9:31 PM, May 7, 1973

The cable was dispatched at the highest urgency level available to American diplomats: Night Action Immediate, requiring attention regardless of the hour. It ran to three paragraphs. The Embassy sent it while the shooting was still audible across the city.

What the Embassy knew at that hour

Fighting had broken out around 10:00 PM local time on the outskirts of Beirut, with the most serious engagement in the area of Shatila refugee camp. A large number of rockets had been fired across the city. Some, the Embassy reported, had been directed at the airport — one of Lebanon's most strategically and economically vital installations. Others had landed near the Military Governorate of Beirut, the headquarters of the army's authority over the capital. Still others had been reported in the general vicinity of the Presidency — the seat of Lebanon's head of state.

The simultaneous targeting of these three nodes — the airport, the military command, the Presidency — was not random. The cable does not say this explicitly, but the pattern it documents implies coordination.

The Army's verdict, that night

In brief contacts with a Presidency aide named Dib and an Army officer named Kanaan, the Embassy obtained one assessment that stands out. Kanaan told the Embassy that the Lebanese government considered the situation "not dangerous but very serious" — and that Lebanese officials were "especially concerned at deliberate, widespread efforts to prevent GOL-fedayeen relations from stabilizing."

Then: the Syrian government, Kanaan said, "appears to be playing the most unhelpful role in this regard." He had no time to elaborate.

This attribution — Syria identified as the most disruptive external actor, on record, at the moment the crisis was unfolding — appears in no standard account of the May 1973 events. It is documented in this cable, filed before midnight on May 7, 1973.

The limits of the moment

The cable is honest about what it does not know. The Embassy's information is "extremely spotty." The government's information, Houghton notes, is also extremely spotty. The cable closes with a direct acknowledgment: "We will report further when we are able to obtain a clearer picture of the situation."

That clearer picture arrived in two cables filed the following morning. Cable 1973BEIRUT05159, dispatched at 8:08 AM on May 8, reported that the Lebanese Army had by then expended aircraft and tank fire against Sabra/Chatila, Bir Hassan, and Borj el Brajne camps. The Prime Minister had resigned at 5:00 AM. A ceasefire came into effect at 8:00 AM. And the Army's G-2 named the specific Palestinian factions responsible for the night's fighting: PDFLP, PFLP/GC, and possibly Sa'iqa — precisely the Syrian-aligned factions Kanaan had pointed toward the night before without being able to say more.
