October 21, 1963: In 1963, a CIA-sponsored group called Commandos Mambises began minor surgical strikes, called mosquito attacks, against Cuba. On this date, the Mambises attempted to rendezvous with two commandos who had infiltrated near Cabo Corrientes a week earlier. However, Cuban Intelligence had learned of their mission and Havana’s military forces set a trap. Two Mambises were killed, one wounded, and four others captured. The Cuban Air Force attempted to attack the Commando’s vessel, but mistakenly attacked a Liberian freighter. Cuban Intelligence continued to track the Mambises, which enabled Castro to hold a news conference a few days later and announce that the Mambises’ ship, known as the Rex, was a CIA vessel docked in West Palm Beach.
