In occupied Holland, owning a radio could mean death — unless you hid it inside a picture frame. This episode uncovers the incredible ingenuity of the Dutch resistance and the secret BBC receivers disguised as everyday objects to evade Gestapo detection. Battle Treasures tells the stories behind some of the rarest and most remarkable military artefacts ever discovered. Hosted by Jason Fox and Bruce Crompton, each episode explores three extraordinary items - revealing their provenance, the battlefield stories behind them, and little-known facts to bring each object to life.
