William Alexander Morgan was an American-born Cuban guerrilla commander who fought in the Cuban Revolution, leading a band of rebels that drove the Cuban army from key positions in the central mountains as part of Second National Front of Escambray, thereby helping to pave the way for Fidel Castro's forces to secure victory. Morgan was one of about two dozen U.S. citizens to fight in the revolution and one of only three foreign nationals to hold the rank of comandante in the rebel forces. In the years after the revolution, Morgan became disenchanted with Castro's turn to communism and he became one of the leaders of the CIA-supplied Escambray rebellion. In 1961, he was arrested by the Cuban government and, after a military trial, executed by firing squad in the presence of Fidel and Raúl Castro.

Eloy Gutiérrez Menoyo was a revolutionary who led the guerrilla force Second National Front of Escambray during the Cuban Revolution against Fulgencio Batista and later opposed the government of Fidel Castro over its pro-Soviet leanings. His brother Carlos Gutiérrez Menoyo died in the Presidential Palace attack of March 13, 1957.
