Conscription Crisis of 1918 The Conscription Crisis of 1918 stemmed from a move by the British Government to impose conscription ( military draft ) in Ireland during the First World War . Vigorous opposition was led by the trade unions , nationalist parties and Roman Catholic bishops and priests . A conscription law was passed but was never put in effect ; no - one in Ireland was successfully drafted into the army . The proposal and backlash galvanised support for an independent Ireland . Background . From early 1918 , the British Army were dangerously short of troops for the Western Front . In the German Spring Offensive of 1918 , German troops broke through the Allied lines in several sectors of the front in France , with a local advantage in numbers of four to one , putting severe strain on the Allied armies . The British Army , in one day , suffered a stunning setback , with the enemy over - running ninety - eight square miles of territory , and penetrating , at the furthest point , to a depth of four and a half miles . Conscription in Great Britain had already been established by the Military Service Act of January 1916 , which came into effect a few weeks later in March 1916 . By 1918 David Lloyd George was Prime Minister , leading a coalition Government , and in addressing a very grave military situation it was decided to use a new Military Service Bill to extend conscription to Ireland and also to older men and further groups of workers in Britain , thus reaching untapped reserves of manpower . Lloyd George connected the new conscription legislation to a new Home Rule Bill , which had the effect of alienating both nationalists and unionists in Ireland . Despite opposition from the entire Irish Parliamentary Party , conscription for Ireland was voted through at Westminster . Although large numbers of Irishmen had willingly joined Irish regiments and divisions of the New Army at the outbreak of war in 1914 , the likelihood of enforced conscription created a backlash . This reaction was based particularly on the fact that implementation of the Government of Ireland Act 1914 ( as previously recommended in March by the Irish Convention ) was controversially linked with a " dual policy " enactment of the Military Service Bill . The linking of conscription and Home Rule outraged the Irish nationalist parties at Westminster , including the IPP , AFIL and others , who walked out in protest and returned to Ireland to organise opposition . Although the crisis was unique in Ireland at the time , it followed similar campaigns in Australia ( 1916 – 17 ) and Canada ( 1917 ) . In Australia , Irish Roman Catholics mostly opposed conscription ; in Canada ( and the US ) the Irish Catholics supported conscription . Conferences and pledge . On 18 April 1918 , acting on a resolution of Dublin Corporation , the Lord Mayor of Dublin ( Laurence O ' Neill ) held a conference at the Mansion House , Dublin . The Irish Anti - Conscription Committee was convened to devise plans to resist conscription , and represented different sections of nationalist opinion : John Dillon and Joseph Devlin for the Irish Parliamentary Party , Éamon de Valera and Arthur Griffith for Sinn Féin , William O ' Brien and Timothy Michael Healy for the All - for - Ireland Party and Michael Egan , Thomas Johnson and W X O ' Brien representing Labour and the Trade Unions . On the evening of the same day , the Roman Catholic bishops were holding their annual meeting and declared the conscription decree an oppressive and unjust law , calling on the Church ' s adherents to resist " by the most effective means at our disposal " ( if " consonant with the law of God . " ) The Anti - Conscription Committee and bishops proposed an anti - conscription pledge that was to be taken at the church door of every Roman Catholic parish the next Sunday , 21 April , which read : Strikes and other actions in Ireland . Following their representation at the Mansion House , the labour movement made its own immediate and distinctive contribution to the anti - conscription campaign . A one day general strike was called in protest , and on 23 April 1918 , work was stopped in railways , docks , factories , mills , theatres , cinemas , trams , public services , shipyards , newspapers , shops , and even Government munitions factories . The strike was described as " complete and entire , an unprecedented event outside the continental countries " . In the following weeks , anti - conscription rallies were held nationwide , with 15 , 000 people attending a meeting in County Roscommon at the start of May , where John Dillon , leader of the Irish Parliamentary Party and Éamon de Valera of Sinn Féin shared the platform in a united cause . This in itself is notable as , while sharing nationalist views , Dillon and de Valera ' s parties had previously been divided in opinion as to the means of gaining legislative or complete independence from the United Kingdom . On 11 June Dublin ' s Lord Mayor , Laurence O ' Neill , in a letter to the President of the United States Woodrow Wilson called for support against conscription : Over a year earlier Wilson had introduced the Selective Service Act of 1917 ; by June 1917 it enabled the registration of all American men aged between 21 and 31 for conscription . The " plot " . Nervous of growing unrest , and still with dire need to progress conscription in Ireland , Lloyd George ' s government undertook several initiatives to quell the backlash . As Sinn Féin was publicly perceived to be the key instigator of anti - government and anti - conscription feeling , the viceroy Lord French , claiming evidence of a treasonable plot between Sinn Féin and the Germans , ordered the arrest of seventy - three Sinn Féin leaders , including Griffith and de Valera , on 17 May . This heavy - handed response by the Dublin Castle authorities did little to defuse the situation . ( In fact , a lack of evidence meant the German Plot was little believed in Great Britain , Ireland or the United States , and aggravated opinion and Sinn Féin support . ) Hay Plan . Simultaneously , a more subtle effort ( and possibly with more potential for success ) was undertaken from the offices of Lord Northcliffe under the Minister of Information . The " Hay Plan " was conceived by Stuart Hay — a British Army Captain — who was under orders to establish a proposal to work around widespread anti - conscription feeling and persuade Irish nationalists to join the French army ( initially as labourers in specialised battalions ) . Hay ' s plan relied on the power of the Roman Catholic Church in Ireland ( and empathy among its supporters for fellow - Catholics in Belgium and France suffering from German invasion ) , to sway opinion : The plan simply called for a letter ( drafted by Hay , and approved by Edward Shortt , then Chief Secretary for Ireland ) to be sent by the French Primate to the Irish bishops , requesting that they soften their opposition to conscription to aid the war effort in France . Despite some progress in August in persuading Primate of All Ireland Cardinal Logue through these means , the " Hay Plan " was delayed ( and ultimately stymied ) by complications in diplomatic channels and by political rivalries . In France the German Spring Offensive and its follow - on attacks had failed by July , and the Allies counter - attacked successfully at the Second Battle of the Marne and the Hundred Days Offensive . As a result , recruitment efforts through September and October continued to have very limited success , and by the Armistice in November ( marking the end of World War I ) conscription remaining unimplemented in Ireland . After - effects . By June 1918 it had become apparent to most observers in Britain and Ireland that following American entry into the war the tide of war had changed in favour of the Allied armies in Europe , and by 20 June the Government had dropped its conscription and home rule plans , given the lack of agreement of the Irish Convention . However the legacy of the crisis remained . Completely ineffectual as a means to bolster battalions in France , the events surrounding the Conscription Crisis were disastrous for the Dublin Castle authorities , and for the more moderate nationalist parties in Ireland . The delay in finding a resolution to the home rule issue , partly caused by the war , and exaggerated by the Conscription Crisis in Ireland , all increased support for Sinn Féin . Sinn Féin ' s association ( in the public perception at least ) with the 1916 Easter Rising and the anti - conscription movement , directly and indirectly led on to their landslide victory over ( and effective elimination of ) the Irish Parliamentary Party , the formation of the first Dáil Éireann and in turn to the outbreak of the Anglo - Irish War in 1919 . " ( See : Aftermath of World War I – United Kingdom and Irish ( UK ) general election , 1918 ) . This opposition also led in part to Sinn Féin being ignored by the subsequent victors at the Paris Peace Conference in 1919 , despite its electoral success . It appointed representatives who moved to Paris and several times requested a place at the conference , with recognition of the Irish Republic , but never received a reply . The crisis was also a watershed in Ulster Unionism ' s relations with Nationalist Ireland , as expressed by Unionist leader James Craig : " for Ulster Unionists the conscription crisis was the final confirmation that the aspirations of Nationalists and Unionists were unrecompatible . " Voluntary enlistment . It should be noted that the bulk of opposition to the Great War in Ireland was to compulsory conscription , not to the war nor to voluntary enlistment in the British Army . In fact , many Irish supported the war and Irish involvement . Support and enlistment were more prominent amongst Irish Unionist and Protestant traditions , but nationalist and Roman Catholic enlistment was also common , as the war was seen to be fought in defence of smaller Catholic countries like occupied Belgium . In this cause , those who would later become detractors of conscription ( including John Dillon , William O ' Brien and the Roman Catholic bishops ) were prominent on recruitment platforms at the outbreak of the war . In all , 200 , 000 to 300 , 000 Irishmen served with British forces during the Great War , and , of the 680 , 000 fatalities from the United Kingdom of Great Britain and Ireland , some 40 , 000 to 49 , 000 were from Ireland . In all about 12 . 3 per cent of Irish men of service age actually served , approximately 25 per cent of the rate in the rest of the UK ; 57 per cent of them were Roman Catholics .
