This figure depicts Lieutenant Colonel Henry Darby Griffith, Commanding Officer of the 2nd Royal North British Dragoons, or Scots Greys. Griffith led the Regiment at the Battle of Balaclava, during the charge of the Heavy Brigade. Sadly, Griffith was one of the first casualties of the Greys as they started their charge. Unfortunately he was struck in the head, probably by a carbine bullet fired by a Russian cavalryman. So he only took part in the very first minutes of the action. That said, he seemed to have survived, because a check of the Balaclava casualty roll lists him as slightly wounded during the battle.
The figure is a Strelets plastic Scots Greys officer from the "Charge of the Heavy Brigade" box. He is mounted on a Douglas Miniatures metal horse:
