Standalone short: Lars Gathenhielm, the illiterate privateer king of Gothenburg, and the fortress that shielded his pirate fleet. Leif + Margareta.
He could not read or write a single word. And yet, blessed by the king himself, he became the pirate king of the west coast. Meet Lars Gathenhielm — to everyone, simply Lasse i Gatan.
Sailing under the king's warrant from Gothenburg, in eight years he owned or armed some fifty ships and seized more than eighty enemy vessels. The king made him a nobleman for it. And when he died, his widow Ingela ran the whole pirate empire herself.
And every prize ship had to slip past one thing to reach the lair: the guns of Älvsborg. The fortress was the shield over the whole wasps' nest. Lasse himself took his name from this farm in Onsala — Gatan — the boy who would die rich, ennobled, and feared the length of the Kattegat.
That enemy was Peter Wessel Tordenskjold — who came to choke the Gothenburg raiders at their source. The pirates of Lasse i Gatan are the reason the great sea-duels of 1717 and 1719 were fought right here, under Älvsborg's walls.
