Lt Col Randy McCanne Operation Sea Lion: A Joint Critical Analysis

Annotation

Military history contains many lessons from which the warfighting doctrine of the individual services, as well as joint doctrine, is derived. World War II stands as one of the major contributors of valuable lessons learned. From a joint and combined warfighting perspective, Germany's planning and preparatory military actions to the invasion of Great Britain after the fall of France are instructive. Their plan, called Operation SEA LION by the Germans, was never carried out, as certain prerequisite conditions were never achieved, and Hitler elected to move on to other operations. But Germany could have been successful in invading and, if necessary, occupying Great Britain had they exercised joint and combined operations to achieve better unity of effort within the German military, remained focused on key British operational centers of gravity, and exploited the capabilities of friendly nations such as Spain, Italy, and the Vichy government of France.
