Haiti, 1958 — military coup attempt

Haiti (HTI)Caribbean, AmericasJuly 28, 1958

Event Summary

On 28 to 29 July 1958 a small force of three exiled Haitian army officers and five American mercenaries, led by Captain Alix Pasquet, attempted to overthrow President Francois Duvalier by seizing the Casernes Dessalines army barracks near the National Palace in Port au Prince and rallying sympathetic troops for an assault on the palace. Pasquet, an aviator who had trained with the Tuskegee Airmen, had been exiled after Duvalier's 1957 election and organized the raid from Miami, landing by boat and bluffing his way into the barracks by claiming to deliver prisoners. But the garrison showed no enthusiasm for revolt, and when one plotter sent a captured soldier out to buy cigarettes, the soldier alerted the palace that the rebels numbered only eight.

Duvalier donned a helmet and rallied his forces, and at daybreak on 29 July the army counterattacked and killed all eight insurgents. The failed coup deepened Duvalier's distrust of the army and spurred his creation of the Tonton Macoutes militia.

Editorial Note

Date match, well documented. Distinct from the 1957 transitional churn record; this is the first of many exile coup attempts against Duvalier's consolidated rule in the dataset.

Cross-Reference

Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
