“STRATHALLAN AND THE GREAT WAR"

"That we know a little more about Allan Harley, is almost entirely due to an article that appeared in the Perthshire Advertiser in 1918."

“Educated firstly at Perth Academy, he later attended Strathallan as one of the original boarders in 1913, becoming Captain of School in 1916-17, with a distinguished academic and sporting record. He had passed the Junior Cambridge Examination in 1915, finishing second in the British Empire at his branch of study, then passed the Senior Cambridge in the first rank, at 16, the following year. During his last year the School eleven won every match during the cricket and football seasons. He was a great favourite with the boys in the School, especially the younger ones, and on going up to the ‘Varsity’ he was ‘chaired’ to the station by his admiring School fellows."

“In 1917 he was due to go up to Edinburgh University to study medicine but was instead called up for war service at age 18. Enrolling as a private in the Argyll and Sutherland Highlanders, after training he was seconded to the Seaforth Highlanders who saw action in the area near Arras and the Somme in the latter years of the war."

"Barely three days after landing in France Allan was listed as missing in action. His death is registered as 9th May 1918. He was buried in the Cabaret Rouge British Cemetery near Souchez in France. He was only 18."
