The article delves into one of the most controversial chapters of the 23-F coup attempt, focusing on the involvement of Spain's secret service, the Centro Superior de Información de la Defensa (Cesid), in the coup. Historical documents reveal that the coup plotters attributed their failure to leaving King Juan Carlos I free during the crisis, highlighting the significant role the monarchy played in countering the coup. Furthermore, it discusses the harrowing moments experienced by some central figures involved, such as Tejero's wife, who expressed her despair over the military's abandonment during the attempted coup.

As new evidence emerges from the recently declassified documents, the connection between Cesid and the coup attempt becomes increasingly clear, suggesting an orchestrated effort to conceal this involvement until now. The documents contain critical communications and orders during the coup, including the final directive to neutralize the takeover that emphasized that no coup could shield itself behind the King, thus affirming the monarchy's stance against such actions.

The implications of this revelation may reshape the understanding of the 23-F coup attempt narrative. It raises questions about the integrity of Spain’s intelligence services and their historical accountability over actions taken during one of the most critical periods in modern Spanish history. As the truth comes to light, it presents a challenge for historians and political analysts to reassess past interpretations of the events surrounding the coup and the responses of various state institutions, particularly the monarchy and military.
