Signal Corps (French Army)

After early developments 1793–1899, first specifically signals units were formed circa 1900 as part of the Engineers. The experience of the Battle of France showed that signals units being under the aegis of the Engineers did no longer allow for fully effective communications. As a result, on 1 June 1942, by Ministerial Decree no 3600/EMA/1 of 4 May 1942, Transmissions became a distinct arm, as part of the Armistice Army (of Vichy France).
