Battle of Ringmere
The Battle site was located in lands under the control of Ulfcytel Snillingr, thegn of East Anglia, at a site once thought to be near Wretham, but now thought to be at Rymer in Suffolk. The Anglo-Saxon Chronicle reports that Ulfcytel Snillingr and the "councillors in East Anglia" attempted to buy a truce with Swein, but that the Danes broke the truce and marched to Thetford where a part of the East Anglian fyrd engaged them. The Danes managed to escape.
