When Arthur Tully died of wounds in June 1918 he was 20 years old. And yet his number - LSR/2295 - dates to August 1914 and belongs to the series issued to the Royal Sussex Regiment Special Reserve - the 3rd Battalion. Of course, there was nothing unusual about men (or boys) joining up under age and Arthur appears to have fallen into that category. To be 20 years old in 1918 must have meant he was 16 in 1914 and was probably the reason he remained in England until 1917.
I'm guessing that his true age became apparent to the military authorities at some point and that he was retained in England until he became 19. If that was the case, it's unusual as I've seen countless service records of men who were discharged from the army having made a "mis-statement of age".
Arthur is buried at Varennes Military Cemetery in France. His headstone reads, PARTED ON EARTH / TO MEET IN HEAVEN.
