 Joseph Schmid, Jeschonnek's chief intelligence officer, was primarily responsible for providing inaccurate and distorted information to senior German air commanders encouraging enormous over-confidence.As the Battle of Britain progressed Jeschonnek, Göring and Kesselring came to believe the overly optimistic victory reports by German airmen and the false intelligence from Schmid suggesting RAF Fighter Command was on the verge of collapse.The intelligence was a factor in encouraging Göring to shift the air effort to London on 7 September, in a move to bring the last of Fighter Command's into battle.
