The large age-gap between the couple is notable - 1812/1831
Looking at the wiki for the 23rd line regiment, it looks like they took part in the conquest of Algeria from 1830-1857 - he could actually have been in Algeria from the moment of his entering service. The conquest culminated in the capture of resistance leader Lalla Fatma N'Soumer in 1857. She seems to have been a Boudicea-like character. She was captured in July, which means this can't be reason for the award, but perhaps Theophile had previously conducted himself well in other Algerian campaigns.
Whatever the truth is, it does feel like the plot of a dramatic novel is starting to take shape! I really do hope they have descendants.
