An invasion occurs on the very day of the coronation

Ecgberht ascends the throne of Wessex in 802 after the death of Beorhtric. On the very day of his accession, his kingdom is invaded by the ealdorman Æthelmund at the head of troops from the Worcester region. The men of Wiltshire repel the attack at Kempsford, but both leaders of the enemy armies perish during the battle.
