Wachtmeister was born into an aristocratic Swedish family in 1757 and embarked on military life at a young age, receiving a
commission as an
ensign in 1772. In 1778 he went abroad to gain experience on campaign, joining the
Prussian Army fighting
Austria in the
War of the Bavarian Succession from 1778 to 1779. Returning to Sweden, by 1780 Wachtmeister had a posting as a
lieutenant-colonel commanding a battalion in the provincial
Dalarna Regiment. He went on to fight against Russia at the
Battle of Valkeala and in numerous others until the war ended in 1790 without any real gain for either country. His later battles were mainly fought against
Napoleon in
Pomerania and against Russia who in 1809 invaded Sweden after
a military coup overthrew the current King
Gustav IV. The new King
Charles XIII ordered Wachtmeister to attack the Russians behind enemy lines which he did at the
battles of Sävar and
Ratan. ==Personal life==
