The Caribbean Peace Force (CPF), also known as the Eastern Caribbean Peace Force (ECPF), was an OECS mandated 350-member peacekeeping force operating in Grenada, from October 1983 to June 1985, after the Invasion of Grenada, codenamed Operation Urgent Fury, by the United States of America and several other nations in response to the illegal deposition and execution of Grenadan Prime Minister Maurice Bishop. On October 25, 1983, the United States, Barbados, Jamaica and members of the Organisation of Eastern Caribbean States landed ships on Grenada, defeated Grenadian and Cuban resistance and overthrew the military government of Hudson Austin.
