10 Pesos 40th Anniversary of Landing of the Granma

The Granma — a leaking, overloaded American-built yacht — carried Fidel Castro, Che Guevara, and 80 other fighters from Tampico, Mexico, to the Oriente coast in December 1956. The landing was a near-disaster: the boat ran aground in a mangrove swamp two days late, the element of surprise was lost, and Batista's forces killed or captured most of the expeditionaries within days. Of the 82 men aboard, fewer than 20 regrouped in the Sierra Maestra.

Cuba named its official Communist Party newspaper after the vessel in 1965.
