Ironside was implemented entirely via double agents: "Tate", "Bronx" and "Garbo". The Twenty Committee, in charge of anti-espionage and deception operations of British military intelligence, feared the plausibility of the story and so did not promote it too heavily through their agents. Messages sent to their German handlers included elements of uncertainty. That, combined with the fact that Bordeaux was an implausible target (the landing site was far outside the range of fighter cover from the United Kingdom), meant that the Germans took very little notice of the rumours and even went as far as to identify it as a probable deception. However, the Abwehr continued to send questions to their agents related to the landings until early June, and after D-Day, the Germans continued to maintain a state of readiness in the region.
