Cuba, 1957 — military coup attempt
Event Summary
On 5 September 1957 junior officers of the Cuban Navy at the Cienfuegos naval base rose against the government of President Fulgencio Batista, in a revolt organized in sympathy with the 26th of July Movement and originally meant to coincide with the seizure of warships in Havana harbor. The rising seized the base by early morning, and its roughly fifty original conspirators were joined by the base's 150 naval personnel and some two hundred armed 26th of July Movement supporters from the town, holding Cienfuegos for several hours. But the Havana part of the plot failed to materialize, leaving the Cienfuegos rebels isolated.
Government motorized infantry arrived from Santa Clara backed by American-supplied B-26 bombers, and after heavy fighting that killed more than a hundred people the revolt was crushed. Batista survived, and the navy was purged, but the uprising demonstrated the spread of anti-Batista sentiment into the armed forces.
