This article is devoted to the efforts of Francoist Spain to ensure the defense of the Canary Archipelago in 1940–1942. The obviousness of British plans to conquer Macaronesia forced the Spaniards to take measures to preserve sovereignty over the islands. The goal was achieved in conditions of resource scarcity and the threat of a naval blockade. In this situation, the leadership of the defense resorted to emergency measures. A partial mobilization of people and resources was carried out on the archipelago.
