 Many were then sold in the slave market in Istanbul; from June 1710, the Swedish ambassador Thomas Funck regularly visited the slave auctions in Istanbul to buy Swedish citizens, and Sven Agrell noted that they, among others, had bought a "carpenter's daughter" from Narva for §82, a "Captain's wife" for §240, Catharina Pereswetoff-Morath, eighteen years old, for §275 and a whole family, Anders Jonsson and his wife and children, though the funds were not always enough to buy all.The people bought free were probably taken to the camp of the king Charles XII of Sweden in Moldavia and returned to Sweden with him.In the peace treaty of 1721, the Russian czar allowed all prisoners in Russia to return home, except those who had converted to the Russian religion, as this was considered to make them Russian citizens; but as the Swedish slaves had been forced to convert to the orthodox faith by their masters, they were kept in Russia.
