I am researching about the general Friedrich Wilhelm von Buxhoeveden (https://en.wikipedia.org/wiki/Friedrich_Wilhelm_von_Buxhoeveden)
Firstly, I wonder what was his main motivation for participating in a war with the Swedish Empire in 1808, it seems strange why he would fight on the Russian side since the same empire had just few decades back annexed by force the land himself was brought up in. What did he think about the future Russification attempts of Finland? Did he support it or did he just join the war as he saw he was best fit to limit the causalities in an inevitable war? Please give some input and thoughts.
Secondly, I wonder if anyone know of any book/text/article that talks about him more in detail? All I can find are encyclopedias with facts and timelines about his positions.
