 Barbier further commented that while the Germans believed the deception due to "preconceived ideas about the importance of the Pas De Calais", the Allied staff had overestimated the effectiveness of the deception after the 15th Army's inaction because they held a "preconceived notion of what FORTITUDE would accomplish".Following the Battle of Normandy, the phantom 80th Division was "transferred" around the east coast of England, moving back and forth between VII Corps and the equally bogus II Corps.The division was eventually "disbanded" in April 1945.
