  • January 4 – Battle of Reading: A West Saxon force, under the command of King Æthelred I and his brother Alfred, is defeated by the Danes at Reading. Among the many dead on both sides is Æthelwulf. The Saxon troops are forced to retreat, allowing the Vikings to continue their advance into Wessex.^[1]
  • January 8 – Battle of Ashdown: The West Saxons, led by Æthelred I and Alfred, gather at the Berkshire Downs. The Danes under the command of Halfdan and Bagsecg occupy the high ground, but are successfully attacked by Alfred's men. During the battle Alfred breaches the shield wall formation.^[2]
  • January 22 – Battle of Basing: The West Saxon army, under the command of Æthelred I, is defeated at Basing. The Danes, led by Halfdan, are victorious; Æthelred is forced to flee and regroup, leaving behind precious winter supplies.^[3]
