The Victual Brothers began as something almost respectable. In 1392, they were commissioned to break the Danish blockade of Stockholm by running supplies to the besieged city. The mission succeeded, but the pirates discovered that freelance raiding paid better than any commission. What started as wartime privateering metastasized into full-blown piracy across the Baltic and North Seas. From bases scattered along the Scandinavian and Finnish coasts, including Korsholm, they preyed on merchant shipping with impunity. Hanseatic traders, Danish vessels, anyone carrying cargo worth taking -- none were safe. The Victual Brothers operated less like a fleet and more like a loose network of opportunists, bound together by shared profit and mutual protection.

Among the captains who called Korsholm home, one name stands out: Otte von Peccatel. A nobleman turned pirate -- not an uncommon career trajectory in the medieval Baltic -- von Peccatel apparently ruled the castle until his death. The details of his tenure are sparse, filtered through centuries of fragmentary records, but the picture that emerges is of a man who used this remote Finnish outpost as a staging ground for raids deeper into Baltic shipping lanes. Korsholm's position on the Gulf of Bothnia made it ideal for this purpose. Ships heading north toward the lucrative fur and timber trades of Ostrobothnia had to pass within striking distance of the castle. Von Peccatel and his men could watch for sails from the shore and launch their attacks before merchants even realized the danger.

By the late eighteenth century, Korsholm Castle had been ruined for generations. New buildings rose on the old mound, their foundations grinding through whatever medieval remains still lingered in the soil. The castle was likely never built in stone -- wood was abundant and cheap in Ostrobothnia, and a garrison of pirates had little patience for the years-long labor of quarrying and masonry. A timber palisade, a ditch filled with brackish water, perhaps a watchtower or two: this was Korsholm at its height. It was the kind of fortification that served its purpose for a generation or two, then quietly surrendered to rot and rain. The mound itself, low and unremarkable, is the only physical trace that remains. Archaeologists have found little to excavate, since later construction disturbed the layers where artifacts might have survived.

Vaasa today is a modern Finnish city of broad streets and clean architecture, the regional capital of Ostrobothnia. The mound where Korsholm Castle once stood is easy to overlook -- a gentle rise in the terrain that could be mistaken for a landscaping feature. But for those who know its history, this unassuming spot connects Vaasa to an era when the Baltic was as wild and lawless as any frontier. The Victual Brothers were eventually suppressed in the early fifteenth century, hunted down by the Teutonic Knights and Hanseatic forces who had grown tired of losing cargo. Their bases were taken one by one. Korsholm, remote and already declining, simply faded away. No dramatic siege ended it, no fire reduced it to ash -- just the slow, patient work of time on wood.
