Operation Periwig was a secret service operation planned and carried out by the British Special Operations Executive (SOE) from November 1944 onwards during the Second World War. The aim was to disrupt the Nazi regime by feigning resistance movements within the German territory. In order to draw attention to the alleged resistance movement in Germany, suitable deceptive measures were devised. For example, containers with weapons, ammunition, propaganda material, food and the like were to be dropped by aeroplane over imaginary supply points of the ostensible resistance movement.
