When going through the Bienemann catalogue (1908) one of the surprising discoveries is the scarcity of correspondence from Swedish diplomats in Poland during the years leading up to the GNW. From the preserved letter books it's obvious that Dahlbergh did correspond with both Cuypercrona in Danzig and Wachschlager in Warsaw, but almost no letter older than 1700 seem to remain in the archive of the Governor General (LVVA, fond 7349 & EAA 278). During a recent visit to Riksarkivet I discovered the reason for this - they were removed by the historian Carl Schirren long before Bienemann and others started to catalogue the archive. Carl Schirrens huge collection of copies and excerpts (194 volumes) were transferred to Sweden in the early 1920's and a couple of years earlier a smaller portion of originals (15 volumes) had preceded it. Volume 4 contains the missing diplomatic reports and volume 13 various maps and plans, for example one which shows the siege of Kokenhusen in 1700 and another which shows the Saxon positions along the Daugava. The volume also contains two lists of travellers passing the border post Neuhausen going from or to Russia (1698 and January-June 1699). The latter was used by Fred Otten for his work Der Reisebericht eines anonymen Russen...(1985).
