@ TURBO_BIRD:
Might I recommend your reading up on the Battle of Stamford Bridge (25 September, 1066)?
King Harald Sigurdsson and jarl Tosti both were killed in the battle, as was Oeysteain Orri and nearly the entire Norwegian Army. The battlefield was WHITE with bleached bones 50 years after the battle.
Following the fight, Prince Olaf, who accompanied the Army but was guarding the Ships by his father's order, went to King Harold Godwinsson and begged for his father`s body.
King Harold gave the young man his father's body in return for a PLEDGE: Never again would Englishman and Norseman make war on one another.
The promise, from King Olaf Kyrre to King Harold Godwinsson, has been kept now for 948 years.
Thus ENDED the Viking Age.
BTW, much of the "Viking Age" raiding against England was STATE-SUPPORTED TERRORISM on the part of King Harald Bluetooth and his son, King Sven Forkbeard, the DANISH monarchs. It STOPPED, completely, when Knut Sveinsson became King of England. It had done its job. A major country had been kept in an expensive state of war-readiness for over 50 years...... at a cost to the aggressor of less than nothing.
It WORKED.
If WE are not careful, it will work AGAIN...... HERE.
