Britain's Prince Charles, Prince of Wales (L) reads a letter from his great-uncle Lord Mountbatten shown to him by Daithi O'Dowd during a visit to the village of Mullaghmore in Ireland on May 20, 2015 where Lord Mountbatten was killed in an Ire bombing in 1979. Britain's Prince Charles spoke of his "anguish" at the murder of his godfather by IRA paramilitaries in 1979 as he became the first royal to visit the assassination site in Ireland. Charles remembered Lord Louis Mountbatten as "the grandfather I never had" on an emotional trip to the rugged coastline, saying he understood the suffering of the Irish people in "a profound way".
