The letter is a facsimile copy of a letter written by Sir Roger Casement (1864-1916). In the letter, Casement mentions that he will be going to Berlin. He also refers to a letter to 'H' and to 'other contacts'. Presumably with a view to secrecy, names and places are not missing from the letter.Sir Roger Casement was a humanitarian and Irish Nationalist. Casement believed that an Irish insurrection would be crushed unless it received substantial assistance from Germany. He spent eighteen months in Germany, arriving first as an envoy of Irish-American leaders, attempting to encourage Germany to support Irish separatist aspirations by providing arms. Casement succeeded in securing limited German support but his attempt to form a brigade of Irish soldiers in German prisoner of war camps to fight against Britain was largely unsuccessful. When it became clear that adequate help would not be forthcoming he travelled to Ireland by submarine. Casement landed and was arrested at Banna Strand, County Kerry on Good Friday 1916. He was tried in the Old Bailey for treason and subsequently executed by hanging at Pentonville Prison on 3 August 1916.
