On 27 June 1918, the Llandovery Castle, a Canadian hospital ship returning to England, was sunk by a German U-boat in contravention of international law. Two hundred and thirty-four crew members died, including fourteen nursing sisters. It was the most significant Canadian naval disaster of the First World War. Anna Stamers, a thirty-year-old nursing sister from Saint John, was on the ship. Now, her story will finally be told. In this well-researched volume, Dianne Kelly explores Stamers’s childhood and nursing education in Saint John; her decision to enlist and her transition to military nursing; her service during the war in field hospitals in both England and France; and her final posting aboard HMHS Llandovery Castle. This vivid reconstruction of Stamers’s life is both an illuminating biography of a young woman’s experience of war and an important examination of the role nursing sisters played during the Great War.
