The Spanish airlift of 1936 was a military operation, carried out by the Nationalists during the early phase of the Spanish Civil War. It did not have any specific code name. Its objective was to bypass the Republican naval blockade of the Strait of Gibraltar and transport by air the soldiers stationed in the Spanish Morocco to the rebel-controlled part of Andalusia. The undertaking was hugely successful; during 85 days between July 19 and October 11 the Nationalists transported at least 14,000 men and at least 270 tons of war materiel. The success was possible thanks to German and Italian assistance, as aircraft sent by Hitler and Mussolini carried most of the troops and equipment. The operation is viewed as innovative, as it was the first ever large-scale military transport by air. Since there was no major Republican counter-action, the airlift was a challenge in terms of logistics and technology rather than combat. The opinion prevailing in historiography is that the airlift was vital for the Nationalists and helped to turn the failed coup into a long-lasting civil war.
