Henry Cadogan (British Army officer)

Lieutenant-Colonel Henry Cadogan (26 February 1780 – 21 June 1813) was a British Army officer who served and died during the Peninsular War (1807 – 1814).

Educated at Eton, on 9 August 1797 he became an ensign, by purchase, in the 18th Royal Irish Foot, which corps he joined at Gibraltar after its return from Tuscany, and obtained his lieutenancy therein in 1798.

When the 71st Highlanders, then recently transformed into a light infantry corps, arrived out in Portugal in the summer of 1810, Cadogan joined it at Mafra and assumed command in succession to Colonel Peacocke.

At its head he distinguished himself on various occasions during the subsequent campaigns, particularly at Fuentes de Oñoro, 5 May 1811, when he succeeded to the command of a brigade consisting of the 24th, 71st, and 79th regiments, at Arroyo dos Molinos 28 Oct. 1811, and at Vittoria, 21 June 1813, where he fell.

On 13 July 1813, a motion proposed by the then Foreign Secretary, Lord Castlereagh was passed in the House of Commons for a monument to be erected to Cadogan in St Paul's Cathedral.
