Thereafter the king sailed to the Humber, and up along the river, and
then he landed. Up in Jorvik were two earls, Earl Morukare, and his
brother, Earl Valthiof, and they had an immense army. While the army
of the earls was coming down from the upper part of the country, King
Harald lay in the Usa. King Harald now went on the land, and drew up his
men. The one arm of this line stood at the outer edge of the river, the
other turned up towards the land along a ditch; and there was also a
morass, deep, broad, and full of water. The earls let their army proceed
slowly down along the river, with all their troops in line. The king's
banner was next the river, where the line was thickest. It was thinnest
at the ditch, where also the weakest of the men were. When the earls
advanced downwards along the ditch, the arm of the Northmen's line which
was at the ditch gave way; and the Englishmen followed, thinking the
Northmen would fly. The banner of Earl Morukare advanced then bravely.
