The rebellion was crushed and he was captured then tried and executed for high treason against the British king George III of Great Britain
Emmet’s speech to the court [The Speech from the Dock] could be regarded as the last protest of the United Irishmen:
‘ I have but one request to ask at my departure from this world – it is the charity of its silence. Let no man write my epitaph. No man can write my epitaph, for as no man who knows my motives and character dares now to vindicate them, let not prejudice or ignorance asperse them. Let them rest in obscurity and peace until other times and other men can do justice to them. When my country takes her place among the nations of the earth, then shall my character be vindicated, then may my epitaph be written’.
The whereabouts of his body remains a mystery. Emmet was a hero, in particular of Patrick Pearse.
