Norman Conquest of England - Tostig's Raids and The Norwegian Invasion

Tostig's Raids and The Norwegian Invasion

In early 1066, Harold's exiled brother Tostig Godwinson raided southeastern England with a fleet he had recruited in Flanders, later joined by other ships from Orkney. Threatened by Harold's fleet, Tostig moved north and raided in East Anglia and Lincolnshire, but he was driven back to his ships by the brothers Edwin, Earl of Mercia, and Morcar, Earl of Northumbria. Deserted by most of his followers, he withdrew to Scotland, where he spent the summer recruiting fresh forces. King Harald III of Norway invaded northern England in early September, leading a fleet of over 300 ships carrying perhaps 15,000 men. Harald's army was further augmented by the forces of Tostig, who threw his support behind the Norwegian king's bid for the throne. Advancing on York, the Norwegians occupied the city after defeating a northern English army under Edwin and Morcar on 20 September at the Battle of Fulford.

Harold had spent the summer on the south coast with a large army and fleet waiting for William to invade, but the bulk of his forces were militia that needed to harvest their crops, so on 8 September Harold dismissed them. Learning of the Norwegian invasion, he rushed north, gathering forces as he went, and took the Norwegians by surprise, defeating them at the Battle of Stamford Bridge on 25 September. Harald of Norway and Tostig were killed, and the Norwegians suffered such horrific losses that only 24 of the original 300 ships were required to carry away the survivors. The English victory came at great cost, however, as Harold's army was left in a battered and weakened state.
