Surgeon Thomas Fiddes entered the Army Medical Department as a hospital mate in 1808. He served throughout the Peninsular Campaign (1808–1814) in Portugal as a hospital assistant under Sir John Moore and Sir John Craddock and in Spain and France as an assistant surgeon under the Duke of Wellington.
In Portugal, Surgeon Fiddes served at: Obidos (15 August 1808), Rolica (17 August 1808), Vimeiro (21 August 1808), in the advance on Oporto (10–11 May 1809) and in the capture of Oporto (12 May 1809). He was wounded in the retreat to Corunna, receiving a deep flesh wound through the left shoulder.
In Spain, he took part in the operations against Ciudad Rodrigo (9 January 1812), the Siege of Badajoz (7 April 1812), Salamanca (22 July 1812), Burgos (21 Oct 1812), Tordesillas (October 1812), Vitoria (21 June 1813), San Sebastian (25 July 1813), Bidassoa (7 October 1813) and the investment of Bayonne (14 April 1814). He was wounded at Salamanca where he received a slight flesh wound to his left hand. At Vitoria he sustained a severe contusion in the left eye by the passage of a cannon ball which left him with slightly impaired vision. He was granted a pension for his wounds.
Surgeon Fiddes was thanked by Major General Hay Commanding the 5th Division, the Inspector General of Hospitals and the officer commanding the 2nd/47th Regiment for re-establishing the health of that corps while in winter quarters following the retreat from Burgos.
