What was the performance of the Joint Chiefs of Staff and Department of Defense during the execution of the Bay of Pigs?

The performance of the Joint Chiefs of Staff and the Department of Defense during the Bay of Pigs invasion in April 1961 was widely criticized for its lack of effective planning and execution. The military's assumptions about popular support in Cuba and the feasibility of air support proved to be flawed, leading to a rapid failure of the operation. The invasion faced unexpected resistance from Cuban forces, and the failure highlighted significant issues in communication and coordination within the U.S. government and military leadership. Ultimately, the operation was a major embarrassment for the Kennedy administration and led to a reevaluation of U.S. covert operations.
