Thomas Thomson was the only son of James Thomson and Margaret Torrance who, at the time of Thomas' death in action, lived in Winchburgh, West Lothian. He was 28 years old when he died and was unmarried. Thomas was posthumously awarded the Military Medal for Gallantry. No official record of the reason for the award can be found but it is thought he was killed by a bullet to the stomach during an attempt to rescue an injured comrade from no-man's land. His medal was donated to the Royal Scots museum at Edinburgh Castle by his great-nephew, Peter McTiernan, so that it can be viewed by his family or anyone who wishes to remember and honour this brave and selfless young man.
