The true story of a small brown donkey called Murphy, chosen to be an 'ambulance' in WW1, bringing wounded soldiers over the hilly, craggy terrain to the field hospital. The donkey served his soldier Simpson well and never gave up or complained; he worked to the point of exhaustion, saving hundreds of lives. At the end of the battle, when the time came for the donkeys to be sold on to locals, Simpson was desperate to protect Murphy - fixing a brown luggage label to Murphy's harness saying 'NOT for sale'.
