Editing Lord Mountbatten (section)

=== Aftermath ===
Two hours before the bomb detonated, Thomas McMahon had been arrested at a Garda checkpoint between [[Longford]] and [[Granard]] on suspicion of driving a stolen vehicle. He was tried for the assassinations in Ireland and convicted on 23 November 1979 based on forensic evidence supplied by [[James O'Donovan]] that showed flecks of paint from the boat and traces of nitroglycerine on his clothes.<ref>{{cite news |url=https://www.telegraph.co.uk/news/uknews/law-and-order/5995439/Killer-of-Lord-Mountbatten-enjoys-freedom-30-years-on-from-IRA-murder.html |archive-url=https://ghostarchive.org/archive/20220110/https://www.telegraph.co.uk/news/uknews/law-and-order/5995439/Killer-of-Lord-Mountbatten-enjoys-freedom-30-years-on-from-IRA-murder.html |archive-date=10 January 2022 |url-access=subscription |url-status=live |title=Killer of Lord Mountbatten Enjoys Freedom, 30&nbsp;Years on from IRA Murder |work=The Telegraph |location= London |date=9 August 2009 |access-date=20 September 2012}}{{cbignore}}</ref> He was released in 1998 under the terms of the [[Good Friday Agreement]].<ref name=onthisday /><ref>{{harvp|Moloney|2002|p=176}}.</ref>

On hearing of Mountbatten's death, the then [[Master of the Queen's Music]], [[Malcolm Williamson]], wrote the ''Lament in Memory of Lord Mountbatten of Burma'' for violin and string orchestra. The 11-minute work was given its first performance on 5 May 1980 by the Scottish Baroque Ensemble, conducted by Leonard Friedman.<ref>{{cite news |url=https://www.theguardian.com/news/2003/mar/04/guardianobituaries.artsobituaries |department=Obituary |title=Malcolm Williamson |newspaper=The Guardian |location=London |date=4 March 2003 |access-date=20 September 2012 |archive-date=27 April 2019 |archive-url=https://web.archive.org/web/20190427084729/https://www.theguardian.com/news/2003/mar/04/guardianobituaries.artsobituaries |url-status=live }}</ref>
