1: "The Supreme Council of the IRB met on 5 September 1914, just over a month after the British government had declared war on Germany. At this meeting, they decided to stage an uprising before the war ended and to secure help from Germany." - Source: Max Caulfield "The Easter Rising" page 18

2: "After the war began, Roger Casement and Clan na Gael leader John Devoy met the German Ambassador to the United States, Johann Heinrich von Bernstorff, to discuss German backing for an uprising. Casement went to Germany and began negotiations with the German government and military. He persuaded the Germans to announce their support for Irish independence in November 1914." - Source: Foy and Barton "The Easter Rising" page 25

3: "Casement also attempted to recruit an Irish Brigade, made up of Irish prisoners of war, which would be armed and sent to Ireland to join the uprising. However, only 56 men volunteered. Plunkett joined Casement in Germany the following year. Together, Plunkett and Casement presented a plan (the 'Ireland Report') in which a German expeditionary force would land on the west coast of Ireland, while a rising in Dublin diverted the British forces so that the Germans, with the help of local Volunteers, could secure the line of the River Shannon, before advancing on the capital. The German military rejected the plan, but agreed to ship arms and ammunition to the Volunteers." - Sources: Townshend, Easter 1916, p. 104; Foy and Barton, The Easter Rising, p. 105; McNally and Dennis, Easter Rising 1916: Birth of the Irish Republic, p. 30 & Foy and Barton, The Easter Rising, pp.25-28

So Jom far from it being a lie we have the entire Supreme Council of the IRB agreeing to obtaining support from Germany a country at war with Great Britain at a meeting held on the 5th September 1914.

Roger Casement travels to Germany a country at war with Great Britain at the time.

Plunkett joins Casement in Germany to attempt to arrange a German invasion.

Below you will find how less than ten men subverted the wishes, aims and views of the "organisations" they were supposed to be part of:

"In May 1915, Clarke and MacDermott established a Military Committee or Military Council within the IRB, consisting of Pearse, Plunkett and Ceannt, to draw up plans for a rising. Clarke and MacDermott joined it shortly after. The Military Council was able to promote its own policies and personnel independently of both the Volunteer Executive and the IRB Executive. Although the Volunteer and IRB leaders were not against a rising in principle, they were of the opinion that it was not opportune at that moment. Volunteer Chief-of-Staff Eoin MacNeill, supported a rising only if the British government attempted to suppress the Volunteers or introduce conscription, and if such a rising had some chance of success. IRB President Denis McCullough and prominent IRB member Bulmer Hobson held similar views. The Military Council kept its plans secret, so as to prevent the British authorities learning of the plans, and to thwart those within the organisation who might try to stop the rising. IRB members held officer rank in the Volunteers throughout the country and took their orders from the Military Council, not from MacNeill."

On the Black & Tans Jom:

"The Black and Tans served in Ireland from the end of 1919 to some time in 1921"

The first deployment of the Black & Tans to Ireland was in March 1920. Their activities ended with the Truce that came into force in June 1921. 15 months Jom NOT two years – Steve Shaw will no doubt be able to explain the importance of you getting this right to you.
