Denise Elizabeth Wynne (left), whose father, Dennis Morley, was a Lisbon Maru survivor, and several guests participate in the unveiling ceremony for the Memorial for Dongji Fishermen's Rescue of British Prisoners of War on an island in Dongji township, Zhejiang province, on Tuesday. In October 1942, the Lisbon Maru, a cargo vessel owned by the Japanese army used to transport more than 1,800 British POWs from Hong Kong to Japan, was struck by United States forces off the Zhoushan Islands. As the ship sank, local fishermen risked their lives to rescue over 300 people.
