Letter from Bulmer Hobson (1883–1969) on Irish Volunteers notepaper to Joseph Mary Plunkett (1877-1916) requesting that a Brian MacMullen be allowed leave the camp (Larkfield Plunkett farm in Kimmage) to attend to some business regarding a house for Volunteers.John Bulmer Hobson was an Irish nationalist and a leading member of the Irish volunteers. In 1904, he became a member of the Irish Republican Brotherhood (IRB). He was kept unaware of the plans of the Rising; while he could detect some underground preparations he was unable to find any evidence for it. On discovery of the plans for the Rising, Hobson attempted to alert the other members of the Irish Volunteers; he was imprisoned at gunpoint, and kept hostage while the Rising was underway. After the Rising, Hobson went into hiding to avoid arrest, an action which hurt his future political prospects and led to rumors that he was a traitor to the Volunteers and the IRB.Joseph Mary Plunkett was an Irish poet, journalist and signatory of the Easter Proclamation. Plunkett suffered with tuberculosis, owing to illnesses in his childhood. He served as the chief military strategist of the Easter Rising, garnering German and American assistance for the struggle. Plunkett served in the GPO garrison, assisted by his aide de comp Michael Collins. Plunkett married Grace Clifford in the chapel of Kilmainham jail just hours before he was executed by firing squad on 4 May 1916.
