Cuba place on 14 April 1961. About 1,400 Cuban exiles disembarked at the Bay of Pigs, but failed in their attempt to overthrow Castro. In January 1962, Cuba was suspended from the Organization of American States (OAS), and later the same year the OAS started to impose sanctions against Cuba of similar nature to the US sanctions. The Cuban Missile Crisis occurred in October 1962. By 1963, Cuba was moving towards a full-fledged Communist system modeled on the USSR. During the 1970s, Fidel Castro dispatched tens of thousands of troops in support of Soviet-supported wars in Africa. He supported the MPLA

Silliman in command. After shakedown in Chesapeake Bay, "Invade" steamed to Casco Bay, Maine, for training 24 November 1944.
