On Tuesday 15 December, Anaya flew from Buenos Aires to the main Argentine naval base at Puerto Belgrano. He travelled there to install Vice-Admiral Juan Lombardo officially as the new Chief of Naval Operations. After the ceremony, Anaya surprised Lombardo by telling him to prepare a plan for the occupation of the Falkland Islands. Lombardo later told the author Martin Middlebrook in an interview that Anaya told him to "take them but not necessarily to keep them". The conversation between Anaya and Lombardo was short and concluded with Anaya stressing the need for absolute secrecy.
