Or bone meal fertilizer. I think he was okay. I found this out about him..
William Grant fought as a Sergeant in Captain John Warren’s company of the 92nd Highlanders at Waterloo. He was shortly afterwards promoted to Sergeant-Major and, on 5 November 1819, he was appointed Adjutant with the rank of Ensign. He did not live to claim a Peninsula Medal.
I'd probably need a paid Ancestry account to get any more information. Not sure what year they started awarding peninsula medals .
