As taken from a chat I had to give other users the answer as well.
The United State was involved in the Bay of Pigs invasion in that the Central Intelligence Agency, an arm of the Executive branch, was funding and training the Cuban rebels and sent them into Cuba at the Bay of Pigs to overthrow the communist government led by Fidel Castro.
Castro's army found out about the invasion and met the rebels at the beach, capturing or killing many.
Your answer is B she led them to freedom via underground railroad
