If your man stayed in the army long enough to get a pension then he would be termed a "Chelsea Pensioner" These records are now available on Findmypast.com - the English version of Scotlandspeople. I recently got copies - 6 full pages - of my 3g grandfather's army service records. He served from 1856 to 1875 in India - China - and Ireland. They give you all sorts of info. A real treasure. I was lucky enough to know his regiment. Worth a look. Cheers JOHN SHAW AUCKLAND NZ.
