I did some digging on Ancestry, and found him listed as 703 Troop Sgt Major, Boucher, Chas Henry, in the Crimea Medal rolls for the Carabiniers. As stated previously, his discharge papers are available on Find My Past, with his medical report being very interesting. It states, that on the 24th September 1862 he fell from his horse while participating in a field exercise at Aldershot, fracturing his arm, and having a squadron of cavalry riding over him. The fracture resulted in a permanent deformity of his arm, making him unfit for further service, or, for being able to earn a living as a Laborer. This document is dated 1863.
His conduct is listed as Very Good, his name was never entered into the Defaulters Book, and he was never tried by a Court Martial. His service for the Crimea and India is also mentioned along with his LSGC medal. He was credited for service of 24 years 53 days.
That's quite a story, thanks for posting this as I enjoyed looking him up, took a little bit though, had to use some other soldiers names to pull up the roster for the Crimea and found him with his name slightly misspelled.
Any chance for a photo of his medals being posted here?
