They seem to come up all the time.  This one was awarded to Private Thomas Byrne who fought in the last major British cavalry charge by the 21st Lancers at the battle of Omdurman in 1898.  But it is worth noting that three times as many horses were slaughtered as Lancers and yet none got a medal or a mention.  Unthanked and unacknowledged, horses have been horribly expendable down the ages.
