of Ireland since, under the Geneva Convention, internees were held until the end of the conflict. On 5 March 1943, in a MOST SECRET internal minute from MI9 to the Director of Intelligence, a discussion between Sir John Maffey, the British representative in Eire, and the Irish Government was reported. It concerned the possibility of faking the escape of British prisoners of war interned in the Curragh. The deal fell through, apparently because the Irish Government wanted fighter aircraft in exchange. Whether the internees might be encouraged to escape anyway was a moot point since there was the distinct possibility of political embarrassment. The fact that the General Map of Ireland was produced at all appears to bear testimony to the fact that MI9 prepared for the possibility of escape and it was certainly recorded in the War Diary that nine RAF officers escaped from the Curragh Camp in Eire on 25 June 1941. Three were recaptured and six reached England. MI9 apparently wrote a special SECRET report on the escape, but this has not been identified.

      Those sheets where surviving copies have been located in British record repositories and the various states in which the sheets were produced, either singly or in combination, are detailed in Appendix 1. A total of fifty-nine sheets have been identified in this initial group of the escape and evasion maps, of which over forty are clearly based on Bartholomew maps. Some of these carry the original Bartholomew job order number which has allowed them to be compared directly with the lithographic paper copy held in the company’s print archive now housed in the National Library of Scotland’s map collection in Edinburgh. Sixteen sheets which are believed to have been produced but for which no copies have been identified to date in British record repositories are listed in Appendix 2. This group is either noted on the print records, shown on adjacent sheets diagrams, represents gaps in the assumed consecutive numbering sequence or, in one case, has been spotted by a colleague at a map fair but no details were recorded.

      By autumn 1942, there was an increasing awareness that the small-scale maps being issued to aircrew were regarded by them as too small-scale. The need for better maps at larger scales gained momentum and ‘a new series gained approval’. It is not clear what this new series was, but it is likely to have been the fabric versions of series GSGS 3982 (see the following section), as they started to be produced at that time, their earliest print dates being the late summer and autumn of 1942. At this stage valuable information about the Swiss frontier was also being incorporated into a map of the frontier area produced at 1:100,000 scale.

      Despite the evidence indicating that MI9 engaged initially with commercial companies to develop and progress the escape and evasion mapping programme, there was clearly contact with the operational map-makers at some stage since any map series carrying a GSGS series number is immediately identifiable as an operational series. This group of escape and evasion maps was produced by reducing the original operational Europe Air series from 1:250,000 scale to 1:500,000 scale. This reduction could only have been done from the original reproduction materials which would have been held by D.Survey since, apart from their scale and print medium, they are identical in all respects to the original lithographic paper maps.

      As a result of the scale reduction, the escape and evasion maps were one quarter the size of the original operational lithographic maps printed on paper. These maps were variously referred to as ‘miniatures’ or ‘handkerchief’ maps (while no confirmation of this description has been found in the records, it carries the ring of authenticity because of the small size of the maps and their reduced scale). The sheets were printed in six colours and individual sheet coverage is two degrees of longitude (°E) and one degree of latitude (°N). All geographical values of the extent and coverage of individual sheets have been derived from an index of the original series acquired from the Defence Geographic Centre (DGC). This index has also been used as the basis of the cover diagram shown on page 61.

      Escape and evasion versions of some seventy-four sheets were produced. Over 35,000 copies were printed between 10 July 1942, when production apparently commenced, and an unrecorded day in July/August 1944, when the decision was taken to cease production. One can therefore conjecture that MI9’s contact with D.Survey, either directly or using the Ministry of Supply as an intermediary, had started at least by mid-1942. Despite the significant number of copies produced, relatively few surviving sheets have been discovered. This may reflect the fact that many of the print runs were very small, 45 and 100 being common.

      The sheets in this series were produced sometimes singly and sometimes in combination, although it has not proved possible to identify from the records the various combinations which were produced. They were produced on fabric or paper, the latter being variously described in the print record as ‘RL’, an acknowledged abbreviation for rag lithographic paper, ‘thin BANK paper’, ML (Mulberry Leaf) or MLS (Mulberry Leaf Substitute). One interesting group of a block of four of these sheets was produced under the codeword ‘Dutch Girl’. They are centred on Arnhem and are of non-standard geographical extent, location and scale, being 1 inch to 6.56 miles or approximately 1:420,000; as a result they are referred to in the record as Sections 1, 2, 3 and 4. The record shows that some 4,400 copies of these four sheets were produced in June 1942 and were described by Hutton in earlier correspondence with Waddington as ‘a very, very urgent requirement’. The purpose of producing these sheets at that stage is not clear, although it might have related to the combined operations which took place at that time and are known to have involved Section X of MI9 and the Special Operations Executive (SOE). In all probability, the subsequent printing of the same sheets, which took place in the period prior to August 1944, was in timely support of the Battle of Arnhem, otherwise referred to as Operation Market Garden, which took place in September 1944.
