The
Irish National Invincibles failed numerous times to kill
Chief Secretary William Edward Forster before he resigned his office in protest at the
Kilmainham Treaty. The group then settled on a plan to kill the
Permanent Under-Secretary Thomas Henry Burke at the Irish Office. Newly installed Chief Secretary
Lord Frederick Cavendish, on the evening of his arrival to Ireland, decided to walk alone from Dublin Castle to his new residence in The Phoenix Park. Close to the entrance of Dublin Zoo, Burke, who just happened to also be on his way home to his residence in The Phoenix Park, spotted Cavendish and asked his carriage driver to stop and then continued on foot with Cavendish to
the Viceregal Lodge, the "out of season" residence of the
Lord Lieutenant of Ireland.
The Invincibles had been following Burke for a number of days previous to this. Seven members of
The Invincibles approached Burke and Cavendish. The first assassination was committed by
Joe Brady, who stabbed Burke with a 12-inch knife, followed in short order by Tim Kelly, who stabbed Cavendish. Both men used surgical knives, delivered by
Mary Ann Byrne, in order to avoid making a lot of noise while carrying out the killings. As previously mentioned, Cavendish had just arrived in Ireland that day so these men were completely unaware of his identity and he was not the intended target, however as he was now a witness to the assassination he could not be left alive.
Thomas Myles, resident surgeon at the nearby
Dr Steevens' Hospital, was summoned to render medical assistance to the victims. The Lord Lieutenant,
Lord Spencer, described hearing screams before witnessing a man running to the Lodge grounds shouting, "Lord Frederick Cavendish and Mr. Burke are killed!" The assailants were driven away in a cab by
James Fitzharris, known as "Skin-the-Goat", who served as a
getaway driver. ==Investigation==
