He had just listened to Minister for Defence <a href=\"https:\/\/www.dib.ie\/biography\/gibbons-james-m-jim-a3454\" target=\"_blank\" rel=\"noopener\">Jim Gibbons<\/a> in a Cabinet meeting \u2018waxing patriotic and accusing us of recognising the border\u2019. Venting by putting his thoughts on paper, he continued &#8216;country is full of heroes who are willing to wage total war in words now that somebody has decided on a line of action which protects them.\u2019<\/p>\n<p>As rioting and violence broke out across Northern Ireland <a href=\"https:\/\/www.rte.ie\/archives\/exhibitions\/1042-northern-ireland-1969\/1048-august-1969\/\" target=\"_blank\" rel=\"noopener\">in August 1969<\/a>, the <a href=\"https:\/\/www.military.ie\/en\/\" target=\"_blank\" rel=\"noopener\">Defence Forces<\/a> sent field hospitals and support units to the border to treat casualties who did not want to be treated in Northern Ireland hospitals. One of Hillery\u2019s colleagues said the soldiers were \u2018like hypnotised hens\u2019 stopping at the border which was nothing but a line on the map and the Minister for Defence \u2018should put it right&#8217;.<\/p>\n<p>The future president was not impressed. \u2018The mouthing of such inanities within Government and maybe without would make it impossible for any serious member to carry out a task on behalf of that government&#8217;, wrote Hillery. \u2018Frankly, the Army was not equipped or capable of doing what some people would like it to do.\u2019<\/p>\n<p alt=\"RT\u00c9 News : Broadcast By An Taoiseach\" class=\"tpe\" data-description=\"Broadcast by An Taoiseach Jack Lynch, 1969.\" data-embed=\"rte-player\" data-id=\"11070931\" data-ot-category=\"C0004\" data-title=\"Broadcast by An Taoiseach Jack Lynch, 1969.\">We need your consent to load this rte-player contentWe use rte-player to manage extra content that can set cookies on your device and collect data about your activity.

The Irish Defence Forces have been historically and habitually let down by their political masters when it comes to <a href=\"https:\/\/www.rte.ie\/news\/ireland\/2024\/1002\/1473110-raco-defence-conference\/\" target=\"_blank\" rel=\"noopener\">funding<\/a>.

Most of all, they didn&#8217;t have the sheer numbers to mount any form of expeditionary force, let alone to invade even the smallest part of Northern Ireland. \u2018Lashings of creamy patriotic ballad singing\u2019 in Cabinet, as Hillery put it, masked this reality with na\u00efve, green political rhetoric.<\/p>\n<p>At a subsequent Cabinet meeting on February 6th 1970, Minister for Defence Gibbons orally instructed the Chief of Staff of the Defence Forces, Lieutenant General <a href=\"https:\/\/www.dib.ie\/biography\/mac-eoin-sean-a5033\" target=\"_blank\" rel=\"noopener\">Se\u00e1n MacEoin<\/a> &#8216;to prepare and train the Army for incursions into Northern Ireland\u2019. When asked by Gibbons what were the \u2018critical deficiencies\u2019 he faced, MacEoin replied \u2018manpower, armoured fighting vehicles, transport\u2019. In effect, the items even a basic mechanised infantry force requires to operate, not to mention air cover and heavy weapons of various types and combat engineering equipment.<\/p>\n<p alt=\"Libraries and Archives Video\" class=\"tpe\" data-description=\"Libraries &amp; Archives video clips\" data-embed=\"rte-player\" data-id=\"3325259\" data-ot-category=\"C0004\" data-title=\"Libraries &amp; Archives video clips\">We need your consent to load this rte-player contentWe use rte-player to manage extra content that can set cookies on your device and collect data about your activity.

MacEoin looked for clarification and Gibbons provided this explanation on February 13th 1970. \u2018Incursions would be mounted only in circumstances where there would be a complete breakdown of law and order in Northern Ireland and where the security forces were unable or unwilling to protect the minority. The sole object of the incursions would be the protection of the lives and property of the minority\u2019.<\/p>\n<p>Like all military forces, the Defence Forces plan for contingencies with operations it is never called upon to undertake. One such was called \u2018<a href=\"https:\/\/en.wikipedia.org\/wiki\/Exercise_Armageddon\" target=\"_blank\" rel=\"noopener\">Exercise Armageddon<\/a>\u2019 which war-gamed the case of \u2018Armageddon\u2019 in Northern Ireland. But it would, as the name suggested, be an apocalypse for the young soldiers of the Defence Forces if they were sent into combat against the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Royal_Ulster_Constabulary\" target=\"_blank\" rel=\"noopener\">RUC<\/a>, the newly formed <a href=\"https:\/\/www.nam.ac.uk\/explore\/ulster-defence-regiment\" target=\"_blank\" rel=\"noopener\">Ulster Defence Regiment<\/a> (UDR), the British Army and various other hostile groups including the <a href=\"https:\/\/www.rte.ie\/centuryireland\/articles\/ulster-volunteer-force-to-form-separate-division-in-the-british-army\" target=\"_blank\" rel=\"noopener\">UVF<\/a>. The Government spoke of the Defence Forces undertaking \u2018mercy missions\u2019 into Northern Ireland; a suicide mission was a more appropriate term.<\/p>\n<p>In summer 1971, in the context of ensuring the security of the Irish state in light of the worsening situation in Northern Ireland, a new Minister for Defence, <a href=\"https:\/\/www.dib.ie\/biography\/cronin-jeremiah-jerry-a2218\" target=\"_blank\" rel=\"noopener\">Jerry Cronin<\/a>, and the Chief of Staff of the Defence Forces, Major General Thomas O\u2019Carroll, returned to the contingency of the Defence Forces having to cross the Border. Their hypothesis was that this might be required in the same &#8216;mercy mission&#8217; scenario discussed in 1970.<\/p>\n<p alt=\"RT\u00c9 News : Refugees From Northern Ireland\" class=\"tpe\" data-description=\"Refugees from Northern Ireland arrive in the Republic of Ireland, 1971.\" data-embed=\"rte-player\" data-id=\"11328446\" data-ot-category=\"C0004\" data-title=\"Refugees from Northern Ireland arrive in the Republic of Ireland, 1971.\">We need your consent to load this rte-player contentWe use rte-player to manage extra content that can set cookies on your device and collect data about your activity.

Dublin was coming to realise that it was possible, though unlikely, that Britain could simply leave Northern Ireland and the province would descend into civil war.<\/p>\n<p>O\u2019Carroll\u2019s analysis in these two scenarios was blunt and left his minister in no doubt. The British Army could field 12,500 men within Northern Ireland alone before reinforcement from the mainland, including artillery regiments, armoured regiments and Royal Marines. There was also 4,000 members of the UDR, 3,000 Army reservists and an estimated 100,000 unionists aged 18 to 30 who held many of the 102,000 licensed weapons in private hands in Northern Ireland. In contrast, the Defence Forces numbered 8,500 on paper and O\u2019Carroll estimated the number of combat capable soldiers at 2,300. He knew that his force was \u2018critically understrength\u2019 and, in effect, disregarded his own reserves and <a href=\"https:\/\/en.wikipedia.org\/wiki\/Army_Reserve_(Ireland)\" target=\"_blank\" rel=\"noopener\">the FC\u00c1.<\/a><\/p>\n<p>Accordingly, any action by the Defence Forces in Northern Ireland would be \u2018a gesture\u2019. O&#8217;Carroll maintained that \u2018no penetration in depth could be made and in the face of the superior forces which could be mustered against the invasion, destruction, capture or withdrawal of the Force would be inevitable.\u2019 He concluded that \u2018failure in any of these operations would be a blow both to military and national morale and to national prestige.\u2019<\/p>\n<blockquote>\n<p>Frankly, the Army was not equipped or capable of doing what some people would like it to do.<\/p>\n<\/blockquote>\n<p>This last point, the blow to \u2018national prestige\u2019, was critical. In 1971, both Ireland and Britain were negotiating to join <a href=\"https:\/\/en.wikipedia.org\/wiki\/European_Economic_Community\" target=\"_blank\" rel=\"noopener\">the EEC<\/a>. A war or even a border skirmish between two EEC applicant states was unthinkable. Ireland, the aggressor, would wave goodbye to its chances of entering Europe, dashing a core goal of Irish foreign and economic policy going back to the late 1950s. It would also go against the very nature of Ireland\u2019s UN membership and of Article 29 of <a href=\"https:\/\/www.irishstatutebook.ie\/eli\/cons\/en\/html\" target=\"_blank\" rel=\"noopener\">Bunreacht na h\u00c9ireann<\/a> which held Ireland to the peaceful settlement of international disputes.<\/p>\n<p>While \u2018ballad singers\u2019 continued to assail Hillery and Taoiseach <a href=\"https:\/\/www.dib.ie\/biography\/lynch-john-mary-jack-a4947\" target=\"_blank\" rel=\"noopener\">Jack Lynch<\/a>, it was ultimately diplomacy and political means that Dublin used with greater effect to stabilise and bring peace to Northern Ireland.
