[5][1] During the gathering, the Bornholmers braggingly brought Printzensköld to write about them:[The island] is endowed with an exceptionally good and fertile soil, such that it has been regarded as the finest land, both by its own inhabitants and by others, that has belonged to the Kingdom of Denmark.

[16] However, at the beginning of November, the Swedish government imposed an extraordinary tax on the peasantry, in which each land-owning peasant was to pay 16 riksdaler in silver coin.

Nonetheless, the drainage of Bornholm's resources brought Printzensköld to plee Charles X Gustav to spare the island from further levies:[19][18] I could by no means have imagined that the island would be so devoid of resources and money as it is, and I doubt that the common people can pay the first installment in cash, but only in goods.On 7 August 1658, Charles X Gustav landed in Korsør to eliminate the remnants of the Danish state.

[1] King Frederick III encouraged the Bornholmers to liberate themselves and urged them to destroy the Swedish garrison on Hammershus, which caused the conspiracy to spread among the inhabitants.

[20][21] According to M. K. Zarhtmann, the conspiracy's leader was Poul Hansen Ancher, who was a priest in Hasle and Rutsker Parish and deeply popular in Bornholm.

In addition to having connections to citizens in Rønne and Priests throughout the Island, members of the conspiracy included Peder Olsen, Villum Clausen, and Niels Gumløse.

[24] Until then, external threats remained Printzensköld's main priority, while internal unrest, like the ongoing Danish-minded conspiracy, seemed, by the start of November, unthinkable for him.

The Borringholms Manifest, a manifesto published right after Printzensköld's death to defend the Bornholmers' actions, and a Swedish witness both agree that Printzenslöld was captured.

[32] After the conspirators had captured the Swedes, they rode up to Jakob Tresløv in Nyker and sent word to the villages of Vestermarie and Klemensker to send armed commoners to Ruth's Church in Rutsker.

[37] During the night between 8 and 9 December, the rest of the rebel forces reached Hammershus led by Captain Niels Gumløse and accompanied by Peder Olsen and Poul Ancher.

[38][39] According to the aforementioned Swedish witness, Rønne's captain, Claus Kam, wore Printzensköld's clothes and rode on his horse outside the fortress to intimidate the Swedes.

[40][39] Per Lagman met with the leaders of the rebellion to write an instrument of surrender,[35] and soon after the Swedish garrison left their weapons and became prisoners of war.

In the King's letter of takeover, the Bornholmers were promised: "such privileges and concessions, both regarding conscription, taxes, and in other ways that could seek the best and prosperity of the land."

With this assurance, Olsen returned to Bornholm, and in early January 1659, 160 Danish troops arrived at Hammershus under the command of Colonel Mikael Eckstein, who took over the island's administration.

With the only knowledge that Bornholm had revolted, Charles X Gustav sent a letter to Printzensköld on 5 January, allowing him to transfer all the troops he needed from Pomerania to the island.

Paul Ancher got patronage to Aa Church, Peder Olsen, who had been accused of treason in 1645, was appointed as judge on the island, and Jens Kofoed got pardoned for previous crimes.

Villum Clausen, who shot Printzensköld, and Hans Lavridsen both received farm estates for life, while Peder Jensen became ridefoged (bailiff).

[48] At the conclusion of peace in Copenhagen, on 27 May 1660,[32] it was decided that Bornholm would remain under Denmark in exchange for compensation to the Swedish crown in Scanian estates.

During Hannibal Sehested's subsequent negotiations in Stockholm, the amount of compensation was set to 8,500 thalers of land value, securing Bornholm's allegiance to Denmark.

Additionally the then-prime minister of Denmark, Anders Fogh Rasmussen, held a speech praising the Bornholmers' resistance and thanking the revolt's leaders.
