ABSTRACT
In the same month of September 1944, the international committee, as if inspired by the massacre of the Allied officers, established a military branch, responsible for the organization of combat groups and known by the acronym AMI, in its French version the Appareil militaire international. The Spanish group, which already had its own military organization headed by regular officers such as Luis Montero, 1 at once offered its services. A distinguished Italian survivor writes that no one at the time knew who the organizers were: 'Only after the Liberation did we learn that it was the Spaniards who were at the head of it. To these Spaniards all the survivors of Mauthausen owed their lives. The SS knew there was such an organization, and they did everything they could to uncover it, but they failed.' 2
