We do not have much information on J. L. Hargreaves. A John Leslie Hargreaves coming from Bradford and born in 1914 appears under the same name of J. L. Jarvis in the British registers of 1933, his mother’s last name being “Jarvis”. Thus, John Leslie Hargreaves would have served under his mother’s name, Jarvis.

 His father, James Hargreaves is registered as dead on the marriage certificate of his son with Clara Tubbs in September 1933. Perhaps John Leslie did not know him. Or maybe he decided to enlist using his mother's name for other reasons.

On the 9th of August, Hargreaves is with is battalion, the 6th Durham Light Infantry where he serves as lance serjeant.

With his comrades, they fight around Mont Pinçon.

The fight is relentless: by the end of the day, the battalion counts 10 dead and 50 injured. Hargreaves is one of them and evacuated to Roucamps where the headquarters of his battalion are established. 

There, he is buried with his comrades. Later, he is reburied at St Manvieu War Cemetery on the 14 of December 1945 where he still rests today.
