The Silver War Badge was instituted with effect from 12th September 1916. Round the edge it is inscribed 'For King and Empire...Services Rendered'.
The badge, mounted as a brooch, was awarded to soldiers who sustained a wound, or contracted sickness or disability in the course of the war which necessitated being invalided out. Each badge had a number on the back.
The reason for issue of this badge was to stop men of military age (not in uniform) being harassed, accused of cowardice and shown the 'White Feather'. It is wrong to describe it as a wound badge, as many recipients received it due to sickness and not wounds
About 1,150,000 badges were issued with certificates. A roll of the recipients of the War Badge can be found at the National Archive, Kew .
