The Conqueror in revenge burnt the town and laid waste the country between the Humber and Tees.
From this time onwards the Humber formed the boundary between the two kingdoms. In 684 we hear of the first English invasion of Ireland, but in the following year Ecgfrith was slain and his army totally destroyed by the Picts at a place called Nechtansmere (probably Dunnichen Moss in Forfarshire).
GRIMSBY, or Great Grimsby, a municipal, county and parliamentary borough of Lincolnshire, England; an important seaport near the mouth of the Humber on the south shore.
There are two large fish-docks, and, for general traffic, the Royal dock, communicating with the Humber through a tidal basin, the small Union dock, and the extensive Alexandra dock, together with graving docks, timber yards, a patent slip, &c. These docks have an area of about 104 acres, but were found insufficient for the growing traffic of the port, and in 1906 the construction of a large new dock, of about 40 acres' area and 30 to 35 ft.
Grimsby was an important seaport, but the haven became obstructed by sand and mud deposited by the Humber, and so the access of large vessels was prevented.
