Three specially trained allied teams known as Jedburghs were inserted into Eastern Brittany in 1944 to help liberate the region from German occupation. The Jedburghs were three-man teams comprised of two officers (at least one French) and a radio operator. They received specialized guerrilla warfare training. Their mission was to advise and supply the French resistance and coordinate their efforts with the Allied invasion. The Jedburghs established contact with resistance groups and helped pave the way for France's liberation from Nazi rule.
