1775–1845
A Swedish military officer from a prominent noble family, he is remembered both for his service and for writing about the Finnish War of 1808–1809. His life links Finland and Sweden at a turbulent moment in Nordic history.
Born in 1775 at Kiala in Nyland, Finland, Gustaf Magnus Adlercreutz was a Swedish officer and a member of the Adlercreutz noble family. Swedish-language reference sources identify him as the son of Tomas Adlercreutz and Hedvig Catharina Barthéels, and as the brother of the better-known general Carl Johan Adlercreutz.
He lived through the era of the Finnish War and is also connected with written reflections on that conflict. Project Runeberg lists him as the author of Anmärkningar och nödvändiga upplysningar vid Herr C. J. Holms Anteckningar öfver fälttågen emot Ryssland åren 1808 och 1809, showing that he left a printed record linked to one of the defining military struggles of his time.
Adlercreutz died in 1845 at Läckö in Västergötland, Sweden. Although he is less widely known today than some of his relatives, his career and writings place him within the military and historical world of Sweden and Finland in the early nineteenth century.
