An original sketch-map in Roger Casement's hand, showing the location of items he and his companions had hidden after landing from the German U-boat U-19 on Banna Strand, County Kerry on Good Friday, 1916. Two facing pages 8vo, on blind-stamped paper of the Metropolitan Police Office (Scotland Yard), with Casement's directions to the cache ('Under some fern bracken & bramble in the moat...'). The only things mentioned are '1 pair Binoculars' and '1 Lamp; the words '?50 in gold & silver' may be in a different hand, probably that of one of his interrogators, Major (later Colonel) Frank Hall. With contemporary envelope in Hall's hand; 'Plan of RATH drawn by Roger Casement at Scotland Yard when first interrogated on Easter Sunday 1916. Present B[asil] T[homson]/Herschell/Self. FH'. Accompanying Casement's map is a later note written in ink by Frank Hall on a small slip, which gives details of the distribution of the cache after it had been retrieved. It is known that three Mauser pistols had been discovered when Casement was arrested in Ireland, and F E Smithin his account of the trial of Casement has it that 'Bailey buried there some weapons, some maps of Ireland of foreign origin and three coats, one of which contained Casement's diary', but this documents gives a fuller pictuire. 'His binoculars were given to Basil Thomas/Gold sleeve links to DI Cheesman/'Flag of Irish republic' to R I C mess Phoenix Park/Cash to Sgt. & Constable R I C/3 mauser pistols to me. I gave one to [Major Ivor] Price who used it at Connie Marciewitz [sic] at the Castle & missed her' and a copy of the Easter Rising surrender document given to Frank Hall by E W Pearson
