I recently bought Heikki Pihlajamäki's new book Conquest and the Law in Swedish Livonia. On page 135 he speaks of a "mystery" which was quite unknown to me. Apparently there has been some confusion as to what happened with regard to the Court once war broke out in February. Margus Laidre has apparently claimed that it relocated to Reval under armed escort, while Heinz von zur Mühlen stated that it went to Riga. Pihjalamäki mentions that the letters from the High Court clearly shows that it from January 1703 had its seat in Riga.
The correspondence of the Governor General of Livonia is able to clear up a few things. On 9 March 1700 Charles XII wrote to Colonel Skytte in Dorpat (a letter which is missing in Riksregistraturet), telling him to bring the archive of the Court to safety in Pernau or Reval if the military situation started to appear dangerous. Some time later the Court itself had turned to the King for help and on 10 April he sent a new letter to Skytte (not in Riksregistraturet, but a copy is preserved in LVVA, Fond 7349, op. 1, vol. 288). Charles ordered Skytte to start moving the archive immediately.
Skytte got this letter about a month later and quickly informed Governor General Dahlbergh. All preparations had been made, he reported, but as the latest news from Riga was encouraging it seemed unnecessary to go through with the transfer. Was it really worth the cost, especially as the Court had changed its mind about relocating?
Dahlbergh tentatively agreed to postpone, but wrote the Court to confirm the change of heart. He noted that the fortunes of war could shift again, but he was quite happy to disregard the King's instructions if the Court did not want to move.
And so it stayed.
