between 1864 and 1867, the Royal Irish Constabulary established an
intelligence department based at Dublin Castle that recruited infor-
mants, including Thomas Beach, alias ‘‘Major Henri le Caron.’’ Col-
onel William Fielding of the Coldstream Guards was assigned to
London to work on secret service. Dublin Castle experienced consid-
erable success in foiling various plots, including an attempt to raid
the arsenal at Chester Castle in February 1867 and a plan to assassi-
nate Queen Victoria as she returned to London from Balmoral, and
was instrumental in the arrest of Fenian leader James Kelly in Man-

was disbanded at the end of March 1868, the government having con-
cluded that the threat from Irish nationalists was exaggerated.
