 In 1915 The Battle of Broken Hill took place when a New Year's Day picnic train from Broken Hill to Silverton was attacked by a gunman from Afghanistan, and modern-day Pakistan.Penrose Park, named after John Penrose, a pioneering brewer at Silverton, was the attraction for these picnic excursions.Located beside Umberumberka Creek in a rare belt of greenery at the outskirts of Silverton, it was not so much a product of the early mining era at Silverton as of the mining boom at Broken Hill.
