Notes
Hornshaw and Fowler found an Arthur Ogden as a Halifax casualty but he served with the Northumberland Fusiliers according to the Halifax Weekly Guardian of 21st July 1917. The CWGC lists him as at least serving with the West Riding Regiment but with their 10th Battalion, dying on 16/2/1917 and commemorated on the Thiepval Memorial. This uncertainty leads to no further details being used.
