If a soldier was wounded or sick and was discharged from the army, they could be entitled to a silver war badge.
The main purpose of the badge was to prevent men not in uniform and without apparent disability being thought of as shirkers – it was evidence of having presented for military service, if not necessarily serving for long.
You would also get the King’s Certificate of Discharge.
This page from the Roll of Individuals entitled to a war badge, contains my wifes Grandad Frederick Carter – Leicestershire Reg no 32834 – enlisted 26.10.1916 – Discharged 10.01.1919 age 31, of wounds and served overseas. It was compiled in Lichfield. This is of great help to me as his service and pension records must be among the burned records that were destroyed in WW2.
