b. Shortly after this the units intended for use in Spain will cross the Franco-Spanish frontier on land or in the air.
Section III
a. Attack for the seizure of Gibraltar by German troops.
b. Mobilization of troops to march into Portugal should the British gain a foothold there. The units intended for this will march into Spain immediately after the units intended for Gibraltar.
Section IV
Support by the Spanish in closing the Straits after the seizure of the Rock from the Spanish-Moroccan side as well, if required.
As for the strength of the units to be used for operation "Felix" the following will apply:
Army. The units intended for Gibraltar must be in sufficient strength to seize the Rock even without Spanish assistance.
Apart from this, a smaller group must be available to aid the Spaniards in the unlikely event of the British attempting to land at a different point on the coast. The units to be kept in readiness for a possible invasion of Portugal are to be predominately of a mobile nature.
Air Force. Sufficient forces will be detailed for the air attack on Gibraltar to guarantee substantial success.
