Battle of Derby
July 917 battle
In July 917, Æthelflæd 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. Æthelflæd took advantage of the weakened burh and successfully assaulted the town in July 917; the whole region subsequently being annexed into English Mercia.
