“ From 1648 to 1651 he ruled all the western provinces of Sweden, as governor-general. On his death at Stockholm (April 7, 1651) he was buried solemnly in the Riddarholmskyrka, the Pantheon of Sweden. 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. He was also the most scientific artillery officer and the best and most successful engineer in the Swedish army. ”
