Tuhia he whakamāramatanga mō tēnei wāhanga - I whānau a Thielmann ki Dresden. I uru atu ia ki te hoia eke hoiho o Saxon i te tau 1782, i kite ia i te mahi ki nga French i nga pakanga o Rhine
I mahi hoki ia i te taha o Prussia i te pakanga o Jena. Whai muri i te aitua o Jena, i tukuna a Thielmann e Saxony hei karere ki a Napoleon I, ka noho hei kaiwhaiwhai nui, a he nui tana mahi ki te kawe mai i te hononga Franco-Saxon. I haere tahi a Thielmann i te roopu Saxon i whawhai i te whakapae o Danzig me Friedland.
