19-year-old Gunner Reginald Dare Day, an Old Silhillian, was killed in action on 21st October 1917 whilst serving with the Royal Garrison Artillery. Solihull School during the First World War by John Loynton indicates that he was born in 1899 and entered school in 1910, leaving in 1913 after having passed the Preliminary Oxford Local Examinations.
He didn’t actually serve under his own name but, instead, served under the name William Cartledge Garner. This is quite clear from the Register of Soldiers’ Effects, which includes the name of 78623 William Cartledge Garner with an addition underneath in different handwriting: “alias Reginald Dare Day”. His next of kin is given as his brother, Andrew S. Day.
