Lennart Torstensson (17 August 1603 – 7 April 1651), Swedish Field Marshal and later Governor-General of Pomerania, Västergötland, Dalsland, Värmland and Halland.

[1] His parents were Märta Nilsdotter Posse and Torsten Lennartsson, of the noble house Forstena, who was supporter of King Sigismund and, for a while, the commandant of Älvsborg fortress.

His paternal uncle Anders Lennartsson was Lord High Constable of Sweden and trusted by Duke Charles, but he fell at the Battle of Kircholm in 1605.

[citation needed] At the age of fifteen he became one of the pages of the young King Gustavus Adolphus[1] and was allowed to observe the military campaign in Livonia.

He reached Korneuburg near the Habsburg capital in April but his exhausted army was unable to penetrate any further and lost 8,000 men in a failed siege of Brünn in Moravia from 3 May to 23 August.

On 23 December 1645, Torstensson, crippled by gout, was forced to resign his command to Carl Gustaf Wrangel and returned to Sweden in the early summer of 1646.

[1] Torstensson was remarkable for the extraordinary and incalculable rapidity of his movements, though very frequently he had to lead the army in a litter, as his bodily infirmities would not permit him to mount his horse.
