The Vikings’ unfortunate victims came to believe that no one could get rid of them and to begin with, they were right. But in 871 a warrior named Alfred and his brother, Aethelred, King of Wessex, decisively defeated a Danish invasion at the Battle of Ashdown, in Berkshire. Aethelred died shortly after and Alfred succeeded to the crown. He was well aware that the Danes were determined to destroy Wessex and in 878 the Danes were back in force under their king, Guthrum.
Most modern Britons remember Alfred as the king who burned his hostess’s cakes. Yet he was the only English king ever to have been called ‘the Great’. He was a scholar and a law giver, a good administrator, an astute soldier, and the man who gave England a navy capable of tackling the Danes at sea. Maybe we shouldn’t be surprised that he never devoted much time to cookery! After Ashdown, things went very badly for Alfred. The Danes forced him into hiding (where he burned the cakes), but he ran an effective guerrilla campaign gathering his strength all the time, and then fell on the Danes at Edington (in Wiltshire), inflicting so convincing a defeat that Guthrum asked for terms and promised to leave Wessex alone. Alfred didn’t trust the Danes and continued to build up his navy. He also established an early warning system based on beacons and set up local militias known as the fyrd that could be assembled quickly in an emergency.
In 886, following renewed Danish raids, Alfred drove the Danes out of London and gained territory north of the Thames. In 893 the Danes raided again, this time hoping to split Alfred’s forces with a seaborne landing on the south coast and an invasion from the north. The Saxons quickly blockaded the first landing, although some of the Danes managed to escape. Alfred and his son Edward the Elder defeated both invasion forces in fighting that ranged across southern and western England. Their grand plan may have been in tatters, but the Danes were unwilling to give up. In 895 they sailed up the river Lea, a tributary of the Thames east of London, in large numbers. Alfred responded by building two forts at the mouth of the river, which he blocked with a heavy boom.
Trapped, the Danes had to abandon their ships and scuttle back to the Danelaw on foot. In Alfred’s reign, the Saxons probably adopted some of the Danes’ methods of warfare, including fighting with axes from behind interlocked shields. Alfred died in 899, but Edward, his son and successor, continued his work. In 903, having repulsed a fresh Danish raid, Edward advanced deep into the Danelaw itself, inflicting one defeat after another. For years an almost permanent state of war existed, with the Saxons steadily gaining the upper hand.
Edward’s son Aethelstan did even better than his father. He recovered Mercia, threw the Danes out of York (their principal stronghold in the north), reconquered Northumbria, and campaigned successfully in Scotland and Wales, receiving the homage of their rulers. In 937 the resentful King Constantine III of Scotland attempted to halt Aethelstan’s runaway progress, but his army took a fearful hiding at the Battle of Brunanburgh
