During the lead up to the Allied invasion of Normandy, many new tactics in psychological warfare were devised. The plan for Operation Bodyguard set out a general strategy to mislead German high command as to the exact date and location of the invasion. Planning began in 1943 under the auspices of the London Controlling Section (LCS). A draft strategy, referred to as Plan Jael, was presented to Allied high command at the Tehran Conference. Operation Fortitude was intended to convince the Germans of a greater Allied military strength than existed, through fictional field armies, faked operations to prepare the ground for invasion and leaked information about the Allied order of battle and war plans.
