A woman walks beside a billboard in the village of Palpite in the Zapata swamp near the Bay of Pigs April 8, 2012. On April 17, 1961, a force of CIA-trained Cuban exiles, backed by U.S. ships and planes, came ashore at the Bay of Pigs 100 miles (160 km) southeast of Havana in a bloody attempt to spark a counter-revolution. Cuban leader Fidel Castro rallied tens of thousands of troops and citizens to the battle and two days later, on April 19, 1961, declared victory as the attackers fled or were killed or captured in the botched invasion. Billboard reads "The mercenaries reached to this point". Picture taken April 8, 2012. REUTERS/Desmond Boylan (CUBA - Tags: SOCIETY ANNIVERSARY MILITARY POLITICS)
