Map, Silk, Escape, MI.9.
Rare WWII genuine British one-sided silk escape map. This is one of the earliest series of silk escape maps produced by Bartholomew of Edinburgh on behalf of M.I.9.
On one side of this cloth is a map of Germany and eastern Europe showing the international frontiers as they were in 1941. It has the sheet identity number 9.U.
To prevent the cloth from unravelling, the map was heat treated to prevent the ravelling.
Maps were issued to aircrew of the RAF and USAAF as part of an escape kit in case they were shot down or forced to land while on a mission to Occupied Europe.
Escape maps were believed to be one of the most useful items in an airman's escape kit. They were useful to those engaged in resistance work helping Allied servicemen to evade capture and eventually return to Britain and continue the fight.
The information regarding the Bartholomew maps was derived from the 76 page bound top-secret booklet by Christopher Hutton, Per Ardua Libertas (Published on February 14, 1942), which was a publication of MI.9 that was given to American intelligence officers when they visited England in 1942 to commemorate their visit.
