in mainland Europe precarious, they crossed to England in 330 ships in two divisions. They entrenched themselves, the larger body at Appledore, Kent, and the lesser under Hastein, at Milton, also in Kent. The invaders brought their wives and children with them, indicating a meaningful attempt at conquest and colonisation. Alfred, in 893 or 894, took up a position from which he could observe both forces. While he was in talks with Hastein, the Danes at Appledore broke out and struck north-westwards. They were overtaken by Alfred's eldest son, Edward and were defeated at the Battle of Farnham in Surrey. They took refuge on an island at Thorney, on the River Colne between Buckinghamshire and Middlesex, where they were blockaded and forced to give hostages and promise to leave Wessex. They then went to Essex and after suffering another defeat at Benfleet, joined with Hastein's force at Shoebury. Alfred had been on his way to relieve his son at Thorney when he heard that the Northumbrian and East Anglian Danes were besieging Exeter and an unnamed stronghold on the North Devon shore. Alfred at once hurried westward and raised the Siege of Exeter. The fate of the other place is not recorded. The force under Hastein set out to march up the Thames Valley, possibly with the idea of assisting their friends in the west. They were met by a large force under the three great ealdormen of Mercia, Wiltshire and Somerset and forced to head off to the north-west, being finally overtaken and blockaded at Buttington. (Some identify this with Buttington Tump at the mouth of the River Wye, others with Buttington near Welshpool.) An attempt to break through the English lines failed. Those who escaped retreated to Shoebury. After collecting reinforcements, they made a sudden dash across England and occupied the ruined Roman walls of Chester. The English did not attempt a winter blockade but contented themselves with destroying all the supplies in the district. Early in 894 or 895 lack of food obliged the Danes to retire once more to Essex. At the end of the year, the Danes drew their ships up the River Thames and the River Lea and fortified themselves north of London. A frontal attack on the Danish lines failed but later in the year, Alfred saw a means of obstructing the river to prevent the egress of the Danish ships. The Danes
