The "Anglo-Saxon Chronicle" for 878 has a similar description to Asser. It details Alfred's movements before, during and after the Battle of Edington. It describes Guthrum's surrender, his baptism at Wedmore, and the twelve days of celebration. The only reference to an accord at Wedmore is that from Asser's "Life of Alfred". If there was a formal treaty, contemporary with the events at Wedmore in 878, no such document still exists. A truce was made; and at a later date a formal treaty was agreed. This one was known as the Treaty of Alfred and Guthrum and it defines the boundaries between Alfred and Guthrums territories as well as agreements on peaceful trade, and the weregild value of its people. This document still survives
