 The information was passed to the Under-Secretary for Ireland, Sir Matthew Nathan, on 17 April, but without revealing its source, and Nathan was doubtful about its accuracy.When news reached Dublin of the capture of the "Aud" and the arrest of Casement, Nathan conferred with the Lord Lieutenant, Lord Wimborne.Nathan proposed to raid Liberty Hall, headquarters of the Citizen Army, and Volunteer properties at Father Matthew Park and at Kimmage, but Wimborne insisted on wholesale arrests of the leaders.
