27 August – On this day

Lord Louis Mountbatten is killed when Irish Republican Army (IRA) terrorists detonate a bomb on board his fishing vessel Shadow V while holidaying in Ireland.

Mountbatten went lobster-potting and tuna fishing in his 30-foot (9.1 m) wooden boat, the Shadow V, which had been moored in the harbour at Mullaghmore. IRA member Thomas McMahon had slipped onto the unguarded boat that night and attached a radio-controlled bomb weighing 50 pounds (23 kg). When Mountbatten was aboard, just a few hundred yards from the shore, the bomb was detonated.

There were a total of 7 people on board the vessel when the bomb detonated. Mountbatten was critically injured and died before rescuers could bring him to shore. His 14-year-old grandson Nicholas Knatchbull and a young crew member Paul Maxwell (15 years old) were killed by the blast. All the rest of the passengers were seriously injured, and Baroness Brabourne (aged 83) died from her injuries the following day.
