This is all i have to work off, from the 2nd post on this topic:
Statement, 4828 Pte A. McKELL, B Company, 53rd Bn, 30 December 1918: '[He was] Of B. Coy. on 19th July at Fleurbaix during general action, was killed by bullet, don't know where hit. I saw his body on the field, in No Man's Land, close to L/Cpl. E.A. Hubbard, and J. LARKIN. We were taken P/W next day.'
I can probably find McKell, as 4828 might be his number...
