In this episode of Shipwreck Tales, Graeme Hill is joined by maritime historian John McCrystal to unravel the strange fate of the USS Memphis, a once-powerful American naval cruiser wrecked off Santo Domingo in 1916. What begins as a story of an ageing warship, superstition, and naval routine becomes something far stranger: a calm Caribbean afternoon, an unexplained wall of water, and a desperate race to raise steam before the sea overtakes the ship. Hill and McCrystal bring the tale to life with sharp curiosity and vivid detail, exploring whether the disaster was caused by a tsunami, a hurricane-driven storm surge, or simply one of the most freakish waves ever recorded.
