Part of the problem was that Bordeaux may not have appeared a plausible Allied target because it was out of range of fighter aircraft cover from the United Kingdom. Historian Terry Crowdy's analysis is that Ironside may have suffered simply from lack of resources. In common with other, higher-impact, Bodyguard deceptions it preyed on a concern that the Allies knew Hitler and the German High Command had discussed. Crowdy suggests that with physical deception, and more effort, Ironside could have succeeded in the same way as deceptions aimed against Calais, Normandy and the Mediterranean.
