I have the discharge documents for Edward Trampleasure who was discharged from the Royal Veterans Batallion in 1806 aged 70 having served for 43 years. He was a Tavistock man and appears to have had his discharge in Plymouth by reason of 'old age - worn out'.
What duties would the old boy have had in the Army? He was a sergeant on retirement. I know there were French prisoners kept on hulks in Plymouth, but I doubt he would have been much good at stopping a mass break-out.
