After the battle at York, several other key battles occur during the series. The first is the battle where Alfred's brother (Æthelred), who was the king of Wessex, dies, although the Anglo-Saxons are successful in temporarily halting the Danish advance. There is truth to Alfred's brother perhaps being injured and killed in battle as depicted in the series. Rather than the son of Æthelred taking power, it was Alfred that was chosen, something unexpected and discussed in the series, as he was seen as more fit to rule.
However, the battle where Æthelred is fatally injured might be fictionalized or could based on several battles where the Anglo-Saxons did have some success in limiting the Danish advances. Still, Wessex failed to stop the Danes completely and had to pay off the Danes for temporary peace. The show depicts the peace conference between King Alfred and Ubba.<ref>For more on Alfred, see: Smyth, A. P. (1995). King Alfred the Great. Oxford ; New York: Oxford University Press.</ref>
The next major encounter in the show was the Battle of Cynwit, which occurred in 878. The battle in the series depicts the Danes besieging
the Wessex forces led by Odda the Elder. The Danish leader was Ubba, who was killed in the battle. The Danes had surrounded the Anglo-Saxon army on a hill and likely expected them to surrender, as they had little water, but the Wessex army attacked and were able to defeat Danish army. The Raven banner was taken by the Anglo-Saxon army and it was a major battle in which the Wessex king Alfred did not lead. In the series, the year of the battle is different and the credit for killing Ubba went to Uhtred. However, as shown in the series, it was an important battle for the Wessex kingdom and Odda was the likely leader of the Wessex during the battle. In effect, it is likely that the Anglo-Saxons were encamped on the hill during the real battle. Additionally, it is possible that Odda and his army were able to surprise the Danes with their resilience and win the battle.<ref>For more on the Battle of Cynwit, see: Jones, G. (2001). <i>A History of the Vikings</i> (2nd ed). London ; New York: Oxford University Press, pg. 238.</ref>
The Danes also attacked in January 878 the town of Chippenham, which is where Alfred held his court at the time. The series diverges from reality and has the Danes
attack Winchester instead. The show had already established the Winchester as the capital of Wessex and most likely sought to simplify the narrative instead of adding a new location for this battle. However, the attack did not occur there. The events, though, are generally accurate in that the Danes did attack in a surprising fashion at the height of winter, a period during when armies rested and did not launch invasions. Alfred was depicted as fleeing to the marshes of Somerset, barley escaping with his life , which was true and he did flee after the battle to hide from the Danes and reorganize his forces.<ref>For more on Alfred's flight to the marshes of Somerset, see: Swanton, M. (Ed.). (2003). <i>The Anglo-Saxon Chronicles</i> (New ed., paperback rev. ed., 5. impr). London: Phoenix Press.</ref>
The next major encounter was the Battle of Edington (Figure 2), which pitted Guthrum of the Danes against Alfred. The Danes had likely assumed Alfred to be significantly weakened after being forced to flee. The battle was characterized by Alfred summoning his fyrds, or the popular army from different parts of his kingdom, that gathered to fight the Danes. This allowed Alfred to create a greater force and demonstrated he retained the loyalty of his ealdormen despite his earlier losses. Egbert's stone was used as the meeting point for the fyrds in the series as well as in the chronicles describing the events. In effect, much of these events are true historically. The battle, unlike the series, involved an encounter of the armies where the Danes were driven into a fort and were besieged afterwards. In the series, the main battle is only depicted and
not the siege. In both cases, after Dane leader Guthrum was defeated and baptized, as a condition of the peace, and led his remaining army away. Eventually, the Danes formed another kingdom called Danelaw that represented areas where the Danes ruled for nearly another 100 years. For now, there was peace between Wessex and the Danes. The result was also the Danes were finally and decisively defeated, never to threaten Wessex seriously again.<ref>For more on the Battle of Edington, see: Hunter Blair, P. H., & Keynes, S. (2006). <i>An introduction to Anglo-Saxon Englan</i>d (3. ed., repr). Cambridge: Cambridge Univ. Press, pg. 111</ref> Arguably, this was the battle that may have prevented all of England falling to Danish hands in the 9th century.
