He was the son of Torsten Svensson (Stålhandske [sv]), a noble military officer of Swedish ancestry from West Gothland, and Carin Lydiksdotter Jägerhorn, of Finnish nobility from southern Finland.
Torsten's father died in the Battle of Stångå when he was four years old, and his mother married a Scottish soldier, Major Robert Guthrie.
[2] In 1629 he was promoted to lieutenant-colonel in the Nyland and Tavastehus Cavalry regiment, leading Finnish horsemen, also known as Hakkapeliitat, for the first time into the Thirty Years' War.
Similarly, he distinguished himself at the Battle of Chemnitz as well as in Silesia, where he defended his positions during the whole year of 1640 against Count Mansfeld.
In 1644 he crushed a hostile army corps in the Jutland, but then fell ill and died in Haderslev on 21 April 1644.
