October 1973: According to the Defense Intelligence Agency (DIA), by 1973 the Cuban presence had ballooned to over 1000 personnel, with roughly 250 at the Embassy and the rest spread throughout the Chilean government bureaucracy as advisors. The Cubans were active and aware of the threat to the Salvador Allende government. However, Havana’s warnings and offers of military aid were rejected. DIA further reported that by that October, an average of 60-70 Cuban officials were constantly travelling between Havana and Santiago. The Pentagon spy agency also noted that the Cuban officials were exempt from Chilean immigration and customs inspections.
