Indeed. The SBS started to come into the game around the German occupied ports of W and SW France and the like around the same time. Mainly sabotage and stuff. The cockleshell heroes were typical of that type of attack (they were essentially commandos but became the SBS). The cockleshells were the subject of a great 1955 film and a recent documentary which I would rate as one the best I've ever seen.I believe so. But that’s who the SAS went on to assist.
