Two Allied operations during World War II were codenamed Ratweek:
A co-ordinated assassination offensive against Nazi security forces in Occupied Europe was mounted in January 1944 by the Special Operations Executive (SOE), whose intention was to create confusion and trepidation at the same time as the Allies increased preparations for the Resistance's contribution to the Normandy Landings. Full details have never been released, but it is known that "Ratweek" achieved successes against Nazi personnel and collaborators in Norway, France, Denmark, and the Netherlands.[1] In 2000 it was revealed that the operation had been supervised by Edwin Hardy Amies, at the time head of the SOE's Belgian Section.[2]
Within the Balkans, Ratweek was a series of coordinated attacks on the Axis lines of communication - principally the railways. It was launched on 1 September 1944 by Yugoslav partisans, the combined operations units of Land Forces Adriatic, the heavy bombers of the 15th Air Force heavy bombers and the light and medium bombers of the Balkan Air Force. The attacks paralysed movement of the German forces.[3] In his memoir Eastern Approaches, Fitzroy Maclean claims this was his idea.
