Pick of the Day
Tony Connelly: A Hidden History, 9.35pm, RTÉ One
Streaming on RTÉ Player
Produced as part of RTÉ’s Decade of Centenaries collection, this documentary tackles the difficult and contentious subject of the Royal Irish Constabulary - the British police force in Ireland until its disbandment in 1922.
Taking a break from his usual role reporting on breaking news of the war in Ukraine or Brexit, Tony sets out to discover more about his paternal grandfather, Michael Connelly, who served as a constable in the RIC during the War of Independence and who died before he was born.
Initially armed with only a few faded photographs and a handful of family stories, Tony knows only the bare bones of his grandfather’s life.
He is all-too aware that the RIC - and the men who served in it - are still regarded with anger and suspicion by some. They were seen as spies for the British, siding with the enemy, and the opponents of those who would rid us of an occupying nation.
Over 500 RIC men lost their lives at the hands of Republican forces, and many feel little sympathy for them, even today.
Piecing together his grandfather’s life from records, journals newspaper articles and other historical documents, Tony enlists the help of a group of experts, archivists, historians and – in one memorable encounter – the son of a man who was an active member of the IRA’s Third Tipperary Brigade.
This man not only writes in incredible detail about his dealings with Tony’s grandfather, but also concedes that he possibly owed his life to him.
