Cnut arrived from Denmark in August 1015 at Sandwich in Kent with an invasion force of about 200 ships, but immediately went off plundering in Dorset, Wiltshire and Somerset. Eadric collected an army at Cosham, where king Æthelred lay sick. Edmund came to join him from the North, where his new territories lay. It is believed that Eadric had the intention of betraying Edmund, but when their forces came together he could not. The armies separated without incident, and Eadric soon took forty ships from the royal fleet, fled to Cnut, and entered into his service.
