IRISH REVOLUTIONARY. EXECUTED 1916.
In September 1915 Mac Diarmada joined the secret Military Committee of the IRB, which was responsible for planning the rising. Indeed Mac Diarmada and Clarke were the people most responsible for it. Due to his disability, Mac Diarmada took little part in the fighting of Easter week, but was stationed at the headquarters in the General Post Office (GPO), as one of the Provisional Republican Government.
Following the surrender, he nearly escaped execution by blending in with the large body of prisoners. He was eventually recognised by Daniel Hoey of G Division. Following a court-martial on 9 May, Mac Diarmada was executed by firing squad on 12 May at the age of 33. In September 1919 Hoey was shot dead by Michael Collins’s Squad.
