[3] Like Joseph he was sent to England to be educated at the exclusive Catholic public school Stonyhurst College,[4] where he acquired his upper-class English accent.

These men on the run (including Michael Collins) had been staying at George's mother's Larkfield estate in Kimmage, then a country area just southwest of Dublin city making bombs for the Rising.

Famously on Easter Monday he waved down a tram with his revolver at Harold's Cross, near Kimmage, boarded it with his men (armed with shotguns, pikes and homemade bombs), took out his wallet and said, "Fifty-two tuppenny tickets to the city centre please".

[6][7] With a hundred other Volunteers they marched with James Connolly and Patrick Pearse to seize the General Post Office (GPO).

He ordered his men to move the huge rolls of printing paper to barricade O'Connell Street, which aided the spread of fire that burned down the GPO.

On 20 October 1917 he addressed a huge Sinn Féin meeting in Dungarvan Square with his father and a Volunteer cavalry section as a guard of honour.

When the Executive Council of the IRA realised that the British had given their enemies artillery to bombard the Four Courts Rory O'Connor and Ernie O'Malley were concerned about the effect it would have on the men; George said, "You get used to it… it's not bad".

In one body "were included Maud Gonne MacBride, solid IRA men like George Plunkett and Seán MacBride, Mary MacSwiney, JJ O'Kelly and the de jure Republicans; the Republican Left like Frank Ryan and Mick Fitzpatrick, firm Sinn Féin people like Joe Clarke…", but they soon split again.

Tom Barry advocated using Nazi Germany as a source of arms and funds in the late 1930s; this was rejected by Plunkett and the Army Council.

[16] George Plunkett died in Dundalk on 21 January 1944 from a fractured skull, sustained in falling from a horse-drawn trap in Ballymascanlon, where he was living with his family.
