This is a letter that my Grandmother received when my father was injured in WW1. The letter was sent from The General Hospital and is dated 27th July 1916. It says "I regret to inform you 2763.... was admitted here suffering from gunshot wounds chest, arm and leg. Condition is serious. I will let you know how he progresses in a few days".
It must have been very difficult for her as she didn't know whether he would survive. Prior to this he'd been reported missing in action. He did recover and return home, but he did suffer from the after effects of the wounds for the rest of his life and shrapnel remained in his body.
