On May 7, 1915, one of the most brutal attacks on civilians during World War One took place when RMS Lusitania was torpedoed.
Despite warnings that the vessel would face danger, more than 2,000 people were travelling from New York to Liverpool when she was attacked.
A small fishing boat, The Wanderer, from Peel, Isle of Man, was the first on the scene. The crew of seven rescued more than 150 people from the freezing waters. Letters home reveal the devastation they witnessed.
