ON a side note, Canute, or C'nut declared his capital at Gainsborough in Lincolnshire, which sits on a tidal section of the River Trent, giving him access to the sea by boat. Gainsborough today itself is a small run down backwater market town, which enjoyed a brief burst of prosperity after WW2. The section of the Trent it sits on is tidal, and its thought this is where Canute tried to turn the tide back.
