What treaty has a document not specifically linked to Wedmore that is a Treaty of Alfred and Guthrum, that was the result of an army of the Anglo-Saxon kingdom of Wessex under Alfred the Great defeating the Great Heathen Army?
Battle of Edington At the Battle of Edington an army of the Anglo-Saxon kingdom of Wessex under Alfred the Great defeated the Great Heathen Army led by Guthrum on a date between 6 and 12 May AD 878, soon resulting in the Treaty of Wedmore later the same year. The primary sources locate the battle at ""Ethandun"" or ""Ethandune"", and until a scholarly consensus identified its location with the present-day Edington in Wiltshire it was known as the Battle of "Ethandun", a name which continues to be used.
Battle of Derby In July 917, Aethelflaed launched her first offensive foray and selected the fortress at Derby as her target. At that time the local ruler had probably joined with the armies from Northampton and Leicester in a number of raids to attack Mercia. Aethelfled took advantage of the weakened burh, and successfully assaulted the town in July 917; the whole region subsequently being annexed into English Mercia.
