Info required 5247805 Pte Ernest Walter MITCHELL

Not sure which you meant, both the casualty list and newspaper can be viewed on Findmypast - a subscription site.
Anticipating your next question I am afraid that the casualty lists are just that, a list, no further information is given as to circumstances etc.

As suggested above his death certificate should provide the cause of death but if you would like to follow his military service then send off for his service records.

Here is the CWGC details that will suffice for his service records.
