Discharged on Conviction of Felony

[Hanford]

Looks like findmypast.co.uk has rights to his military records.

FORSTER    Ralph b 1877 Stockton on Tees, Durham  WO96 Militia

if you can find out where he was based the local court sessions probably will point to his conviction.

That's my man 
It says he is living in North Yard, Crofton, Yorkshire... I'll have a look at their archives when I'm more awake 

They are militia records so he would have been home based.

Ahh right, brilliant,  thank you
