Editing Seán Lemass (section)

===Anti-treaty===
In December 1921, after the signing of [[Anglo-Irish Treaty]], Lemass was released. He became a training officer for a period in [[Beggars Bush Barracks]] before the IRA split and was involved in the Belfast Boycott operations (see [[The Troubles in Ulster (1920–1922)]]). During the debates of the Anglo-Irish Treaty in 1921, Lemass was one of the minority who opposed it along with de Valera. As a protest, all the anti-Treaty side withdrew from the [[Dáil]]. In the [[Irish Civil War]] which followed Lemass was adjutant to [[Rory O'Connor (Irish republican)|Rory O'Connor]], when the group seized the [[Four Courts]], the home of the [[High Court (Ireland)|High Court]] of Ireland. The occupation of the Four Courts eventually resulted in the outbreak of the Civil War, when, under British pressure, the Free State side shelled the building on 28 June 1922.<ref>C Townshend, "The Republic", p.412</ref> As a result, [[Battle of Dublin (1922)|fighting broke out in Dublin]] between pro and anti-Treaty factions. The Four Courts surrendered after two days of bombardment, however, Lemass escaped with [[Ernie O'Malley]] and some others to [[Blessington]].<ref>M. Hopkinson, "Green against Green", p.143-44.</ref> Their [[Flying Column]] operated in [[Enniscorthy]], [[Tullow]], [[Ferns, County Wexford|Ferns]], [[Baltinglass]] and [[Borris, County Carlow|Borris]] before the Column was broken up. Lemass and O'Malley returned to Dublin along with [[Thomas Derrig]] as a member of the IRA Eastern Command Headquarters but were later captured in December 1922 and interned in the [[Curragh Camp]].<ref name=dib/>

In June 1923, after the end of the civil war, Seán Lemass's brother Noel Lemass, an anti-Treaty IRA officer, was abducted in Dublin by a number of men, believed to be connected to the [[National Army (Ireland)|National Army]] or the Police [[Criminal Investigation Department (Ireland)|CID]] unit.<ref>[http://www.oup.co.uk/pdf/0-19-820426-4.pdf#search=%22noel%20lemass%20Irish%20civil%20war%20oriel%20house%22 ''The State and Civil War'', 1921–1923] {{webarchive|url=https://web.archive.org/web/20051102074437/http://www.oup.co.uk/pdf/0-19-820426-4.pdf |date=2 November 2005 }}, Oxford University Press</ref> He was held in secret until October when his mutilated body was found in the Dublin Mountains,<ref>{{cite book|last=Buning|first=Marius|title=Historicising Beckett: issues of performance  |editor=Marius Buning|publisher=Rodopi|year=2005|volume=15 of Samuel Beckett today/aujourd'hui|isbn=978-90-420-1767-2|url=https://books.google.com/books?id=POGHjjvY5g4C&q=%22Featherbed+mountain+in+dublin%22&pg=PA118|access-date=14 August 2009}}</ref> (see also [[Executions during the Irish Civil War]]).
