Operation Felix

During World War II, Felix was the proposed name for a German/Spanish seizure of Gibraltar. It was scheduled for 10 January, 1941 but never executed. This plan was discussed at a meeting held between Franco and Hitler in late October, 1940 in Hitler’s railroad car at Hendaye. Hitler later said he would rather have three teeth extracted that to meet with Franco again.

It is subject to historical debate if Franco overplayed his hand demanding too much from Hitler for Spanish entry into the war, or if he deliberately stymied the German dictator.
