Did the Bay of Pigs Attack Go Off Track Because It Was Supposed to Kick Off With The Assassination of Fidel Castro?

I've just finished reading Seymour
Hersh's very interesting book The
Dark Side of Camelot. He argues that the Bay of Pigs invasion went wrong in part
because Castro was supposed to be killed by the time it started. When that
didn't happen, the whole shebang
began unraveling.

I wish I had read the book before I
wrote about Maxwell Taylor in my own book The
Generals. Hersh confirms my view that Taylor was a snake, and that the
Kennedys (John and Robert) were taken in by him -- and that is one of the
reasons we wound up in Vietnam, as they all showed each other how tough they
were, and Taylor thought he had found a role for the Army in a nuclear
world.
