Mid-March 1964: Directorate General of Intelligence (DGI) officer Ramon Sinobas Casado arrived in Santiago and assumed his duties as the Charge d’ Affaires. He replaced Pedro Martinez Pirez, suggesting Martinez may have been a DGI officer as well. The new officer arrived at a difficult time for the Embassy, which had lost six officers in the previous 16 months to internal turmoil and an expulsion.
In mid-August, shortly before the 1964 presidential elections, the Jorge Alessandri administration severed relations with Cuba. The Cuban Embassy closed and its entire diplomatic staff departed almost immediately. In the 1964 elections, Alessandri‘s Christian Democratic Party and its candidate, Eduardo Frei, soundly defeated Castro supporter, Salvador Allende.
