Lord Mountbatten
Lord Mountbatten

On 27 August 1979 Lord Mountbatten was assassinated off the coast of Mullaghmore, Ireland. A bomb was planted on Mountbatten's boat by Thomas McMahon during Mountbatten's annual summer trip to Classiebawn Castle. McMahon was an Irish republican and volunteered for the Provisional Irish Republican Army (IRA), which planned the attack for several months. A bomb team built a device that contained fifty pounds (23 kg) of gelignite. The bomb killed Mountbatten less than two hours after its detonation, along with his grandson Nicholas, Nicholas's grandmother Doreen, and crew member Paul Maxwell.

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
