Ninety-eight years after Harry Beardsall died during the Battle of the Somme, his great-great-great grand niece, Charlotte Osmaston, plays the last post on his old bugle. It's the very same bugle Harry played just before he was hit, and killed, by artillery fire. His body was never found but the instrument was plucked from the battlefield. Charlotte payed the tribute at her Nelson College for Girls assembly. To tell us more we're joined by Charlotte's mother, Helen Beardsall.
