Newly declassified U.S. documents show a CIA operative accidentally fired on friendly pilots during the 1961 Bay of Pigs invasion of Cuba.
The documents also show U.S. officials authorized limited use of napalm on military targets and to protect the invasion's beachhead area.
In the report, two U.S. pilots described dropping bombs and napalm on Cuban troops that "left the convoy badly messed up."
Initially, officials hesitated to use napalm because it "'would cause concern and public outcry,'" the documents indicated. But by the second day of fighting, that notion "had gone by the board in favor of anything that might reverse the situation in Cuba in favor of the (exile) Brigade forces."
