The 1901 Census shows Leonard, at the age of 12, living at 2 Lime Grove, Cheadle, with his parents, Horace and Elizabeth and three older brothers and a sister, Horace, Frank, Jane and Harold. Nothing is known about Leonard's later life, other than the fact he enlisted in the army in Stockport.
10th March 1915 was the opening day of the Battle of Neuve Chappelle, however the 1st Grenadiers were held in reserve all day. They were moved up towards the front line but when the attack by the leading battalions failed they returned to the billets until the following morning. On the 11th, the 1st battalion did attack but suffered very heavy casualties, mainly in No. 2 Company, from enfilading machine gun fire.
It is surprising, therefore, that official records record that Leonard was one of 57 guardsmen killed on the 10th, yet record only 5 killed on the 11th. It must be presumed that, in the heat of battle, the officer recording the information made an error and , in fact, the deaths occurred during the attack on the 11th.
