This first attack may have taken place at Harwich, and the area around was possibly held by the Danish army for their winter stronghold, both for ships and men.The name Harwich itself could derive from Here Wic, or Army Port.The Chronicle reads as if the Danes had already taken Thetford, intending to settle there for the Winter, when they were attacked by King Edmund, and his Anglo-Saxon fyrd, or army, in late November.If King Edmund had indeed paid off the Danes to avoid war in 865, we do not know why the same thing was not attempted in 869.Ragnar Lothbrok or Lodbrok, (Leather Britches), was the most famous viking of his day. One was called Ubba, and the other was known as Ivar the Boneless."Boneless" probably refers to the snake, a creature thought to be full of cunning and fearless in battle.
The chronicle implies that King Edmund now paid them off in money, horses and supplies to keep the peace in East Anglia, and prevent further destruction.
It was the year of full scale invasion by the Great Army of the Danes.
The year began with a Danish army having over-wintered at Thanet.
Perhaps the Danes now felt strong enough to take him on, or perhaps he had now resolved to resist them.
He may have been given no choice, for as we have seen in Kent in 865, one band of Vikings would happily take your money, and then another band might attack you anyway.
