 By this treaty, all of England except Wessex would be controlled by Canute and when one of the kings should die the other would take all of England, that king's son being the heir to the throne.After Edmund's death on 30 November, Canute built a church, chapel, or holy site after winning the battle to commemorate the soldiers who died in battle.A few years later in 1020 the completion of the memorial church known as Ashingdon Minster took place, on the hill next to the presumed site of the battle in Ashingdon.
