Military operation

- Operation Felix:

Before Hendaye, there had been Spanish-German planning for an attack, from Spain, upon the British territory of Gibraltar which was, and is, a British dependency and military base. At the time, Gibraltar was important for control of the western exit from the Mediterranean and the sea routes to the Suez Canal and Middle East, as well as Atlantic patrols.
The Germans also appreciated the strategic importance of north-west Africa for bases and as a route for any future American involvement. Therefore, the plans included the occupation of the region by substantial German forces, to forestall any future Allied invasion attempt.
The plan, Operation Felix, was in detailed form before the negotiations failed at Hendaye. By March 1941, military resources were being ear-marked for Barbarossa and the Soviet Union. Operation Felix-Heinrich was an amended form of Felix that would be invoked once certain objectives in Russia had been achieved. In the event, these conditions were not fulfilled and Franco still held back from entering the war.
After the war, Field Marshal Wilhelm Keitel said: "Instead of attacking Russia, we should have strangled the British Empire by closing the Mediterranean. The first step in the operation would have been the conquest of Gibraltar. That was another great opportunity we missed." If that had succeeded, Hermann Göring proposed that Germany would "... offer Britain the right to resume peaceful traffic through the Mediterranean if she came to terms with Germany and joined us in a war against Russia".
As the war progressed and the tide turned against the Axis, the Germans planned for the event of an Allied attack through Spain. There were three successive plans, progressively less aggressive as German capability waned.
