So we all know that Operation Paperclip was the American OSS operation that captured and brought to America many of Nazi Germany's top scientists and their work, prominent amongst them being Werner von Braun, who was rehabilitated to such an extent that he's considered an American hero these days. The Soviet Union also had a similar project which provided them with some of the knowledge for their space programme. What I'm curious about was whether the United Kingdom had a project of their own for if they encountered any German scientists or was there no organised effort as the British expected the Americans to share any knowledge they gained, much as they had with the Atomic Bomb project? The British Second Army advanced across much of North-West Germany during the closing stages of the war, capturing Himmler amongst others, so they would have had ample opportunity to do such intelligence gathering.
The Brits were part of the Alsos Mission, in turn part of the Manhattan Project. Alsos personnel recovered much of the German atomic weapons program records and equipment, and took most of the senior German research personnel into custody. It includes the British-run Operation Epsilon.
There was the British [Operation Backfire](http://en.wikipedia.org/wiki/Operation_Backfire_(WWII), which recovered some V2 rockets. Handling and launch procedures were unknown, so the Brits hand German personnel perform these. During and after the launches, the British attempted to recruit German personnel, even those transferred from US custody and due to be returned, to assist with their own missile program.
There was Operation Surgeon, a British post-Second World War program to exploit German aeronautics and deny German technical skills to the Soviet Union. A list of 1,500 German scientists and technicians was drawn up, to forcibly remove them "whether they liked it or not" to lessen the risk of them falling into enemy hands.
And then there's the British/American T-Force, which went after industrial plants and their key personnel and documents.
In post war Germany, T-Force was tasked with carrying out abductions of German scientists and businessmen. One of the objectives of these abductions was to recover military secrets of Nazi Germany. In addition to this, the abductions of the scientists enabled Britain to use their knowledge in building up the British economy after the war, and also prevented the Soviet Union from obtaining their knowledge. The knowledge obtained from businessmen and technicians was used to improve British industries.
While it was "post-war" for Germany, the information was still important for use in the still-running war in Asia.
These operations weren't just about keeping the technology away from the Soviets:
Alsos Mission: "In December 1943, the Alsos Mission reached Algiers, where Pash reported to the Chief of Staff at Allied Forces Headquarters (AFHQ), Major General Walter B. Smith, and his British Chief of Intelligence, Brigadier Kenneth Strong. This was awkward as Pash's instructions were not to give the British information about the Alsos Mission, although, as it turned out, Strong was already fully aware of it."
Operation Big: "Worried that French forces might beat the US to Werner Heisenberg's laboratory..."
