Europe's "Stay Behind" Units
Origins of the Stay Behind Network
Information that surfaced in recent years suggests that the "Stay Behind" concept first arose in Britain. Senior military sources told the Guardian newspaper in December 1990, that a British guerrilla network was already in place following the fall of France in 1940. Numerous arm "caches" were buried for later use by a special forces ski battalion of the Scots Guards under the leadership of Brigadier "Mad Mike" Calvert. After the war, the decision was taken to create new units throughout Europe. The plan was conceived by the US Joint Chiefs of Staff and spearheaded by the newly formed CIA.
Italy was not alone in having covert "stay behind" units in operation. The operation encompassed all of western Europe. In France the unit was called "Glaive" - again named after a Gladiatorial sword. Austria's unit was named "Schwert," also meaning sword. In Turkey the unit was named "Red Sheepskin" and in Greece "Sheepskin." Sweden's unit was called "Sveaborg." In Switzerland it went by the title P26. Other units in Holland, Belgium, Spain, Portugal, Germany, Norway, Luxembourg, Denmark and Holland remain unnamed. Not least, the United Kingdom's unit was simply known as "Stay Behind."
