Halfdan took Reading

King Aethelred and his brother Alfred attempted to lay siege to Reading but the Vikings had fortified the town with a dyke and palisade and the Saxons were defeated by the Vikings.
871 (8th January)

This was another battle between the Vikings led by Halfdan and the forces of King Aethelred and his brother, Alfred. The Saxons won the battle and Bagsecg, leader of the Great Summer Army, was killed.

Halfdan succeeded Bagsecg as King of Jutland and Wendland in Denmark.

Alfred became King when his brother Aethelred died. Aethelred’s two young sons, Aethelwold and Aethelhelm, were considered too young to take the throne.
871 (early Summer)
Battle of Wilton
The Saxons led by Alfred were defeated by the Vikings led by Halfdan.
872 (during)
Alfred paid the Vikings to stop attacking Wessex. The agreement was that the Vikings would leave Wessex alone for five years.

An uprising in Northumbria overthrew the Viking puppet King Ecgbert. The Viking force established a new base in Lindsey and quickly suppressed the Northumbrian revolt.
873 (during)
The Viking force moved to Mercia and captured Repton.
874 (during)
The Vikings led by Halfdan conquered Mercia. King Burghred was expelled. A puppet King, Ceolwulf was installed.
874 (during)
The Great Heathen Army split. Halfdan took his section north while Guthrum took the remainder south.
875 (late)
The Viking force led by Guthrum attacked Wessex and took Wareham (Dorset). Alfred lay siege to Wareham but a new Viking force of around 120 ships was seen off the coast meaning success was unlikely.
876 (during)
The Vikings led by Halfdan began dividing up Northumbria preparing to settle the land permanently.
876 (during)
Alfred made a deal with Guthrum, leader of the Vikings and demanded hostages in return for peace. But Guthrum did not keep the deal, he killed his Saxon hostages and moved to Exeter, leaving the Viking ships at Wareham.
876 (during)
A freak storm destroyed a large number of Guthrum’s ships moored off Wareham and a large number of Vikings were drowned. This allowed Alfred to leave Wareham and march to Exeter where he forced Guthrum to surrender. Guthrum then moved to Gloucester.

Guthrum left Wessex.
878 (6th January)
Guthrum returned with a large force and marched on Chippenham where Alfred was resident. Most of the town’s inhabitants were killed but Alfred managed to escape. It is likely that this was the last straw for the Witan and that Alfred lost their support due to the fact that his attempts to pay off the Vikings had not worked. Alfred was forced to leave Wessex in fear for his life. He sought refuge in the Somerset marshes at Athelney.
878 (Spring)
A large Viking force led by Ubba approached Contisbury Hill in North Devon where Earldorman Odda and his fyrd were inside the fort. Odda and his men surprised the Vikings by breaking out of the fort and attacking. The Vikings suffered heavy losses and Ubba was killed.

Guthrum was unable to make further progress into Wessex since Alfred adopted a tactic of using guerilla warfare.

Battle of Edington
Guthrum was defeated by King Alfred’s army. He was forced to accept baptism and peace terms. The Treaty of Wedmore recognised Danish occupation of England north of the line from London to Chester. Guthrum was to withdraw to behind this line and be recognised as King of his own independent kingdom. Guthrum’s new Danish Kingdom in England was subject to new laws called Danelaw.
