I found this obscure operation from WWII very interesting, since I know an individual linked to it.
This synopsis was taken from Wikipedia (Click image to see full article).
The operation took its name, probably assigned at random from a list of pre-approved code names, from the town of Jedburg in the Scottish Borders. After about two weeks of paramilitary training at commando training bases in the Scottish Highlands, the “Jeds” moved to Milton Hall, which was much closer to the airfields from which they were to be launched, and to London and Special Force Headquarters.
Operation Jedburgh represented the first real cooperation in Europe between SOE and the Special Operations branch of OSS. By this period in the war, SOE had insufficient resources to mount the huge operation on its own; for example, it had access to only 23 Handley Page Halifax aircraft for dropping agents and stores, barely sufficient to maintain SOE’s existing networks. OSS was able to augment this force with Consolidated B-24 Liberator aircraft operating from RAF Harrington (which they codenamed “Carpetbagger”). The OSS eagerly sought to be involved, since in a single swoop it got more agents into northwestern Europe than it had during the entire previous period of the United States’ involvement in the war. Nevertheless, General Eisenhower, the American Supreme Commander, ensured that the French would lead the operation and gave them command on 9 June, 1944 of the Jedburgh teams in France.
