Those who escaped fled across the Thames and took refuge on an island in the Colne.

The Saxons besieged them there; but when the Danes were about to surrender from want of provisions the news arrived that the Northmen of Northumbria and East Anglia, with 240 ships, had landed suddenly in Devonshire, and had laid siege to Exeter.
The siege of the island was at once raised, and King Alfred marched against the new arrivals, and advancing with great speed fell upon them and defeated them.

Then hastily returning he came to London and, joined by a strong force from Mercia, marched against Milton, where Hasting had been joined by the great number of the Danes who had formed the army in the Weald.

Hasting himself was away, but his army marched out to meet the Saxons.
A great battle was fought, but the Danes could not resist the ardour of their assailants.

Their army was routed and their fortress stormed.
