A Navy Sitrep from the Heart of the Coup
On 1 October 1973 the U.S. Navy section of the United Nations Military Group in Chile filed its second Situation Report (SITREP) on the September 11 overthrow of President Salvador Allende. The memo was written by a small team of American naval officers stationed in Valparaíso, a coastal city that escaped the fiercest fighting but remained a hub for U.S. diplomatic and intelligence activity. Their report was not a formal intelligence assessment; it was a field‑level chronicle of what the writers perceived as the “dead‑end” conditions that drove the Chilean armed forces to act, and a day‑by‑day log of their own attempts to protect American families amid the chaos.
The document emerged in the immediate aftermath of the coup, a period when Washington was scrambling to gauge the scope of the new regime, assess the safety of its personnel, and decide whether to intervene more directly. The Navy’s “Sitrep #2” follows a February 1973 dispatch that warned of a revolutionary tinderbox, and it treats the September events as the inevitable conclusion of a long‑running crisis. The language is strikingly deterministic: the authors describe the Allende government as a “three‑year experiment in Marxism” whose failure was sealed by inflation, strikes, Cuban‑supplied arms, and “saboteurs” infiltrating the military. This rhetoric mirrors the broader U.S. narrative that framed Allende’s socialist experiment as a threat to regional stability and a potential foothold for Soviet influence.
The Coup in Context
The September 11 coup was the climax of a volatile Cold‑War showdown in Latin America. After the 1970 election of Allende, the United States, under Nixon and later Ford, authorized covert actions—most famously the CIA’s Project FUBELT (also known as “Track II”)—to destabilize the Chilean government through economic pressure, propaganda, and support for opposition groups. By mid‑1973 the Chilean economy was indeed in free‑fall, but the extent of U.S. economic sabotage, including the withdrawal of credit and the “Coordinating Committee for Economic Warfare,” contributed to the dire conditions cited in the SITREP. The document’s emphasis on “Cuban weapons” and “world Marxism” reflects the conflation of domestic unrest with external communist subversion that drove Washington’s policy.
The report also illuminates the internal dynamics of the Chilean military. It repeatedly stresses the “reluctance” of the armed forces, a trope that appears in U.S. diplomatic cables of the time to justify later support for the junta. By portraying the coup as a last resort forced by a “dead‑end street,” the authors implicitly legitimize the subsequent repression, suggesting that the military’s decision was a tragic but necessary act rather than a pre‑planned power grab.
What the Navy Officers Reveal
The SITREP’s most vivid passages are the on‑the‑ground observations of the Valparaíso team. Their account of “hammering on the front door” by retired officer Ignacio Iturriaga at 06:30, the hurried instructions to keep U.S. families “undercover,” and the improvisational radio link to the Panama Canal Zone convey a sense of operational improvisation. The writers note that roadblocks were manned by “nervous young soldiers/sailors” with weapons “off safe,” hinting at a lack of discipline and the ad‑hoc nature of the coup’s execution.
The report’s internal chronology—detailing the timing of Allende’s broadcasts, the delayed “H‑hour” in Santiago, and the eventual silencing of his voice by an Air Force rocket—provides a rare, contemporaneous timeline that corroborates later historical reconstructions. The authors’ frustration that the coup’s “script” slipped in Santiago underscores the decentralized character of the operation: while the navy in Valparaíso could follow a timetable, the army in the capital deviated, allowing Allende a brief window to appeal to workers before being overwhelmed.
Legacy of the Document
Declassified in 2017 as part of the “Chile: Secrets of State” collection, this SITREP offers scholars a granular view of how low‑level U.S. military personnel interpreted and reported a seismic political rupture. It bridges the gap between high‑level policy memos and the lived experience of American expatriates caught in a foreign coup. The document’s language—laden with Cold‑War metaphors and moral judgments—reveals how deeply the anti‑communist paradigm colored even routine field reports.
In contemporary debates over U.S. interventionism, the Sitrep serves as a reminder that official narratives often begin at the periphery, where officers translate macro‑political anxieties into daily actions: warning families, securing radio channels, and documenting the “inevitable” collapse of a leftist government. Its release enriches the historiography of the 1973 Chilean coup by adding a frontline perspective that both confirms and complicates the picture drawn from CIA files, diplomatic cables, and Chilean testimonies.
Why It Still Matters
Understanding the mindset of the U.S. Navy officers in Valparaíso helps explain how the United States rationalized its tacit endorsement of Pinochet’s regime for decades. The SITREP’s portrayal of the Allende administration as a self‑destructive experiment provided moral cover for subsequent U.S. aid to the junta, even as reports of human rights abuses mounted. By exposing the assumptions embedded in this seemingly mundane field report, historians can better trace the chain of justification that linked Cold‑War paranoia to the tragic repression that followed the September 11 coup.

1 October 1973
SITREP #2: VALPARAISO, CHILE
SITREP #1 dated 26 February 1973 reported "Chile is a revolution looking for a place to happen ... elastic of people's patience will snap with a bang!" Prediction became reality on 11 September. On that day of destiny for Chile, the Armed Forces and National Police, acting in close coordination, staged a coup d'etat against President Allende's Marxist Government. Less than eight hours after the initiation of the coup, Allende was dead and a three year experiment in Marxism joined him in the grave. There are few mourners for Allende or Marxism visible in Chile today.
DEAD END STREET
The Armed Forces decision to forcefully remove the Allende Government from power was made with extreme reluctance and only after the deepest soul-searching by all concerned. Even to we sideline observers, it was obvious the Chilean military were extremely reluctant to destroy over 100 years of prideful tradition in support of their country's constitution without exhausting every other avenue of solution. Unfortunately there were no other avenues of solution. Chile was on a dead end street. Their rate of inflation was the worst in the history of the world, terrorists and weapons were being illegally introduced into Chile by the CUBANS for USE AGAINST CHILEANS, food resources were near total exhaustion, a nationwide transportation strike had paralyzed the country, numerous other professions were striking in sympathy with the transportation workers, the Armed Forces had been systematically infiltrated by saboteurs who carried not patriotism for Chile in their hearts, but rather fidelity to world Marxism, Chile's children had not been to school for over two months ... and so goes the incredible litany of tragedy that was Chile under Allende's Marxism. What perhaps history will ask in retrospect, is not "Why the overthrow of the Allende Government by the Armed Forces", but rather "Why the Armed Forces waited so long?"
D-DAY 11 SEPTEMBER; H-HOUR 0600
Our D-day started with a foreboding 0630 hammering on the front door by Ignacio Iturriaga, a retired ranking officer and very close friend, who was later identified as one of the key local planners in the coup de etat. His arrival at 0630 was ominous in itself, in that Chileans generally start the work day at mas o menos 0900, usually more "mas" than "menos". Ignacio proudly announced the long expected D-day had arrived and that H-hour had gone at 0600 throughout the country. (His report later proved absolutely correct, with one crucial exception - the capital city of Santiago.) Ignacio recommended all U.S. personnel stay undercover, asked for our prayers and then rushed off to carry out his duties. The hour was 0635. [ < ]
AN PAUL REVERE
, first responsibility was to warn the other U.S. families in Vina to stay undercover and secondly, if possible, get an advisory type radio message off to the Panama Canal from whence evacuation help for U.S. dependents would come if deemed necessary by the U.S. Ambassador. Moving about the city even in military uniform, driving a diplomatic auto and flashing a Chilean Navy I.D. card wasn't easy. Roadblocks had been established at all key intersections, most were manned by nervous young soldiers/sailors with semi-automatic weapons, round in chamber and weapon OFF safe. They had been briefed to expect a violent combat reaction from Marxists forces and itchy trigger fingers were the rule rather than the exception. In my appointed rounds I used back alleys and side streets where possible - where not, maximum discretion coupled with an extremely friendly "Buenos Dias" in my best Irish brogue, managed to reach all but one American family before Russian Roulette game with roadblocks ran out of luck. Apparently final roadblock didn't "speak" my Irish-Spanish. However, I clearly understood their pointed signals with Grosse Guns, which in any language translated into: "Get going, Gringo". The hour was 0710.
BEGINNING OF THE END
With Navy Chief Yeoman Paul Appleby manning the radio and Lieutenant Commander Roger Frauenfelder drafting the message, we were able to communicate our local crisis to higher headquarters in the Panama Canal Zone. Reference to the situation in Santiago was specifically avoided as that estimate would have been only guesswork. Somewhat ironically, our SITREP arrived in Panama at approximately the same time President Allende was alerted in Santiago. For U.S. military authorities in Panama it was an extremely interesting report from their perennial hotspot in South America. For President Allende, it was the beginning of the end of his life. The hour was 0730.
ISSUE IN DOUBT
Chile's coup de etat was close to perfect. Unfortunately, "close" only counts in horseshoes and hand grenades; consequently there were problems. H-hour was set in covert communiqués for 0600, but as often happens in such people-controlled operations, someone doesn't follow the script. For reasons too labyrinth to explain here, H-hour in Santiago was slipped to 0830.
Original plan called for President Allende to be held incommunicado in his home until the coup was a fait accompli. H-hour delay in Santiago permitted Allende to be alerted at 0730. Allende immediately dashed to the Moneda (palace) under escort of a heavily armed personal security force, Grupo de Amigos Personales (GAP). At the Moneda he had access to radio communications facilities which permitted him to personally implore "workers and students, come to the Moneda and defend your Government against the Armed Forces". The hour was 0830.
Allende's hope was to surround the Moneda with thousands of Chilean students and workers on the supposition the Armed Forces would not shoot their way past unarmed citizens. A somewhat similar ploy had worked during the
2
The coup "rehearsal" on 29 June 1973. It didn't work this time. Army had all roads to Santiago blocked. All was on TIGRE inside city. Those on streets not wearing right color jersey stood an excellent chance of getting shot.
Allende managed to personally broadcast two "MAYDAY" type messages. The first, at 0630, sounded strong and confident as he summoned the workers and students. The second at 0945 sounded morose, almost as if he was preparing the eulogy for his dying government. It was his last broadcast as the Air Force soon located and reoriented his antenna. The hour was 1015.
MONDA UNLAI SELIG
With the voice of Allende silenced by Air Force rockets, the success of the coup de etat was 95% assured. Considering that the military was in absolute control of all Santiago and the Moneda surrounded by troops and tanks, capturing the remaining 5% should have been easy. It was not. Ground troops attempting to close on the Moneda were repulsed by GAP snipers and semi-automatic weapon fire. For the GAP there was no tomorrow and they fought accordingly. During this phase Allende attempted twice to physically contact and negotiate the Government's surrender with the attacking troops' commander. He was fired at each time by his O/N SHIPMISH! Whether they wanted to kill him for attempting to negotiate or merely prevent his negotiating is problematic. The hour was 1115.
HIGH NOON AT THE MONEDA
Facing the tenacious resistance of the GAP defenders firing from the parapets of the fortress-like Moneda, the Armed Forces reluctantly called for supporting arms. Tanks moved in rapidly, firing their heavy machine guns and silenced all but the most protected positions. A follow on pinpoint rocket attack by the Air Force finished the job. Ground troops moved in rapidly under the cover of tank fire and secured the outer perimeter of the Moneda. The hour was 1200.
The next significant objective was the main inner courtyard, which when captured would provide access to all offices located there - in particular, the Office of the President. Resistance was still stubborn inside the Moneda as the troops and the GAP fought from room to room and corridor to corridor. At 1330 an air strike was called on the inner courtyard. Once again the rockets hit with pinpoint accuracy. The inner courtyard was secured. The hour was 1335.
END. FIDEL WITH LOVE
Allende was found slain and dead in his office off the inner courtyard. He had killed himself by placing a sub-machine gun under his chin and pulling the trigger. Messy, but efficient. The gun was lying near his body. A gold metal plate imbedded in the stock was inscribed "To my good friend Salvador Allende from Fidel Castro". Obviously Communist Cuba had sent one too many guns to Chile for their own good. The hour was 1445.
LAW IN EFFECT
Though the coup is three weeks old we still live under martial law as the armed forces continue to pursue known terrorist groups and search for weapons caches. Curfew is from 1500 to 0700 without exception. Things were relatively quiet, as coups go, in Vina del Mar on 11 September; however, on 15 September at 2300 our turn on the firing line came. A terrorist group wearing stolen Chilean Army uniforms made hit and run type attacks on a police headquarters, hospital, and army barracks. Our home is located between the police headquarters and the hospital; consequently, we received a double dose of the action. There was enough machine gun fire and hand grenades to ring in the nearby streets during the forty-five minute battle to satisfy even the most rabid John Wayne movie fans. All has been quiet for the past few days, but the real test will come when the curfew is lifted. We're keeping our fingers crossed.
THE FUTURE
The Chilean armed forces are acutely aware that their responsibilities did not terminate with the fall of the Marxist Government, but rather that they have just begun. The road back for Chile will be long and hard. Their pitiful legacy from Marxism included, inter alia, a near bankrupt treasury and disastrous shortages of food and other consumer goods, which will take years to normalize. But normalize they will, because although their people were tired of strife and misery, they were not tired of their spirit. During the three years Marxist experiment in Chile, the constant rally cry of all anti-Marxists was, "Chile es, y sera, un pais en libertad" - "Chile is, and will always be, a country in liberty". Now that they are in fact again a "country in liberty" no obstacle is too high, no problem too difficult to solve. Their progress may be slow, but it will be as free men aspiring to goals which are for the benefit of Chile and not self-serving world Marxism.
