Nice find
Vikings feared Finns and avoided coming even near Finland after a raid 950 years ago that failed completely.
Back then a massive Viking Army tried to invade Tavastia, but Finns from small villages shattered their war troops.
The Vikings sailed on Kokemäenjoki river to Nokia. Their navy fleet consisted of 200 ships and nearly 2000 men. Their attack was very organized since their intention was to submit Tavastians and collect an annual tax from them.
Tavastians refused to bend and they were able to resist the Vikings - who were feared by half of the world - so that those Vikings who survived fled to the Gulf of Finland.
Deputy commander Egil was killed in Pälkäne and commander Freygeir in Saarenmaa. Most of the ships were destroyed. It was their last attack due to their defeat.
Freygeir was leading his dragon ship with 40-50 men. Egil had a ship with 20-30 rowing men.
Brusi, the third commander, had a smaller dragon ship. They had some men from Denmark and from Ahvenanmaa.
The target was Nokia where sable fur was sold and where a big storage of fur located. Sables were expensive back then, with one sable fur you could buy a big farm with a horse.
The ships arrived during night and the furs were taken to the ships afterwhich they sailed away. Tavastians couldn't do a thing.
Then Freygeir divided his group into two groups and ordered Egil and Brusin to sail to Pälkäne.
Freygeir sailed to Lusi with the intention to fool the Tavastians by making a false attack. His intention was to meet up with Egil's troops in Hyöme where they would plunder Tourunmäki's fur-storage together.
Vikings knew all the water routes, places and villages in Tavastia from their previous peaceful trading journeys.
Tavastia had only 20.000 inhabitants and no village could come up with even 50 men able to fight.
Vikings again were well armed, while Tavastians had only some spears and swords. Everyone had a bow and arrow but they didn't help much.
Kyllönkoski's riverbed was narrow, so Finns from nearby felled trees to block it, hid sharpened spears under the water and pulled ropes across the river.
The Vikings knew that they would get arrows and spears from the shores and had to go through fast.
Commander Egil lost it completely when the ships got stuck in the obstacles and when he jumped in the water he was killed by a spear.
There were about 1000 Vikings in the river and 50 Tavastians on the shores. They threw glowing firewood on the ships which caught fire. The Vikings got through Kyllönkoski late in the evening, although they were meant to meet Freyger's men in Hyömäki at noon.
Since there was no sign of the men Brusi decided to go home. They went to Pyhäjärvi from where they would get through Kopsjoki to Suolijärvi.
But the smiths in Kettula put a strong iron chain across Kopsjoki and Brusi couldn't get past it.
Brusi was in rage and he abandoned his dragon ship. He went to one of the smaller ships (or boats) and ordered the other ships to follow him and look for another route to Suolijärvi. When he was at Laurinkallio the Finns from Tuulos attacked.
Brusi's ships were bagged in Haaksivalkama where Finns from Tavastia attacked once again. The battle was fierce. The Vikings made it to Suolijärvi, but there are more spearheads, swords and bones in Tavastia than anywhere else.
A few ships managed to get through the iron chain. Finns from Alvettula attacked Freygeir and he had to turn back emptyhanded.
In Hiidenjoki the Tavastians were in ambush and killed Freygeir.
Brusi was the only war lord who made it home alive.
All and all only 10 % of the Vikings stayed alive. Finns riding horses on the shores 'escorted' them out from Finland. Vikings were certain that Finns possess magical powers, so if a Viking ship came too close later on Finnish women stood on the shores 'casting spells' upon them and they turned around quickly
Finland has villages called "Murder island", "War meadow" and "Jawbones of hundred men", they are obviously related to the places where the battles took place.
In light of this it's no wonder that Finns slaughtered one million Russians in the Winter War - alone! Tanks or ships, doesn't matter, lol
