In the autumn the besieged army left Chester, marched down to the south of Wales and devastated the Welsh kingdoms of Brycheiniog, Gwent and Glywysing until the summer of 894. They return via Northumbria, the Danish held midlands of the Five Burghs, and East Anglia to return to the fort at Mersea Island. In the autumn of 894, the army towed their ships up the Thames to a new fort on the River Lea. In the summer of 895 Alfred arrived with the West Saxon army, and obstructed the course of the Lea with a fort either side of the river. The Danes abandoned their camp, returned their women to East Anglia and made another great march across the Midlands to a site on the Severn (where Bridgnorth now stands), followed all the way by hostile forces. There they stayed until the spring of 896 when the army finally dispersed into East Anglia, Northumbria and according to the "Anglo-Saxon Chronicle", those that were penniless found themselves ships and went south across the sea to the Seine.
