Torrens entered the Royal Marines in 1796. He achieved renown in 1811 by overseeing the defence of the
Baltic island of
Anholt against superior Danish forces in the
Walcheren Expedition, during which he was severely wounded and was awarded the title of
brevet major for his bravery. On the 200th anniversary of the battle of Anholt, the sword presented to Torrens was purchased by the
Royal Marines Museum. After divesting the island in August 1812, the garrison was redeployed to Northern Spain in the winter of 1812 with Major
James Malcolm, alongside Spanish forces. Torrens returned to London on 31 August, however, and was ordered to report to Woolwich Divisional Headquarters. Although the
Dictionary of National Biography (1885-1900) makes reference to his being "appointed Colonel of a Spanish Legion", this claim has yet to be substantiated by other sources. There is a letter dated 16 January 1813, co-signed by Torrens and
Edward Nicolls, requesting that Torrens not be seconded to the Spanish army, but that Nicolls should take his place. The outcome is unclear, but it appears that a Capt. Baillie went instead. Torrens was subsequently appointed the officer commanding the Marines on
HMS Blenheim, and performed this duty from 23 June 1813 to 11 January 1814. His final deployment was off the
Low Countries during the winter of 1813–1814, at the siege of
Antwerp. He was back in
Portsmouth in March 1814.
Confusion about rank According to
DNB, Torrens was promoted to the rank of
Lieutenant-Colonel in 1819, and to that of
Colonel in 1837; however, he had retired on half-pay in 1835. He is referred to as "Colonel Torrens" in
Hansard from November 1826 to August 1832, and in the report of the 1831
parliamentary select committee on
steam carriages, on which he sat (published in 1834). He is similarly named in an 1832 piece in ''
Cobbett's Political Register'', opposing his policies. The
DNB entry for his son, Sir Robert Richard Torrens, refers to the elder Torrens as "Lieutenant-Colonel". ==Economist==
