MIAMI (AP) - The U.S. has released more of its classified history of the 1961 Bay of Pigs invasion of Cuba.
    
The release Monday comes in response to a lawsuit filed in April by the independent, Washington-based National Security Archive to declassify all five volumes on the failed CIA-backed 1961 invasion by Cuban exiles who hoped to overthrow Fidel Castro's fledgling government. One volume has yet to be released.
    
The newly released documents detail the close relationship between the U.S. and Guatemalan governments, where the exiles trained for the assault.
    
They show how then-Guatemalan President Miguel Ydigoras Fuentes even wanted his troops to participate in the invasion. When Ydigoras' unpopular, military-backed government faced a series of attacks from Guatemalan rebel forces, its officials asked the U.S. for napalm bombs. The request was denied.
