with photograph portrait of Casement on cover. Leaflet printed by Fergus O'Connor, Dublin. Roger Casement (1864-1916), a respected diplomat who had been knighted by the British Crown for his humanitarian work, was involved in planning for the Easter Rising. He sought assistance from Germany, then at war with England, and when he arrived on the south coast of Ireland he was soon arrested, taken to England, and tried for treason. Casement was sentenced to death and executed in Pentonville Prison on August 3, 1916.
