Battle of Stamford Bridge - Wikipedia

On September 25, 1066, the Battle of Stamford Bridge took place. The English army under King Harold Godwinson defeat the invading Norwegians led by King Harald Hardrada and Harold's own brother Tostig, who were both killed in the fighting. From the article:

"According to Snorri Sturluson, before the battle a single man rode up alone to Harald Hardrada and Tostig. He gave no name, but spoke to Tostig, offering the return of his earldom if he would turn against Hardrada. Tostig asked what his brother Harold would be willing to give Hardrada for his trouble. The rider replied "Seven feet of English ground, as he is taller than other men." Then he rode back to the Saxon host. Hardrada was impressed by the rider's boldness, and asked Tostig who he was. Tostig replied that the rider was Harold Godwinson himself.[10] According to Henry of Huntingdon, Harold said "Six feet of ground or as much more as he needs, as he is taller than most men."

The exact location of the Stamford Bridge battlefield is not known. Local tradition places the battlefield east of the River Derwent and just southeast of the town in an area known as Battle Flats. The location of the Norwegian army at the start of the battle is not known for certain. Accounts of their location differ, depending on sources and interpretations. A common view is that the Norwegian army was divided in two; with some of their troops on the west side of the River Derwent and the bulk of their army on the east side. Another interpretation is that they were just leaving Stamford Bridge and moving along the old Roman road toward York (west side of the River Derwent).[11][unreliable source?]

The sudden appearance of the English army caught the Norwegians by surprise.[12] Their response was to deploy rapidly in a defensive circle.[citation needed] If the Norwegians were located at Battle Flats, there is no good explanation as to why they deployed into this formation. However, if they were located on the east side of the Derwent, the deployment made perfect sense. By the time the bulk of the English army had arrived, the Vikings on the west side were either slain or fleeing across the bridge. The English advance was then delayed by the need to pass through the choke-point presented by the bridge itself. The Anglo-Saxon Chronicle has it that a giant Norse axeman (possibly armed with a Dane Axe) blocked the narrow crossing and single-handedly held up the entire English army. The story is that this axeman cut down up to 40 Englishmen and was defeated only when an English soldier floated under the bridge in a half-barrel and thrust his spear through the planks in the bridge, mortally wounding the axeman.[13]

This delay had allowed the bulk of the Norse army to form a shieldwall to face the English attack. Harold's army poured across the bridge, forming a line just short of the Norse army, locked shields and charged. The battle went far beyond the bridge itself, and although it raged for hours, the Norse army's decision to leave their armour behind left them at a distinct disadvantage. Eventually, the Norse army began to fragment and fracture, allowing the English troops to force their way in and break up the Scandinavians' shield wall. Completely outflanked, and with Hardrada killed with an arrow to his windpipe and Tostig slain, the Norwegian army disintegrated and was virtually annihilated.[14]

In the later stages of the battle, the Norwegians were reinforced by troops who had been guarding the ships at Riccall, led by Eystein Orre, Hardrada's prospective son-in-law. Some of his men were said to have collapsed and died of exhaustion upon reaching the battlefield. The remainder were fully armed for battle. Their counter-attack, described in the Norwegian tradition as "Orre's Storm", briefly checked the English advance, but was soon overwhelmed and Orre was slain. The Norwegian army were routed. As given in the Chronicles, pursued by the English army, some of the fleeing Norsemen drowned whilst crossing rivers.[15]

So many died in an area so small that the field was said to have been still whitened with bleached bones 50 years after the battle."
