Thomas Slater, born in Scotland, joined the IRB in 1905 at Peadar Kearney’s urging. He was 17 years old. The earlier part of his statement describes early recruitment to the IRB, its resurgence with an influx of younger members, and the establishment of the Irish Volunteers. Slater became adjutant with C Company, 2nd Battalion. He was active in the Howth gun-running, and attended the funeral of O’Donovan Rossa.

He details McDonagh’s decisions not to occupy Trinity College or the Telephone Exchange, arguably bad military omissions.
