Out of the 3,000 Viking warriors entering the Battle of Hertford, only 400 escaped.
The four other battles, being the battles of Walsingham, Northampton, Blything and Radfield, all ended in an Anglo-German victory. The success of Eadmund and his allies had been unheard of since the defence of East Anglia in 869. However, this success had come to an end as swiftly as it began. In 883, Björn Ironside’s armies landed near York, consisting of the 5,000 men he had promised his brother. Marching south with Halfdan, this colossal force of Northmen came to be known as the ‘Great Summer Army,’ reinforcing the existing presence of the Danes in England. In late-August of 883, the Battle of Lincoln commenced. Ælfred and Eadmund’s armies were alone, with the Saxons departing for Germany to aid their liege in a Polabian invasion.
3,000 Anglo-Saxons, primarily under the command of Eadmund, met 7,000 Norse warriors in the fields outside Lincoln. Recently taking command of the settlement three days earlier, the Anglo-Saxon armies were caught off-guard by the incoming Viking force. Bloody fighting ensued, with the two Kings refusing to capitulate their gains in Danish Mercia. After a week of intense, intermittent fighting, the four Kings met out on the fields to draft a peace treaty for the war, ending the conflict on the 23rd of August, 883. The gains the Great Heathen Army had made in the 870s remained unchanged, but the war had significantly hampered any progress they may have made into East Anglia and Wessex, with a truce agreed upon for the time being.
Aftermath of Eadmund's War (881–883)
In 885, Ælfred of Wessex had negotiated an agreement with the Danes by the name of ‘the Treaty of Ælfred and Halfdan.’ This, among peaceful trade agreements and an establishment of an indiscriminate Weregild (‘Man-Price’) of both a Dane and Saxon, had determined the borders of Wessex and the ‘Danelaw,’ a catch-all term for the amalgamation of all Norse territories in England, and legitimising their claims to both Mercia and much land north of the Rivers Avon and Nene. Effectively, Ælfred had made himself King of all independent Anglo-Saxons. The following year, he had styled himself as such.
While this officialised Eadmund’s realm as de jure under the rule of Ælfred, Eadmund refused to acknowledge the existence of this treaty. While this had the foreseen consequence of the souring of relations between the West Saxons and East Angles, they had to – regardless of their feelings for one another – work together out of necessity. In November of 886, the King of Mercia, Burghred, had lost most of his realm to the famed Hæsteinn of Montaigu, his realm now officially only covering Bedfordshire – a far cry from what he inherited in 852.
In late-November of 886, there is evidence present that Eadmund had become the Overlord of the Mercian monarchy in Bedford, appointing a High Reeve of the shire in December of the same year. In February, King Burghred had disappeared, and Eadmund had officially become the Ealdorman of Bedford in February of 888. In June of that year, Hæsteinn of Montaigu declared himself King of Mercia, controlling the Northern and Western parts of the realm.
In July of 889, Halfdan of Northumbria raided and sacked Cambridge, taking gold and thralls from the King of the East Angles. This may have occurred as a result of the treaty officialising the Danelaw, as East Anglia was the last independent Anglo-Saxon monarchy, bowing to neither Wessex nor the Danelaw. Immortalised by the scribes of his court, Eadmund had vowed that this slight will not be left unavenged.
