Home Army intelligence provided the Allies with information on German concentration camps and the Holocaust in Poland (including the first reports on this subject received by the Allies), German submarine operations, and, most famously, the V-1 flying bomb and V-2 rocket. In one Project Big Ben mission (Operation Wildhorn III; Polish cryptonym, "Most III", "Bridge III"), a stripped-for-lightness RAF twin-engine Dakota flew from Brindisi, Italy, to an abandoned German airfield in Poland to pick up intelligence prepared by Polish aircraft-designer Antoni Kocjan, including of V-2 rocket wreckage from a Peenemünde launch, a "Special Report 1/R, no. 242", photographs, eight key V-2 parts, and drawings of the wreckage. Polish agents also provided reports on the German war production, morale, and troop movements. The Polish intelligence network extended beyond Poland and even beyond Europe: for example, the intelligence network organized by Mieczysław Zygfryd Słowikowski in North Africa has been described as "the only llied ... network in North Africa". The Polish network even had two agents in the German high command itself.
