A report on the Tramore Races of unknown date gives us a last glimpse into Daniel’s life in the police force: A body of police under the command of sub-Inspector Jennings was called into active requisition to suppress numerous fights at intervals between races. One unfortunate jockey (Hogan from Tipperary) had a bludgeon broken over his head by an assailant. Several medical gentlemen were prompt in their attention to the poor fellow.
