Joseph O'Sullivan, along with fellow Irish Republican Army (IRA) volunteer Reginald Dunne, shot dead Field Marshal Sir Henry Wilson outside Wilson's home at 36 Eaton Place, Belgravia, London on 22 June 1922. Many Irish Republicans believed that this killing precipitated the start of the Irish Civil War. Convicted by a jury, he was sentenced to death by Mr Justice Shearman. Irish leader Éamon de Valera made a statement on the possible reason for the killing of Wilson: "I do not know who they were that shot Sir Henry Wilson, or why they shot him...I know that life has been made a hell for the Nationalist minority in Belfast and its neighborhood for the past couple of years"..
