In 1898 America gave many benefits to Cuba, it helped modernize Cuban industry, education and medicine and expected loyalty for doing so. Cuba was angered that between 1945 and 1960 they gave more money than all of Latin America combined. At first Americans gave Castro a good assessment, but President Eisenhower's government remained suspicious about communist success. The US was further angered when Castro's nationalistic speeches became increasingly anti-American. The Revolution had severed ties between the US and Cuba, which led to the Bay of Pigs invasion later on. In March 1960 the US led a group of trained and armed Cuban exiles in what was planned to be a simple invasion. The emigres were expected to draw support from the island, and Fidel Castro and his inefficient, unstable government would collapse almost instantly. The Americans thought this would work because a similar plan was executed in Guatemala that was a terrific success. However, the Americans had miscalculated and the failure of the invasion was humiliating. Castro was much more popular than the CIA had thought, and an army American sponsored attack would actually enrage most Cubans, at the same time improving the position of the leader, Castro. This, the Americans had all misjudged. The Bay of Pigs invasion had been drawn up by President Eisenhower, but John.F.Kennedy approved the CIA plan soon after taking control. On April 17, 1400 members of Cuban exiles came from Nicaragua. They landed in the Bay of Pigs, were discovered by local milita and were forced to open fire. The crucial tactic for America was the element of surprise, and that was now gone. Fidel had actually learnt of the invasion at 3:15am that day and prepared an army and rounded up CIA agents and journalists. By the 18th, just the next day, the invasion was doomed. The brigade pleaded with Kennedy for aerial support but he declined. Defeat of the Americans came on the 19th, with 1,100 prisoners left in Cuba.
