This portrait of Nick in full rig is a copy of the one which hangs in the Kincaid Gallery of The Rifleman's Museum in Winchester, and was painted in 1818 by Robert Lucius West, RHA. Nick was then aged thirty.
The Duke was C-in-C of the British forces during the Peninsula War (1807-1814) and commanded the allied forces at Waterloo. He was also Nick's fifth cousin. This portrait is by Sir Thomas Lawrence and hangs in Apsley House, London.
Nick was unusual in that he had been an officer in the Navy before becoming one in the Army (with the famous 95th Regiment - 'the Rifles'). He fought in the Peninsula and in North and South America, and was several times wounded. In later life, he was a Barrack Master in England and also overseas.
