I have finally started updating the FAQ page - not MHM's clear, excellent original questions and answers, but the list of regiments which served in the Crimea had become out of date after changes to the British Army in the last few years. The opportunity has been taken to include links to the Wikipedia page for each regiment (in the continued sad absence of regiments.org) and to the MOD page for the modern incarnation. The intention is to also include links to the relevant pages in Hart's Army List for January 1855 at Google Books.
So far the Cavalry Division has been updated, but without the Google Books link. All the rest will follow in the next few days.
