Knut Posse

Knut Posse was appointed bailiff of Stockholm Castle in 1466 and in 1472 was bailiff at Hämeenlinna Castle. In 1490 he was appointed courtier at Kastelholm Castle and in 1495 Posse was governor of Viipuri castle. He lived until 1500 and died at Kastelholm Castle. He was buried at Turku Cathedral.

In 1471, Regent Sten Sture ordered Posse to load the garrison of Stockholm Castle onto boats to ready a surprise attack on the Danish and German Army of King Christian I of Denmark. His order were to attack the Danes in the rear from Stadsholmen, . The Danes would then be attacked on three sides: Sten Sture would attack from the south, Nils Sture would flank the Danes and attack from the rear, and Posse would attack the Danes from the east flank. The Danish were completely surprised by Posse's attack. Soon after the battle started, Christian I sent more troops to reinforce their position near Sankta Klara kloster. The Danish Armies were no match for Posse's men, whom he led from the front. Posse's legs were hit by several Danish arrows. [2]

From 1495 to 1497, Posse was governor of Viipuri castle. Posse defended it against a Russian onslaught in 1495 . He saved the castle against a bigger Russian force with what became known as 'the Viipuri blast'. For this, Posse became immortal in Finnish and Scandinavian folklore.[3]
