'Dunton' was an Allied deception plan associated with 'Diadem' via 'Zeppelin' (i) (April 1944).

The plan was posited on trying to persuade the Germans that the US Army was preparing to ship an entire division to the Mediterranean theatre directly from the USA in two converted liners, the 43,153-ton Ile de France and 36,287-ton Nieuw Amsterdam, which were currently lying idle, and thereby pressure the Germans into maintaining in southern Europe forces which might otherwise have been deployed to North-West Europe, where 'Overlord' was shortly to be launched.
