Lieutenant James Young Milne-Henderson, 11th Battalion Highland Light Infantry, was killed in action on July 31, 1917, at the Battle of Flanders, aged 26. Born in Edinburgh on March 9, 1891, Henderson was educated at George Watson’s College, where, when thirteen years old, he was already in the 2nd XV, getting his 1st XV cap when only fifteen. It is said of him that he was the best stand-off half ever produced by Watson’s College, He was a very versatile gamesman, and did great things for the Watsonians’ XV, besides being good at cricket, hockey, swimming, badminton, and billiards. He was certainly the next best to P Munro I have ever seen in Scotland’s National XV. He was fated to play but once therein, and that was in the first Calcutta Cup match played at Twickenham, when he played a game that augured very well indeed for his and Scotland’s future.
