Unsuccessful invasion because Kennedy backed out at the last moment on his pledge for air support.
Then he ransomed the POWs by using tax money to give the Castros 500 tractors which turned out to be high dollar bulldozers.
From the article below which contains 2 embed videos with the Veterans of Brigada 2506 who endorsed Donald Trump one month ago, today.
Taking the podium to chants of USA! USA!, Trump said he was humbled by this endorsement from true freedom fighters and recognized the Damas de Blanco (Ladies in White), a Cuban dissident organization composed of the wives, mothers, daughters, and sisters of political prisoners. They march quietly to church every Sunday and are subject to physical and verbal violence and abuse by government-sanctioned mobs, Trump noted, adding that Clinton turns a blind eye to the human rights violations that occur every single day.
Miamis Bay of Pigs Museum is a spiritual home for the Brigada 2506, the official name of the Cuban freedom fighters who embarked on the mission to overthrow Castro in 1961. It features a wall commemorating the martyrs killed during the operation including a number of non-Cuban American fighters as well as a variety of memorabilia from both the operation and Cuban history generally, including a collection of the flags used throughout the islands history.
Bay of Pigs veterans have nearly unanimously asserted that the mission to free Cuba failed because leftist icon president John F. Kennedy failed to provide the air support the group had been promised after the fighters had deployed. Air support was critical to the design of the military operation.
