The German naval strategy for the Atlantic islands between 1940 and 1943

Although the strategic value of the Spanish and Portuguese Atlantic islands for the Third Reich during the Second World War has been the subject of several studies, certain issues remain unknown. One is the link between the strategic re-evaluation of these islands and Spain and Portugal's neutrality. The other is the role of the different Atlantic archipelagos in the German strategy after 1940. To respond to these questions, the author consulted primary sources in the Bundesarchiv-Militärarchiv and other archives elsewhere, as well as the most relevant bibliographical references. Worth highlighting among the conclusions is that the Spanish policy of non-belligerence significantly influenced German interests concerning the Atlantic islands during both the summer and autumn of 1940, as well as in later periods during the conflict.
