Operation Ilona

(girl's name)

'Ilona' was a German scaled-down version of 'Isabella' (i), later renamed 'Gisela' (i), for an invasion of Spain (29 May 1942 onward).

The plan was to be invoked whether or not Spain remained neutral in the event of a British amphibious landing on the Iberian peninsula, and was posited on the seizure of the passes over the Pyrenees mountains and an advance by a force of 10 divisions to Barcelona and, if necessary to force Spain’s acquiescence or capitulation, Salamanca.
