Perhaps allso those are a yet unidentified, allthough I would have thought their company C.O would have reported them as missing. A war zone is not the place to go AWOL. May have happened tho'. I have a couple missing at sea- must check their last know addresses.
Hmm just pondering as you do. It won't explain some of Bay Horses anomalies but I wonder whether some of the missing ones were not at addresses that exist now.
My first thought, Blackmogs, but all addresses are still there, particularly those with house names only. When I have a moment I'll email and ask.
