In August, Colonel John Henry Bevan, head of the London Controlling Section, presented a draft plan. Codenamed Jael, a reference to the Old Testament heroine who killed an enemy commander by deception, it would have attempted to deceive the Germans into thinking that the Allies had delayed the invasion for a further year but instead concentrated on the Balkan theatre and on air bombardment of Germany through 1944. The plan had a mixed reception in the Allied High command, and in October, a decision on the draft was deferred until after the Tehran Conference, a month later.
