The news about the meeting at Jurburg reached Riga in early April. On the 9th Governor General Dahlbergh wrote to Major General Horn in Narva, telling him that the meeting had been followed by an advance by the Swedish army, apparently towards Warsaw. Dahlbergh prayed that the enterprise would end well, noting that it had been reported from Poland that Great Crown Hetman Jabłonowski had died - "we have lost a man of good intentions."
Two days earlier Dahlbergh had informed the Chancery in Stockholm. Jabłonowski had, he said, on a number of occasions made considerable efforts for the common good.
