Returning to Dublin in 1796, he was admitted to the Irish Bar, the
King's Inns, in
Michelmas term. The published records of the King's Inns state that he had been employed in the Irish revenue service. Magan's historical notoriety originates from a single act. During April–May 1798 he informed the British government several times of the whereabouts of
Lord Edward Fitzgerald on
Thomas Street, Dublin, just as the latter prepared to take the field at the head of thousands of
Croppies during the
1798 Rising. Lord Edward's arrest on 19 May deprived the
United Irishmen of their most charismatic leader, on whose head the British had put a price of £1,000, equivalent to £1.5m in 2015. Magan passed this to the Castle without being discovered or even suspected during his lifetime, probably because of his otherwise unremarkable life. He had found out Lord Edward's whereabouts through his involvement with the
United Irishmen, being a member of its committee responsible for Dublin. He hosted a meeting of this committee on the night of 17 May 1798. Lord Edward attended and may have passed the night in Magan's house. Magan sold this information on to
Dublin Castle the next day, provoking
Major Sirr with a body of soldiers to apprehend Lord Edward as he departed from the rear of 20
Usher's Island at dusk. Given further information by Magan, Sirr found Lord Edward suffering from fever in 153 Thomas Street and shot him during a struggle, and he died in
Newgate Prison, Dublin, some days later. It was only with the publication of
W. J. Fitzpatrick's
Secret Service Under Pitt a century later in 1892 that Magan was unveiled as the traitor. Francis Higgins was paid the £1,000 for betraying Lord Edward, and Magan got £300 a year. A fortune bequeathed by one Francis Magan led to the foundation of
St. Vincent's Hospital, Fairview,
Dublin in 1857. ==References==
